酒店废水中LAS的强化生物处理研究

Study on the enhanced biological treatment of LAS in hotel wastewater

本文主要研究在生长有成熟生物膜的填料上强化LAS生物降解作用,提高生物接触氧化系统的LAS降解能力。试验结果表明,经强化LAS降解作用的二段生物接触氧化系统LAS去除率可由65％提高到80％以上。其中第二段接触氧化的LAS去除率高于第一段接触氧化。

This paper shows the study on the enhanced biodegradation of LAS on filler with mature bio-membrane so as to increase capability of LAS degradation of biological contact oxidation system. The results show that removal rate of LAS can be increased from 65 % to 80 % through the two-step enhanced biological contact oxidation system. The removal rate of LAS at the second step is higher than that at the first step.
