Weifang Aerospace Environmental Protection Equipment Co., LtdHospital sewage treatment technologyThe situation is summarized as follows:

Characteristics of Hospital Sewage

Hospital wastewater contains some special pollutants, such as drugs xiaoduji、 Diagnostic agents, detergents, as well as a large amount of pathogenic microorganisms, parasite eggs, and various types of bacteria such as roundworm eggs, hepatitis bacteria, tuberculosis bacteria, and dysentery bacteria. In addition, hospital wastewater with isotope diagnosis and treatment rooms also contains radioactive substances such as radium-226, phosphorus, gold-198, iodine-131, etc. Compared with industrial wastewater and domestic sewage, it has the characteristics of small water volume and strong pollution. If left unchecked, it will inevitably pollute water sources and spread diseases.

2 Traditional Hospital Sewage Treatment Methods

2.1 shengwuOxidation method
　　Shengwu oxidation method, also known as activated sludge method, is the most commonly used traditional treatment method for various wastewater treatments. By using air blowing aeration, mechanical aeration, and other methods, a large number of filamentous bacteria, fungi, and other microorganisms in the sewage can reproduce. These microorganisms have the ability to adsorb and oxidize harmful substances in the sewage, thereby reducing the COD and BOD of the sewage and achieving purification effects. Some sewage treatment plants also use a combination of anaerobic and aerobic methods. During anaerobic processes, anaerobic microorganisms reproduce, nitrify, and adsorb harmful substances in water. Its disadvantage is that it generates a large amount of activated sludge and requires sludge treatment, which prolongs the treatment process, increases engineering costs, and causes secondary pollution to the air during the aeration process. There are many examples in this area in China, and Daqing Fifth Hospital is one of them (drum aeration method)^[1].
The commonly used shengwu oxidation methods include shengwu contact oxidation method, shengwu rotary table method, tower shengwu filter method, jet aeration method, and oxidation ditch method.
2.2 Chemical reagent method
The chemical agent method involves adding an appropriate amount of chemical agents to wastewater to oxidize harmful substances and achieve coagulation, adsorption, and precipitation. This method has gradually developed over the past thirty years after traditional biochemical methods.
①yelv Yelv is widely used for disinfection of tap water and hospital sewage due to its strong disinfection ability and low price. But Yelv is a yellow substance with a pungent odor, and cannot be produced anytime and anywhere. Storage and chlorination equipment are necessary. Yelv's dosing equipment has a complex structure, is prone to corrosion, and poses a high level of danger, which limits its use in urban or densely populated areas.
② Sodium hypochlorite solution is one of the most primitive disinfection methods. This method has convenient raw material sources, stable products, easy transportation, low equipment investment, low operating costs, easy management, safety, reliability, and will not produce sludge due to xiaoduji. It is widely used. However, sodium hypochlorite has weak disinfection ability and generates waste residue during the treatment process, which is gradually being replaced by other products.
③ Ozone method: Ozone is a strong oxidant, and adding an appropriate amount of ozone to wastewater oxidizes micro pollutants and various metal ions in the water. This method is more effective in treating hospital wastewater and has less secondary pollution. The disadvantage is that there are many supporting equipment, a large one-time investment, a large amount of equipment maintenance, and high electricity consumption, which increases the annual operating costs.

3 currently good methods for handling

3.1 CASS Process Biochemical Treatment
　　3.1.1 Characteristics of CASS process
The CASS pool has reduced its volume and achieved better results through technological innovation and optimized design. This method involves continuous inflow without aeration, resulting in a high concentration of organic matter in a state of hypoxia and anaerobic conditions, which inhibits the growth of aerobic bacteria and controls the sludge from expanding. The main reaction zone is divided into two parts: anoxic and aerobic, with periodic aeration, sedimentation, and skimming. During the sedimentation stage, no water is introduced, eliminating potential hydraulic interference and improving sludge characteristics and effluent quality. The ingredients are very complex and contain multiple pathogens bingdu、 Parasitic eggs and some harmful substances, hospital sewage with large changes in water quality and quantity^[2]It has stronger adaptability and better treatment effect, making it an ideal hospital sewage biochemical treatment method:
① The construction cost is low. The shengwu degradation, sludge settling, and wastewater discharge of CASS are all carried out in the same tank, without the need for regulating tanks, secondary sedimentation tanks, and sludge return equipment, which can greatly save investment, reduce land use, and lower operating costs. Generally, construction costs can be saved by 10% to 25%, and the land area can be reduced by 20% to 35%.
② Low operating costs. Due to periodic aeration, the concentration of dissolved oxygen in the tank decreases during the sedimentation and drainage stages. During aeration, the oxygen concentration gradient is large, the transfer efficiency is high, energy-saving *, and operating costs can be saved by 10% -25%.
③ High organic matter removal rate and good effluent quality. The CASS method not only effectively removes various organic pollutants from wastewater, but also has good denitrification and phosphorus removal functions. Make the investment in secondary treatment reach the water quality of tertiary treatment.
④ The CASS process is highly capable of achieving aerobic, anoxic, and anaerobic states in delayed aeration and cyclic circulation. For the treatment of hospital sewage, it is necessary to consider the presence of infectious diseases and pathogenic bacteria in the sewage. Therefore, the treatment method of ordinary sewage purification tanks cannot be used. Anaerobic and facultative combined treatment should be adopted, and a series of physical, chemical, and biochemical principles should be used to precipitate, decompose, engulf, and kill organic matter, bacteria, and bacteria in infectious disease sewage^[3]The CASS method can effectively meet this requirement.
⑤ The CASS method adopts delayed aeration, resulting in low sludge yield, good dewatering performance, easy treatment, and reduced sludge treatment costs. The new type of underwater aeration equipment replaces the traditional blowing aeration method, with flexible use, simple system, and no noise pollution.
⑥ The management unit operates reliably. There are relatively few types and quantities of equipment in sewage treatment plants, and the control system is relatively simple. Floating automatic lifting skimming devices and special decanters are used to discharge water during the inlet process, and the lifting of the water permeable device is automatic. Ensure stable water output.
　　3.1.2 Processing effect
It can be seen from the water quality before and after the sewage treatment of Friendship Hospital, which adopts the biochemical method for secondary treatment, that the hospital's sewage treatment effect is very significant, and all indicators can meet the standards and are far below the national standards^[4]As shown in Table 1:

At present, there are more than 270 sewage treatment plants in the United States, Canada, and Australia that use the CASS method. Table 2 shows the treatment results of sewage treatment plants in the United States and China using the CASS method.

　　3.2 Chlorine dioxide disinfection
　　3.2.1 Characteristics of Chlorine Dioxide Disinfection
Chlorine dioxide is an efficient, broad-spectrum, safe, fast, multifunctional, long-lasting, and easy to store and use fungicide. It is classified as safe grade A1 by the World Health Organization (WHO) and has been approved by the US Environmental Protection Agency (EPA) and the US Food and Drug Administration (FDA) for use in hospitals, food processing, and other sectors.
The commercial chlorine dioxide products produced domestically and internationally are mainly stable chlorine dioxide solutions, and there are also a small number of solid chlorine dioxide products such as slow-release bulk, gel like particles, microencapsulated powders, etc. In recent years, chlorine dioxide method has become very popular in the domestic sewage treatment industry and has shown good results in hospital sewage treatment. The advantages of using chemical chlorine dioxide disinfection for treating hospital wastewater are:
①ClO₂It can kill all microorganisms, including bacterial colonies, cell spores, fungi, mycobacteria, and bingdu. It can effectively destroy trace organic pollutants in water. Can effectively oxidize some reduced metal ions in water, such as Fe²⁺、Mn²⁺、Ni²⁺Wait. It is less affected by pH, has a killing effect on algae, and can also reduce the color, turbidity, and odor of aqueous solutions. Its effect is 5 times that of sodium hypochlorite. Not forming significant organic halides in sewage treatment is an ideal choice for hospital sewage treatment^[5].
② Chlorine dioxide has a more effective disinfection effect on Bingdu than ozone and Yelv, reacts quickly with sewage, and has a dissolution time of 1/2-1/4 of chlorine, which can be shortened from 1 hour to 0.5 hours. The contact tank can be reduced to half of its original size, greatly saving investment.
　　3.2.2 Processing effect
The Chengguan Town Health Center in Neihuang County, Henan Province discharges about 500 tons of sewage per day. Using a chemical chlorine dioxide generator to treat hospital wastewater. The use of chlorine dioxide generators does not require further biochemical treatment, and can achieve emission standards for bacterial count, COD, and other indicators, greatly saving the investment and daily operating costs of hospital sewage treatment facilities. The treated hospital wastewater meets the discharge standards^[6].
　　4 Conclusion

To determine the hospital sewage treatment process, it is not only necessary to achieve the purpose of disinfection and sterilization, but also to consider the requirements of sewage discharge and the functional zoning of the receiving water environment for water quality. Starting from January 1, 1998, hospital sewage should comply with the "Comprehensive Wastewater Discharge Standard" (GB8978-96), which puts higher requirements on hospital sewage treatment. According to the standard
According to relevant requirements, using chemical chlorine dioxide disinfection or CASS process to treat hospital sewage can adapt well to this change. Compared with corresponding treatment methods, it has good effects, low investment, convenient management, low operating costs, and practical technology. It is technically and economically competitive, and is currently the preferred method for hospital sewage treatment that integrates social, economic, environmental, and ecological benefits.
