Domestic sewage purification agent and preparation method thereof

Abstract

The present invention discloses a domestic sewage purification agent and a preparation method thereof, wherein the domestic sewage purification agent comprises, by weight, 10-25 parts of polyacrylamide, 10-25 parts of ferric chloride, 10-20 parts of sodium thiosulfate, 7-20 parts of lignin, 5-10 parts of sodium hypochlorite, 5-10 parts of polysaccharide, 5-8 parts of cortaderia selloana, 5-8 parts of typha orientalis presl, 5-8 parts of diethyl malonate, 2-7 parts of maifanite, 2-8 parts of sweet potato starch, 1-5 parts of soap powder, 0.01-0.1 part of plant essential oil, and 50-100 parts of deionized water.. According to the present invention, the coordinating effect is provided by compounding the raw materials, such that the contents of COD, BOD and SS in domestic sewage are significantly reduced, the treated water quality achieves the national sewage discharge standard requirement, and the treated sewage can be recycled, and cannot cause secondary pollution to the natural world; and the used raw materials have the low price so as to provide the low production cost, the domestic sewage treatment process is simple, and the domestic sewage treatment effect is good.

Description

technical field

[0001] The invention relates to the technical field of sewage treatment, in particular to a domestic sewage purifying agent and a preparation method thereof. Background technique

[0002] Water is the source of life. In people's traditional concept, water is inexhaustible. However, with the continuous advancement of urbanization, people's demand for water resources is increasing. After entering the new century , water resources have been depleted and polluted. my country's urban domestic sewage discharge is increasing day by day, but the sewage treatment rate is low, less than 50%, so it is very important to strengthen the treatment of domestic sewage.
