Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a multi-layer filter for water environment pollution. Background Art

[0002] Water pollution is caused by harmful chemicals that reduce or lose the use value of water and pollute the environment. Acids, alkalis, oxidants, compounds such as copper, cadmium, mercury, arsenic, and organic toxins such as benzene, ethylene dichloride, and ethylene glycol in sewage can poison aquatic organisms and affect drinking water sources and scenic spots. When organic matter in sewage is decomposed by microorganisms, it consumes oxygen in the water, affecting the life of aquatic organisms. After the dissolved oxygen in the water is exhausted, the organic matter undergoes anaerobically decomposition, producing unpleasant gases such as hydrogen sulfide and mercaptans, which further deteriorate the water quality.

[0003] When conducting water pollution control, it is necessary to use filters to filter sewage. When most filters are used, a filter net is needed to perform preliminary filtration of impurity particles in the sewage. In order to prevent the impurity particles after filtration from accumulating on the filter net and causing the filter net to be blocked, the staff is required to stop sewage filtration frequently and clean the filter net. This operation is not only time-consuming and labor-intensive, but also reduces the filtration efficiency. Utility Model Content
