Description

Sewage treatment equipment with desilting function Technical Field The utility model belongs to the technical field of sewage treatment equipment, and particularly relates to sewage treatment equipment with a dredging function. Background The sedimentation link in sewage treatment usually uses a sedimentation tank to enable suspended solids to sink by gravity and supernatant to be discharged, and then the suspended solids are matched with subsequent procedures to finish standard reaching treatment. The engineering practice is that the sedimentation tank is provided with a water inlet pipeline, a water outlet pipeline and a basic valve, the sedimentation tank is used for collecting sludge by a low-lying area or a sludge collecting tank at the bottom of the sedimentation tank, the sedimentation tank is stopped, emptied or changed to bypass after running for a period of time, and then the sludge is removed by a manual dredging, sludge suction pump discharging or external conveying device. The scheme has simple structure, but often has the realistic constraints of long-time shutdown, repeated opening and closing of the valve, easy diffusion of secondary pollution and the like in the field. The problem of the prior art is that the partial partition and automatic sludge discharge cooperative structure facing the 'no-emptying' working condition is lacking, when dredging is attempted to be carried out while liquid is still maintained in the tank, the hydraulic disturbance formed by sewage in the tank can cause floating matters and bottom sludge to be rolled up again, and the floating matters and the bottom sludge can only be turned over to carry out low-efficiency manual intermittent dredging after shutdown and emptying, so that dredging efficiency is lower and shutdown time is longer. Disclosure of utility model Aiming at the problems, the utility model aims to provide the sewage treatment equipment with the dredging function, which does not need to empty sewage in the sedimentation tank before dredging, combines the function of automatically discharging and dredging, effectively reduces the downtime required by dredging and improves the dredging efficiency of the sedimentation tank.
