Rural sewage integrated treatment equipment and treatment process thereof

Abstract

The invention discloses rural sewage integrated treatment equipment and a treatment process thereof. The equipment comprises an integrated treatment tank, the internal space of the integrated treatment tank is divided into an anaerobic tank, an anoxic tank, an aerobic tank and a sedimentation tank through partition plates, openings are formed in the lower portion of the partition plate between theanaerobic tank and the anoxic tank and the upper portion of the partition plate between the anoxic tank and the aerobic tank, an MBBR filler is arranged in the aerobic tank, and an aeration mechanismis arranged at the bottom of the aerobic tank; and gas stripping conveying mechanisms are arranged between the aerobic tank and the anoxic tank, between the sedimentation tank and the anaerobic tank,and between the sedimentation tank and the sludge tank. The invention also provides the rural sewage integrated treatment process. According to the equipment, the anaerobic tank, the anoxic tank, theaerobic tank and the sedimentation tank are reasonably integrated, so the occupied area is small, mechanical equipment is few, only air blower equipment is adopted, sludge backflow is achieved in a gas stripping mode, the number of control points is small, energy consumption is low, the operation cost is low, the sludge backflow ratio is large, and microorganism loss is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an integrated treatment equipment for rural sewage and a treatment process thereof. Background technique [0002] Under the background of rapid social and economic development in our country, sewage treatment has been paid more and more attention, and rural sewage treatment has also been developed to a large extent. However, due to the characteristics of small drainage, dispersion, and relatively large water quality fluctuations in rural sewage, so There are still some problems in the process of rural sewage treatment. [0003] At present, in addition to the conventional traditional activated sludge method, the rural sewage treatment process has more applications such as constructed wetland, MBR integrated equipment, rapid infiltration land treatment system, oxidation pond technology, etc. Among them, the application of constructed wetland and MBR integrated ...

AI Technical Summary

Problems solved by technology

[0003] At present, in addition to the conventional traditional activated sludge method, the rural sewage treatment process has more applied technologies such as constructed wetland, MBR integrated equipment, rapid infiltration land treatment system, oxidation pond technology, etc. Among them, the application of constructed wetland and MBR integrated equipment More generally, although constructed wetlands have the characteristics of relatively small investment costs, low operating costs, low technical requirements for operation and maintenance, and can be constructed in combination with landscapes, they have the defects of large land occupation, low treatment efficiency, and are not easy to maintain and maintain. manage

MBR integrated equipment has good water quality and a high degree of automation. Due to high integration, it can save floor space, but it also brings inconvenience to later equipment maintenance, and the investment cost and operating cost are high.
