| 摘 要： | 采用活性炭吸附预处理后的莠去津农药废水中的有机物,研究了活性炭种类、溶液pH值、盐含量对吸附的影响,测定了吸附等温线,并探讨了活性炭的再生性能.结果发现:pH值小于3时粉状木质活性炭对农药废水的吸附效果最好;废水中的盐含量越高,越有利于吸附;Freundlich模型比Langmuir模型能更好地拟合吸附等温线,pH值为3时的最大吸附量为250 mg/g.碱液可以将吸附在活性炭上的有机物解吸下来,再生后活性炭的吸附量可达到新鲜活性炭的98%以上.

| Abstract: | The effect of various activated carbon, pH value and salt content on the adsorption of organics from pretreated atrazine wastewater is investigated. Adsorption isotherm and regeneration properties of activated carbon are also studied. The results show that powder wooden activated carbon favors the removal of pesticide wastewater at pH 〈 3. The adsorption capacity of activated carbon increases with the increase of salt content. The adsorption isotherm data fit with the Freundlich model better than Langmuir model, with the maximum adsorption capacity of 250 mg/g at pH value of 3. Organics adsorbed on activated carbon can be removed in alkali solution, and higher than 98% of adsorption capacity is regenerated in comparison to fresh activated carbon. |
