摘　　要：针对家庭用景观鱼池水质保持的实际需求,设计并构建了一套停留时间为2 h的生态循环净化系统,研究了该系统的净化能力和水质保持效果。结果显示所设计的生态净化系统可达到较好的CODCr、NH4+-N和NO2--N去除效果,并能将CODCr、NH+4-N和NO2--N分别控制在28、0.5和0.1 mg/L以内;生态净化系统对NO3--N无净化效果,鱼池中NO3--N逐渐积累并占据TN的主要部分。In order to meet the actual demand of protecting water quality for landscape,an ecological recirculated purification system was designed and constructed,the retention time of which was about 2 hours.The results of experiment show that the system can remove CODCr,NH4^＋-N and NO2^--N effectively.CODCr,NH4^＋-N and NO2^--N can be confined below 28 mg / L,0.5 mg / L and 0.1 mg / L,respectively.However,the system seems to have no effect on NO3^--N,which accumulates gradually and becomes the major part of TN during the experiment.
