Abstract

The invention discloses a treatment method of an environment-friendly surfactant capable of reducing pollution. The method comprises the following treatment steps: S1, regulating the pH value of wastewater, and filtering; S2, bubbling, and removing foams; S3, carrying out electrostatic deposition at the bottom of the wastewater; S4, carrying out layered separation on the wastewater; and S5, filtering lower-layer wastewater. In step S1, a sodium hydroxide solution and an aluminum chloride solution are added into wastewater containing a surfactant to adjust the pH value of the wastewater to 8-9,the concentration of the sodium hydroxide solution is 50-80%, and the concentration of the aluminum chloride solution is 60-90%. The surfactant in the wastewater treatment is removed in a manner of combining bubbling and electrostatic deposition, other pollutants are not generated in the treatment process, the treatment process is more environmentally friendly, the treatment steps are simple andeasy to operate, the surfactant can be effectively treated to reach the emission standard, and the influence of unqualified emission of the surfactant on growth of animals and plants is avoided.

Description

technical field [0001] The invention relates to the technical field of waste water treatment, in particular to a treatment method for an environment-friendly surfactant that reduces pollution. Background technique [0002] Surfactant is an essential additive in the wastewater treatment process. Surfactant is a kind of organic compound that can reduce the surface tension by adding a small amount. It has the functions of dispersing, wetting, penetrating, solubilizing, emulsifying, foaming, Lubrication, sterilization and many other properties are widely used in various fields of the national economy, and are known as "industrial monosodium glutamate". As an important chemical product, the application range of surfactants is still expanding, and the consumption is also increasing; [0003] However, if the wastewater containing surfactants is not properly treated, it will be discharged into water bodies and soils. The presence of a large number of surfactants in the environment w...
