[0002] Sewage refers to the discharged water from life and production that is polluted to a certain extent. Water that has lost its original use function is simply called sewage, while suspended matter refers to solid matter suspended in water, including inorganic and organic matter that are insoluble in water, mud, clay, microorganisms, etc.

[0003] Existing solid suspended matter crushing devices for sewage treatment generally directly pour sewage into the treatment box and then directly crush the garbage inside it, rather than separating the sewage from the solid suspended matter and then crushing the solid suspended matter. This causes the crushed small particles of solid suspended matter to mix with the sewage, which can easily clog the filter screen and affect the filtering effect. Therefore, we need to propose a solid suspended matter crushing device for sewage treatment. Utility Model Content
