Coal chemical industry wastewater treatment device

Abstract

The invention discloses a coal chemical wastewater treatment device, which comprises a pretreatment box, a feed hopper is arranged at the upper port of the pretreatment box, a feeding pipe is arranged at the lower end of the feeding hopper, and the inside of the pretreatment box below the feeding pipe is There is a conical filter screen, the lower end of the conical filter screen is in contact with the inner wall of the pretreatment box, and there are several discharge ports on the pretreatment box where the lower end of the conical filter screen is located, and the pretreatment box outside the discharge port is fixed with a collection Enclosure, a detection tube is fixed in the middle of the lower end of the pretreatment box, and a pH detector and a flow meter are arranged on the outside of the detection tube. The structure of the invention is simple and reasonable, and the material can be guided during pretreatment, thereby facilitating the removal of impurities. At the same time, the rotary spraying treatment is used during neutralization, so that the two raw materials can be mixed quickly, which helps to increase the neutralization speed, thereby keeping the sewage neutral, which is helpful for the later membrane filtration treatment, and is practical powerful.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a coal chemical wastewater treatment device. Background technique [0002] Environmental pollution brought about by economic development is becoming more and more serious, and environmental protection has increasingly become the focus of today's era, and environmental protection water treatment is a very critical part of it. Environmental water treatment focuses on the treatment of high-concentration industrial wastewater. Coal chemical industry is a clean and efficient coal utilization method, but a large amount of highly polluted coal gasification wastewater is produced during the coal gasification process. The composition of the wastewater is developed, and there are many types of refractory organic matter. It is one of the most difficult and harmful industrial wastewater. Coal chemical industry wastewater is mainly gas-washed wastewater, which contains a large a...
