Problems solved by technology
[0004] At present, the domestic coal chemical wastewater treatment method mainly adopts biochemical method. The biochemical method has a good effect on the removal of phenols and benzenes in wastewater, but it is difficult to remove some quinolines, indoles, pyridines, and carbazoles. The treatment effect of degraded organic matter is poor, making it difficult for the CODcr of the coal chemical industry to meet the first-class standard
[0005] In addition, the current manpower and material costs of coal chemical wastewater treatment are very high.
Due to the huge equipment, multiple workers need to work together, resulting in low production efficiency

Abstract
The invention relates to an automatic control system of coal chemical industry wastewater treatment equipment. The automatic control system comprises a control center and sensors and control valves which are controlled by the control center and separately arranged on an oil-water separation air flotation treatment device, an extraction device, a bioreactor, a nano micro-gas ozone treatment device, a reverse osmosis device and a follow-up treatment device, wherein a wastewater inlet pipe is connected with the oil-water separation air flotation treatment device; and a control valve opened / closed under the control of the control center is arranged on the wastewater inlet pipe. According to the automatic control system of coal chemical industry wastewater treatment equipment provided by the invention, automatic control of the treatment process can be realized, and the system is suitable for industrial implementation.
Description
technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to an automatic control system for coal chemical wastewater treatment equipment. Background technique [0002] The traditional coal chemical industry is an industry dominated by low-tech and low-value-added products with high energy consumption, high emissions, high pollution, and low efficiency, that is, "three highs and one low". This kind of excessive consumption of resources, serious pollution of the environment, extensive The unsustainable development pattern is unsustainable. For this reason, it is necessary to speed up the transformation of the development mode of coal chemical industry in due course and strive to promote the development of modern coal chemical industry. [0003] The wastewater discharged by coal chemical enterprises is mainly high-concentration gas washing wastewater, which contains a large amount of toxic and harmful substances such as phenol,...
