摘要
主要研究了KH2PO4溶液在矿化垃圾中的吸附性能,静态和动态试验研究表明在静态试验条件下,初始浓度越高,固液比越小,矿化垃圾吸附磷量越多;pH对磷吸附性能具有较大的影响,当pH在8左右时,矿化垃圾吸磷量达到最大吸附量。在动态实验条件下,湿干比减小,配水速率减小,都有利于矿化垃圾除磷率的增加,当初始溶液的磷质量浓度为50mg/L时,矿化垃圾有最佳除磷率。
Laboratory batch adsorption experiments were conducted to evaluate the adsorption capacity ol me aged-refuse. The results of static experiment show that the adsorption capacity increased with the the initial concen trations of KH2PO4 and decrease with solid/liquid ratio. The pH value have a great effect on the adsorption capacity and it get the maximum at the pH value of 8. The results of dynamic experiment show that the adsorption capacity increase with decrease of the hydraulic load and wet/dry ratios, it gets the maximum removal rate at the concentration of 50 mg/L.
