Oily sewage treatment apparatus

Abstract

The invention discloses an oily sewage treatment apparatus. The apparatus comprises an oil removal device, a control box, power distribution boxes, a ventilating port, a water tube and a water outlet,the water outlet is embedded in the right side of the oil removal device, the back of the control box is fixedly mounted in the front of the oil removal device, the bottom surfaces of the power distribution boxes are fixedly welded to the top of the oil removal device, and the power distribution boxes are located at the left side of the ventilating port. When the sewage treatment apparatus is used to collect oil, air is introduced into water in a micro-bubble form under the action of an air flotation device, the micro-bubbles adhere to suspended oil in the water to form a water-gas-oil three-phase mixed system, adhesion of the bubbles to the oil makes the oil have a smaller density than water and float on the water level in order to a floating residue layer, the floating residue layer isseparated from the water, and the oil is collected into a collecting tank under the action of a wall scraper mechanism; and an acid removal agent and an electrolysis layer are also adopted during sewage treatment to achieve auxiliary effects in order to convert treated sewage into usable water.

Description

technical field [0001] The invention relates to the field of wastewater treatment equipment, in particular to a grease-based sewage treatment device. Background technique [0002] In rural sewage treatment, most of the sewage contains grease, jelly and suspended solids, and there are a lot of impurities in the sewage. According to different foods: meat products, vegetables, beverages, starch, brewed products, etc., Containing grease, jelly is also different. [0003] In the treatment of sewage, because grease is a kind of insoluble pollutant, and it is difficult to completely recycle the grease in the equipment recovery process, the residual grease may stick in some gaps, which will affect the downstream One-step sewage treatment will also make it difficult to remove the odor of sewage. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies in the prior art, the present invention provides a grease-based sewage treatment devi...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a grease-based sewage treatment device to solve the problem that grease is a difficult-to-melt pollutant in the treatment of sewage, and the recovery process of the equipment is very difficult. It is difficult to completely recycle, resulting in the residual grease may stick to some gaps, which will affect the next step of sewage treatment, and also make it difficult to remove the odor of sewage
