Problems solved by technology

If domestic sewage is discharged directly into the natural world without treatment, it will inevitably pollute the natural world
[0004] At present, there are many products used in domestic sewage treatment and purification, but the treatment effect is generally not good, and the cost is high. The market urgently needs special sewage treatment agents for domestic sewage with excellent performance.

Abstract

The invention discloses a high-efficiency sewage treatment agent and a preparation method thereof. The high-efficiency sewage treatment agent consists of the following raw materials in parts by weight: 25-30 parts of polyacrylamide, 3-6 parts of chitosan, 2-5 parts of aluminum potassium sulfate dodecahydrate, 4-7 parts of activated carbon, 12-15 parts of polyethyleneimine, 2-4 parts of ferrous sulfate, 1-3 parts of sodium citrate, 16-19 parts of leftover bits and pieces of edible mushrooms, 10-13 parts of bentonite and 3-5 parts of starch xanthate. The invention also discloses the preparation method of the high-efficiency sewage treatment agent. The sewage treatment agent prepared through the preparation method disclosed by the invention has good treatment effect to domestic sewage and good stability, a product of the sewage treatment agent can meet the requirements of the market on a domestic sewage treatment product, and the index of the treated domestic sewage can reach the national discharge standard.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an efficient sewage treatment agent and a preparation method thereof. Background technique [0002] China's per capita water resources are small and the spatial distribution is uneven. With the acceleration of urbanization and industrialization in China, the demand gap for water resources is also increasing. In this context, the sewage treatment industry has become an emerging industry, and it is in the same important position as the tap water production, water supply, drainage, and reclaimed water reuse industries. [0003] Domestic sewage is the sewage produced in the process of human life, and it is one of the main pollution sources of water bodies. Mainly feces and washing sewage. The amount of domestic sewage discharged by each person in the city is 150-400L per day, which is closely related to the living standard. Domestic sewage contains a large amount of orga...
