The Research on Treatment of Lead-Bearing Waste Water by Xonotlite Simultaneous Training and Domesticating Granular Sludge

The experimental research was carried out to investigate the effect of putting xonotlite to train granular sludge in the training process, the analysis was done that the effect by xonotlite on reactor running, effluent value, microorganism and removing lead, at same time, the SEM as done on microorganism. The result showed that training granular sludge by xonotlite has not only guaranteed reactor´s normal operation, but also promoted the granulation process of the sludge largely. Sludge has higher ability to resistance toxic, the lead remove rate is higher 95%.
