| 摘 要： | 采用合成水化硅酸钙进行污水除磷试验,以模拟污水为研究对象,考察了接触时间、Ca2+浓度、初始pH值、干扰离子等因素对除磷效果的影响,在利用水化硅酸钙回收实际污水中磷的试验发现,在处理8h后除磷量达到101 mg/g,折合P2O5含量超过常用的水溶性磷肥过磷酸钙,且产物经酸处理后将快速释磷,在1h后磷释放率接近100％,...

| Abstract: | Taking simulation wastewater as the research object,a test on phosphorus removal from waste-water by synthesized calcium silicate hydrate was carried out,and the influences of contact time,Ca2+ concentra-tion,initial pH value,interfering ion and some other factors on phosphorus removal were investigated.The results of the test on phosphorus recovery from actual wastewater by calcium silicate hydrate showed that,after 8 hours of reaction,the amount of phosphorus recovery reached 101 mg/g;the phosphorus conte... |
