| 摘 要： | 渗流式生物床是受严重污染小型河流强化治理的适宜技术,在中国北方河流污染的治理中有良好的应用前景。冬季由于水温较低带来的去除效果下降是北方河流污染治理的关键问题,本研究在现场中试基础上,考察了一年四季不同水温条件下渗流式生物床处理污染河水的性能。研究表明:渗流式生物床对河水中的CODCr、NH3-N、浊度有较好的去除效果。去除效果和去除负荷受水温影响较大。

| Abstract: | The seepage biological bed (SBB) is the advisable technique for the treatment of heavily polluted water in small-river,and has good prospect in the application of the polluted river management in the north of China.The poor operation performance in winter due to low water temperature, is one of main difficulties that affecting polluted river water treatment in the north of China.Based on the field pilot-scale experiment for the whole year,the effect of water temperature on polluted river water treatment by SBB is studied.The study shows that SBB has a good effect of removing COD_ Cr ,NH_3-N and turbidity in river water; the removal rate and loaging are affected greatly by water temperature. |
