N2 - 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, NH4+-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, NH4+-N, TN, TP. Physiological characteristics of Nymphaea tetragona have a remarkable impact on the treatment ability of plant purifying-tanks.
