摘要
苯胺废水多来源于化工制药行业,大量排入环境中的含苯胺废水,不仅对环境造成严重的危害,而且对人类的饮水造成了严重的威胁。苯胺废水的传统方法主要有物理、化学、生物等方法。本文利用粉末活性炭强化活性污泥法(PAC-AS)处理难降解苯胺废水。通过高效液相色谱法对废水中苯胺含量的测定,研究苯胺的去除率。实验过程主要考察了活性炭量、反应时间对苯胺降解的研究。结果表明:2 g PAC的初始投量下(以反应器体积计1 g/L),污泥沉降比为30%,苯胺初始浓度为100 mg/L,24 h后对苯胺的去除率达到84%,反应48 h后对苯胺的去除率达到96%。
Aniline wastewater and more from the chemical and pharmaceutical industry, a large number into the environment of waste water containing aniline, not only causing serious harm to the environment, but also for human drinking water caused a serious threat. Traditional aniline wastewater main physical, chemical, biological and other methods. In this paper, the use of powdered activated carbon intensified activated sludge process （ PAC - AS） aniline wastewater treatment refractory. By HPLC wastewater aniline content Aniline removal. Experimental procedure mainly on the amount of active carbon, the reaction time of aniline degradation. The results showed that： 2 g PAC initial dosage （of the reactor volume lg/L）, sludge settlement ratio is 30% ,aniline initial concentration of 100 mg/L,24 h after aniline removal rate of 84% ,the reaction 48h after aniline removal rate of 96%.
