School domestic sewage treatment equipment

Equipment craft:

WSZ-A type of equipment design is mainly aimed at sewage and anything like organic wastewater treatment industry. The main processing method is used at present the mature biochemical treatment technology, contact oxidation method, water quality parameters according to the general life water quality, water BOD 20 Omg/l, water BOD 20 mg/l index design, there is a total of six is composed of: (1) the pond early; (2) contact oxidation pool; (3) the second pond; (4) disinfection pool, disinfection device; (5) sludge pool; (6) the wind machine room, fan;
Now discussed as follows:
(1) beginning pond: early equipment for vertical flow pond sediment basins, sewage in the rise of traps for velocity 0.6 0.7 mm/SEC, the precipitation down with air to mention sludge sludge pool. (note: WSZ-A o. 5-5 m3 / h do not set beginning pond)
(2) contact oxidation pool: beginning the heavy water after their biochemical treatment to contact pool, contact pool three levels, always stay time for 1 hour or more. Enhanced equipment contact oxidation time to six hours, packing for novel acme packing. Easy conjunctiva, don't blocked. Packing surface area for 160 m2 / than m3, contact pool water in about 1 than gas. (note WSZ-A 0.5-5 T/h, contact pool for level 2)
(3) the second pond: after flow to the sewage biochemical second pond, the second pond for two vertical flow sediment basins, they run in parallel. Rising velocity for o. 3-0.4 mm/SEC. Row mud USES air up to sludge pool. (note WSZ-A0.5-5 mT/h, sludge to pool their sludge)
(4) sterilization tank and disinfection device: sterilization tank according to the standard: "TJI4-74" standard for 30 minutes, if the hospital sewage, sterilization tank can increase stay time to 1-1.5 hours, by using solid contact the disinfection of chlorine dissolved way, sterilization device can according to the size of the water yield changes dosage, achieve much more medicine water, less water add less the purpose of medicine. Other disinfection device can be made. (note: if used in industrial wastewater disinfection pool and disinfection devices can not)
(5) sludge pond: beginning the pond, the second pond with all of the sludge are air to WSZ-A mention of the sludge in the pool for good oxygen digestion. Sludge pool of clear fluid backflow to contact oxidation in the pool before the processing. After few surplus sludge digestion, general 1-2 years clean again. Cleaning method can be adopted from the sludge pond DE la villette absorption reach into the hole bottom sludge check, suction sinotrans can. (WSZ-A 0.5-5 T/h, sludge the anaerobic digestion)
(6) the wind machine room, fan: equipment WSZ-A room of the wind in the upper part of the sterilization tank, import use double deck sound insulation, wind path have muffler, fan filter, so no noise when running. Fan the radio 2 L ROM watts blower, it can automatic alternate operation. Single machine fan operation life 30000 hours or so.
