Ecological pool was constructed to treat the eutrophic water in fishpond in Hangzhou Botanical Garden,and the difference of TN,NH_3-N,NO_3-N,TP,COD_(Mn),BOD_5,DO,TURB,COND were analysis.

• 结果表明该生态池在每年的不同季度内对总氮(TN)、氨氮(NH3-N)、总磷(TP)、化学需氧量(CODMn)、五日生化需氧量(BOD5)、溶解氧(DO)、浊度(TURB)、电导率(COND)均有较好的改善和净化效果,对硝态氮(NO3-N)的净化能力稍弱;
