摘要:为分析多级生态库塘对入洱海低污染水体的净化效果，以大理市上鸡邑村新建多级串并联库塘为研究对象，跟踪监测了库塘各单元进出口水体中总氮（TN）、氨氮（NH4+-N）、总磷（TP）变化情况，并对库塘净化效果进行分析。结果表明：多级串并联生态库塘对水体中TN、NH4+-N、TP的去除率分别达30.98%～54.96%、54.11%～64.17%、27.11%～47.83%，净化效果较好。库塘对低污染水氮磷去除效果在不同单元和季节存在差异，各净化单元中，稳定塘对水体净化效果最不理想，对水体中TN、NH4+-N、TP去除率分别为2.88%、-17.50%、-16.83%。库塘旱季对水体中氮磷净化效果优于雨季，对水体中 TN、NH4+-N、TP平均去除率分别为46.23%、84.43%、38.61%，均高于雨季。

Abstract:In order to study the purification effect of multi-stage ecological pond for low-polluted water that into Erhai, total nitrogen (TN), ammonia nitrogen (NH4+-N), total phosphorus (TP) changes in inlet and outlet of each pond unit of the multi-stage series pond in Dali village was tracked and monitored, and purification effect of the pond was analyzed. The results showed that the removal rate of TN, NH4+-N, TP of the multi-stage pond were 30.98% to 54.96%, 54.11% to 64.17%, 27.11% to 47.83%. Different purification unit and season had great influence on multi-stage pond removal efficiency. In each purification unit, the effect of stabilization pond on water purification was the most unsatisfactory, the average removal rate of TN, NH4+-N, TP in stabilization pond were 2.88%,-17.50%,-16.83%. The effect of nitrogen and phosphorus purification in the dry season was better than that in the rainy season. The average removal rate of TN, NH4+-N, TP in the multi-stage pond were 38.9%, 27.52%, 36.04% in dry season, and those were 46.23%，84.43%，38.61% in dry season.
