This review surveys the implementation of anaerobic membrane bioreactors in municipal wastewater treatment at ambient temperature. High chemical oxygen demand (COD) removal efficiencies and methane conversion rates were achieved under various conditions, while also achieving a low sludge yield of 0.04–0.09 g volatile suspended solids (VSS)/g COD. A survey of energy demands for pilot-scale anaerobic membrane bioreactors showed that they could be energy neutral or even positive, even though high energy (0.08–0.35 kWh/m3) is required to clear membrane fouling. Thus, the use of anaerobic membrane bioreactors in municipal wastewater treatment at ambient temperature is very promising. However, some challenges such as membrane fouling control, methane in effluent, low COD/SO42−-S ratio, and deficiencies in alkalinity should be addressed, especially the latter. Future research perspectives relating to the challenges and further research are proposed.

厌氧膜生物反应器在环境温度下城市污水处理中的应用:成就,挑战和观点综述

这篇综述调查了厌氧膜生物反应器在环境温度下市政污水处理中的实施情况。在各种条件下均实现了较高的化学需氧量(COD)去除效率和甲烷转化率,同时还实现了0.04-0.09 g挥发性悬浮固体(VSS)/ g COD的低污泥产率。对中试规模厌氧膜生物反应器的能量需求进行的调查显示,即使需要高能(0.08–0.35 kWh / m 3)来清除膜污染,它们也可能是中性的,甚至是正能量。因此,厌氧膜生物反应器在环境温度下的市政废水处理中的应用非常有前途。但是,存在一些挑战,例如膜污染控制,废水中的甲烷,低COD / SO 4 2--S比和碱度不足应予以解决,尤其是后者。提出了与挑战有关的未来研究观点和进一步的研究。
