污水可生化性及其影响因素研究

Research on the Biodegradation of Wastewater and Its Influence Factors

以自行设计的生化呼吸线测定装置研究了印染污水的可生化性,该装置通过反应体系的溶解氧浓度跟踪生物降解过程。采用本文设计的模拟污水处理装置探讨了污泥驯化时间、污水投加量等对污水可生化性的影响。测定了污水经可生化性调控后的处理效果。结果表明,生化呼吸线法判断污水处理体系的可生化性是1种可靠易行的方法,提高体系的可生化性是增加污水处理效果的关键因素。

The biodegradation of wastewater in textile printing and dyeing has been studied with self-made equipment. The influence factors such as the domestication time of sludge, the amount of wastewater etc. were tested and optimized. The results indicated that biodegradation of sewage and the relative oxygen consumption of the system were remarkably improved when the domestication time was increased. This experiment proves that biodegradation is very important to the increase of the effect of wastewater treatment. The relative oxygen consumption method is better for the assess ment of the biodegradation of wastewater.
