Water treatment of hydrated lime powder
Hydrated lime powder is not a polymer in the water treatment agents, but it is used more widely in practical applications. What are the water treatment effects of hydrated lime powder? Then, the following is to understand the water treatment effects of hydrated lime powder!
1. Application of alkaline regulation of wastewater In the treatment of wastewater with hydrated lime powder, alkali regulation of acidic wastewater is mainly based on the addition of alkaline agents such as slaked lime and cartel. Most of the wastewater should be neutralized first, and the pH value of the water should meet the requirements of subsequent treatment. Sulfuric acid, hydrochloric acid and other acidic agents are the main neutralization agents of hydrated lime powder in wastewater. Of course, if slaked lime is allowed, the two effluents can be mixed for neutralization.
2. Wastewater coagulation and adsorption application The hydrated lime powder has certain adsorption effect on the suspended matter in water. It is difficult to play a role at the same time, making its comprehensive effect stronger. Hydrated lime and diatomite are the mixed agents. These materials have common characteristics, and their flocculation and adsorption have good removal effect on phosphorus, fluorine and COD in water.
3, short circuit APP application Hydrated lime powder in wastewater treatment, compared with other flocculants, hydrated lime is more suitable to destroy the complex in wastewater, improve the treatment rate of complex wastewater, destroy the combination of amino sulfonic acid and metal ions, control the catalytic decomposition reaction of metal ions with hydrogen peroxide and hypochlorite.
4. Heavy metal treatment application With the use of hydrated lime powder on heavy metals in water, most of the heavy metals suspended in water can eliminate the repulsive force and form precipitation through its strong adsorption. It is then treated by solid-liquid separation.
5. Other apps Hydrated lime powder has the function of reducing biochemical oxygen demand and killing bacteria and pathogens in water, so it is also commonly used in environmental disinfection and sterilization. It can also remove ammonia nitrogen in the wastewater and destabilize and demulsify the emulsion wastewater.
Using hydrated lime powder to treat pollutants, hydrated lime powder reaction at the same time produce a lot of heat to precipitate mud dry, greatly reduce the whole treatment cost; The invention has the advantages of good fruit, wide source, low cost, and no new pollutants will be brought when the waste water is treated. The technological process of the invention has the advantages of environmental protection, small energy consumption, and easy to realize industrial scale production. The invention improves the lead content by extraction and uses fire metallurgy to achieve high metal lead purity. Used for pH regulation of acidic wastewater, the heavy metal effect of wastewater remover with high alkalinity and low treatment cost is due to liquid alkali. The water treatment plant uses slaker powder to remove most of the phosphate and heavy metals in the wastewater. It is widely used in the wastewater treatment of electroplating, printing and dyeing, chemical industry and acid industry. In addition to other advantages, it can also improve the taste, smell and color of the water and remove the plankton, thus eliminating the turbidity.
In addition, manganese, fluoride, organic tannins are also removed from the above silica. The role of hydrated lime powder is clear and we can make better use of its role in industrial applications to help our industrial production and other needs. The above introduction is the water treatment of hydrated lime powder, if you need to know more, please feel free to contact us!
