Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to precipitation equipment for treating coal-containing wastewater. Background Art

[0002] A coal-containing wastewater treatment device with announcement number CN215654232U relates to the field of water treatment and includes a sedimentation tank, wherein a placement plate is fixedly connected to the left side of the upper surface of the sedimentation tank. The utility model provides an overflow port, an electric push rod, and a baffle plate. By controlling the electric push rod to retract and drive the baffle plate to move upward, the overflow port is opened, thereby allowing the upper layer of clean water that has been settled in the sedimentation tank to flow out from the overflow port. The overflow port is provided to prevent turbid water containing coal slag in the lower layer of the sedimentation tank from flowing into the filter tank, thereby preventing excessive coal slag from entering the filter tank, affecting the sedimentation effect and reducing the treatment effect of the device on the coal-containing wastewater. This solves the problem that existing coal-containing wastewater treatment equipment is inconvenient to clean the deposited coal slag during use. At the same time, when the existing coal-containing wastewater treatment equipment is discharged after sedimentation, the coal slag deposited at the bottom is easily caused to flow out along with the clean water, thereby reducing the sedimentation effect.

[0003] The above-mentioned coal-containing wastewater treatment equipment, when working to precipitate solids, is filled with precipitated solids in the mixed solution. Simply by letting it stand naturally, the time required for the solids and solution to separate is increased, which prolongs the time required for wastewater treatment and reduces work efficiency.
