Summarize the role of lime in wastewater treatment of phosphorus have played what role Summary Lime wastewater treatment of phosphorus have played what role Lime in wastewater phosphorus removal can be used as a separate phosphorus agent, Polyferric sulfate treatment of phosphorus in the role, which is now the most commonly used in wastewater treatment of phosphorus, a good method of phosphorus removal. Polyferric sulfate as a phosphorus removal agent, dissolved in sewage treatment after the formation of multi-core complexes and the occurrence of electric neutralization, network capture flocculation and other functions of the orthophosphate in sewage effluent to form insoluble precipitate, and then by solid Liquid separation method to remove phosphate. At the same time, as acidic polymers, polymeric ferric sulfate consumes alkali in water during the chemical reaction of phosphorus removal. Dosing lime can improve the alkaline water, so that the wastewater to achieve the best range of poly-iron, get better play its role in flocculation, reduce PFS dosage, improve the effect of PFS. Lime in sewage treatment of phosphorus 1, in addition to the above-mentioned role. It itself has the role of chemical precipitation phosphorus removal, the formation of a large number of its own dissolved calcium ions can react with phosphate to generate calcium phosphate precipitate with poor solubility. 2, to remove the role of other metal ions in the water, lime as a pH regulator, can be adjusted by acid and alkali, so that the metal ions in the water to its own sedimentation value to produce precipitation. Calcium hydroxide colloidal material also has the role of adsorption, adsorption of metal substances. 3, to remove impurities such as suspended solids, follow-up polymerization of ferric sulfate to provide better conditions. In addition to producing a colloidal substance with adsorption, this product can neutralize the negatively charged colloidal substances in the water by forming a large amount of positive charges, so that the fine contaminants in water can form precipitates and then be treated by solid-liquid separation . Dosing and adding PFS need to add lime to increase the alkalinity of wastewater and reduce pollutants in water, providing more favorable conditions for subsequent sewage treatment, reducing the cost of medicament and the total cost, and improving the reaction rate and removal rate.
