Innovative technologies & processes enabling energy neutral wastewater treatment

多年来，废水处理目标变得越来越严格。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新兴的可持续性要求，促使研究人员、工业和公用事业部门提出更有效的废水管理方法。主流废水处理经历了范式转变；各缔约方现在强调废水能源回收和同时减少能源消耗。这种转变使污水处理厂在满足处理目标的同时实现能源中和。尽管付出了巨大的努力，技术也取得了快速的进步，但由于主流废水的稀释性质和较低的工作温度，证明主流能源中性仍然具有挑战性。其他挑战包括过程复杂性、过程控制方面的知识差距以及缺乏可靠的技术。

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.
