摘要

通过实验室小试，研究了一体式膜生物反应器（MBR）对微污染湖水中的微量2

4-二氯酚（2

4-DCP）的去除效果。64 d的连续试验证实，当进水2

4-DCP浓度在2～200 μg·L-1时，MBR对2

4-DCP的平均去除率达936%。出水2

4-DCP浓度平均为428 μg·L-1，满足《城市供水水质标准》的要求。同时采用间歇试验对MBR去除2

4-DCP的机理进行了研究，证实生物作用在2

4-DCP的去除中起主要作用，MBR对2

4-DCP的去除符合零级动力学过程，降解速率常数为106 μg·L-1·min-1。此外，试验证实MBR对DCP的去除是基于二级基质原理，而向反应器内投加葡萄糖并不能促进MBR对2

4-DCP的去除。

Abstract

In this bench-scale test

a membrane bioreactor (MBR) was investigated for the removal of trace 2

4-dichlorophenol (2

4-DCP) from surface water with slight pollution.Sixty four days of continuous test proved that when the concentration of 2

4-DCP in the raw water fluctuated between 2—200 μg·L-1

averaged removal efficiency reached 936%And the averaged 2

4-DCP concentration in the treated water was 428 μg·L-1

which could meet the Sanitary Standard for Drinking Water Quality issued by the Ministry of HealthAt the same time

intermittent tests were carried out to study the 2

4-DCP removal mechanisms in MBRIt was concluded that biological degradation played a major role in 2

4-DCP removal by MBR It was found that biodegradation of 2

4-DCP followed zero-order kinetics with a rate constant of 106 μg·L-1·min-1Besides

it was confirmed that secondary substrate utilization was the mechanism that allowed effective biodegradation of 2

4-DCP by MBR

however dosing glucose into the raw water could not improve the biodegradation.
