Construction wastewater reutilization system

Abstract

The invention relates to a construction wastewater reutilization system, which comprises a first sedimentation tank, a second sedimentation tank and a water storage tank. The first sedimentation tankis communicated with a construction drainage ditch, the first sedimentation tank and the second sedimentation tank are communicated by a water inlet pipe, the water inlet pipe is arranged inside the first sedimentation tank to form an overflow pipe structure, the second sedimentation tank is internally provided with a vertical flow guide pipe, and the water outlet end of the water inlet pipe is located inside the flow guide pipe, a reflection plate is disposed in the flow guide pipe, the second sedimentation tank and the water storage tank are communicated through a drain pipe, the bottom of the second sedimentation tank is equipped with a sewage discharge port, a sludge discharge pipe is installed inside the second sedimentation tank, the lower port of the sludge discharge pipe is disposed at the bottom of the second sedimentation tank, the sludge discharge port of the sludge discharge pipe is lower than the drain pipe, and the silt at the bottom of the second sedimentation tank can be discharged by hydrostatic pressure difference between the drain pipe and the sludge discharge port of the sludge discharge pipe. The construction wastewater reutilization system provided by the invention can realize efficient reutilization of construction wastewater, reduces the floor space and reduces the cost.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment, in particular to a construction waste water reuse system. Background technique [0002] In recent years, with the rapid development of construction engineering and green construction, the reuse of wastewater in the construction process has attracted more and more attention. At present, three-stage sedimentation tanks are mainly used to achieve the purpose of recycling construction wastewater, but this method has disadvantages such as large area, low utilization efficiency, long wastewater sedimentation time, and inability to efficiently recycle. Especially for construction projects with large building area and large water consumption, there are obvious disadvantages in its use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a construction wastewater reuse system to realize efficient reuse of construction wastewater. ...
