Today, Xiaobian will introduce you: aluminum profiles manufacturers aluminum profiles wastewater and sewage mainly contain various metal ions and suspended solids, most of the manufacturers are using the neutralization adjustment and coagulation precipitation process. The wastewater produced by the aluminum profile is discharged from the workshop and flows into the neutralizing and regulating tank, which is equipped with air mixing to balance the water quality.
After the wastewater is balanced by the water quality and amount of water in the regulating pool, the alkali is added to adjust the pH value, so that it is kept between 6 and 9, and then the pump is used to pump it and send it to the sedimentation tank, at this time we also want to add some flocculant in it. Because the metal ion in the wastewater reacts with the alkali to form hydroxide, it will form a relatively large particle alum under the action of flocculant, and it will settle rapidly under the action of gravity, and the half clear liquid of the sedimentation tank can be directly discharged. The sludge from the sedimentation tank is concentrated in the sludge tank and pumped into the plate and frame filter press for dewatering and then used for sanitary landfill or comprehensive utilization.
The above is the process and steps for most aluminum profile manufacturers to treat wastewater and sewage.
