Abstract

The invention provides a multifunctional environmentally-friendly sewage treatment agent. The multifunctional environmentally-friendly sewage treatment agent comprises the following raw material components in parts by weight: 24 to 27 parts of poly-aluminum chloride, 16 to 18 parts of sodium carboxymethyl starch, 25 to 30 parts of sodium polyacrylate, 8 to 10 parts of potassium ferrate, 15 to 20 parts of corncob, 10 to 12 parts of pine sawdust, 13 to 15 parts of medical stone, 18 to 20 parts of coal ash, 10 to 12 parts of vermiculite, 8 to 10 parts of tourmaline powder and 13 to 15 parts of pyrophyllite. The sewage treatment agent with multiple functions of flocculation, oxidation, adsorption and sterilization can be prepared by a specific formula and a specific preparation method, can efficiently remove harmful organic substances, inorganic substances and heavy metal ions in the sewage, also can effectively kill microorganisms such as bacteria in water, and can avoid more serious pollution to the water caused by excessive breeding of the microorganisms.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a multifunctional environment-friendly sewage treatment agent and a preparation method thereof. Background technique [0002] Urban sewage treatment is the centralized treatment of urban sewage discharged from the city and sewage discharged from factories, that is to say, urban sewage includes domestic sewage and industrial sewage. If urban sewage is directly discharged into water bodies without treatment, it will bring heavy pressure to the water environment, seriously endanger people's drinking water health, seriously threaten limited water resources, and even threaten people's survival and development environment. Therefore, most urban sewage needs to be centrally treated by urban sewage treatment plants, so that the sewage can meet the corresponding national sewage discharge standards after treatment, and then it can be discharged into water bodies. Traditional water...
