摘要:- 珠海市一直重視排洪渠（河涌）的水環(huán)境整治提升工作，先后開展過包括各片區(qū)排洪渠的截污整治工程，通過清污分流、集中截流、涌邊截流和局部排水改造等方式收集污水，但是截污效果不甚理想。對已實施的各種截污方式進行實地調查后發(fā)現(xiàn)，清污分流渠在南屏東排洪渠黑臭水體整治方面效果顯著，能夠充分實現(xiàn)合流制區(qū)域晴天污水全收集、全處理，雨天有效控制溢流污染的目標，同時避免引發(fā)內澇。通過對污染源的控制，后期輔以微生物修復、生態(tài)模擬、納米曝氣、水質提升等手段，共同對河道水體進行生態(tài)修復，基本實現(xiàn)了河涌水體的凈化。
Abstract:- As the local government of Zhuhai has always attached importance to the water environment improvement of flood drainage canals (river branches), sewage interception and regulation projects in various districts have been carried out. Although sewage was collected by means of sewage separation, centralized interception, branch interception and partial drainage transformation, the effect of sewage interception was not satisfactory.After field investigation of various sewage interception practices implemented, it is found that the sewage separation canal has remarkable effect on the regulation of black and odorous water in east Nanping flood drainage canal, which can fully realize the goal of collecting and treating all these wage from confluence system area in sunny days and effectively controlling overflow pollution in rainy days, as well as avoiding waterlogging at the same time. By controlling pollution sources, combined with microbial remediation, ecological simulation, nano- aeration, water quality improvement and other means, the ecological remediation of river water was carried out, and the purification of river water was basically realized.
