前置及后置化学除磷在工业废水处理中的应用

Application of Preposition and Postposition Chemical Phosphorus Removal in Industrial Wastewater Treatment

实际工程应用表明:将前置及后置协同除磷技术用于工业废水处理,前置化学除磷可降低生化处理的有机负荷;后置化学除磷可改善生化出水的沉淀性及钙盐与废水中磷酸盐的结合,保证出水TP≤0.5mg/L。

The practice engineering application indicates: The technology of preposition and postposition synergistic phosphorus removal treats the industrial wastewater. The preposition chemical phosphorus removal can reduce the organic load of the biochemical treatment; The postposition chemical phosphorus removal can improve the deposition of biochemical water and the combination of calcium salt and the phosphate in the wastewater, and ensure the water outlet is at TP≤0.5mg/L.
