Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically, to a filter for sewage treatment. Background Art

[0002] Sewage treatment filters are a type of equipment specifically used to treat sewage. Their main purpose is to remove impurities and harmful substances from sewage so that the sewage can be reused or discharged. These filters are widely used in urban sewage treatment, industrial wastewater treatment, farmland irrigation water treatment, and household sewage treatment.

[0003] In the existing sewage treatment process, the filter, as a key equipment, mainly relies on the filter inside it to achieve solid-liquid separation. Specifically, when sewage flows through the filter, solid impurity particles are intercepted, but a certain amount of sewage is usually attached to the surface of these particles. These sewage attached to the impurity particles are not easy to be completely removed through a simple filtration process due to the adhesion or surface tension between the particles. As the filtration time increases, these residual sewage will gradually accumulate, which not only increases the burden on the filter, but also may cause the filter to be blocked and affect the filtration efficiency. What is more serious is that the harmful substances in these attached sewage that have not been effectively removed, such as heavy metals, organic matter, etc., may be released back into the water as the filtration process proceeds, resulting in a decrease in the purification effect. This not only affects the quality of the final treated water, but may also cause secondary pollution to the environment. Utility Model Content
