Mechanism and Experimental Research on Treatment of Coal Chemical Wastewater by External Circular Anaerobic Reactor

Abstract:

In view of the defects of existing much “dead area” and decreased effective volume causing by distributing water device of UASB reactor, a new-style of external circular(EC) reactor was developed in this research. In this paper, through laboratory scale and pilot scale study on the external circular anaerobic reactor to treat coal chemical wastewater, we conducted profoundly theoretic and testing analysis on external cyclone-flow distribution water device, the results reveal that the new-style anaerobic reactor can largely advance the mixture of granular sludge with wastewater, enhance the availability of reactor’s cubage, heighten mass-transfer efficiency between substrate and microbes, and avoid effectively the losing of granular sludge, further reduce the cost of disposing coal chemical wastewater, which had very important theoretical indication function and practical application value in the development of coal chemical wastewater treatment by anaerobic technology.
