Underground domestic sewage treatment equipment

Introduction WSZseries devices are equipments that using currently mature biological contact oxidation to treat domestic sewage and similar industrial waste water, water quality design parameters of wastewater is calculating according to the water quality of domestic sewage, the average influent BOD is 200mg / L then effluent BOD up to 20mg / L, this equipment has a significant treatment effect on the BOD, COD, ammonia and other organic pollutants. The whole process mainly consists of five parts: adjust pool (not included in the equipment ); primary sedimentation tanks; contact oxidation pool; secondary sedimentation tanks; disinfected pool. Device characteristics 1. Size of each unit are digital module, all set of equipment can be carried out different combinations according to different occasions, and to achieve maximum flexibility. 2. Can be buried settings, not covering the surface area and equipment above can set green area or sidewalks road, etc.; no effect on the surrounding environment, no protective isolation spacing, no heating insulation. 3. high processing efficiency, good cleaning level, small consumption and management costs, easy to operate. 4. Little effect on the surrounding environment, a fully enclosed structure, buried underground, no noise, no smell when processing. 5. Without specialized personnel management, the device has automatic control systems, this equipment is reliable. The treatment scope of application 1.Hotels, restaurants, nursing homes, hospitals. 2. Residential areas, private housing, holiday park. 3. Stations, airports, port terminals and ship. 4. Factories, mines, military, tourist, scenic. 5. And kinds of industrial wastewater similar with domestic wastewater.
