Sewage treatment device

Abstract

The invention is suitable for the technical field of sewage treatment equipment, and provides a sewage treatment device which comprises a cylinder body, the interior of the cylinder body is divided into a plurality of cavities for treating sewage through partition plates, and the multiple cavities are communicated through connecting channels. A filtering device for filtering sludge in the cavity is arranged outside the cylinder body. The filtering device comprises a sewage suction head mounted in the cavity, the sewage suction head penetrates through the cylinder body and extends to the outside to be connected with a filter box, the filter box is communicated with the cavity through a jet pipe, and a filter is mounted in the filter box. By adopting the technical scheme, sludge in sewage can be filtered when the sewage is treated, the problem of blockage of the sewage treatment device is avoided, an oxygen pump of an aerobic tank is omitted by the jet pipe, the aerobic tank is directly inflated, the filter can be self-cleaned, manpower is omitted, and the whole filtering device is simple in structure, low in production cost and high in practicability.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a sewage treatment device. Background technique [0002] In recent years, through the continuous advancement of the construction of beautiful villages, the number of new construction, reconstruction and expansion of rural sewage treatment equipment in some areas of my country has increased significantly, and the level of construction and management has also been improved to a certain extent. The "three difficulties" problem has not been completely solved in some areas; there are still many problems in the construction and management of rural sewage treatment in many areas, for example: the scientific design of buildings is poor, and the design of manure treatment cannot be adapted to local conditions; the management level is lagging behind, Dilapidated appearance, damaged internal equipment, piles of garbage, cross-flow of sewage, flying mosquitoes and flies, pun...

Problems solved by technology

[0002] In recent years, through the continuous advancement of the construction of beautiful villages, the number of new construction, reconstruction and expansion of rural sewage treatment equipment in some areas of my country has increased significantly, and the level of construction and management has also been improved to a certain extent. The "three difficulties" problem has not been completely solved in some areas; there are still many problems in the construction and management of rural sewage treatment in many areas, for example: the scientific design of buildings is poor, and the design of manure treatment cannot be adapted to local conditions; the management level is lagging behind, Dilapidated appearance, damaged internal equipment, piles of garbage, cross-flow of sewage, flying mosquitoes and flies, pungent smell, poor overall sanitation, etc. In the face of these problems, it is urgent to use standardized means to standardize the construction, management and service of sewage treatment in rural areas of our country and maintenance

[0003] However, the three-compartment septic tank model commonly used in the process of rural sewage treatment still has secondary pollution caused by the inability of feces to be effectively decomposed; regular excrement pumping is required; urinals need to be connected to tap water; and affected by cold weather, The flushing water tank is easy to freeze and cannot be used, and the existing septic tank cannot treat domestic sewage such as laundry and cooking.

[0004] In the process of sewage treatment, because the sludge in the sewage can easily cause the blockage of the sewage treatment device, it needs to be dredged artificially, which is not only difficult, but also contains a lot of bacteria in the sewage, which is not healthy for people

[0005] For example, the equipment disclosed in the application number CN201922334869.0 can only perform one cycle of purification, and the purified water is difficult to meet the standard, and in the process of use, it is easy to cause sludge blockage, which needs to be cleaned manually

[0006] In the process of sewage treatment, it is necessary to add an oxygen pump to a specific reaction tank to carry out oxygenation treatment, and the cost of use is too high

[0007] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
