摘要:- 在目前的環(huán)境壓力下，循環(huán)經(jīng)濟得到快速發(fā)展，而強調(diào)納入生態(tài)循環(huán)的藍色發(fā)展則突顯人類回歸自然的屬性。傳統(tǒng)污水處理雖然是人類排泄物的“清道夫”，但自身高能耗、高物耗且不回收其中的價值資源，使其處于一種“不得不前行，而又很難可持續(xù)”的尷尬境地。在藍色發(fā)展指引下，污水處理完全可以藉理念與技術(shù)轉(zhuǎn)變?yōu)樗{色水工廠。藍色水工廠強調(diào)營養(yǎng)物、生物材料、熱/電和水回用等循環(huán)，主要針對潛在環(huán)境壓力涉及的兩大問題——溫室氣體（需碳中和）和磷危機（要磷回收）。藍色水工廠以被譽為下一代污水處理技術(shù)的好氧顆粒污泥為核心工藝，干化焚燒被用作剩余污泥處理/處置方式，強調(diào)回收各種價值資源/能源，如前端纖維素、顆粒污泥高值類藻酸鹽（ALE）、污泥焚燒電/熱、焚燒灰分磷與金屬等，特別重視出水余溫熱能利用。藍色水工廠在獨特智慧控制模式下最終對環(huán)境可以實現(xiàn)“凈零（Net-zero）”影響，同時獲得可觀的經(jīng)濟效益。為此，詳述了藍色水工廠之框架及相關(guān)技術(shù)。
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.
