Technical Field

The invention relates to the technical field of sewage treatment, in particular to a filtering device for sewage treatment.

Background

Sewage refers to effluent from life and production that is contaminated to some extent. The water which loses the original use function is simply called sewage. Mainly is water after being used in life, contains more organic matters and is easy to treat. From the viewpoint of sewage source, sewage may be defined as waste-carrying liquid or water mixed with ground water, surface water, storm snow, etc., discharged from residential, institutional, commercial, or industrial areas. There are also many techniques and processes for the corresponding reduction of the environmental impact of sewage from many classes. Pressing the button

Of the water pollution caused by human production activities, the water pollution caused by industry is the most serious. Such as industrial waste water, which contains a large amount of pollutants and has complex components, is not easy to purify in water, and is difficult to treat. Industrial wastewater is the most important cause of water pollution caused by industrial pollution. It accounts for the majority of the industrially discharged pollutants. The pollutants contained in industrial wastewater are different from one plant to another, and even if the industrial wastewater is the same type of plant, the quality and the quantity of the pollutants contained in the industrial wastewater are different from one plant to another. In addition to pollution caused by direct injection of discharged wastewater into the water body, the solid waste and the waste gas also pollute the water body.

At present, sewage is required to be filtered in the sewage treatment process, but a plurality of larger wastes exist in the sewage, so that the problems of blockage and the like are often caused in the sewage filtration process, and more sewage still exists in the filtered sewage and wastes, so that further separation treatment is required.
