Coal chemical industry wastewater treatment system

Abstract

The invention belongs to the technical field of wastewater treatment, and concretely relates to a coal chemical industry wastewater treatment system. The system comprises a cylindrical shell, a waterinlet tube, a water outlet tube, an oil outlet tube and a suction separation module; the suction separation module comprises a motor, a rotating block, a fixed disc, pipettes and a gas suction tube; the motor is mounted on the top of the cylindrical shell, and the end of the output shaft of the motor is fixedly connected with the rotating block; the rotating block is provided with a square groovepenetrating through the upper surface and the lower surface of the rotating block, the rotating block is rotatably mounted in the fixed disc, the fixed disc is fixedly connected with the inner wall ofthe cylindrical shell, and the bottom of the fixed disc is fixedly connected with a group of the pipettes; a non-return valve is arranged at the upper end of every pipette, and the top of the fixed disc is fixedly connected with the gas suction tube; the gas suction tube is used for generating a negative pressure in the square groove; and the negative pressure is generated in the square groove, and oil on the surface of wastewater is sucked into the square groove through the pipettes, and then is intensively discharged. A suction way is adopted to avoid high wastewater content of the oil, caused by waves generated by sloshing of the wastewater, so the precision of oil separation is improved.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, in particular to a coal chemical wastewater treatment system. Background technique [0002] Coal chemical industry is a comprehensive industrial process in which mined coal is used as raw material and transformed into various fuels and chemicals through a series of chemical and chemical processes. As one of the traditional industries, the characteristics of high energy consumption, high emission and low efficiency of coal chemical industry have always restricted the development of this industry. Although the introduction of new green coal chemical technology has improved the pollution situation in recent years, the serious environmental pollution caused by the coal chemical industry still cannot be effectively solved. Among them, wastewater discharge has the most serious impact on the environment. Coal chemical industry wastewater is a typical organic industrial wastewater that is ...

Problems solved by technology

[0005] This technical scheme can realize the automatic separation of oil, but when the oil is separated, the scheme uses a scraper to separate the oil. When the scraper scrapes off the oil on the surface of the wastewater, it will cause waves on the liquid surface, resulting in The excess waste water and oil are separated together, so that the separated oil contains a large amount of waste water, and its separation accuracy is low
