Research on Treatment Technology for the Industrial Wastewaters With High Concentration in China

Sun Peishi,Qian Biao,Hong Pinjie,Harada Yoshiaki,Yang Ying,Hao Yukun

Strategic Study of CAE 2003, Volume 5, Issue 6,   Pages 68-73

Abstract:

By using the introduced CWO technology and its 200 L/d plant, more than 10 kinds of industrial wastewaters with high concentration in China, such as the waste liquor of coking, the black liquor of paper making, the waste mother liquor of bio-pharmacy and so on, were treated in this research. The results showed that the CWO technology and its equipment had a good applicability for treating the industrial wastewaters with high concentration in China. One set of CWO — 20 m3/d industrial plant, as a demonstration engineering installation of CWO technology, was independently designed, made and operated in Kunming city. During the running test, the CWO - 20 m3/d plant displayed a favorable treatment capability for the bio-degradedly difficult industrial wastewaters with high concentration. For the treatment of the waste liquor from coking and the black liquor of paper making, more than 99 % of CODCr and NH3 - N in the wastewater could be removed. The CWO -20 m3/d plant could be run continuously and stably. The treated wastewater could meet the discharge standard and the treatment process with CWO technology showed up a good economic advantage.
