[0002] Power plants generate a large amount of wastewater and sludge during the power generation process. The main sources of sludge include sediments in the wastewater treatment process, gypsum slurry produced by the desulfurization system, ash produced by boiler soot blowing and cleaning, etc. When pre-treating the wastewater and sludge, it is necessary to filter the larger impurities through the filter. After a long period of treatment, the filter is often blocked by impurities, resulting in poor filtering effect. At the same time, impurities such as sludge deposited at the bottom of the treatment box may condense after a long period of accumulation, causing inconvenience when discharged from the treatment box.
