This proposal addresses a study of the integration of waste activated sludge (WAS) pretreatment technologies with anaerobic membrane bioreactors (AnMBR) for enhanced sludge digestion. AnMBRs decouple the hydraulic residence time from the solids residence time and have been found to achieve substantial solids destruction at high organic loading rates while producing a thickened product. It is hypothesized that pretreatment of the sludges would allow for even greater AnMBR throughput. The process would be more stable than the use of continuous flow stirred tank reactors for digestion and would achieve pathogen reduction that is similar to conventional anaerobic digestion due to

本研究旨在探讨将活性污泥预处理技术与厌氧膜生物反应器（AnMBR）相结合以强化污泥消化的可行性。AnMBR将水力停留时间与固体停留时间分离，并且已经发现在高有机负载率下实现实质性的固体破坏，同时产生增稠的产物。据推测，污泥的预处理将允许更大的AnMBR吞吐量。该方法将比使用连续流搅拌槽反应器进行消化更稳定，并且将实现与常规厌氧消化类似的病原体减少，这是由于
