The Annual Pollutant Carry Model Of Highway And The Wood-Pavement In The Tour Area

The superficial pollutant is a kind of contamination source of dispersion, its meaning is that the water is polluted because the dissolved contamination or the solid pollutant were scoured by the big area declines water and radial stream. The superficial pollutants include agricultural superficial pollutant and city earth's surface radial stream. And the highway surface radial stream is the earth's surface radial stream that has single earth's surface usage function to flow. In the past, the highway surface radial stream flows have been a part that the city earth's surface radial stream to take in to study. But in these years, the highway surface stream has gradual develop to a opposite and independent research realm because its severity affection. Along with gradual value of domestic to the environmental protection work, and the water resources is increasingly needy, this study of surface stream seem to be urgent and necessary.In the tradition since the average iliotibial tract of rain affairs flows concentration (EMC) to carry on the estimate of that the highway leontiasis ossea source contamination burden exhausts quantity, but want to obtain average iliotibial tract of have the representative to flow the concentration demand to carry on 30-50 iliotibial tracts to flow an indol test for the basal. Now if want to account the quantity of surface stream , there must be know the EMC. But we had no condition to get the EMC in Jiuzhai valley. So we must find out a model that can avoid the EMC. In Jiuzhai we had made six manual rainfall examinations to get some date. After we had analyzed these date, we found out some rules. Discover after carrying on analysis tired add burden curve to look like to a straight line. Need a little amount and several artificials to rain indol test only and then can acquire to exhaust model according to the pollutant burden of the unit burden coefficient according to this line sexual behavior. Through these rules and other information we had set-up the model: L =αFγPRAE.Use the model, we had accounted the TP of the lakes in Jiuzhai valley. And analyzed the parameter E in the model. In fact, the parameter E should have many condition causes to many results.
