A backwater well type rural sewage back seepage treatment device and method

Abstract

The backwater well type rural sewage reinfiltration treatment device of the present invention comprises a large bucket, a small bucket, a water inlet pipe, an overflow pipe, a water distribution plate and a water distribution pipe, the large bucket is provided with a water inlet pipe and an overflow pipe; the water distribution plate is located in the inner cavity of the small bucket Among them, the top of the water distribution plate is filled with filter packing; the lower end of the water distribution pipe extends through the water distribution plate into the water distribution cavity, the water distribution plate is provided with water distribution holes, and the vat is provided with water seepage holes. The sewage treatment method of the present invention includes: a). Selection and loading of fillers; b). Embedding of treatment devices; c). Filtration of sewage; d). Purification of sewage; e). In the sewage treatment device and method of the present invention, the sewage is filtered through the filler to realize the filtration of suspended particles in the sewage and the absorption of nitrogen and phosphorus elements. The treated sewage flows into the ground through the seepage holes, making it seep back into the ground and enter the natural environment. In the environment, it is directly used by animals and plants in the environment, and has the advantages of economy, high efficiency, energy saving and environmental friendliness.

Description

technical field [0001] The invention relates to a sewage treatment device and method, more specifically, to a backwater well type rural sewage back seepage treatment device and method. Background technique [0002] my country has a vast rural area, and rural sewage treatment is an urgent problem that needs to be solved at present. Most of the domestic sewage is untreated and discharged randomly, resulting in dark and smelly water in ditches and ponds, and mosquito breeding, which seriously affects the living environment and health of residents. At the same time, it will cause pollution of drinking water sources and eutrophication of lakes and rivers. Due to the different water quality in different places, the same sewage treatment equipment has different treatment effects on different water qualities. When the effluent water quality is not good, further advanced treatment is often required to make the treated water meet the standard. [0003] At the same time, as more and mo...

Problems solved by technology

[0003] At the same time, as more and more rural domestic sewage is discharged in a centralized manner, the supply of groundwater is insufficient, which is not conducive to the circulation of groundwater in rural areas, and cannot provide a good living environment for animals and plants. If domestic sewage can be fully utilized, it will be Its purification and infiltration into the ground will solve this problem
