摘要
工程针对山地城市河流纵坡大、岸坡陡、工程可利用土地少的特点,通过"四大系统、八大工程"的体系化设计,采取组合工艺,应用新技术、新设备,结合不同水体特点,"一河一策、一库一策",工程实施后,保障河道及水库的主要水质指标(TN除外)达到《地表水环境质量标准》(GB 3838-2002)Ⅳ类标准。
According to the characteristics of the river in mountainous cities-large longitudinal slope,steep bank slope and less land available,the project is designed according to"four systems and eight projects".The design observe the principle"one river,one policy",according to the characteristics of different water bodies.After the project,the main water quality indexes of this basin is expected to reach the ClassⅣstandard of Environmental quality standardsf or surface water(GB 3838-2002)except TN.
