摘　　要：塘河水系地处经济发达的江南地区,为典型的经济高速发展区域,经济的高速发展带来的环境问题较为突出。水系主要存在雨污混接口、污水口直排导致水质长期处于劣V类水体,生态系统紊乱,自净能力差。为提升河道水质,恢复河道生态系统,提高河道自净力,实现河道长治久清,在上游雨污管网改造、截污控源、引水补水的基础上采用排口原位净化工程、河道水质净化工程、河道水生动植物生态系统构建工程,水质已经提升到地表IV,最大限度地提升了河道自净力,实现了河道生物多样性,呈现出鱼翔浅底的美景。Water system of Tanghe Riveris located in the economically developed Jiangnan region.It is a typical region with rapid economic development which has brought prominent environmental problems.The major problems of water system are rain-sewage mixing interface,sewage outlet direct discharge leading to the water quality in poor V class water body for a long time,ecosystem deficiency,and a poorself-purification ability.To improve the water quality,restore the ecosystem of the river,improve the self-purification of the river and keep the river clean permanently,upstream rain sewage pipe network is transformed and the sewage source is controlled.What′s more,on the basis of water diversion and water replenishment,water quality has been promoted to the surface IV through the situ purification of discharge outlet project,river water quality purification project and aquatic flora and fauna ecosystem construction project which maximizes the self-purification capacity of the river,realizes its biodiversity,and presents the beautiful scenery of shallow bottom for fish gliding.
