Domestic sewage distribution well

Abstract

The invention relates to a domestic sewage distribution well. An adjustable overflow weir is arranged at the upper part of an overflow distribution well; the outside of the overflow distribution well is a well wall of the overflow distribution well; the well wall is in a spirochete shape; an inner cavity of the overflow distribution well becomes bigger gradually from top to bottom; an annular water outlet pipe is arranged on the outer side of the well wall of the overflow distribution well; the adjustable overflow weir is a movement-adjustable weir plate and is 1,500mm in length, and the adjustable scope of the adjustable overflow weir is 500mm; a crest of the weir is in the same height with the center of the annular water outlet pipe; a plurality of filter screens are arranged in the inner cavity of the overflow distribution well. The domestic sewage distribution well has the advantages that a structure is simple, the decontamination effect is good, the reaction is sufficient, a contact space is large, and no power consumption exists; the annular water outlet pipe is arranged on the outer side of the overflow distribution well, so that microorganisms have the enough contact space and sufficient digestion time for organisms.

Description

technical field [0001] The invention relates to a decentralized farmer domestic sewage treatment device, in particular to a domestic sewage distribution well. Background technique [0002] Rural domestic sewage is the sewage produced by households in villages and towns from washing, bathing, kitchen cooking, excrement and its flushing, etc. It contains a large amount of organic nitrogen. Such pollutants are brought into rivers, leading to many ecological and environmental problems such as serious eutrophication of rural water bodies, and the overgrowth of blue-green algae and aquatic plants. In aquaculture water bodies, fertilization and feeding have long been a normal farming method. A large amount of input of foreign nitrogen-containing substances often causes nitrogen accumulation or nitrogen pollution in aquaculture water. On the other hand, it is due to the accumulation of organic nitrogen and inorganic nitrogen products formed by the metabolites of aquaculture animals...

AI Technical Summary

Problems solved by technology

In the aquaculture water, whether it is the enrichment of organic nitrogen or the accumulation of inorganic nitrogen, it will cause nitrogen pollution in the aquaculture water and cause poor water quality.
