Abstract

The invention relates to a novel sewage treatment agent, which contains polyferric trichloride, potassium persulfate, aluminum sulfate, polyacrylamide, polyethyleneimine and bentonite, i.e. 20 to 30 percent by weight of polyferric trichloride, 15 to 25 percent by weight of potassium persulfate, 5 to 15 percent by weight of aluminum sulfate, 20 to 35 percent by weight of polyacrylamide, 10 to 25 percent by weight of polyethyleneimine and the balance of water. For the waste water of oil production plants, the novel sewage treatment agent has a good precipitation effect, and the effluent quality is good; the treatment cost is low, and the novel sewage treatment agent is applicable to oily sewage of the oil production plants. After the agent is added into sewage, suspended matters immediately flocculate; produced flocs are big; the precipitation is rapid; the efficiency is high; the flocs have high strength and good hydrophobic property, which are favorable for filter pressing, and the novel sewage treatment agent is high in purity, and does not have impurities and dust.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, and more specifically relates to a novel sewage treatment agent. Background technique [0002] The chemical precipitation method is widely used in sewage treatment. It is to add some chemical agents to the waste water to make it chemically react with the pollutants in the waste water to form insoluble solid products, and then separate the solid and liquid to remove the water. A method of contamination. At present, in some industries, such as coal slime water, oily wastewater from oil fields, printing and dyeing wastewater, papermaking wastewater, etc., the chemicals used have poor treatment effects, slow settling speed, high cost of chemicals, and some enterprises have caused serious corrosion of equipment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a novel sewage treatment agent for the above-mentioned defects of the p...
