Title: Discussion on the Runoff Quality of Rain Flood and Its Utilization Model in Northern Cities
Abstract: According to the situation of the shortage of water resource and the underutilized rainfall resources in northern cities,the rain flood usage engineering modes(collection and utilization of road and roof rainwater engineering modes) suitable for climate characters and economic development in northern cities were discussed by taking Handan City in Hebei Province as an example.Meanwhile,aiming at the serious pollution of rainwater runoff in urban road,as well as the usually more serious pollution degree of initial rainwater than urban sewage,the concentration of pollutant in rainwater was analyzed and compared with the standard of irrigation water quality.Furthermore,the water quality property of road runoff and the change law of pollutant concentration during individual rainfall runoff were studied.The mathematical model of erosion and emission rules of pollutants was established,which offered fundamental data for the runoff utilization of urban road.
