摘要
Abstract
The characteristic of China's energy structure is that there is more coal and less oil.Coal chemical industry is an important way to achieve clean and efficient utilization of coal,and the effective treatment of coking wastewater is related to the sustainable development of the coal chemical industry.During the production process,a large amount of difficult to degrade substances such as industrial raw materials and by-products enter the wastewater,and coking wastewater has characteristics such as complex composition,high toxicity,poor biodegradability,and strong carcinogenicity.Coking enterprises usually adopt a three-stage or four-stage combined treatment process of pre-treatment,biochemical treatment,deep treatment,and reuse treatment,after traditional biochemical treatment,the chemical oxygen demand(COD)and chromaticity of the effluent still cannot meet the requirements of the"Emission Standards for Pollutants in the Chemical Industry of Coking"(GB 16171-2012).Based on the sources and characteristics of coking wastewater,this paper reviews the traditional and innovative models of coking wastewater treatment,and looks forward to future development directions,so as to achieve economic and efficient coking wastewater treatment.关键词
