城鎮(zhèn)生活源污水污染物產(chǎn)生系數(shù)的研究
[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 鹵12.2g / (human d), (7.2g) g / (human d), (9.0g 鹵1.0g) g / (human d), (0.89 鹵0.13) g / (human d),) can provide support for the total amount control of pollutants in China.
