我国水资源条件先天不足,煤炭资源与水资源呈逆向分布,其特点是多煤的地方缺水,多水的地方缺煤。在煤炭资源丰富地区发展煤化工产业,必须正视水资源条件,解决好煤化工产业发展用水与农业用水、生态用水和其它工业用水的关系。现代煤化工产业的显著特点是生产规模大,相应地耗水量大、废水产生量大、水质复杂、污染物浓度大、处理难度大。多年来,我国煤化工废水处理技术工艺研究和应用水平已取得良
In our country, the water resources conditions are inherently inadequate. The coal resources and water resources are in reverse distribution, which is characterized by lack of water and water shortage in many coal-bearing areas. In coal resources rich areas to develop coal chemical industry, we must face water resources conditions, to solve the development of coal chemical industry and agricultural water use, ecological water and other industrial water relations. The remarkable feature of the modern coal chemical industry is the large scale of production, correspondingly large amount of water consumption, large amount of wastewater generated, complex water quality, large pollutant concentration, and great difficulty in handling. Over the years, China’s coal chemical wastewater treatment technology research and application of the level has been made good
