Reclaimed water recycling system for multi-edging and polishing line sewage sharing type treatment

Abstract

The invention provides a reclaimed water recycling system for multi-edging and polishing line sewage sharing type treatment. The system is arranged beside water production equipment. The system sequentially comprises coarse and fine particle rapid separation equipment, coagulation-aiding automatic dosing equipment, high-level tank sewage precipitation equipment, concentration-controllable slurry recycling equipment and clear water recycling equipment, the water production equipment discharges sewage with particles into the coarse and fine particle rapid separation equipment to separate out coarse particles; after the coarse particles are separated, the sewage is introduced into the coagulation-aiding automatic dosing equipment, and a PAC coagulant and a PAM coagulant aid with certain concentrations are added; then the sewage is pumped into the high-level tank sewage precipitation equipment to carry out continuous low-flow-rate dynamic precipitation, clear water and mud-containing slurry are separated out, the mud-containing slurry is introduced into the concentration-controllable slurry recycling equipment to prepare mud or into a slurry preparation tank for later use, and the clear water is introduced into the water production equipment through the clear water recycling equipment and is recycled. The system has the advantages of small occupied area, proper circulating water storage amount, small evaporation loss, low equipment cost and the like.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a multi-grinding and polishing line sewage common treatment reclaimed water reuse system. Background technique [0002] Architectural ceramics enterprises will produce a large amount of muddy sewage in the production process of ceramic tile edge grinding and wet polishing. If it is discharged directly, it will cause environmental pollution and waste a lot of water resources and usable mud. It must be treated. Reclaimed water and sludge can be recycled. [0003] The existing muddy sewage reuse treatment system in the building ceramics industry adopts the advection pool sedimentation process, which has the following problems and shortcomings: [0004] 1. The advection pool sedimentation treatment process is adopted, and multiple advection pools are set up, which covers a large area and requires a lot of management workload. [0005] 2. Precipitation by physical method, l...

AI Technical Summary

Problems solved by technology

[0004] 1. The advection pool sedimentation treatment process is adopted, and multiple advection pools are set up, which covers a large area and has a large management workload

[0005] 2. Precipitation by physical method, long precipitation time, huge circulating water stock, large evaporation loss

[0006] 3. It is difficult to clean up the sediment, and the area to be cleaned is large; the water content of the material after dehydration is high, and the treatment cost is high
