- 摘要:
- 在今朝的情况压力下，轮回经济获得快速成长，而强调纳入生态轮回的蓝色成长则突显人类回归天然的属性。保守污水处置固然是人类分泌物的“清道夫”，但本身高能耗、高物耗且不收受接管此中的价值资本，使其处在一种“不能不前行，而又很难可延续”的为难地步。在蓝色成长指引下，污水处置完全能够藉理念与手艺改变为蓝色水工场。蓝色水工场强调养分物、生物材料、热/电和水回用等轮回，首要针对潜伏情况压力触及的两年夜问题——温室气体（需碳中和）和磷危机（要磷收受接管）。蓝色水工场以被誉为下一代污水处置手艺的好氧颗粒污泥为焦点工艺，干化燃烧被用作残剩污泥处置/措置体例，强调收受接管各类价值资本/能源，如前端纤维素、颗粒污泥高值类藻酸盐（ALE）、污泥燃烧电/热、燃烧灰分磷与金属等，特殊正视出水余温热能操纵。蓝色水工场在怪异聪明节制模式下终究对情况能够实现“净零（Net-zero）”影响，同时取得可不雅的经济效益。为此，胪陈了蓝色水工场之框架和相干手艺。
- Abstract:
- Increased environmental pressures have forced us to develop the circular economy. The blue development focusing on ecological cycles highlights the attribute of human beings going back to nature. Wastewater treatment is a kind of “scavenger” for our feces. However, high consumption of energy and chemical usage and little in valuable resources recovery makes it be in an embarrassing situation: “having to go ahead but being unsustainable”. Based on the blue development principles, appropriate ideas and technologies are required for the transformation of conventional activated sludge treatment process into“blue water factories (BWFs)”. BWFs emphasize four sustainable cycles as nutrients, biomaterials, heat/power and water, focusing on alleviating two potential environmental stresses: greenhouse gases (carbon neutrality needed) and phosphorus crisis (phosphorus recovery required). BWFs take the next generation of wastewater treatment: aerobic granular sludge (AGS) as a key technology, and sludge drying and incineration are applied as the ultimate disposal for excess sludge. Valuable resource and energy is mainly recovered, such as celluloses from influent, highly valuable alginate-like extracellular (ALE) from AGS, heat and power from sludge incineration, phosphate & metals from incineration ash, and especially potential thermal energy from effluent. BWFs can not only realize the “Net-zero” impact on the total environment but also obtain a considerable economic benefit under the control of special smart system. The article introduced the framework and the key technologies associated with BWFs.
