粉末活性炭强化活性污泥处理苯胺废水的实验研究

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 1g/ 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% .
