Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Such as figure 1 , figure 2 and Figure 4 As shown, the front view, top view and perspective view of the rural sewage treatment device of the present invention are provided respectively. The rural sewage treatment device shown is composed of a tank body 1, a first dividing plate 2, a second dividing plate 3, an inlet pipe 7, The water outlet pipe 8, the first inner cylinder 9, the first outer cylinder 10, the second inner cylinder 11, and the second outer cylinder 12 are composed. The tank body 1 is a horizontal cylinder or cuboid, and the inside of the tank body 1 is a cavity. Tank body 1 can adopt existing septic tank to transform. The first partition 2 and the second partition 3 divide the internal cavity of the tank body 1 into the first grid groove 4, the second grid groove 5 and the third grid groove 6 in sequence, and the second grid g...

Abstract

The invention relates to a rural sewage treatment device and method. Two partition plates in a tank body divide the tank body into a first grid groove, a second grid groove and a third grid groove, wherein the first grid groove is divided into a sedimentation tank, a first filtration tank and an anaerobic area; the second grid groove is divided into a first aerobic area; the third grid groove is divided into a second aerobic area, a phosphorus-removing tank and a second filtration tank; sewage settles firstly in the sedimentation tank and is filtered in the first filtration tank, and then theremoval of COD, ammonia nitrogen and organic phosphorus in sewage is realized by the first aerobic area; then, the sewage is subjected to deamination treatment in the anaerobic area, afterwards, the COD and a redundant carbon source are removed in the second aerobic area, phosphorus in the sewage is removed by the phosphorus-removing tank, finally, the sewage is filtered by the second filtration tank and then discharged, the successive settling, filtering, aerobic, anaerobic, aerobic, phosphorus-moving and filtering treatments of the sewage are realized, which guarantees that rural domestic sewage is connverted into a qualified water source and discharged, and the pollution and damage to surrounding soil environment and air environment are avoided.

Description

technical field [0001] The present invention relates to a rural sewage treatment device and method, more specifically, to a rural sewage treatment device which can successively carry out sedimentation, filtration, aerobic, anaerobic, aerobic, phosphorus removal and filtration treatment on sewage 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. The decentralized treatment mode of rural domestic sewage is an important part of rural water environment governance. The treatment of scattered sewage in rural areas or with small amounts of water must fo...
