Runhe Environmental Protection Warm ReminderConstruction requirements for processing stations 9.1 Site selection, safety distance, and protective isolation requirements for processing stations The selection of processing station location should be determined based on factors such as hospital overall planning, outlet location, environmental hygiene requirements, wind direction, engineering geology, maintenance management, and transportation. 9.1.1 The location of hospital sewage treatment structures should be in the downwind direction of the prevailing summer wind direction in the local area of the hospital building. 9.1.2 The hospital sewage treatment facilities should maintain a certain distance from buildings such as wards and residential areas, and should be equipped with green protection belts or isolation belts. 9.1.3 A fence or enclosed facility should be set up around the sewage treatment plant, with a height not less than 2.5 meters. 9.1.4 The sewage treatment plant should have the possibility of expansion; Convenient for construction, operation, and maintenance. 9.1.5 The sewage treatment plant should have convenient transportation, water and electricity conditions; Convenient for sewage discharge and sludge storage and transportation. 9.1.6 Sewage treatment plants in infectious disease hospitals and comprehensive hospitals with infectious disease wards should have their production management buildings and living facilities centrally arranged, with reasonable locations and orientations, and should be strictly isolated from treatment structures and buildings. 9.2 Design requirements for processing structures and buildings 9.2.1 Processing structures, buildings, and main equipment should be divided into two groups, with each group calculated at 50% load. 9.2.2 Anti corrosion and anti leakage measures should be taken for the treatment of structures and buildings; Ensure processing effectiveness, safety and durability, easy operation, and facilitate labor protection for operators. 9.2.3 Sewage treatment structures should be equipped with drainage facilities, and the discharged water should be treated by reflux. 9.2.4 In cold regions, anti freezing measures should be taken for handling structures. When heating, the indoor temperature of the structure can be designed to be 5 ℃; The indoor temperature of the dosing room, inspection room, and duty room can be designed at 15 ℃. 9.2.5 Elevated structures should be equipped with appropriate safety measures such as railings, anti slip slides, and lightning rods. 9.2.6 It is generally recommended to use gravity flow discharge for sewage treatment plant drainage, and if necessary, a drainage pump station can be installed. 9.3 Auxiliary facilities and related requirements of the treatment station 9.3.1 In the design of the sewage treatment station, appropriate space should be reserved according to the overall plan. 9.3.2 According to the scale and specific conditions of the hospital, the processing station should be equipped with facilities such as duty rooms, laboratory rooms, control rooms, and liaison. 9.3.3 Sewage treatment stations may set up storage areas for sludge, waste residue, and medical waste at appropriate locations as needed, but strict sealing measures must be taken for the above garbage. 9.3.4 The processing station should have necessary measuring, safety, and alarm devices.

The following is the basic process of sewage treatment plant treatment technology: Modern sewage treatment plant sewage treatment technology can be divided into primary, secondary, and tertiary treatment according to the degree of treatment. Primary treatment mainly removes suspended solid pollutants in sewage, and most physical treatment methods can only meet the requirements of primary treatment. After primary treatment, sewage can generally remove about 30% of BOD, which does not meet the discharge standards. The first level processing belongs to the preprocessing of the second level processing. Secondary treatment mainly removes colloidal and dissolved organic pollutants (BOD, COD substances) in sewage, with a removal rate of over 90%, to meet the discharge standards for organic pollutants. Third level treatment, further processing of recalcitrant organic matter, nitrogen, phosphorus, and other soluble inorganic substances that can lead to eutrophication of water bodies. The main methods include biological nitrogen and phosphorus removal, coagulation precipitation, sand ratio, activated carbon adsorption, ion exchange, and electroosmotic analysis. The entire process involves the raw sewage that has been subjected to coarse grid filtration being lifted by a sewage lifting pump, then passing through a grid filtration or screening device, and finally entering a sedimentation tank. The sewage that has undergone sand water separation enters the primary sedimentation tank, which is the first level treatment (i.e. physical treatment). The effluent from the primary sedimentation tank enters biological treatment equipment, including activated sludge and biofilm processes (where the reactor of the activated sludge process includes aeration tanks, oxidation ditches, etc., and the biofilm process includes biological filters, biological turntables, biological contact oxidation, and biological fluidized beds). The effluent from the biological treatment equipment enters the secondary sedimentation tank, and the effluent from the secondary sedimentation tank is disinfected and discharged or enters the third level treatment. The first level treatment ends at this point, which is the second level treatment, and the third level treatment includes biological denitrification. Phosphorus removal method, coagulation sedimentation method, sand filtration method, activated carbon adsorption method, ion exchange method, and electrodialysis method. Part of the sludge from the secondary sedimentation tank is returned to the primary sedimentation tank or biological treatment equipment, while another part enters the sludge concentration tank and then enters the sludge digestion tank. After passing through dewatering and drying equipment, the sludge is reused.
