What disinfectant should be used for hospital sewage treatment? You will understand after reading this article

Chlorine dioxide exhibits excellent bactericidal and viral killing effects against more than 10 bacteria and viruses, including Escherichia coli, Salmonella, Staphylococcus aureus, Bacillus subtilis, and hepatitis B virus. Experimental studies have shown that when the bactericidal effect of chlorine dioxide gas in the air is determined using the natural colony method, the time required to achieve a bactericidal rate of over 90% is 48 hours for beef-based (bacteria) and 28 hours for potato-based (mold). At a concentration of 109 μg/m³, the time is 24 hours for beef-based and 8 hours for potato-based. At a concentration of 1150 μg/m³, the time is 10 minutes for beef-based and 3 minutes for potato-based. Specially designed and prepared adsorbent-type solid chlorine dioxide can be broadly classified into three types: long-acting, medium-release, and fast-release. Long-acting solid chlorine dioxide automatically and slowly releases low concentrations of chlorine dioxide gas over a relatively long period, effectively killing germs and mold in the air, removing odors, and preventing indoor items from becoming moldy in humid air. Simultaneously, the atomic oxygen released during its decomposition freshens the air and poses no harm or side effects to the human body. It is also colorless and odorless, which is unmatched by other types of gaseous disinfectants. Fast-release solid chlorine dioxide has a shorter effective time but a faster release rate, making it suitable for special environments requiring rapid sterilization but not necessarily a long-lasting effect. Medium-release solid chlorine dioxide products have a longer effective release time than fast-release but shorter than long-acting products, generally 2-4 weeks, but with a wide adjustable range and broad applicability. Specially formulated solid chlorine dioxide products can also have a delayed release time. Utilizing its automatic delayed release function, it can effectively kill moldy microorganisms remaining in the air and attached to the surface of items inside sealed bags, protecting items in boxes, crates, and bags from mold growth. This characteristic can be utilized to develop a series of new solid chlorine dioxide daily chemical products with superior performance.

Solid chlorine dioxide is a solid carrier chlorine dioxide product. The addition of a special slow-release agent enables it to slowly release a certain amount of chlorine dioxide gas within a certain period of time, thus ensuring that the product is always strictly controlled for safe, effective, and environmentally friendly use. In particular, the two-component adsorption type solid chlorine dioxide can control the onset time, effective release time, and effective release amount of its sterilization and disinfection. This characteristic gives it a very broad application prospect in the field of daily chemical products [196]. We can develop a series of special solid chlorine dioxide daily chemical products with different release characteristics for different objects and different uses.

(1) Research results on air fresheners show that chlorine dioxide concentrations below 3000 μg/m³ are not only harmless to the human body, but also beneficial. Low concentrations of chlorine dioxide molecules in the air can effectively kill microorganisms and bacteria, protecting the human body from bacterial and other microorganisms and infectious diseases. Furthermore, it is a recognized environmentally friendly substance. This is because after killing a considerable range of bacteria, viruses, protozoa, and other microorganisms in the air, it can reduce potentially carcinogenic organic compounds or harmful byproducts and transform them into safe and ordinary inorganic salts. Solid chlorine dioxide used for air sterilization releases a maximum of 600 μg/m³ of chlorine dioxide gas into the air, far below the safe value of 3000 μg/m³. Therefore, it can be processed into a high-performance next-generation air purifier product. It is colorless and odorless. Placing it in places where people frequently live and work can effectively protect people's health, prevent indoor items from getting moldy during the humid rainy season, remove odors from the air, and even freshen the air by releasing a small amount of atomic oxygen. Its effect is much better when used in conjunction with home appliances than when used alone. Long-lasting solid chlorine dioxide products designed for air conditioning, placed in the air ducts of air conditioners, release chlorine dioxide gas that is evenly distributed throughout the room with the cool air blown out of the air conditioner. This greatly enhances the air purification effects of solid chlorine dioxide, such as sterilization, mold prevention, and deodorization, and the released atomic oxygen also freshens the air, preventing air conditioning sickness. Therefore, as a novel gaseous daily health care product, it will undoubtedly bring a new enjoyment to people's lives, with a huge future market. It can be widely used in homes, office buildings, hotels, or other public places that require air sterilization, disinfection, and deodorization. It can also be given various pleasant fragrances and can be widely used in various places and industries that require indoor air sterilization, disinfection, and deodorization.

(2) Medical disinfectants using long-acting solid chlorine dioxide can be developed for use in hospitals and inpatient wards. Using this product not only effectively kills airborne germs and reduces the spread of viruses and bacteria transmitted through the air, but also has a long effective period, is easy to use, and has no odor, greatly improving the hospital environment at a low cost. Fast-release solid chlorine dioxide can quickly kill viruses within 30 minutes and maintain its effect for a certain period, making it suitable for use in operating rooms requiring rapid sterilization. Medium-release solid chlorine dioxide can also be made into energy-free medical sterilization cabinets for daily sterilization of medical devices, at a much lower cost than electric sterilization cabinets . It can even be made into small, portable sterilization boxes for daily sterilization of medical devices by visiting doctors, which is very useful for remote areas, rural areas, and military field hospitals and medical stations.

(3) The sterilization and disinfection cabinet is a special solid chlorine dioxide sterilization and disinfection cabinet developed using slow-release technology. It can be widely used in homes, hotels, and service industries such as beauty salons, hairdressers, and catering for the disinfection and sterilization of various supplies, utensils, instruments, and tableware. Because it uses slowly released chlorine dioxide gas for sterilization and disinfection, it is very convenient to use and the cost is much lower than that of electric sterilization cabinets . Using a specially formulated solid chlorine dioxide agent, this sterilization cabinet can also protect the dishes, food, or other easily moldy items placed in the cabinet from mold and deterioration for a long time at room temperature. It combines the functions of a sterilization cabinet and a refrigerator, and its cost performance is far superior to that of a sterilization cabinet and a refrigerator.

(4) Sterilization boxes and bags, because they use solid chlorine dioxide technology for sterilization, do not require electricity. If made into lightweight sterilization boxes or bags, they can be carried around and used anytime. They are very convenient for sterilizing and disinfecting small amounts of personal items, food, and clothing when traveling. They are suitable for travel, fieldwork, military operations, ocean shipping, and long-distance transportation. In particular, portable sterilization bags have a very broad application prospect in the tourism market.

(5) As an anti-mold agent , experiments have shown that chlorine dioxide molecules are more effective at killing mold than other bacteria. Special anti-mold agents prepared using solid chlorine dioxide can be used not only in cabinets, boxes, and bags, but also in homes, warehouses, and damp basements. They not only have excellent anti-mold effects, but also have a long effective lifespan and low cost. They can be widely used in manufacturers, distributors, material storage and transportation centers, as well as in long-distance freight vehicles, ships, and various shopping malls, bookstores, and libraries. The market capacity is also enormous. Specially designed small packages of solid chlorine dioxide tablets can replace the commonly used anti-mold agents currently on the market, such as mothballs and naphthalene balls (which have been medically proven to be carcinogenic), by placing them in home wardrobes and boxes to prevent clothing and books from becoming moldy. Furthermore, the released chlorine dioxide gas is not carcinogenic and has no other side effects. They can even be stored in sealed boxes and jars containing food or other easily moldy items to kill moldy microorganisms and protect food from mold growth.

(6) Adding specially formulated slow-release chlorine dioxide to dishwashing liquid imparts excellent bactericidal properties. Only 1/200,000 of the chlorine dioxide in the cleaning solution is needed to kill 100% of various spore-forming bacteria within 5 minutes . Adding a small amount of powdered solid chlorine dioxide directly to various detergents and laundry powders achieves the same effect; the actual cost increase for 400g of laundry powder is only a few cents, yet the effect is vastly different.

Many countries, especially Japan, have developed a series of detergents and disinfectants containing stable ClO₂ ( referred to as detergents and disinfectants), including liquid, powder, and detergent/disinfectant soaps. These detergents and disinfectants are stable, easy to use, and can be applied by soaking, rinsing, or spraying, followed by a final rinse with tap water. Stable ClO2 detergents and disinfectants are characterized by strong detergency, good cleaning and disinfection effects, ease of use, no damage to fabrics or human body, and no environmental pollution. They can be widely used in homes, restaurants, hotels, bathrooms, and food processing plants for washing fruits, vegetables, kitchen utensils, tableware, bathtubs, and walls, providing excellent anti-mildew and antibacterial effects. Long-term use is harmless to human body and environmentally friendly, making them a promising new type of detergent.

(7) The specially formulated powdered slow-release solid chlorine dioxide in the antibacterial skin cream can also be added to various skin creams, soaps, and toothpastes to give them a unique and good antibacterial effect. In particular, its excellent deodorizing function can also be used to develop various special antibacterial and deodorizing products for special purposes.

(8) Even more remarkable than the bactericidal effect of chlorine dioxide is its excellent deodorizing effect. It can oxidize H₂S _, SO₂, and thiols into sulfuric acid or sulfonic acid for removal, and the decomposed atomic oxygen can dehydrate ammonia water to become N₂ . Therefore, a special solid chlorine dioxide deodorizer can be developed and placed in toilets, public restrooms, and other public places prone to odors. Experiments have shown that solid chlorine dioxide can release chlorine dioxide gas above 0 ° C and can effectively disinfect, sterilize, and deodorize above 10 ° C, thus it can also be used in refrigerator compartments. Specially designed solid chlorine dioxide refrigerator deodorizers not only deodorize but also have anti-corrosion and preservation functions.

(9) Special food preservation agent: Because solid chlorine dioxide special food preservation agent kills moldy microorganisms in the air and attached to the surface of food by continuously releasing the effective ingredient chlorine dioxide, it protects the food from the outside . Therefore, food protected by solid chlorine dioxide can be preserved for a long time without adding preservatives, and there are no side effects.

Solid chlorine dioxide, especially specialized solid chlorine dioxide products developed for specific applications, has garnered significant attention due to its superior broad-spectrum bactericidal, disinfectant, deodorizing, mildew-preventing, and air-freshening properties. It is poised for widespread use and possesses enormous market potential in the daily chemical industry. Furthermore, its high-tech content, unique environmental friendliness, controllability, and convenience have made it increasingly popular. Its replacement of existing chlorine-based disinfectants in my country as the dominant disinfectant in the early 21st century is an inevitable trend. The development and research of specialized solid chlorine dioxide products for daily chemical use not only provides a new development space for the daily chemical industry but also offers a new direction for the chlorine dioxide industry itself.
