Description

A filter device for water pollution control

technical field

The utility model relates to the technical field of water treatment equipment, in particular to a filter device for water pollution control.

Background technique

Among the water pollution caused by human production activities, the water pollution caused by industry is the most serious. For example, industrial wastewater contains many pollutants and complex components. It is not only difficult to purify in water, but also difficult to treat. According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, etc., while domestic sewage is sewage produced in daily life, which refers to a complex mixture of various forms of inorganic and organic substances, including: ①floating and suspended solid particles of large and small sizes; ②glue Shape and gel-like diffuser; ③ pure solution. Direct discharge of sewage will cause environmental damage. At present, in order to treat sewage, sewage treatment plants have been built in many places. However, sewage treatment plants occupy a large area and are expensive, so they are not suitable for small-scale water purification. However, the filter devices used in some small sewage treatment equipment are easily blocked, resulting in reduced filtration efficiency. It is very inconvenient to clean the filter core frequently during use.
