Production of excessive sludge keeps surging in domestic wastewater treatment plants due to increasing human activities. The disposal costs for the sludge ranges from 30-50% of the total operating and maintenance costs in the wastewater treatment plants, and in most cases, the sludge is finally landfilled after dewatering processes. To reduce the disposal costs and improve sustainability of sludge treatment, development of innovative technologies is essential. A Lystek company that owns "Lystek technique" for sludge pre-treatment look at new biotechnologies capable of capturing energy from sludge, such as methane and hydrogen gas, before being landfilled. Such innovative technologies enable us to reduce disposal expenses substantially and improve treatment sustainability through energy recovery. The goal of the proposed research is to assess a new three-stage anaerobic biotechnology integrating dark fermentation, anaerobic membrane bioreactor and microbial electrolysis cell for the recovery of methane and hydrogen gases from sludge. The success of this research will open up a new, sustainable method to sludge treatment and disposal. We can decrease sludge disposal costs significantly in one hand. In the other hand, a renewable energy market from waste biomass (sludge) will be expanded.

由于人类活动的增加，国内污水处理厂的剩余污泥产量不断增加。污泥的处置成本占污水处理厂总运营和维护成本的30-50%，在大多数情况下，污泥在脱水过程后最终被填埋。为了降低处置成本并提高污泥处理的可持续性，开发创新技术至关重要。一家拥有污泥预处理“Lystek技术”的Lystek公司正在研究能够在填埋前从污泥中捕获甲烷和氢气等能量的新生物技术。这些创新技术使我们能够大幅降低处置费用，并通过能源回收提高处理的可持续性。本研究的目的是评估一种新的三级厌氧生物技术，该技术集成了暗发酵、厌氧膜生物反应器和微生物电解池，用于从污泥中回收甲烷和氢气。该研究的成功将为污泥的处理和处置开辟一条新的、可持续的途径。我们一方面可以显著降低污泥处置成本。另一方面，来自废弃生物质（污泥）的可再生能源市场将扩大。
