星云湖入湖污染负荷研究

摘要

1999年对星云湖十二条主要入湖河流及湖面降水、降尘进行的实际监测调查表明，入湖河流、地表散流、降水、降尘实际进入星云湖的主要污染物总量为：CODcr：1983.8t、BOD5：360.27t、SS：26460.5t、NH3-N：165.18t、TN：228.23t、TP：184.226t。污染物入湖一般以河流方式为主，但磷主要通过降尘方式入湖，降水载入的氮量也不容忽视。%The monitoring report on 12 in-lake rivers of Xingyun Lake, lake surface precipitation and dust fall shows that the main pollutants brought about are CODcr1893.8t,BOD5360.27t,SS26460.5t, NH3-N165.18t,TN228.23t and TP184.266t,Although pollutants enter lake commonly through rivers, phosphate comes in with dust fall and Nitrogen with rainfall.
