Abstract
In order to improve the construction quality of urban rain and pollution diversion transformation project,relying on a urban rain and pollution diversion transformation project,the construction technology of urban rain and pollution diversion transformation project was systematically analyzed,and the construction effect was parity.The practice shows that the influent COD concentration and NH3-N concentration increase by 64.3%and 41.9%respectively,indicating that the diversion efficiency is significantly improved.The peak COD concentration decreased by 47.2%and SS concentration decreased by 53.6%in rainy season.The annual COD emission is reduced by 2 860 t and NH3-N 173 tons,the flow capacity of the pipeline network is increased by more than 40%,and the risk of waterlogging in the rainy season is significantly reduced.关键词
