Oil removal and skimming device for sewage treatment and oil removal method

Abstract

The invention discloses an oil removal and skimming device for sewage treatment and an oil removal method.The oil removal and skimming device comprises a salvage pond, a treatment pond, a gate, a chemical feeding frame and a mixing motor, two cavities are formed in the treatment pond and are the chemical feeding cavity and the sedimentation cavity respectively, and the chemical feeding cavity and the sedimentation cavity are in an inclined state relative to the treatment pond; the gate is arranged between the sedimentation cavity and the medicine feeding cavity, the salvage pool is communicated with the treatment pool through a pipeline, and a sewage draining exit is formed in the upper portion of the salvage pool. Compared with the prior art, the equipment has the beneficial effects that the equipment for precipitating the oil layer by using the chemical medicine is provided by the technical scheme, oil is filtered after being precipitated by the equipment, the filtering effect can be greatly improved, and automatic fishing equipment is adopted by the technical scheme to realize rapid fishing, so that the equipment is convenient to use. And a multi-section integrated type inner cavity filtering system is adopted, sundries of different degrees can be filtered in a concentrated mode, then the sundries are taken out in a vibration mode and concentrated in one container, and the sundries can be conveniently taken out manually.

Description

technical field [0001] The invention relates to the field, in particular to an oil removal and scum removal device and an oil removal method for sewage treatment. Background technique [0002] In order to make the sewage meet the discharge standard or meet the water quality requirements for reuse, sewage treatment is carried out on the sewage. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering. More and more into the daily life of ordinary people. [0003] In the prior art, the treatment of oily sewage generally includes two processes: skimming and deoiling. Skimming is to remove bulk impurities and granular impurities in sewage, and deoiling is to remove oil and other substances floating on the upper layer of sewage; [0004] First, the equipment currently on the market mainly uses the method of filtering the oil layer to remov...

AI Technical Summary

Problems solved by technology

[0004] First, the equipment currently on the market mainly uses the method of filtering the oil layer to remove it. Due to the high density of the filtering equipment, the oil treatment is not clean. Second, the sundries inside the sewage are mainly processed by salvage. , and because larger debris can be removed during salvage, the treatment is not clean. Third, the relatively high-end equipment now adopts a tubular structure for removing impurities, and when the internal debris is full, manual cleaning is required. It is relatively troublesome to remove
