technical field

The utility model relates to the technical field of sewage treatment equipment, in particular to an integrated purification system for grease impurities and sewage.

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. Sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, while domestic sewage is the sewage produced in daily life, which refers to the complex mixture of various forms of inorganic and organic substances.

Sewage contains a wide variety of substances, including floating and suspended solid particles of large and small sizes, colloidal and gel-like spreads, grease, and heavy silt and metal particles. If these particles and rubbish are not cleaned up in time, the sewage treatment equipment will be blocked quickly, requiring parking for cleaning, seriously affecting the normal operation of production and causing huge losses to the system. In addition, the oil in the sewage can be recycled as chemical raw materials to produce high-grade chemical products.

In recent years, with the development of science and technology and interdisciplinary comprehensive utilization, there have been many studies on sewage treatment at home and abroad, and many techniques for sewage treatment have been reported. At present, most of the devices used for sewage treatment at home and abroad are independent The way of treating sewage, and most of these devices have the disadvantages of complicated process, large floor space, and high price.
