[0002] Papermaking industry wastewater contains a large amount of suspended fiber, lignin, organic matter and nitrogen, phosphorus and potassium compounds. Direct discharge will reduce the transparency of water, cause the water color to turn black, and cause eutrophication, which is extremely harmful to the environment. The water volume and water quality are mainly adjusted through grids, screens and fiber recovery systems to improve the sewage quality and achieve the best treatment effect of the entire sewage treatment system.

The process mainly involves the fibers in the wastewater itself and the precipitates formed after adding flocculants. When using grids, screens and other structures to filter wastewater, there is often a problem of clogging the filter holes. Common technologies use manual or mechanical structures to clean the surface of the filter element. Because the cleaning of impurities is in different steps, it is necessary to set up multiple cleaning positions.
