摘　　要：随着城市的发展,城市内很多河道水质变差,因此提升河道水质十分有必要。文章针对某城市河道分析了水质恶化的主要原因,包括面源污染、农村生活污水以及河道底泥污染等,并提出一系列水质提升的技术措施,如水环境改善措施、水生态修复措施、基底修复措施、人工湿地构建等。研究表明:通过以上多种措施,可达到削减来水污染物、增强水生植物的生态环境的自净能力以及观赏功能。在此基础上,水体环境可得到长期稳定改善,实现断面水质年均值达到《地表水环境质量标准》中Ⅲ类水质目标。With the development of the city,the water quality of many rivers in the city becomes worse,thus improving the water quality of the river is very necessary.This main causes of water quality deterioration in a city river are analyzed,such as non-point source pollution,rural domestic sewage and river sediment pollution,and a series of technical measures are put forward to improve water quality,including water environment improvement measures,water ecological restoration measures,basement restoration measures,construction of constructed wetlands,etc.The research shows that the above measures can reduce the inflow pollutants and enhance the self-purification ability and ornamental function of aquatic plants.On this basis,the water environment can be steadily improved for a long time,and the annual average water quality of the section can reach the water quality target of Class III in the“Surface Water Environmental Quality Standard”.
