Wastewater treatment equipment capable of realizing sequential dosing and working method of wastewater treatment equipment

Abstract

The invention discloses wastewater treatment equipment capable of achieving sequential dosing and a working method of the wastewater treatment equipment, and particularly relates to the technical field of sewage treatment. The wastewater treatment equipment comprises an equipment base, wherein an equipment rack is fixedly arranged at the top of the equipment base, a first chemical dosing treatment tank, a second chemical dosing treatment tank and a third chemical dosing treatment tank are sequentially and fixedly arranged in the equipment rack from left to right, fixing frames are fixedly arranged on the inner walls of the middles of the first chemical dosing treatment tank, the second chemical dosing treatment tank and the third chemical dosing treatment tank, and wastewater inlet pipes are fixedly arranged at the bottom of the first dosing treatment tank, the second dosing treatment tank and the third dosing treatment tank. The first dosing treatment tank, the second dosing treatment tank and the third dosing treatment tank are matched with the wastewater inlet pipe and the connecting pipe to form a wastewater treatment system, dosing is implemented by using the dosing inlet pipe, three times of continuous wastewater dosing treatment operation on wastewater is realized, and a stirring rod on a rotating shaft stirs and mixes wastes and drugs, so that the drug reaction treatment quality is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a waste water treatment equipment and a working method for realizing sequential dosing. Background technique [0002] Water is one of the essential resources in human life. With the use of people, cities will produce a large amount of wastewater, which will affect the quality of human life and water quality, so the treatment of wastewater is more important. Wastewater treatment is the use of physical, Chemical and biological methods are used to treat wastewater to purify wastewater and reduce pollution, so as to achieve the role of wastewater recycling and reuse. The main sources of water pollution are domestic sewage and industrial wastewater, of which industrial wastewater bears the brunt, and flue gas desulfurization wastewater It is also one of the key industrial waste waters fueled by coal or coal coke, which is harmful to human body and environment. my country is ...

AI Technical Summary

Problems solved by technology

[0004] To this end, the embodiment of the present invention provides a wastewater treatment device and its working method that realizes sequential dosing, through the first dosing treatment tank, the second dosing treatment tank and the third dosing treatment tank, cooperate with the waste water inlet pipe and the connecting pipe to form waste water The treatment system uses the dosing pipe to implement dosing, realizes three continuous waste water dosing treatment operations, and the agitating rod on the rotating shaft stirs and mixes the waste and medicine to improve the quality of medicine reaction treatment, so as to solve the problem of waste water in the prior art. There are many types of waste in the system, and the effect of one-time drug delivery on waste treatment is not ideal, and the problem caused by poor wastewater treatment quality
