Background

The inclined plate sedimentation tank is a shallow sedimentation tank arranged between every two parallel inclined plates. The treated water (or waste water) and the settled sludge are moved and separated from each other in the shallow layer of the sediment. The separation method can be divided into three different separation modes of cocurrent flow, incongruous flow and lateral flow according to the force of mutual movement; the inclined plate sedimentation tank utilizes the principle of 'shallow layer sedimentation', shortens the sedimentation distance of particles, thereby shortening the sedimentation time, increasing the sedimentation area of the sedimentation tank and improving the treatment efficiency. The waste water terminal inclined plate sedimentation tank is an extremely important ring of waste water treatment equipment and is related to whether the discharged waste water reaches the standard or not.

At present, a PH probe used by an inclined plate sedimentation tank adopts fixed position measurement, the PH probe cannot measure when the liquid level is reduced when the sedimentation wastewater is discharged, and the measurement can be continued when the water level is increased to overflow again; moreover, the existing PH equipment can only monitor the PH value of the wastewater and can not reprocess unqualified water quality; in addition, if the water outlet is blocked, the wastewater overflows to pollute the environment.
