02 New rural domestic sewage treatment equipment Zhuyuan buried integrated equipment meets the standard discharge Weifang Zhuyuan Environmental Protection Equipment Co., Ltd., is a company dedicated to: domestic sewage treatment, aquaculture sewage, slaughter sewage, food processing sewage, industrial sewage treatment, hospital sewage treatment and other environmental protection equipment research and development, production, sales and various sewage treatment engineering design, installation, commissioning, technical consulting services in one of the environmental protection Equipment company. Integrated sewage treatment processes include A/A/O, SBR, oxidation ditch, A/O, biofilter, biological contact oxidation, anaerobic treatment (UASB, anaerobic fluidized bed), hydrolytic acidization+aerobic tank, AB method, biological turntable, etc. Different processes are used for different water quality and different treatment requirements. Integrated sewage treatment equipment At present, most of the domestic sewage treatment equipment processes in China use the activated sludge method and the biofilm method. The more mature technology of activated sludge in France is the A/O biological contact oxidation method, and the biofilm method is MBR membrane treatment technology. Both of these are more mature technologies for domestic sewage treatment at this stage. (1) A/O Series Sewage Treatment Equipment Product Introduction The company designs integrated sewage treatment equipment that meets domestic needs on the premise of combining domestic and foreign technologies. Its equipment mainly adopts A/O biological contact oxidation method. Production of carbon steel, stainless steel, FRP as the main raw materials of sewage treatment equipment, which removes BOD, COD, NH-N, suspended matter (SS) content is high, nitrogen and phosphorus content is higher than one. The equipment consists of a total of six parts (1) sewage pretreatment tank (2) working principle contact oxidation tank (3) two sink tank (4) disinfection tank (5) sludge tank (6) fan room equipment. 1. The pretreatment sewage of the conditioning tank enters the equipment through the water inlet, and the first pre-treatment is carried out. The grille pool is used to isolate large impurities and floating matter, and the sewage flows to the conditioning tank, which can not only adjust the water intake but also balance the water source. This is an important step before sewage treatment, and can improve the effect and efficiency of later sewage treatment. 2. Contact oxidation tank treatment In the oxidation tank, sewage first passes through a grade A biological pool (anaerobic pool), and uses the effects of hydrolysis, acidification and methanation of organic matter, removes organic matter in the wastewater, and improves the biochemicity of the sewage, which is conducive to subsequent aerobic treatment, and then enters the O-grade biological pool (aerobic pool), and uses aerobic microorganisms (including facultative microorganisms) to perform biological generation in the presence of oxygen Thank you for the resolution organic matter, making it stable and harmless for the next step of treatment. 3. The sedimentation tank treats the sewage treated by the oxidation tank and flows into the sedimentation tank (the second sedimentation tank) to further remove the sludge and suspended matter from the water. 4. Disinfection tank treatment The disinfection tank further disinfects the discharged clean water. An automatic chlorine dioxide generator is adopted to automatically control the dosage, so that the discharged clean water meets the discharge standard.
