Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to an integrated sewage treatment purification tank. Background Art

[0002] Suitable for treating single-household domestic sewage in remote rural areas of the high-altitude and cold regions of Northeast China. Currently, remote areas have scattered sewage discharge points, small sewage volumes, and difficulty in collecting and constructing pipe networks. Sewage cannot be fed into urban sewage pipe networks, so the only option is to build a nearby sewage treatment station. However, the construction of a pipe-based sewage station is difficult and the investment cost is high. This is when purification tanks are needed.

[0003] The purification tanks currently on the market have the following problems when used:

[0004] 1. Traditional purification tanks require a high level of purification technology, which makes purification difficult and requires a large investment. In addition, it is difficult to filter the sewage multiple times inside, making it difficult to meet sewage treatment standards and resulting in poor purification quality.

[0005] 2. Traditional purification tanks are made of non-metallic products such as fiberglass and PVC. The climate in the high-altitude cold regions of Northeast China and the pressure conditions at the same location under the soil are different in the four seasons. Sewage treatment tanks made of fiberglass and PVC materials are prone to deformation or leakage in winter and spring, which makes operation inconvenient. Utility Model Content
