Multi-dimensional electrolysis sewage treatment process

Abstract

The invention provides a multi-dimensional electrolysis sewage treatment process used for treatment of high-concentration organic matter and high-salinity wastewater in the industries such as chemical engineering, printing and dyeing, pharmacy, papermaking, oil fields, food processing and refuse leachate. The process is characterized by including the steps of mixed regulation, catalytic activation, cation and anion separation, electrolytic oxidation reduction and filtering separation; treated water is drained after it is detected that the treated water reaches the standard, due to the fact that organic matter is completely decomposed, no sludge residue is left, a multi-dimensional electrolysis sewage treatment device is adopted for electrolytic catalytic oxidation, and removal of organic matter and NH3-N of multi-dimensional electrolysis in a catalytic electrolysis method is achieved through a direct oxidation effect of an anode and an indirect oxidation effect of a catalyst solution. The process has the advantages of being low in operating cost, small in occupied area, small in amount of generated sludge, low in disposal cost of the sludge and the like.

Description

technical field [0001] The invention relates to a multi-dimensional electrolytic sewage treatment process in the field of sewage treatment. Background technique [0002] While the continuous development of contemporary social chemistry has promoted the progress of human society, it has objectively caused serious environmental pollution. These problems also hinder the sustainable development of society to a certain extent. At present, the only way to solve these environmental problems is to vigorously develop green chemistry. Among these many problems, the green treatment of wastewater is a hot topic at present. In the 1960s and 1970s, with the rapid development of the power industry, the research on coated titanium anodes was successful, and the research on electrochemical theory continued to deepen. This provides a theoretical basis for the degradation of organic pollutants by electrocatalytic oxidation, thus promoting the application of electrolysis technology in wat...

Problems solved by technology

However, the existing electrolysis method is usually made of noble metal plates, which is expensive; at the same time, in the treatment of high-concentration wastewater, in order to obtain higher electrolysis energy, it can only be achieved by increasing the voltage and current, resulting in excessive energy consumption and operating costs. Too high, not conducive to the realization of industrialization
