| 中文摘要 | 河道滞留塘系统是一项适用于中小型污染河流净化的生态技术,在我国中小型河流污染治理中有较好的应用前景。通过近1年的现场试验,考察了河道滞留塘系统对河水中有机污染物的净化效果。结果表明,温度和溶解氧对COD的去除效果无影响;颗粒态有机物的重力沉降是滞留塘去除COD的主要机理;其对COD的去除率可达30%,最高去除速率约2 g/(h.m2)。由于COD去除速率有75%的几率介于0.2~1.1倍的SS去除速率,因此可通过测定SS去除速率来预测对COD的去除速率。; The On-stream Detention Pond System(OSDPS) is an ecological technology which is suitable and promising for purification and restoration of polluted small-scale streams in China.Chemical Oxygen Demand(COD) removal efficiency of OSDPS in different seasons was detected after one-year of field experiments.The study shows that the temperature and DO have no apparent effects on COD removal efficiency,and the particle settling is the main mechanism of removal of COD.The maximal COD removal efficiency is 30% and corresponding rate is 2 g/(h穖~2).Moreover,the removal rate of COD could be predicted by testing the removal rate of SS on the basis of the relationship between them.; 国家“十五”重大科技专项(2003AA601080) |
