Embodiment Construction

[0032] Below in conjunction with accompanying drawing and comparison with prior art content of the present invention will be further described:

[0033] Such as figure 2 Shown is the flow chart of the multi-dimensional electrolytic sewage treatment process, including mixing adjustment, catalytic activation, anion and cation separation, electrolytic redox, and filtration separation. The following is a comparison of operating costs between the multi-dimensional electrolysis process system and the traditional electrolysis process system.

[0034] Comparison of treatment costs for organic matter in wastewater

[0035] 1) The use of multi-dimensional electrolysis technology can save a lot of chemicals. In multi-dimensional electrolysis, the activity of wastewater is very strong, and the suspended organic matter is almost completely decomposed. Good processing effect.

[0036] 2) The multi-dimensional electrolysis process system does not need to adjust the pH value of the wastew...

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...
