Abstract

A sewage treating agent is prepared from, by weight, 10-15 parts of calcium bicarbonate, 10-20 parts of polyacrylamide, 20-40 parts of aluminum polychlorid, 3-7 parts of carbon black, 2-10 parts of activated carbon, 3-7 parts of magnetite, 5-15 parts of iron slags, 20-30 parts of diatom ooze, 30-50 parts of bentonite and 10-15 parts of flyash .The invention further discloses a preparing method of the sewage treating agent, and the preparing method mainly includes the steps of raw material smashing, airing, mixing, pelleting and the like .The sewage treating agent can separate sewage into sediment and clean water, and water quality is good after the sewage is treated .

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a sewage treatment agent and a preparation method thereof. Background technique [0002] Due to population growth and economic development, a series of problems affecting the quality of resources caused by excessive exploitation and irrational development and utilization of resources have directly threatened the survival of us and future generations. [0003] Our country is also facing these problems. Our country is a country with scarce water resources. How to alleviate the shortage of water resources and pollution has become an urgent problem. [0004] At present, there are physical, chemical, biological, comprehensive and other methods to deal with the pollution of water resources, but most of the physical methods have problems of poor treatment effect and unstable treatment rate; the cost of biological methods is too high to be popularized and used; Chemical methods ...
