Full-automatic grease impurity separation device for sanitary sewage

Abstract

The invention discloses a full-automatic grease impurity separation device for sanitary sewage. The full-automatic grease impurity separation device comprises a sanitary sewage inlet, a solid interceptor and two liquid level sensors, wherein the solid interceptor is connected with the sanitary sewage inlet and an isolation tank, sewage is adequately settled in the isolation tank and flows into anauxiliary isolation tank connected with the isolation tank, an auxiliary pump is connected to an outlet of the auxiliary isolation tank and is used for guiding sewage into the solid interceptor for secondary separation, grease is separated from the sewage and flows into a sanitary sewage pipeline through an outlet, and aeration chambers are arranged in the isolation tank and the auxiliary isolation tank; and the two liquid level sensors are used for detecting the liquid levels of the grease in the isolation tank and the auxiliary isolation tank and discharging the accumulated grease at properliquid levels.

Description

technical field [0001] The invention relates to domestic sewage treatment, in particular to a fully automatic device for separating grease and impurities in domestic sewage. Background technique [0002] Grease and impurity separators are commonly used in restaurants, meat and poultry processing plants, slaughterhouses and other industries that have excess grease wastewater and impurities (such as insoluble solids), and the grease in the sewage must be treated to prevent it from being discharged into the sewer system. In many urban communities in our country, urban sewage treatment facilities are often overwhelmed, and the harmful "gutter oil" used by unscrupulous businesses is usually extracted from domestic sewage. Therefore, it is very necessary to strengthen the treatment of urban sewage. [0003] In recent years, with the development of science and technology in our country, more and more attention has been paid to sewage treatment in China. There are many related res...

Problems solved by technology

[0003] In recent years, with the development of science and technology in our country, more and more attention has been paid to sewage treatment in China. There are many related researches and sewage treatment equipment. Circulating Grease and Miscellaneous Separation Device", and the Chinese patent authorization announcement number is CN201669005U, and the name is the disclosed structure of "New Catering Slag, Water, Oil Separation Swill Bucket Machine". The disadvantage of the above-mentioned equipment structure is: due to the The oil and sewage can easily become emulsified oil and water. It is difficult to effectively reduce the oil content in the sewage after only one treatment. There is no sewage secondary treatment device, and the oil content in the sewage cannot be effectively reduced.
