Abstract

The invention discloses a sewage treatment agent for the printing and dyeing industry. The sewage treatment agent consists of the following raw materials in parts by weight: 16-20 parts of ethylenediaminetetraacetic acid disodium, 10-15 parts of sodium bicarbonate, 25-30 parts of sodium laurylsulfate, 22-25 parts of modified kieselguhr, 32-38 parts of polymeric aluminum, 14-16 parts of aluminum sulfate, 30-35 parts of medical stone, 23-25 parts of activated carbon, 10-14 parts of perlite, 8-13 parts of molybdenum sulfide, 14-17 parts of tin oxide powder and 22-27 parts of propylene glycol. The invention further provides a preparation method of the sewage treatment agent for the printing and dyeing industry. The sewage treatment agent disclosed by the invention can play a coordination function due to compounding of raw materials and has a very good treatment effect on sewage of the printing and dyeing industry, treated sewage can meet the national emission effect, the environment can be prevented from secondary pollution, and in addition, the treated sewage can also be recycled, so that the purpose of water resource conservation can be achieved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment agent used in the printing and dyeing industry and a preparation method thereof. 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. The printing and dyeing industry consumes a lot of water, usually 100-200t of water is consumed per ton of textiles f...
