Overflow pollution control detention tank for combined system
The invention discloses an overflow pollution control detention tank for a combined system. The detention tank comprises an interception ditch and a detention area. The two ends of the interception ditch are provided with a water inlet pipe and a water outlet pipe respectively, an overflow port of the detention area is provided with an overflow grid, a first partition wall is disposed at a water inlet of the detention area, and the detention area is internally provided with a water impeller which is used for keeping silt in rainwater-sewage mixed water suspended and preventing the silt from depositing on a bottom plate of the detention area. The slope of the bottom plate of the detention area is 1%, so that the silt is further prevented from depositing on the bottom plate. A submersible lift pump is arranged in a pump well, a second partition wall is arranged between the detention area and the pump well and used for creating a stable water inlet flow state for the submersible lift pump, and a water inlet hole is formed in the second partition wall. The detention tank has the advantages of being good in silt deposition prevention effect, low in engineering cost, easy to implement and convenient to operate and manage.
本发明公开了一种合流制溢流污染控制的调蓄池，包括截留渠和调蓄区，所述截留渠的两端部分别设置有进水管和出水管，所述调蓄区的溢流口处设置有溢流格栅，所述调蓄区的进水口处设置有第一隔墙，所述调蓄区内设置有推流器，用于保持雨污混合水中的泥砂悬浮，避免泥砂沉积在所述调蓄区的底板上，所述调蓄区的底板坡度为1％，进一步避免泥砂沉积在所述底板上，所述泵井内设置有潜水提升泵，所述调蓄区与泵井之间设置有第二隔墙，用于为所述潜水提升泵创造平稳的进水流态，所述第二隔墙上设置有进水孔洞。本发明具有防泥砂沉积效果好、工程造价低、易于实施和便于运行管理。
