摘要
冬季水库水温9~20℃,浑浊度在3~15NTU之间,阳光充足时,藻类较多,投加聚合氯化铝净化处理由于矾花轻而小,在沉淀池易出现“反池”现象,水质浑浊度指标难以保证。通过加入黄泥粉和少量高锰酸钾,使矾花结大加重,可以克服“反池”现象,达到较好的沉淀净化效果。
Based on introducing the concept and category of significant pollution accident, reviews of the progress of risk management are presented. Discussions of the risk management are carried out from the following aspects : prevention, emergency response and sequential management. Moreover, main contents and methods of prevention, emergency response and sequential management are described in detail. Finally, prospects of risk management of significant pollution accident are put forward.
