Rural domestic sewage integrated advanced treatment device and sewage treatment method

Abstract

The invention discloses a rural domestic sewage integrated advanced treatment device. The rural domestic sewage integrated advanced treatment device comprises a grit tank, an anaerobic tank, an anoxic tank, an aerobic tank, a membrane biological reaction tank and a baffling type autotrophic denitrification filter tank which are sequentially connected along the sewage treatment direction; the baffling type autotrophic denitrification filter tank comprises a sewage treatment area for filtering sewage and a clean water tank communicated with a water outlet of the sewage treatment area, and partition plates are arranged in the sewage treatment area in the vertical direction so as to divide the sewage treatment area into a plurality of treatment chambers; and each treatment chamber is filled with an autotrophic functional filler for providing electron donors for microorganisms in the sewage, each partition plate is provided with a connecting section for communicating the adjacent treatment chambers, and the connecting sections on the adjacent partition plates are arranged in a staggered manner, so that the sewage in the sewage treatment area flows in an S-shaped flow direction. Under a same occupied area, the flow path of the sewage is maximized, the denitrification effect is improved, only a small filter material area is needed for completing the same water treatment amount, and the filter material cost is saved.

Description

Technical field [0001] The present invention relates to the field of environmental engineering, in particular the integration of rural sewage advanced treatment and sewage treatment equipment. Background technique [0002] With the new rural construction and ongoing development, rural sewage treatment has become the top priority of building a new countryside. At present, rural water pollution is serious, and some rivers, which can not be used as drinking water sources, can not even meet the requirements of farming, irrigation. Most of the rural drinking water has not been monitoring authorities, a lot of people can not drink the water clean and compliance. So rural sewage treatment and wastewater treatment and recycling has become an urgent problem to be solved. Sewage, livestock waste water and other water features villagers generated in daily life is the high-containing organic pollutants, and more pathogenic microorganisms suspended matter. If not effectively controlled, not o...

Problems solved by technology

Discharge of the scattered treated sewage into the water body is also a burden on the water body, and may exceed the pollutant capacity of the water body environment in the long run

However, the existing baffled self-supporting denitrification filter in the water plant often needs to be equipped with many grids to meet the treatment water volume, which occupies a large area, has high backwash frequency and high energy consumption, so it needs to be solved urgently.
