发布时间：2019-08-20 14:18
【摘要】：为进一步准确地测定城镇生活源污水污染物的产生系数,采用问卷调查、SPSS统计分析和监测等方法,分析确定了北京某半封闭区域的当量人口,测定了污水流量和主要污染物浓度,准确地计算了生活源污水污染物产生系数。结果表明,该区域内污水流量时变化系数为2.0,日变化系数为1.1,总变化系数为2.2,人均日污水量为127.47L;城镇生活源污水污染物COD、NH3-N、TN和TP的产生系数分别为(52.5±12.2)g/(人·d)、(7.2±0.8)g/(人·d)、(9.0±1.0)g/(人·d)、(0.89±0.13)g/(人·d),可为我国污染物总量控制提供支持。
[Abstract]:In order to further determine the generation coefficient of sewage pollutants from urban domestic sources, the equivalent population of a semi-closed area in Beijing was analyzed and determined by means of questionnaire survey, SPSS statistical analysis and monitoring, the sewage flow rate and the concentration of main pollutants were measured, and the generation coefficient of sewage pollutants from domestic sources was calculated accurately. The results show that the variation coefficient of sewage flow is 2.0, the diurnal variation coefficient is 1.1, the total variation coefficient is 2.2, and the per capita daily sewage quantity is 127.47L. The production coefficients of COD,NH3-N,TN and TP are (52.5 卤12.2g / (human d), (7.2g) g / (human d), (9.0g 卤1.0g) g / (human d), (0.89 卤0.13) g / (human d),) can provide support for the total amount control of pollutants in China.
