Use of special polyacrylamide for steel mills_anionic polyacrylamide
Anionic polyacrylamide is used as a flocculant in the treatment of wastewater from steel plants to treat wastewater from steel plants. It is also called polyacrylamide for steel plants. The effect is very significant. Anionic polyacrylamide for suspended particles, positively charged high concentration particles, neutral or alkaline wastewater, iron and steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater, etc., sewage treatment effect is good, mainly used for industrial wastewater treatment.
Because the main pollutants in steel mill wastewater are a large number of iron oxide scale and lubricants of different particle sizes, this kind of wastewater has the characteristics of large amount of water after use and high water temperature. Therefore, anionic polyacrylamide is usually used in the treatment of such sewage. When using anionic polyacrylamide to treat steel mill wastewater, it is necessary to pay attention to the correct use method.
Anionic polyacrylamide in the use of steel plant wastewater treatment:
1. When using, please prepare an aqueous solution with a concentration of 0.01. It is recommended to use neutral salt-free water.
2. When dissolving, sprinkle the anionic polyacrylamide product evenly into the stirring water, and control the stirring speed at 100~300rpm. Proper heating can accelerate the dissolution.
3. Adjust the pH value of the liquid to be treated so that the anionic polyacrylamide product can fully function.
4. When adding the product solution, the mixing with the liquid to be treated should be accelerated. After the floc appears, the stirring speed should be reduced to promote the growth of the floc and accelerate the settlement.
Polyacrylamide for wastewater treatment in steel mills, special polyacrylamide for steel mills Before the dust removal wastewater enters the sedimentation tank, it first passes through coarse particle separation equipment to remove large particles of suspended impurities, and then enters the sedimentation tank, add a PH regulator in the open channel of the sedimentation tank, and add polyacrylamide for wastewater treatment in the steelmaking plant to achieve co-flocculation and precipitation of suspension and scale in the sedimentation tank and in the sedimentation tank wastewater. In this way, the problem of wastewater purification and the problem of water stability are solved, and a better treatment effect is achieved. The suspended solids in the water are flocculated into small flocs; when anionic polyacrylamide is added to the steel plant in the sewage for sewage treatment, the steel plant uses the flocculant polyacrylamide to make the flocculant have a stronger binding force and make it settle. Through production practice, it is considered that the effect of adding PAC and polyacrylamide is more ideal.
