Microalgae have been considered as an efficient microorganism for wastewater treatment with simultaneously bioenergy and high value-added compounds ***,the high energy cost associated with complicated biorefinery(*** cultivation,harvesting,drying,extraction,conversion,and purification)is a critical challenge that inhibits its large-scale *** different nutrition(***,nitrogen and phosphorous)sources,food processing wastewater is a relative safe and suitable one for microalgae cultivation due to its high organic content and low *** this review,the characteristic of different food wastewater is summarized and *** potential routes of value-added products(***,pigment,polysaccharide,and amino acid)production along with wastewater purification are *** existing challenges(*** cost,efficiency and mechanism)of microalgal-based wastewater treatment are also *** prospective of microalgae-based food processing wastewater treatment strategies(such as microalgae-bacteria consortium,poly-generation of bioenergy and value-added products)is *** can be observed that food wastewater treatment by microalgae could be a promising strategy to commercially realize waste source reduce,conversion and reutilization.

本文研究了有机固体废弃物厌氧酸化过程中,酸化产物对酸化性能的影响。试验在中温条件下,利用水平旋转反应器进行重复序批式培养,采用面粉作基质,污泥为接种菌,按1:1的比例混合加入到反应器中,醋酸作为模拟酸化产物。试验共分四组,每组由五个反应器组成,反应时间分别是5、10、15、20、25d。第一组作为对照组,第二、三、四组的各反应器分别加入0.25、0.5、0.75mL醋酸。结果显示,pH值范围为5.01—4.71,挥发性有机酸的增长率范围为-11%—408.3%、挥发性固体的降解率范围是27.3%—46.3%、基于表面降解动力学常数范围是1.08—1.4。表明,酸化产物的大量累积会阻碍水解酸化过程。

关键词：厌氧发酵固体废弃物挥发性有机酸基于表面降解动力学常数
