合流制排水系统 meaning in Chinese
combined drainage system
Examples
- The disinfection of the combined sewer overflows
合流制排水系统溢流污水消毒处理 - Intercepting ratio is an important parameter in the rehabilitation of combined sewer system ( css ) and plays a decisive role to the environmental benefit 、 construction investment and operating cost
截流倍数是合流制排水系统截流改造中的重要参数,它的大小对截流改造工程的环境效益、建设投资以及运行成本均起着决定性作用。 - At the same time , study on the relation between them needs calculating quantitatively combined sewer system overflow ( cso ) spill volume 、 time and water quality and study the self - purification of contamination in receiving water
研究截流倍数与水体环境质量之间的关系,则需要定量计算合流制排水系统的溢流水量、水质以及溢流时间,并在此基础上研究溢流污水在水体中的净化过程。 - Thus it is very difficult to calculate the spill volume and water quality because they involve many processes such as rainfall , yield runoff of rainfall 、 flow concentration of surface runoff , ground pollutant build up 、 washout , the flow concentration of combined drainage system and cso
其中,合流制排水系统的溢流水量、水质的确定涉及到降雨,地面产流、汇流,地表污染物的累积、冲刷,污水在管渠中的汇流以及溢流等多种因素,采用一般方法很难定量计算。 - In order to calculate quantitatively the process of rainfall - runoff , the css model of zhang cha catchment is developed based on epa ’ s swmm ( storm water management model ) in this paper . and then calculate cso spill water quality 、 spill volume and spill time at different intercepting ratio using the developed swmm , and analyze the effect on them by intercepting ratio
为了实现上述降雨?径流过程的定量计算,本文引入美国环保局的城市暴雨水管理模型( swmm )建立了佛山市张槎排水区的合流制排水系统模型,使用该模型计算了不同截流倍数时溢流污水的水质、水量以及溢流时间,并分析了截流倍数对它们的影响。
