Abstract

The invention discloses a flocculating agent for sewage treatment. The flocculating agent is composed of the following substances in parts by weight: 20 to 45 parts of graphite powder, 15 to 25 parts of carbon powder, 10 to 15 parts of starch, 6 to 15 parts of sodium carboxymethyl cellulose, 6 to 15 parts of anhydrous ethanol, 20 to 45 parts of ammonium persulfate, 20 to 45 parts of sodium carbonate, 20 to 45 parts of ferric citrate, 5 to 15 parts of ethylene diamine, 15 to 25 parts of sludge powder, 20 to 35 parts of lime powder, 30 to 45 parts of propylene cystamine, 30 to 35 parts of zinc chloride, 15 to 25 parts of aluminum sulfate, 15 to 20 parts of polymeric phosphato-aluminum chloride (PPAC), 8 to 12 parts of slaked lime, 9 to 15 parts of fly ash, and 30 to 50 parts of deionized water. The excitation effect of the flocculating agent and the nucleating performance of gel are both improved. The chemical properties of the flocculating agent are stable. The addition amount of the flocculating agent is reduced. The flocculating speed is quick. The performance on removing suspensions and oil stains is excellent. The water processing performance is enhanced, and the quality of processed water is improved.

Description

technical field [0001] The invention relates to a flocculant for sewage treatment. Background technique [0002] The flocculant is mainly a group with positive (negative) charge and some particles or particles with negative (positive) charge in some water that are difficult to separate, reduce its potential, make it in an unstable state, and use its The aggregated nature allows these particles to be concentrated and separated by physical or chemical means. The agents generally used for this purpose are called flocculants. Flocculants have been widely used in wastewater treatment, and wastewater coagulation treatment is one of the basic units in oily wastewater treatment. In the prior art, the consumption of flocculant is large, the flocculation efficiency is low, and the quality of the treated water is mediocre during wastewater treatment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a flocculant for sewage...
