technical field

The invention belongs to the technical field of sewage treatment equipment, and in particular relates to a high-efficiency sewage filtering device.

Background technique

Sewage treatment is the process of purifying sewage to meet the water quality requirements for reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. The progress and development of modern society are inseparable from water resources. 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 the sewage generated in daily life, which refers to the complex mixture of various forms of inorganic and organic substances.

At present, the sources of sewage water in the sewage treatment center are very complicated, and the water quality is various. The sewage includes floating and suspended solid particles of large and small sizes, colloidal and gel-like diffusers, and sediment and metal particles with large specific gravity. . If these particles and garbage are not cleaned up in time, the sewage treatment equipment will be blocked quickly, such as the lifting pump, feeding pump, heater, anaerobic reactor inlet pipe, etc. will be blocked, and it will be necessary to stop for cleaning, which will seriously affect production Normal operation, causing huge losses to the system. Therefore, it is necessary to install a filter device to clean up the garbage in the sewage, so as to ensure the normal operation of sewage treatment and production.
