一种适合农村的污水处理技术-厌氧折流板反应器

Rural Wastewater Treatment Technology:Anaerobic Baffled Reactor

在经济技术水平欠发达的农村,寻找可行的废水处理解决方案是一项挑战。城市好氧污水处理厂的建设,运营和维护成本高,并不适合农村。厌氧折流板反应器(ABR)具有结构简单、易于制造、固体生物截留能力强、污泥产量低、抗冲击负荷能力高、对有机物处理效果好、运行成本低等特点,非常适合农村分散污水处理。介绍了ABR反应器的发展与改进,综述了温度、pH、进水有机物浓度、水力停留时间、反应器启动、冲击负荷等因素对ABR处理效果的影响,分析了ABR反应器适宜的污水浓度范围以及在农村应用的可行性,介绍了基于ABR的组合工艺。

As economic and technological levels are underdeveloped in rural areas,finding a viable wastewater treatment solution is a challenge.The construction,operation and maintenance costs of urban aerobic wastewater treatment plants are high and not suitable for rural areas.Anaerobic baffled reactor(ABR)has the characteristic of simple structural design,strong solid biological retention capacity,low sludge yield,high impact resistance,good organic matter treatment and low operating costs,very suitable for rural decentralized wastewater treatment.The development and improvement of ABR reactor in recent years are introduced.The influence of temperature,pH,influent organic matter concentration,hydraulic retention time,reactor start-up,shock load and other factors on the ABR treatment efficiency are summarized.The suitable sewage concentration range of the ABR reactor and the feasibility of its application in rural areas are analyzed,and the combined process based on ABR is introduced.
