摘　　要：对位于山东中南部的云蒙湖前置库系统进行了全年跟踪监测,通过春夏秋冬四季的数据反映了具体研究概况,原位监测前置库系统沉淀区、浅水生态净化区和深水生态净化区对水体氮磷及藻类的去除率,反映了复合前置库技术对水体的净化效率,结果表明:前置库系统全年对水体具有良好的净化效果,水体中氮磷等营养物质及藻类密度在流经前置库各系统过程中均呈下降趋势,前置库系统对水体总磷(TP),溶解性活性磷(SRP),颗粒态磷(PP),总氮(TN),硝态氮(NO3--N),氨氮(NH3+-N),藻类的净化率平均分别为47.83%,56.92%,46.94%,34.73%,33.40%,55.71%,34.41%。各净化区对水体氮磷及藻类的去除效果存在差异,相对其他区域前置库浅水生态净化区对水体净化效率较高。PP的含量在深水生态净化区由于水体的风浪扰动等作用呈上升趋势。植物生长将氮磷富集于体内是对水体净化的一个主要原因。The pre-reservoir system of Yunmeng lake in the south of Shandong province was monitored all year, the four seasons data was collected to study the changes of the system. The purification ratio of nitrogen, phosphorus and algae concentration in pre-reservoir precipitate zone, shallow ecological purification zone and deep ecological purification zone was monitored in suite. The effect of pre-reservoir technique on water purification was studied. The results indicated that pre-reservoir system has nice purification function, the nutrition and algae density reduced when water flew the pre-reservoir system, the average purification ratio of total phosphorus （TP）, soluble reactive phosphorus （SRP）, particulate phosphorus （PP）, total nitrogen （TN）, nitrate nitrogen （NO3--N）, ammonia nitrogen （NH3＋-N）, algae were 47.83%, 56.92%, 46.94%, 34.73%, 33.40%, 55.71%, 34.41%. The purification ratio of nitrogen phosphorus and algae in different zone has difference. The purification ratio in shallow ecological purification zone was larger than that of precipitate zone and deep ecological purification zone. PP concentration was raised in deep ecological purification zone, wind disturbed the sediment suspension might the main reason for the rise of PP. the rest fractions of nitrogen and phosphorus and algae concentration was decreased in different purification zone. One of the main reasons of water body purification was plant enrichment.
