摘　　要：在室内模拟生物净化槽中比较研究了氮磷对污水中藻类叶绿素含量和污水净化的影响。污水中磷含量均为７ｍｇ／Ｌ左右，氮含量分别为７７．４、４４．４、２４．８和１３．５ｍｇ／Ｌ，结果发现ＴＮ／ＴＰ＝７７．４／７．０１ｍｇ／Ｌ组，污水经７ｄ净化，藻类叶绿素含量最高，污水净化效果较好。四个实验组比较，叶绿素含量随ＴＮ／ＴＰ比例的上升而上升，呈显著正相关。The effects of nitrogen and phosphorus on the chlorophyll content of algae inmodel systems of stabilization ponds have been studied in green house during springand summer in 1988 and 1989.When the concentration of TP was all kept consta-ntly at abont 7 mg/L,and that of TN respectively at 13.5,24.8, 44.4 and 77.4mg/L in four experiment series of raw sewage,the increase of chlorophyll content in algae of the sewage was observed with the ratio of TN to TP。 The highest chlorophyll content was detected when the TN/TP ratio equals to 77.4/7.0 1 mg/L, and so was the best result of waste water purification.
