Advances and Key Problems on Anaerobic Digestion of Algae from Algal Bloom

综述了目前水华藻类厌氧消化的研究进展,包括水华藻类的种类和组分、厌氧消化特性、共消化方法、预处理方法、藻毒素的降解情况以及沼液沼渣的资源化途径等,最后提出了水华藻类厌氧消化需要关注的优化脱水、调控碳氮比、水华季节性、预处理破胞、沼液沼渣科学施用等问题。

Algal bloom caused by eutrophication of lakes is an important problem for some of the lakes in our coun-try. Disposing algae refloated from Dianchi Lake by anaerobic digestion is an important end - treatment method to solve the problem of algal bloom. This paper summarized the current research process of anaerobic digestion of al-gae from algal bloom, including the form of algae, the characterization of anaerobic digestion of algae and co - di-gestion between algae and sludge, pre - treatment method of algae, the degradation of microcystins and the ways of recycling the biogas slurry and residue. Then some problems that we need to concemcame out such as the optimiza-tion of dehydration, the control of the C/N, seasonal effects on algal bloom, methods and effects of the pre - treat-ment on algae, the scientifically use of biogas slurry and residue.
