摘要
Abstract
The research aimed to study composite effect of the heavy metal irons Hg2+ and Cd2 + on treatment capacity of the activated sludge system.[Method] Flocculent activated sludge in return sludge pool of the sewage treatment plant as material,Hg2+ + Cd2+ at different concentration combinations were added into artificial wastewater.After conducted aeration culture for 20 b,physiochemical and biological indicators of the effluent were measured.[Result] Composite effect of the heavy metal irons Hg2+ and Cd2+ showed that both MLSS and removal rate of the COD declined.As increase of the heavy metal concentration and prolonging of the test time,COD and MLSS in effluent of each test group were both affected significantly.[Conclusion] Hg2+ + Cd2+ made that activity of the activated sludge and its treatment capacity on sewage both declined.关键词
