摘要
实验以洗车废水为研究对象,研究了聚丙烯腈活性炭纤维(PAN-ACF)去除水中LAS的效果,考察了PAN-ACF的用量、时间、温度以及pH对吸附效果的影响。模拟废水和实际洗车废水的实验研究表明:当废水中LAS浓度为10 mg/L时,在处理最佳时间为5 min、最佳用量为0.5 g/L、常温弱酸性的条件下,LAS的去除率能达到92%以上。此外PAN-ACF对废水中的CODcr及NH3-N也能有效地去除,用NaOH溶液再生后对LAS吸附性更好。
The article investigated the removal of LAS from Car - washing wastewater using PAN - ACF as adsorbent. And it indicates that adsorption effect which influenced by PAN - ACF dosages, adsorption time, temperature and pH. The experiment results of simulated wastewater and real wastewater indicate as follows：Under the condition of the weak acidity, normal temperature, the 5 min optimum time and the 0. 5 g/L optimum dosages, the removal rate for LAS was more than 92% with the LAS con- centration of 10 mg/L. In addition, PAN - ACF also can remove CODe, and NH3 - N in Car - washing wastewater effectively, and the better removal rate can be achieved after regeneration with NaOH solution.
