Integrated civil sewage treatment system

Abstract

The invention discloses an integrated civil sewage treatment system. The integrated civil sewage treatment system comprises a shell, wherein a water inlet and a water outlet are formed in two sides of the shell; sewage enters the shell from the water inlet and then successively flows through a baffling adjusting region, a multi-layered filtering system, a first settling tank, a fine filtering tank, an anaerobic settling region, a heat exchange region, a second settling tank and a water outlet pond, and finally flows out from the water outlet; and the multi-layered filtering system successively comprises a solid particle filtering layer, an organic matter filtering layer and a pebble layer from top to bottom. By the integrated civil sewage treatment system, integrated treatment on civil life sewage is realized effectively, the treatment effect is good, poisonous and harmful substances and condensation products in civil life sewage can be removed thoroughly, therefore, the recycling efficiency of the civil life sewage is improved, water resources are saved, the economic investment cost is reduced, and actual use requirements are met.

Description

technical field [0001] The invention relates to an integrated civil sewage treatment system and belongs to the technical field of domestic sewage treatment. 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 include biolo...

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 the treated sewage still has serious toxic and harmful and condensate (especially kitchen and laundry sewage); in addition, in the prior art, the investment in rural sewage treatment equipment is relatively large, and the operating cost is too high. High, not suitable for promotion and use
