Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a sewage treatment device for groundwater restoration projects. Background Art

[0002] Groundwater is a precious freshwater resource for human beings. When repairing groundwater, the contaminated groundwater is pumped to the pre-treatment pool and mixed with the repair liquid, and then the groundwater is discharged in the pool.

First, close the drainage pipe, then climb to the top of the reactor through the iron ladder, open the drainage pipe, and according to the volume of the reactor, quantitatively add chemical repair agents to the kettle body through the drainage pipe, and then connect the extracted contaminated groundwater outlet pipe to the drainage pipe. When the kettle body is filled with contaminated groundwater, start the motor. As the motor rotates, driven by the stirring shaft, the stirring paddle rotates at high speed, and the chemical repair agent is evenly dispersed in the water and reacts quickly and fully. When the stirring reaction reaches a certain time, open the drainage pipe, discharge the repaired groundwater that meets the standards, and then enter the next batch of contaminated groundwater repair procedures.
