In dry weather, intercepting the sewage along the river drainage port and entering a sewage treatment plant; in rainy days, part of the mixed rain-sewage flow is cut off and enters a sewage treatment plant, and the mixed rain-sewage flow exceeding the cut-off capacity is discharged into surface water.
Traditional vatch basin has slot type, weir formula and groove weir convolution, has following not enough: first, the designed shutoff amount is significantly different from the objectively required shutoff amount. The design intercepting flow is determined by taking measures such as certain research and theoretical calculation, setting different heights of overflow weirs and the like; the flow intercepting amount required objectively is determined according to the actual condition of confluence and mixed flow of each discharge opening, the overflow pollution control requirement and the capacity of the urban sewage treatment system. The difference between the two is large, and once the height of the overflow weir is set, the height of the overflow weir is difficult to adjust. And secondly, draining stagnant water and blocking water.
