摘  要:
为了研究不同水质水体的自净能力和自净规律,选择了4种不同污染水平的水体进行了室外模拟实验,对水体的CODCr、氨氮和总磷等指标进行了跟踪监测,采用了对比分析、逻辑模型分析等数据分析方法,分析研究了不同水质水体的自净能力及自净规律,提出了不同水质水体中CODCr、氨氮、总磷的自净能力,分析出CODCr和氨氮的自净符合对数衰减规律、总磷的自净规律符合线性衰减。

摘  要:
Four different pollution concentrations water were studied in order to figure out the water bodies' self-purification capacity and contamination decays tendency.The CODCr,NH3-N and TP of the studied water were tested in the researching period and their changes were analyzed to figure out how did the water to reduce those contaminations under the condition without any other human interruptions.The results showed that the CODCr and NH3-N might reduce in logarithm law while TP reduce linearly.
