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 produced by leather 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 leather 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 processing, in particular to a precipitation reagent for processing leather waste water, and a preparation method thereof. The precipitation reagent is prepared from the following raw materials in parts by weight: 20-25 parts of nanometer calcium oxide, 15-17% of modified potassium hydroxide, 12-14 parts of calcium carbonate, 10-12 parts of kieselguhr, 15-17 parts of bentonite, 16-18 parts of activated carbon particle, 20-25 parts of nano-zinc oxide, 20-25 parts of nanometer aluminium oxide and 6-8 parts of nanometer sliver particle powder. The precipitation reagent has the characteristics of simple method, low cost, better processing effect and higher processing efficiency.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a precipitation reagent for treating leather wastewater and a preparation 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 produced by leather 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, there is a problem that the existing leather waste water lacks the use of reagents for effective treatment, which will cause great pollution to nature. Contents of the invention [0004] In order to solve the above-mentioned technical problems existing in the existing leather wastewater, the ...
