摘  要：
采取现场试验方法,研究了晴天时睡莲对黑臭河水的净化效果与其生理特性的日变化关系.结果表明:随着光强日变化,睡莲叶片的叶绿素、可溶性蛋白含量日变化呈双峰型,峰值约在12:00和14:00,睡莲根组织的过氧化物酶(POD)、过氧化氢酶(CAT)活性日变化呈单峰型,峰值约在13:00;植物净化槽中CODCr,NH 4+-N,TN和TP去除率的日变化呈先升高、后降低的单峰型,峰值约在13:00;睡莲叶片叶绿素、可溶性蛋白含量及根组织POD、CAT活性与植物净化槽的CODCr,NH 4+-N,TN及TP的去除率呈显著相关性,睡莲生理特性对净水效果有显著影响.

摘  要：
Based on field test method,hydroponic plant purifying-tanks were used to investigate the correlation between diurnal variation of black and malodorous river water purification and physiological cha-racteristics of Nymphaea tetragona on a sunny day.The results indicate that with diurnal variation of light intensity,Chla,Chlb and SP contents of the leaves show double-peak style at about 12:00 and 14:00,and POD and CAT activities of the roots show single-peak style at about 13:00.Removal rate of CODCr,NH+4-N,TN,TP of plant purifying-tanks also show single-peak style at 13:00.Chla,Chlb and SP contents of the leaves,POD and CAT activities of the roots have a significantly positive correlation with removal rate of CODCr,NH+4-N,TN,TP.Physiological characteristics of Nymphaea tetragona have a remarkable impact on the treatment ability of plant purifying-tanks.
