If the sewage is not effectively treated and is directly discharged into the environment, serious harm is caused to the environment and human health. The garbage and suspended matters in the wastewater can affect the water surface landscape. Organic matters, nitrogen, phosphorus and other nutrient substances in the wastewater can cause water eutrophication, the concentration of dissolved oxygen in the water is reduced to be even zero, and aquatic animals and plants die. Heavy metals in wastewater can cause poisoning and even death of aquatic animals and plants, and if the heavy metals are absorbed by human bodies, the heavy metals can cause serious harm to human bodies. Persistent hazards can be formed for a long time by refractory organic matters in the wastewater in rivers and lakes or settled in bottom mud of rivers and lakes. Therefore, the sewage needs to be comprehensively and effectively treated, and can be discharged into the environment after reaching the national discharge standard, so that the harm of the sewage to the environment is reduced and even eliminated. Currently, solid-liquid separation devices used in sewage treatment processes still have some disadvantages. After the solid-liquid separation device works for a period of time, more and more sludge intercepted by the filter material in the solid-liquid separation device will be generated, so that the filter material is blocked, and the sewage treatment efficiency is influenced.
