Surfacing type floating present sundries outflow control unit for drainage

摘要

Topic The storm outfall chamber which diverts the rainwater and the sewage in the drainage in order effluent treatment the confluence type sewage work, (diverted water man hole) oily amount inside and the surfacing type floating present sundries outflow control unit for the drainage which controls the outflow of the floating present sundries are offered.SolutionsOn the diverted water weir in the diverted water man hole of the confluence type sewage work and on the today sundries removal device, it follows to water level, it captures and it installs the control board containment oily amount and the floating present sundries. In addition, because it has surfaced to the surface moisture where the surfacing type floating present sundries outflow control unit for the drainage velocity of flow is slowest, loss with respect to the water reason which is generated can be smallest, hold down also the influence to the secondary disaster and the like with water level rise to the utmost.
