摘要
在实验室保证厌氧条件下,通过恒温摇床试验,研究焦化废水中芳烃类物质苯胺、萘和茚的降解去除规律,同时对这三种芳烃类有机物在水相和泥相中的含量进行了测定。研究结果表明:苯胺的厌氧去除主要通过生物降解,但微生物需要一个适应过程;萘和茚的厌氧去除途径是吸附在污泥上进行降解,萘经过48 h可降解完全,茚的吸附属物理吸附,是可逆的。
The degradation and removal of aromatic hydrocarbon aniline, naphthalene and indene in the coking plant wastewater under anaerobic conditions were studied by constant temperature flask-shaking tests in the lab. The concentration of aniline, naphthalene and indene in supernatant, sludge under the anaerobic conditions was analyzed. The results indicate that aniline was mainly removed through biodegradation, however, the microorganism will need some time to adjust to its new environment. The removal path of naphthalene and indene was absorption-degradatio can be biodegraded in 48 h, and the absorption of indene on the sludge was a physi reversible.
