混凝实验用于垃圾渗滤液处理应用研究

摘要

垃圾渗滤液是一种成分复杂、有机物浓度高、污染严重的废水.本文针对江苏镇江某垃圾填埋场的渗滤液，探索PAC和PFS两种混凝药剂进行混凝对该废液的处理效果，实验研究发现：在渗滤液酸碱平衡体系被打破的点（pH为4.5左右和11.5左右时），混凝效果最好；PFS的混凝效果要优于PAC的混凝效果；在PFS投加量为2200 mg/L，PAM投加量为40 mg/L时，可获得50%左右的COD浓度去除率.%The garbage leachate is a kind of complicated composition, high concentration of organic matter, waste water pollution. Aiming at a landfill leachate in Zhenjiang City of Jiangsu Province to explore the PAC and PFS coagulation reagent for coagulation of the wastewater treatment effect, the experimental study found that the leachate pH balance system break point (when pH is about 4.5 and 4.5), the coagulation effect is best; PFS coagulation effect is superior to PAC coagulation effect; In PFS dosing quantity is 2200 mg/L, PAM dosing amount to 40 mg/L, can obtain 50% removal rate of COD concentration.
