Composition formula for sewage treatment and preparation method of composition formula

Abstract

The invention discloses a composition formula for sewage treatment and a preparation method of the composition formula. The composition formula comprises the following raw materials in parts by weight: 23-25 parts of calcium carbonate; 0.3-0.7 part of calcium chloride; 8-12 parts of ethanol; 3-5 parts of sodium hypochlorite; 4-10 parts of alum; 16-20 parts of bentonite; 9-11 parts of barite powder; 14-18 parts of clay; 12-15 parts of ferric chloride; and polyacrylamide, polyaluminum chloride and the like. The preparation method comprises the following steps of: S1, preparing materials; S2, grinding the materials into powder; S3, preparing slurry; S4, mixing the materials; S5, performing drying; and S6, performing pulverizing. According to the designed composition, through mutual cooperation of the calcium chloride, sodium hypochlorite, alum, polyacrylamide and polyaluminum chloride, the composition has a good absorption effect on bacteria, microorganisms and phosphorus and ammonia pollutants in sewage; the raw materials of the composition are abundant in source and are low in price, and therefore, production cost is effectively reduced, and the composition is suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a composition formula for sewage treatment and a preparation method thereof. Background technique [0002] In the process of sewage treatment, COD, ammonia nitrogen and total phosphorus are the key indicators of whether the treatment is up to standard. The prior art discloses a variety of compositions for treating sewage, but their treatment effects on high concentrations of COD, ammonia nitrogen and total phosphorus in sewage are not good. After retrieval, the Chinese patent application number 201610325377.3 discloses a composition formula for sewage treatment and its preparation method, wherein the composition formula includes the following raw materials in parts by weight: calcium carbonate, 20-30 parts; silicon micropowder, 5-15 parts; clay, 15-25 parts; kaolin, 5-15 parts; borax, 10-20 parts; mica, 5-15 parts; zeolite powder, 5-15 parts; perlite, 10-20 parts; silic...
