Sewage purification filter system

Abstract

The invention discloses a sewage purification filter system which comprises a shell, wherein both sides of the shell are respectively provided with a water inlet and a water outlet; sewage enters the shell via the water inlet, sequentially flows through a flow-deflection conditioning zone, a multilayer filter system, an intermittent region, a facultative anaerobic precipitation region, a buffer region, an aerobic region, a secondary precipitation region and a water discharge tank, and finally flows out of the water outlet; the multilayer filter system sequentially comprises a solid particle filter layer, an organic matter filter layer and a pebble layer from top to bottom; an aerobic region filler is suspended in the aerobic region; and the bottom of the aerobic region is provided with a micropower aerating system. The system implements integrated treatment on rural domestic sewage, has favorable treatment effect, and can thoroughly remove toxic harmful condensates in domestic sewage, thereby enhancing the recovery and reutilization efficiency of domestic sewage, saving the water resources and lowering the economic investment cost. The system is suitable for popularization and application, has favorable safety performance, and satisfies the 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 and filtration system. 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 ...

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.
