Abstract

The invention discloses a municipal sewage treatment agent and a preparation method thereof. The municipal sewage treatment agent is prepared from white alum, calcium aluminate, ferric trichloride, kaolin, polyacrylamide, polyferric sulfate, lime, sodium carbonate, ferric chloride, bentonite, plant fiber and coal ash; the municipal sewage treatment agent comprises the components: 30 to 50 parts of the white alum, 8 to 12 parts of the calcium aluminate, 10 to 20 parts of the ferric trichloride, 10 to 20 parts of the kaolin, 0.8 to 1.2 parts of the polyacrylamide, 1 to 1.4 parts of the polyferric sulfate, 8 to 12 parts of the lime, 4 to 6 parts of the sodium carbonate, 11 to 13 parts of the ferric chloride, 6 to 8 parts of the bentonite, 2 to 6 parts of the plant fiber and 10 to 20 parts of the coal ash. The municipal sewage treatment agent has the advantages of wide source of the production raw materials, environment friendliness and no toxin, good output water quality and high process operability. The medicament disclosed by the invention can be used for treating various types of sewage, such as chemical wastewater of oil fields, mines, steel, electroplating wastewater, dyestuff, pesticide, wine production and chemical industry, and also has a good treatment effect on domestic sewage, wastewater of paper mills, river and lake water, garbage seeping water, leather making wastewater and the like.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an urban sewage treatment agent and a preparation method thereof. Background technique [0002] Urban sewage is all drainage collected through sewer pipes. It is the mixed water of various domestic sewage, industrial wastewater and urban rainfall runoff discharged into the sewer system. If urban sewage is discharged into surface water bodies without treatment, it will cause rivers, Lakes are polluted. The existing sewage treatment agents cannot effectively purify the impurities and chemical components in urban sewage, and the purified water quality cannot be effectively guaranteed. [0003] At present, the coagulants commonly used in sewage treatment agents mainly include inorganic flocculants and organic polymer flocculants. Inorganic flocculants are a new type of water treatment agents developed on the basis of traditional aluminum salt and iron salt flocculants. With the disc...
