Abstract

The invention discloses a preparation method of an industrial water drainage treatment agent. A variety of biological materials are treated and mixed with other additives for the preparation of industrial water drainage treatment agent. The method is simple for operation; and the prepared industrial water drainage treatment agent has low cost and good effect, and is suitable for mass production. The industrial water drainage treatment agent prepared by the method has the removal rate of the suspended matters in industrial drainage water of up to 90% or more, the BOD removal rate of above 90%, and the COD removal rate of above 90%.

Description

technical field [0001] The invention relates to the technical field of industrial wastewater treatment, in particular to a preparation method of an industrial wastewater treatment agent. Background technique [0002] Industrial wastewater refers to the wastewater, sewage and waste liquid produced in the process of industrial production, which contains industrial production materials, intermediate products and products lost with water, as well as pollutants produced in the production process. With the rapid development of industry, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly widespread and serious, threatening human health and safety. Therefore, for the protection of the environment, the treatment of industrial wastewater is more important than the treatment of urban sewage. At present, industrial wastewater treatment agents mainly include aluminum sulfate, ferric sulfate, ferric chloride, titanium ...
