缺氧折流板反应器处理苯胺废水的研究

缺氧折流板反应器 (ABR)处理苯胺废水 ,提高了废水的可生化性。采用好氧预挂膜和快速排泥方法进行挂膜 ,缩短了装置启动时间。研究了 p H、温度及容积负荷等因素对反应器处理效果的影响 ,通过改变进水中 BOD与 COD不同浓度 ,测定缺氧折流板反应器改善生化性的能力。试验结果表明 ,装置能稳定运行 ,废水可生化性可提高 2 5 %

Study on Aniline Wastewater Treatment by The Anoxic Baffled Reactor

Anoxic baffled reactor (ABR) is used to treat the wastewater consisting of aniline for improving the wastewater biodegradability.Using the method of aerobic precoating treatment of the biomedium combined with rapid draw-off sludge shortens the reactor start-up time special mention is given here to the factors such as pH,temperature and volume loading experiments with different proportion of BOD and COD show the ability of reactor's improving biodegradability.The results indicate that the reactor can run steadily and that the wastewater biodegradability is improved by 25 percent.
