摘要

本研究的重点是了解发展中国家城市废水（MWW）的成分，并评估利用废水能源的技术方案。有关水处理技术和废水能源价值的研究不胜枚举。然而，哪些观点能真正使技术应用变得可行仍有待观察。本研究探讨并介绍了一些可行的创新型中型水处理厂（WWTP）系统的潜力，作为向资源回收、能源中性和污水处理厂生产可再生能源的范式转变。与运营策略、工厂重新设计和现有污水处理厂升级改造有关的各种成本效益机会都得到了直观的体现，这些机会可以促进自力更生的社区。热处理和化学预处理、序批式反应器、厌氧膜流化生物反应器、基于氨的曝气控制以及热电联产系统可以共同促进污水处理厂的能源回收，回收率在 85% 到 111% 之间。研究表明，通过减少疾病、污染和不良的生产机制，将系统升级为自给自足的能源水处理系统，可以抵消与健康和生态破坏相关的多模式成本。

Municipal wastewater for energy generation: a favourable approach for developing nations

This study focuses on understanding municipal wastewater (MWW) constituents and assessing technological options to harness the energy content of wastewater in developing countries. There are numerous research studies related to water treatment technologies and wastewater energy value. However, it remains to be seen which perspectives actually make technology adoption feasible. This study explores and presents the potential for some viable and innovative MWW treatment plant (WWTP) systems as a paradigm shift towards resource recovery, energy neutrality and the production of renewable energy by WWTPs. Various cost-effective opportunities related to operational strategies, plant redesign and the upgrading of current WWTPs that can foster self-reliant communities were visualised. Thermal and chemical pretreatments, sequential batch reactors, anaerobic membrane fluidised bioreactors, ammonia-based aeration control and combined heat and power systems can collectively contribute to energy recovery by WWTPs, ranging from 85 to 111%. The study suggests that upgrading the system to become an energy self-reliant water treatment system outweighs the multimode costs associated with health and ecological damages by reducing diseases, pollution and poor productivity regimes.
