Anoxybiotic/aerobic two-section internal electrolysis organic waste water treating method

Abstract

The invention relates to an anoxic / aerobic, two-stage, internal- electrolysis organic waste water treating method, fully mixing iron chips and activated carbon / copper chips in a certain mass ratio, and placing their mixture into a reactor, regulating waste water pH value and then adding the waste water into the reactor in the fixed solid-liquid ratio, firstly making anoxic internal electrolysis reation for a certain period of time and then making aerobic reaction for a certain period of time, adding alkali in the effluent water to make mixing coagulation settlement and discharging supernatant. And the treating mode can adopt a single- groove static flow mode or double-groove continous flow mode. And it fully uses redox reaction to degrade organic matters, and has stronger ability to degreade organic matters difficult to degrade and more remarkable decoloring effect.

Description

technical field

[0001] The invention relates to a method for anoxic / aerobic two-stage internal electrolytic treatment of organic wastewater, which combines the two process conditions of internal electrolytic anoxic and aerobic, and treats difficult organic wastewater by first reducing and then oxidizing. degrade organic matter. It belongs to the technical field of water treatment. Background technique

[0002] At present, with the increasing types of domestic sewage and industrial wastewater, the components are more complex, and wastewater treatment is becoming more and more difficult. With the development of wastewater treatment technology so far, some wastewater with simple components, good biodegradability, and low concentration can be treated by combining traditional processes, such as biological treatment, coagulation, and chemical precipitation. However, many wastewaters contain many refractory organic substances, such as phenols, alkylbenzenesulfonic acids, chloroph...
