Problems solved by technology

[0002] In daily production and life, water plays an extremely important role as a necessity for human beings. However, with the continuous improvement of living standards and technology, the pollution of water quality in today's society is extremely serious, especially the sewage generated by printing and dyeing factories. , and in many cases, humans do not treat the generated sewage, but directly discharge it into nature, which brings great pollution to nature
[0003] Therefore, the existing printing and dyeing wastewater lacks the use of reagents for effective treatment, which will cause great pollution to nature.

Abstract

The invention relates to the technical field of sewage treatment, and particularly discloses a precipitant for treating printing and dyeing sewage and a preparation method of the precipitant. The precipitant is prepared from the following raw materials in parts by weight: 8-10 parts of nano calcium oxide, 4-5 parts of modified potassium hydroxide, 6-8 parts of calcium carbonate, 5-6 parts of diatomite, 4-5 parts of bentonite, 3-4 parts of activated carbon particles, 7-10 parts of nano zinc oxide, 7-10 parts of nano aluminum oxide and 0.8-1 part of nano silver particle powder. The precipitant has the characteristics of simple method, low cost, better treatment effect and higher treatment efficiency.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a precipitant for treating printing and dyeing sewage and a configuration method thereof. Background technique [0002] In daily production and life, water plays an extremely important role as a necessity for human beings. However, with the continuous improvement of living standards and technology, the pollution of water quality in today's society is extremely serious, especially the sewage generated by printing and dyeing factories. , and in many cases, humans do not treat the generated sewage, but directly discharge it into nature, which brings great pollution to nature. [0003] Therefore, the existing printing and dyeing wastewater lacks the use of reagents for effective treatment, which will cause great pollution to nature.
