Key medical waste prevention is to kill all kinds of bacteria in sewage kill pathogens pharmaceutical purposes are eight main: (1) bleaching powder; (2) bleached crystal; (3) sodium hypochlorite; and (4) of liquid chlorine; (5) Ozone; (5) electrolytic chlorine dioxide; (7) the chemical chlorine dioxide; (8) UV disinfection. Medical waste water treatment station used chlorine or sodium hypochlorite disinfection disinfection of medical wastewater treatment plants, sewage to a small hospital also uses bleach disinfection. By chlorine disinfection, application chlorinator to time quantitative chlorination method put chlorine. Rich students Dongguan People's Hospital medical waste project after primary treatment of sewage medical wastewater treatment process, the amount of chlorine can be set at 20-30mg / L; after secondary treatment of sewage, the amount of chlorine can be set at 10 ^ -20mg / L . The actual amount of chlorine residual chlorine in the export volume of sewage to be adjusted. Sodium chlorate solution using an electrolytic sterilization method can be a high concentration, resulting in sodium hypochlorite solution depth. Sodium hypochlorite solution can be applied directly, using the siphon method put to disinfect sewage when determining the amount of chlorine reference to chlorine disinfection. Use of ozone disinfection by ozone disinfection of medical waste can also be effectively stop the virus inactivation. UV disinfection is subject transmittance for medical waste water treatment is not ideal. The principle of a medical waste disposal, emissions from process control principles to control the whole process of hospital wastewater generation, handling, 2, minimization principles. Strict hospital within the health and safety management system, occurs in sewage and dirt at the source strict control and separation of sewage and hospital wards Guangdong Medical wastewater sewerage respectively, that source control, decontamination triage. The hospital is strictly prohibited and dirt free to dispose of sewage discharged into the sewer. 3, in situ treatment principles. To prevent hospital sewage contamination during transportation and hazards in hospitals must situ treatment. 4, classification guidelines. According to the hospital the nature, scale, sewage discharge destination and regional differences in hospital sewage processing guidance. 5, compliance with the principle of combining risk control. Full account of the basic requirements of general hospitals and infectious disease hospital wastewater discharge standards, while strengthening risk control awareness, improve the ability to respond to emergencies from the technology, construction and supervision of management. 6, ecological security principles. Effective removal of hazardous substances in wastewater, reducing disinfection byproducts during processing to produce and control the excessive chlorine in water, protect the environment safe.
