Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an anti-clogging sewage treatment device. Background technique [0002] Sewage treatment refers to the process of treating sewage in order to make it discharge to a certain water body or reuse water quality. In modern life, especially with the deepening of urbanization, the living density of the population continues to increase, so the domestic wastewater and some other sewage in the population are also increasing. At the same time, in order to find more space in the existing living environment, urban construction is also increasingly developing towards high-rise buildings and underground buildings. But the problem of urban pollution, especially the problem of domestic sewage is also becoming more and more serious. [0003] Existing sewage treatment devices filter the sewage multiple times through filters or filter screens to remove impurities. [0004] When the existing sewage...
