| 摘 要： | 利用改性煤矸石预处理垃圾渗沥液，考察了改性煤矸石粒径、投加量及吸附反应时间对废水处理效果的影响。试验结果表明，利用改性煤矸石预处理垃圾渗沥液的最佳试验条件为：在原水COD为6096mg／L，氨氮为31．7mg／L，浊度为19．9NTU时，投加0．1245mm改性煤矸石3g，与50mL废水混合，振荡吸附120min，处理后出水COD为1466mg／L，氨氮为17．2mg／L．浊度为8．1NTU，对COD、氨氮、浊度的去除率分别可达到75．95％、45．74％和59．19％。该项研究为改性煤矸石作为水处理吸附剂在垃圾渗沥液及其他高浓度难降解废水处理中的应用提供了理论依据，同时也为垃圾渗沥液的处理提供一种途径。

| Abstract: | Investigated the effect of particle size, dosage of modified coal gangue and adsorption time on landfill leachate treatment. The results indicated that the removal rates could reach 75.95%, 45.74% and 59.19% for COD, NH3-N and turbidity respectively when the influent concentration of COD, NH3-N and turbidity were 6096mg/L, 31.7mg/L and 19.9NTU, and the effluent concentration of COD, NH3-N and turbidity were 1466mg/ L 17.2mg/L and 8. INTU respectively under the condition of 3g modified coal gangue of 120 mesh mixed with 50mL wastewater and sampling after 120min. Provided a theoretical reference for modified coal gangue used in landfill leachate treatment. |
