Example Embodiment

[0029] Specific embodiment one

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

Example Embodiment

[0049] Specific embodiment two

[0050] The difference between this embodiment and the first embodiment is that the anaerobic hydrolysis tank 23 is not provided, the water inlet pipe 1 is directly connected to the inlet of the anaerobic tank 21, the anaerobic tank 21 and the anoxic tank 22 are not provided with folding plates 24, The anaerobic tank 21 and the anoxic tank 22 are equipped with agitators, and the rest of the structure is the same as in the first embodiment.

[0051] The method for treating sewage using the integrated sewage treatment device described above is different from the first embodiment in that the sewage is transported to the water inlet pipe 1, and driven by the water flow, it flows into the anaerobic tank 21, anoxic tank 22 and In the aerobic tank 3, in the anaerobic tank 21 and the anoxic tank 22, the agitator stirs the sewage therein, and the remaining explanations are the same as in the first embodiment.

[0052] The quality of the sewage effluent treated...

Example Embodiment

[0053] Specific embodiment three

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

[0055] The method for treating sewage using the integrated sewage treatment device described above is different from the first embodiment in that the sewage is transported to the water inlet pipe 1, and driven by the water flow, flows into the anaerobic hydrolysis tank 23 and the anoxic tank 22 in sequence. And the aerobic tank 3, a part of the sludge in the sludge storage tank 5 flows back to the anoxic tank 22 through the sludge return pipe 12 and the sludge return pump 11, a...

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...
