Method of removing organic pollutants in water by combined action of fly ash particle electrodes with different densities and electric field

Abstract

The invention discloses a method for removing organic pollutants in water through the joint action of fly ash particle electrodes of different densities and an electric field. 0 to 10 parts of agent (100 parts in total) as raw materials, by adjusting the amount of foaming agent and pore-forming agent (not 0 at the same time), three different densities with density less than water, density equal to water and density greater than water were prepared respectively. fly ash particle electrodes, and then these three different densities of fly ash particle electrodes are combined with an electric field. The present invention is beneficial in that: (1) three kinds of fly ash particle electrodes with different densities can be evenly distributed in the electrolyte without delamination, so that the reaction speeds of the electrolytes in each layer of the electrolyte tend to be consistent, The effect of removing organic pollutants in water is very good; (2) the water treatment equipment adopted is simple, the application and operation are convenient, the cost is low, and the treatment cost is low.

Description

technical field [0001] The invention relates to a method for removing organic pollutants in water, in particular to a method for removing organic pollutants in water through the joint action of fly ash particle electrodes of different densities and an electric field, and belongs to the technical field of sewage treatment. Background technique [0002] Printing and dyeing enterprises consume a lot of water, and the printing and dyeing wastewater produced has the characteristics of high chroma, complex organic components and unstable water quality. At present, my country's printing and dyeing wastewater can discharge 5×10 per day 6 ~6×10 6 m 3 , Printing and dyeing wastewater has become the focus and difficulty of wastewater treatment in my country. Due to the complexity of the type and structure of the dye itself, its biodegradability is very poor. The traditional printing and dyeing wastewater treatment process usually only transfers the pollutants, does not completely el...

Problems solved by technology

Due to the complexity of the type and structure of the dye itself, its biodegradability is very poor. The traditional printing and dyeing wastewater treatment process usually only transfers the pollutants, does not completely eliminate the pollution, and will cause secondary pollution.
