Sewage purification treatment device

Abstract

The invention discloses a sewage purification treatment device. The device comprises a casing, wherein a water inlet and a water outlet are formed in two sides of the casing; sewage sequentially passes a deflection flow adjustment zone, a multi-layer filtering system, an intermittent zone, a facultative anaerobic precipitation zone, a buffer zone, an aerobic zone, a secondary precipitation zone and a water outlet tank after entering the casing through the water inlet and then flows out from the water outlet; the multi-layer filtering system sequentially comprises a solid particle filtering layer, an organic matter filter layer and a pebble layer from top to bottom, aerobic zone filler is suspended in the aerobic zone, and a micro-power aeration system is arranged at the bottom of the aerobic zone. The sewage purification treatment device can realize integrated treatment on life sewage in rural areas, has a good treatment effect, can completely discharge toxic and harmful substances and condensate in life sewage and further improves the recycling efficiency of life sewage, water resources are saved, economic investment costs are reduced, and the device is suitable for popularization and application, has better safety performance and meets actual use requirements.

Description

technical field [0001] The invention relates to the technical field of domestic sewage treatment equipment, in particular to a sewage purification treatment device. Background technique [0002] With the significant improvement of people's living standards, the requirements for sewage treatment have also increased. After 1990, my country's sewage treatment has developed rapidly, and the growth rate of sewage treatment volume is 2.3 times that of the world. With continuous improvement, China's sewage treatment industry has grown rapidly, and the efficiency of township sewage treatment has also continued to improve. [0003] China's lack of water resources and water pollution seriously restrict the healthy and sustainable development of my country's overall economy, especially in rural areas. Regional water environment governance has become an important part of my country's comprehensive environmental governance. At present, the rural sewage treatment technologies mainly inclu...

AI Technical Summary

Problems solved by technology

At present, the rural sewage treatment technologies mainly include biological contact oxidation method, activated sludge method, biological filter, etc., but due to the serious flood of rural domestic sewage impurities, the simplicity of the existing sewage treatment process and the backward technology, the actual operation of the treatment process The treatment effect on sewage is seriously insufficient, and there are still serious toxic and harmful substances and condensates in the treated sewage; in addition, in the prior art, the investment in rural sewage treatment equipment is relatively large, and the operating cost is too high, so it is not suitable for popularization and use.
