| 摘 要： | 对北京市一企业园区一处4个串联水池(A-D池)的多级沉淀与生物净化相结合的净化系统的水样进行了实地采样和水质分析,测定了pH、COD、TN、NH4+-N、NO2--N等5项水质指标。结果表明,各项主要污染指标去除率为68.9%~87.6%,净化后水质清洁,达到地表环境水质量标准Ⅱ类水质标准,净化后的水体可用于一般景观水体的补水。物理沉淀与生物净化具备协同作用,其中A、B池沉淀作用更明显,并主要针对TP净化,C、D池生物净化作用更明显,并主要针对COD和N类污染。但两类净化作用表现并不独立,沉淀具初期快速净化作用,生物净化具彻底净化作用。

| Abstract: | The effect of water purification system equipped with 4 series-wound ponds （individuals named pond A,B,C and D respectively）containing the multi-stage sedimentation and biological purification.The pH, chemical oxygen demand （COD）,Total nitrogen （TN ）,ammonia nitrogen （NH 4 ＋-N ）and nitrite nitrogen （NO2 --N）was analyzed.The result indicated that the removal rates of above mentioned contaminations were 78.9%,83.7%,68.9%,79.0% and 87.6% respectively.The water quality of pond D was clean,with qualifying level 2 of environmental quality standard for surface water.So the purified water could be used as replenishment for common landscape water.Results also showed that there was a synergistic effect between sedimentation and biological purification.The pond A and B performed as sedimentation,pond C and D performed as biological pur-ification. |
