[0002] The characteristics of food industry wastewater are high content of organic matter and suspended solids, easy to corrupt, and generally non-toxic. Its main harm is to cause eutrophication of water bodies, cause the death of aquatic animals and fish, cause the organic matter deposited at the bottom of the water to produce odor, deteriorate water quality, and pollute the environment.

[0003] The existing authorization announcement number is CN211562150U, which is a food wastewater treatment equipment, including a mounting base plate and a body arranged in the middle of the mounting base plate, slots are provided on both sides of the upper end of the body, plugs are inserted into the slots, the upper end of the plugs is fixedly connected to a top cover, the lower surface of the top cover is fixedly connected to a connection frame, the lower end of the connection frame is fixedly connected to a first filter screen, the lower surface of the first filter screen is fixedly connected to a filter screen cylinder at equal intervals, a second filter screen is fixedly connected between the upper ends of the body, and the second filter screen is located at the lower end of the filter screen cylinder. The equipment has a more reasonable structure and a more optimized design, and can perform multiple filtrations on solid impurities contained in food wastewater, which is convenient for cleaning solid impurities in the filter screen, and can also introduce the generated precipitate into the sedimentation chamber, so that the precipitate is separated from the wastewater, which is convenient for the discharge of the wastewater.

[0004] However, it still has the following defects: the device can effectively filter wastewater through triple filtration, but when cleaning is needed, it is necessary to remove the top cover to clean the first filter, the filter cylinder and the second filter, but because the three are still connected to the top cover, after removing the top cover, the three need to be removed and cleaned one by one, the use process is inevitably complicated, and the self-cleaning of the filter cannot be achieved, and the use effect still needs to be improved.
