利用钙盐对模拟的厌氧养猪废水进行除磷研究,找出磷酸钙形成沉淀所需的适宜钙磷比.先后进行批次和连续流试验,比较生石灰与熟石灰的除磷效果以及石灰与钙盐在除磷应用上的区别,优化选出最佳除磷试剂.实验表明:磷酸钙沉淀法能有效去除厌氧养猪废水中的磷元素,同时降低废水的色度和浊度.

Phosphorus removal from simulated anaerobically-treated swine wastewater was studied by calcium salt precipitation method,and the optimum ratio of suitable calcium to phosphorus was obtained.Simultaneously,batch and continuous flow tests were carried out to compare the efficiency of quicklime and slaked lime,and the difference between lime and calcium salt in order to optimize,the reagent for phosphorus removal.The reushs showed that the precipitation method can effectively remove phosphorus from swine wastewater,meanwhile,reduce lower the color and turbidity.
