Electric biological processing device and method for waste water containing heavy metal ion and non-degradable organism

Abstract

The present invention relates to electric and biological processing apparatus and method for waste water containing heavy meal ion and non-degradable organism. The apparatus includes electric and biological reaction tower with top air outlet, bottom air distributor, liquid inlet in the upper part, liquid outlet in the lower part and connected with precipitator, tower wall and tower core constituting one electrode pair and insulating layer outside the tower wall. The present invention has the advantages of multi-dimensional electrode reinforced electric field to promote the electrochemical reaction and directional motion of heavy metal ion, and catalytic electrode / efficient functional microbe group with coupled reaction to degrade organic waste water. The present invention can treat waste water containing heavy meal ion and non-degradable organism effectively.

Description

technical field

[0001] The invention relates to industrial waste water treatment technology, in particular to an electrobiological treatment device and method for heavy metal ion-containing and refractory organic waste water. Background technique

[0002] With the development of modern industry, more and more chemical products continue to bring more convenient and rich material life to human beings. But at the same time, during the production and use of these products, many organic substances produced will not only seriously pollute the environment, but also are difficult to be biodegraded, such as phenol, chlorophenol, nitrobenzene, various dyes and their intermediates. body and so on. At present, coagulation degradation, high-temperature oxidative degradation, biodegradation, and electrolytic degradation are commonly used in China to treat such substances. Among them, the coagulation degradation treatment device can effectively remove some p...
