| 摘 要： | 为了实现净水厂污泥的资源化利用,对净水厂污泥的磷吸附特性进行了研究。通过吸附试验考察了对照土样和净水厂污泥的磷吸附能力,研究了温度、溶液初始pH值和初始浓度对净水厂污泥磷吸附的影响。结果表明,对照土样和净水厂污泥对磷的吸附都符合Langmuir吸附等温方程,净水厂污泥的磷吸附容量是对照土样的17倍;净水厂污泥对水中磷的吸附速率随温度的升高增大,随pH的增高降低,随初始浓度的升高增大;净水厂污泥对磷的吸附过程可以采用一级动力学方程描述;净水厂污泥具有作为污水除磷材料的巨大潜力。

| Abstract: | Experiments were done to investigate phosphorus adsorption characteristics of waterworks sludge.The phosphorus adsorption of waterworks sludge and control samples were studied and compared,the impact of temperature,initial pH and phosphorus concentration on phosphorus adsorption was investigated.Results indicated that the Langmuir equation could describe phosphorus adsorption of waterworks sludge and control samples,with phosphorus adsorption capacity of waterworks sludge 17 times higher than the control sa... |
