      WSZ-A type modular 
      A, Process Description 
      WSZ-A-type device designed primarily for sewage and similar industrial organic wastewater treatment. The main processing means is the use of more mature biochemical treatment technology - contact oxidation, water quality of life according to the general water quality parameters, water BOD 20Omg / l, the effluent BOD 20mg / l index design, a total of six parts: ( 1) primary settling tank; (2) contact oxidation pond; and (3) secondary sedimentation tank; (4) pool disinfection, sterilization equipment; (5) sludge pond; (6) Fan Room, fan; 
      Now they are discussed below: 
      (1) the primary settling tank: First sedimentation tank equipment for the vertical flow sedimentation tank, sewage upflow velocity sedimentation of 0.6-0.7 mm / sec, sludge settling down with air to lift the sludge pond. (Note: WSZ-A O.5-5m3 / h without primary sedimentation tank) 
      (2) contact oxidation pond: artesian water after primary sedimentation tank for biological treatment to the contact, the contact tank is divided into three levels, with a total residence time of 1 hour or more. Hardened equipment contact oxidation time up to 6 hours, packing a new trapezoid filler. Easy conjunctiva, is not blocked. Packing specific surface area of ​​160m2 / m3, contact tank gas-water ratio of 12: 1. (Note WSZ-A 0.5-5T / h, the contact pool for two) 
      (3) secondary sedimentation tank: biochemical sewage flows to secondary settling tank, secondary settling tank for two only vertical flow sedimentation tank, they run in parallel. The flow rate was increased O.3-0.4 mm / sec. Mud using air lift to the sludge pond. (Note WSZ-A0.5-5mT / h, gravity sludge to sludge basin) 
      (4) pool disinfection and sterilization equipment: disinfection tank according to specifications: "TJI4-74" standard of 30 minutes, if the hospital sewage, sterilization tank to increase the residence time of 1.5 hours, using solid chlorine tablets dissolve in contact disinfection methods, disinfection devices can continue to change the dosage depending on the size of the water, reaching more water pay more drugs, less water and less dosing purposes. Other disinfection device can be formulated separately. (Note: If used for industrial wastewater disinfection and sterilization equipment can not pool) 
      (5) sludge pond: primary sedimentation tank, secondary sedimentation tank sludge all were raised to the sludge with air tanks WSZ-A of aerobic digestion. Serum return sludge pond to contact oxidation pool reprocessing. Digested sludge rarely, usually 1--2-year clean-up once. Suction truck cleaning method can be inserted into the bottom of the sludge from the sludge tank inspection hole, suction Sinotrans can. (WSZ-A 0.5-5T / h, anaerobic sludge digestion) 
      (6) Fan Room, Fan: fan room equipment WSZ-A is located above the pool disinfection, import with double soundproofing, air inlet muffler, fan filter, so no noise running. Fan with two sets of L-type blower, automatic alternating operation. Single wind turbine operating life of 30,000 hours or so.
