生物膜电极反应器降解对氨基二甲基苯胺的研究

Studies on the 4-Amino-dimethyl-aniline Hydrochloride Degraded by a Bio-electro Reactor

4-Amino-dimethyl-aniline hydrochloride is one of the main components of the wastewater from vanillin production plant. So it is used for the target contamination to be degraded by microorganism, electrochemical oxidation and bio-electro reactor in this paper. We found out a economical, efficient and non-polluted methods for the treatment of wastewater from vanillin production plant. The results indicate that there are a lot of special microbes and bacteria eating 4-amino-dimethyl-aniline hydrochloride in the activated sludge after 20 days′ incubation, at the same time, a stable bio-filmed electrode was formed. Under the condition of 25 ℃, pH=6—7. The use of bio-electro reactor not only increased the biodegradability and decreased the electrical energy consumption, but also solved the problem which the second pollution of organic compounds containing chlorine in the process of indirect electrochemical degradation on the organic pollutants.
