巢湖施口水域酚的自净规律研究

Study on Self Purification of Phenol in Shikou Water Area of Chaohu Lake

应用野外观测和室内模拟方法， 研究了酚在巢湖施口水域的自净规律。结果表明， 酚在巢湖湖水中的衰减符合一级反应速率方程Ｃ＝ Ｃ０ｅＫｔ。在有水流稀释的情况下， 含酚污水的自净因素主要是水流的稀释作用；在无水流稀释的情况下，水体中微生物的生化作用、光化学氧化作用。

With the open observations and indoor simulated tests, we studied the self purification of phenol in the Shikou water area of Chaohu Lake The results showed that phenol degradation rate followed first order kinetics equation C=C 0e -Kt On the condition of water washing, the factor affecting phenol degradation was mainly streams dilution; meanwhile, biodegradation, photooxidation, sediment adsorption, and volatilization also played important roles
