Description

A grease separator for sewage treatment

Technical Field

The utility model relates to the field of sewage treatment, and more specifically, to a grease separator for sewage treatment.

Background Art

Wastewater treatment: The process of purifying wastewater to meet the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical treatment, catering, etc., and is increasingly entering the daily lives of ordinary people.

For example, a grease three-phase separator disclosed in announcement number CN208980685U includes a vertically placed shell, a discharge port is provided at the bottom of the shell, the discharge port is connected to the inlet of a horizontally arranged screw conveyor, a discharge valve is provided at the discharge port, a filter screen is fixedly provided horizontally in the shell to separate the internal space of the shell into an upper chamber and a lower chamber, a raw material inlet is provided on the side wall of the lower chamber, a stop valve is provided at the raw material inlet, an exhaust port connected to an exhaust pipe is provided on one side of the top wall of the upper chamber, a grease discharge mechanism is provided on the other side of the top wall of the upper chamber, a nozzle for spraying washing liquid to the filter screen below is provided in the middle of the top wall of the upper chamber, and a plurality of exciters are evenly spaced along the circumferential direction in the middle of the outer wall of the shell corresponding to the filter screen. The advantages are that the structure is relatively simple, and the oil phase can be effectively separated, and the solid phase and the water phase can also be preliminarily separated; the feeding method is reasonable and the three-phase separation efficiency can be improved by standing still after the excitation.

It can be seen from the above-mentioned public scheme that the oil chamber and the water chamber inside the grease separator will be contaminated after long-term use, and dirt is easily attached to the inner wall of the chamber, which not only causes pollution to the oil chamber and the water chamber, but also causes pollution to the secondary oil-water separation. At the same time, most grease separators do not have the function of initial filtering and decontamination of oil and water liquids.
