Abstract

The present invention is process of treating refractory organic effluent with free radical and the electrically catalyzed reactor therewith. The present invention features that in an electrochemically hydrating proton reaction kettle and in the presence of initiator, free hydroxyl radical, superoxide anion free radical, free nitrogen radical, active free oxygen radical, etc are generated circularly and reacted in an electrically catalyzing high pressure reaction kettle with various kinds of refractory organic compounds for efficient decomposition. The present invention has high organic waste water degrading rate and low cost, and is suitable for high concentration organic waste water treatment in papermaking, petrochemical and other industry.

Description

technical field The invention relates to the technical field of high-concentration refractory sewage treatment, and relates to a method for treating highly difficult organic waste water using free radical technology and an electrocatalytic fast reaction device thereof. Background technique High-concentration refractory wastewater has the characteristics of high pollutant content, high toxicity, serious hazards, refractory biodegradation, complex treatment process, and high purification investment and operation costs. A series of problems caused by high-concentration refractory wastewater, such as water pollution, ecological environment deterioration, threats to human health, and hindering the development of related industries, have attracted more and more attention from all walks of life and environmental protection departments of governments at all levels. However, because conventional wastewater treatment methods are difficult to purify or cannot meet the technical and ec...
