| 摘 要： | 本文较全面地研究了城市污水中的铅在模拟预处理稳定塘中的归宿。不论在哪种预处理稳定塘中，悬浮颗粒态锅的沉降作用是去除污水中铅的主要作用。进入城市污水中的铅，大部分和污水中的悬浮物结合转变成悬浮颗粒态铅，它们输入到模拟预处理预处理稳定塘，这些悬浮颗粒态铅即可在很短的时间内（１ｄ）通过沉降作用得以有效地去除。停留时间分别为１，２，３，５和１０ｄ的实验表明，模拟预处理稳定塘对城市污水中铅的去除率可达５２－

| Abstract: | The fate of Pb in the simulation stabilization ponds was studied. In all kinds of stabilization ponds, the precipitation of particulate Pb is the major mechanism for Pb removal from municipal sewage. The great part Pb in municipal sewage could link with suspend solids and formed particulate Pb rapidly. They could be removed effectively (in one day) through precipitation. Results of tests for 1,2,3,5 and 10 days (hydraulic retention time HRT) showed that the removal rate of Pb in the stabilization ponds was 52-71% , and the Pb removal rate was increased as HRT extended, and the ponds with water hyacinth and diversion panels could improve the Pb removal from municipal sewage. |
