Over the years, wastewater treatment objectives have become more stringent. These objectives demand more energy and higher wastewater treatment operating costs. These increasing costs coupled with emerging sustainability requirements are propelling researchers, industry, and utilities to come up with more efficient ways of managing wastewater. Mainstream wastewater treatment has undergone a paradigm shift; parties now emphasize wastewater energy recovery and the concurrent reduction of energy consumption. This shift enables wastewater treatment plants to achieve energy neutrality while meeting treatment objectives. Despite extensive effort and rapid technological advances, demonstrating mainstream energy neutrality is still challenging due to the diluted nature and lower operating temperature characterizing mainstream wastewater. Other challenges include process complexity, knowledge gaps in process control and the lack of robust technologies.

多年来，废水处理目标变得更加严格。这些目标需要更多的能源和更高的废水处理运营成本。这些不断增加的成本加上不断出现的可持续性要求正在推动研究人员、工业界和公用事业公司想出更有效的废水管理方法。主流废水处理已经发生范式转变；各方现在强调废水能源回收和同时减少能源消耗。这一转变使废水处理厂能够在满足处理目标的同时实现能源中和。尽管付出了广泛的努力和快速的技术进步，但由于主流废水的稀释性质和较低的运行温度，证明主流能源中和仍然具有挑战性。其他挑战包括流程复杂性、流程控制方面的知识差距以及缺乏可靠的技术。
