- Abstract:
- In order to control the overflow pollution in the watershed, one new super large underground storage tank was built in the lower reaches of Yuhe River in Weifang City. It was used for controlling combined sewer overflow pollution and separate system runoff pollution. With a total volume of 220 000 m3, the storage tank adopted the mode of series water storage, equipped with gate-type self-washing, ion deodorization and other facilities. The design scale, design parameters and operation mode of the project were introduced in detail, and the applicability of the mode of series water storage in the long and narrow area was introduced emphatically. In order to further reduce the project cost, an extra long washing distance was used to decrease washing equipment numbers. The test results indicated that it also got a well flushing effect by increasing the water amount and flushing potential energy, even though the flushing gallery distance reached 100 m. At present, the storage tank has been stable operation, which could effectively regulate water storage, control runoff pollution and improve the urban environment.
