specific Embodiment approach 1

[0030] An integrated sewage treatment device suitable for rural sewage, including a water inlet pipe 1, an anaerobic biochemical unit 2, an aerobic pool 3, a mud-water separation pool 4, a mud storage pool 5, a disinfection pool 6, an outlet pipe 7, and a coagulation pool 8. The reaction tank 9 and the sedimentation tank 10 are connected in series in sequence along the flow direction of the sewage, the water inlet pipe 1, the anaerobic biochemical unit 2, the aerobic tank 3 and the mud-water separation tank 4, and the mud at the bottom of the mud-water separation tank 4 The area is communicated with the mud storage tank 5 through the mud hole 14, and the upper water area of ​​the mud-water separation tank 4 is communicated with the coagulation tank 8, and the coagulation tank 8, the reaction tank 9, the sedimentation tank 10 and the disinfection tank 6 are connected in series in sequence In communication, the disinfection tank 6 is in communication with the water outlet pipe 7 ...

specific Embodiment approach 2

[0050] The difference between the present embodiment and the specific embodiment one is: the anaerobic hydrolysis tank 23 is not provided, the water inlet pipe 1 is directly communicated with the entrance of the anaerobic tank 21, and the folding plate 24 is not set in the anaerobic tank 21 and the anoxic tank 22. Agitators are arranged in the anaerobic pool 21 and the anoxic pool 22, and the rest of the structures are the same as in the first embodiment.

[0051] The method of using the above-mentioned integrated sewage treatment device to treat sewage is different from the specific embodiment 1 in that: the sewage is transported to the water inlet pipe 1, and under the impetus of the influent water flow, it flows into the anaerobic pool 21, anoxic pool 22 and In the aerobic pool 3, in the anaerobic pool 21 and the anoxic pool 22, the mixer stirs the sewage therein, and the rest of the explanations are the same as those in the first embodiment.

[0052] The effluent water qua...

specific Embodiment approach 3

[0054] The difference between this embodiment and specific embodiment 1 is that no anaerobic pool 21 is provided, and the water inlet pipe 1, the anaerobic hydrolysis pool 23, the anoxic pool 22 and the aerobic pool 3 are sequentially connected in series along the flow direction of the sewage. The sludge storage tank 5 communicates with the anoxic tank 22 through the sludge return pump 11 and the sludge return pipe 12, and the rest of the structures are the same as the first embodiment.

[0055] The method of using the above-mentioned integrated sewage treatment device to treat sewage is different from the specific embodiment 1 in that the sewage is transported to the water inlet pipe 1, and under the impetus of the influent water flow, it flows into the anaerobic hydrolysis tank 23 and the anoxic tank 22 in sequence. And the aerobic tank 3, a part of sludge in the sludge storage tank 5 returns to the anoxic tank 22 through the sludge return pipe 12 and the sludge return pump 1...

Abstract

The invention discloses an integrated sewage treatment device suitable for rural sewage and belongs to the technical field of sewage treatment. The device comprises a water inlet pipe, an anaerobic biochemical unit, an aerobic tank, a mud-water separation tank, a mud storage tank, a coagulation tank, a reaction tank, a sedimentation tank, a disinfection tank and a water outlet pipe, flow directionof sewage, wherein the water inlet pipe, the anaerobic biochemical unit, the aerobic tank and the sludge-water separation tank are sequentially communicated in series, a lower sludge area of the sludge-water separation tank is communicated with the sludge storage tank, an upper water area of the sludge-water separation tank is communicated with the coagulation tank, the coagulation tank, the reaction tank, the sedimentation tank and the disinfection tank are sequentially communicated in series, and the disinfection tank is communicated with the water outlet pipe. The sewage treated by the device provided by the invention can ensure that the effluent quality meets the discharge standard of the first grade A of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002).

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an integrated sewage treatment device suitable for rural sewage. Background technique [0002] Today, my country's rural areas have undergone earth-shaking changes in economic and social development, and the material living standards of the people have been significantly improved. However, due to the extensive concept of rural development and weak awareness of environmental protection in the past, rural sewage has not been properly treated, resulting in increasingly serious water pollution, which not only endangers the ecological environment, but also threatens human health, which is not in line with the concept of sustainable development. Therefore, , the problem of rural sewage treatment needs to be solved urgently. [0003] At present, most rural sewage treatment facilities copy the urban sewage treatment model, blindly choosing treatment facilities and s...
