Abstract

The invention discloses a special efficient low-cost sewage treatment agent for domestic sewage. The special efficient low-cost sewage treatment agent is prepared from, by weight, 20-25 parts of polyacrylamide, 28-32 parts of pulverized fuel ash, 2-5 parts of ferrous sulfate, 1-3 parts of ethylene diamine tetraacetic acid disodium salt, 5-8 parts of dichloroethyl ether, 2-5 parts of sodium hydrogen carbonate, 1-4 parts of glycerin monostearate, 17-20 parts of sepiolite, 13-16 parts of cross-linked rectorite, 3-7 parts of gluconic acid sodium salt and 10-15 parts of polymeric ferric sulfate. The invention further discloses a preparation method of the special efficient low-cost sewage treatment agent for domestic sewage. The prepared sewage treatment agent is low in cost, good in effect and convenient to use, and development of domestic sewage treatment industries is facilitated.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a high-efficiency and low-cost sewage treatment agent for domestic sewage 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 con...
