地处上海市南部的日晖港,自50年代以来,就担负着沿港工矿及环卫部门的水运任务,同时又被当作肇嘉浜泵站排放合流污水的一条大明渠。1992年,最高日排入日晖港的合流污水量已达100余万t。长年累月排放的污水严重地污染了河浜,造成日晖港终年黑臭、环境恶化,既影响周围居民健康,也有碍观瞻。70年代所建输送污水的南干线,仅部分容纳肇嘉浜泵站输送的污水,而未充分发挥应有功能,留有较大余量。为此,配合制定肇嘉
Located in Rihui Harbor in the south of Shanghai, since the 1950s, it has undertaken the task of water transport to the industrial, mining and environmental protection departments along the harbor and at the same time has been regarded as a large open channel for the discharge of confluent sewage from the Zhaojiabang pumping station. In 1992, the maximum amount of wastewater that had been discharged into Rihui Harbor reached more than 1 million tons. The sewage discharged over many years has seriously polluted Hamam River and caused a black and smelly weather all the year round in Rihui Harbor.

In the 1970s, the southern trunk line for sewage was built, only partially accommodating the sewage transported by the Zhaojiabang pumping station, which did not give full play to its due functions and left a large margin. To this end, with the development of Zhao Jia
