Description

Technical Field

[0001] The utility model relates to the field of sewage purification, and more specifically, to an in-situ purification device for pollutants. Background Art

[0002] During the urban construction process, the land was hardened and the water source was isolated, resulting in a large amount of rainwater being unable to penetrate into the ground, forming a large amount of stagnant floodwater. Because these stagnant floodwaters cannot penetrate, they flow directly into the sewers, and the rivers carry away the pollutants accumulated in the closed urban environment, causing pollution of the initial rainwater runoff.

[0003] At present, the general way to deal with such pollutants is to set up screens at the sewage collection point to filter out debris in the water. However, it is difficult to effectively purify pollutants and harmful substances, and they will still cause pollution to the river water. Utility Model Content

[0011] As a further description of the above technical solution: the membrane filter is a MBAR membrane reactor.

[0012] Compared with the prior art, the advantages of the present invention are:
