Embodiment Construction

[0032] Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements.

[0033] Please refer to Figure 1-10 , the domestic sewage treatment system includes an integrated sewage treatment equipment 1, a grid grit chamber 2, a sludge drying pond 3 and a constructed wetland 4.

[0034] The integrated sewage treatment equipment 1 includes a box body 1, the outer dimension of the box body 1 is 7.5m×2m, and the height is 2.5m, so the volume is small. The box body is an integrated structure spliced ​​by 304 stainless steel, so it has a long service life. According to the requirements of water quality and discharge standards, each processing unit can be spliced ​​and designed, and the process selection is flexible.

[0035] The inside of the box body 1 is divided into an anaerobic pool 11, an anoxic pool 12, a biological contact oxidation pool 13, a sedimentation pool 14, and a clean water pool 15 c...

Abstract

The invention discloses a domestic sewage treatment system which comprises integrated sewage treatment equipment and further comprises a grid sand setting tank, a sludge drying tank and an artificial wetland. The integrated sewage treatment equipment comprises a box which is of an integral structure formed by splicing 304 stainless steel, the inside of the box is divided into an anaerobic tank, an anoxic tank, a biological contact oxidation tank, a sedimentation tank and a clean water tank which are connected sequentially, the anaerobic tank is connected with the grid sand setting tank, the sedimentation tank is connected with the sludge drying tank which is connected with the grid sand setting tank, a flow incoming system connected with the biological contact oxidation tank is arranged in the sedimentation tank, an inclined pipe filler is arranged in the sedimentation tank, and the clean water tank is connected with the artificial wetland. The domestic sewage treatment system is low in manufacturing cost, simple to maintain, capable of saving engineering land occupation and stable in outgoing water quality.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a domestic sewage treatment system. Background technique [0002] With the development of social economy and the advancement of industrialization, water pollution incidents have become more and more frequent. For this reason, the country has paid more and more attention to the environment. According to the requirements of the State Council's "Twelfth Five-Year Plan", by 2015, the average sewage treatment rate of counties will reach 70%, and the average sewage treatment rate of towns will reach 30%. There is still a lot of room for development in the remaining 30% and 70%. At the same time, according to the "Water Pollution Prevention and Control Action Plan" issued by the State Council in 2015, it is necessary to speed up the comprehensive improvement of the rural environment. By 2020, 130,000 new administrative villages have completed the comprehensive environmental imp...
