Description

technical field [0001] The invention relates to industrial wastewater treatment, in particular to a method and device for treating coal-containing wastewater with multifunctional combination. Background technique [0002] With the development of human society and economic progress, the country attaches great importance to environmental issues and invests more and more in environmental protection. At this stage, my country's requirements and standards for pollution emission control have become higher and higher. [0003] The main characteristics of coal-containing wastewater are high concentration of suspended solids, small particle size, light specific gravity, and the particles have a strong negative charge, which has the characteristics of a colloidal dispersion system, so it is difficult to settle naturally. If such waste water is discharged directly, it may lead to blockage of drainage system pipes, affect environmental pollution inside and outside the factory area, and ...
