Abstract：
Treatment of high-strength wastewater is critical for the aquatic environment and receiving water bodies around the globe. Untreated or partially treated high-strength wastewater may cause severe damage to the existing water bodies. Various high-rate anaerobic bioreactors have been developed in the last decades for treating high-strength wastewater. High-rate anaerobic bioreactors are effective in treating industrial wastewater and provide energy in the form of methane as well. However, the physical or chemical properties of high-strength industrial wastewater, sometimes, disrupt the functioning of a high-rate anaerobic bioreactor. For example, the disintegration of granular sludge in up flow anaerobic sludge blanket reactor or membrane blocking in an anaerobic membrane bioreactor are the results of a high-strength wastewater treatment which hamper the proper functioning and may harm the wastewater treatment plant economically. Biochar, if added to these bioreactors, may help to alleviate the ill-functioning of high-rate anaerobic bioreactors. The primary mechanisms by biochar work in these bioreactors are direct interspecies electron transfer, microbial immobilization, or gene level alternations in microbial structure. The present article explores and reviews the recent application of biochar in a high-rate anaerobic bioreactor treating high-strength industrial wastewater.
摘要：
高浓度废水的处理对于水环境和全球水体的接收至关重要。未经处理或部分处理的高强度废水可能会对现有水体造成严重损害。在过去的几十年中，已经开发了各种高速率厌氧生物反应器来处理高强度废水。高速率厌氧生物反应器可有效处理工业废水，并以甲烷的形式提供能量。然而,高强度工业废水的物理或化学性质，有时,破坏高速厌氧生物反应器的功能.例如,上流式厌氧污泥床反应器中颗粒污泥的崩解或厌氧膜生物反应器中的膜阻塞是高强度废水处理的结果，这阻碍了正常运行，并可能在经济上损害废水处理厂。生物炭,如果添加到这些生物反应器中，可能有助于缓解高速率厌氧生物反应器的功能不良。这些生物反应器中生物炭工作的主要机制是直接的种间电子转移，微生物固定化，或微生物结构中的基因水平变化。本文对生物炭在高速率厌氧生物反应器处理高浓度工业废水中的应用进行了探讨和综述。
