摘要:

我国污水处理厂对污废水进行生物处理时应用最广泛的工艺是活性污泥法。但该工艺存在占地面积大的问题,而随着城市化进程的加快,土地使用越来越受到限制。学者们对新型污水处理技术进行了研究。连续流好氧颗粒污泥技术被认为是最具潜力的污水生物处理技术之一。简要论述了连续流好氧颗粒污泥的培养方法与形成机制,重点综述了连续流系统中,水力剪切力、HRT、微生物饱食-饥饿期、反应器构型及运行方式等因素对污泥颗粒化及稳定性的影响,介绍了该技术对氯化苄生产废水、实际生活污水、黄连素废水、乳制品废水等污废水的处理效果,并对该技术目前存在的技术差距进行讨论,最后指出连续流好氧颗粒污泥技术未来的研究重点。

Abstract:

The most widely used process for biological treatment in wastewater treatment plants in China is activated sludge method. However, it has the problem of occupying large site area. With the accelerated urbanization, land use is increasingly restricted. Researchers have investigated new wastewater treatment technologies. Continuous flow aerobic granular sludge technology is considered one of the most promising biological treatment technologies for wastewater. The cultivation method and formation mechanism of continuous flow aerobic granular sludge were briefly discussed, focusing on the effects of factors such as hydraulic stress, HRT, microbial satiation-starvation period, reactor configuration and operation mode on sludge granulation and stability in continuous flow systems. The treatment effects of the technology on benzyl chloride wastewater, domestic wastewater, berberine wastewater and dairy wastewater were presented, and the current technical gaps of the technology were discussed. Finally, the future research focus of continuous flow aerobic granular sludge technology was proposed.

Key words: continuous flow, aerobic granular sludge, cultivation method, wastewater treatment
