Case name: coal washing plant wastewater treatment site application case

Pollution problem: sewage PH value is alkaline

Solution: Cationic polyacrylamide is suitable for acidic coal slurry wastewater, and anionic and cationic polyacrylamide are mixed.

Treatment effect: the PH value of wastewater is up to standard.

Coal washing plant is a plant that washes and treats raw coal, and its production process will produce a large amount of wastewater, which contains a large amount of suspended solids, coal sludge and other organic matter.

Coal washing plant wastewater treatment process can be roughly divided into: water treatment system pretreatment - precipitation treatment - sludge treatment - reuse after filtration

Pre-treatment of water treatment system: first of all, we need to pre-treat the wastewater, mainly including filtration, sedimentation and adjustment of PH value.

Precipitation treatment: after pretreatment of wastewater into the sedimentation tank for treatment, in this process we need to use the polyacrylamide, the suspended particles in the wastewater will be precipitated at the bottom of the wastewater.

Sludge dewatering: After precipitation treatment, the sludge formed needs to be treated. In this process link, we add polyacrylamide in the sludge to temper the sludge, and then through the high speed rotation of the centrifuge, the water in the sludge can be separated out to form mud cake.
