Abstract

The invention discloses an industrial dyeing sewage treatment agent and a preparation method thereof. The treatment agent is prepared from following components in mass percent: 25-35% of polyaluminum chloride, 10-12% of lime, 12-18% of grain starch, 9-11% of kaolinite, 4-6% of graphene, 10-12% of palygorskite, 14-16% of kieselguhr, 0.8-1.2% of potassium permanganate and 1.5-2.5% of bleaching powder; the preparation method comprises the following steps: respectively smashing lime, kaolinite, palygorskite and kieselguhr into powder, mixing, and fully and uniformly stirring, adding potassium permanganate, fully mixing, finally, sequentially adding polyaluminum chloride, grain starch, graphene, and bleaching powder, uniformly mixing, smashing, carrying out microwave treatment, bagging and sealing, so as to obtain the industrial dyeing sewage treatment agent. The industrial dyeing sewage treatment agent disclosed by the invention has a high agglomeration effect on organic pollutants and impurities in the dyeing sewage and can effectively remove pollutants in the sewage; the sedimentation time of condensation products is shortened, the sewage treatment efficiency is improved, and the treated sewage can reach the emission standards; the treatment agent is simple and convenient to produce and small in investment, takes effects quickly and is free of secondary pollution.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an industrial printing and dyeing sewage treatment agent and a preparation method thereof. Background technique [0002] 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 for printing and dyeing, 80-90% of which is discharged as printing and dyeing wastewater. Common treatment methods include recycling and harmless treatment. Recycling: (1) Wastewater can be recycled according to the characteristics of water quality, such as the diversion of blea...
