Estimation Total Algae Biomass of Xinyun Lake and Analysis of the Benefits for Utilization of Organic Fertilizer from Algae

Abstract

Combined with the sample monitoring of our research and the previous studies of algae growth kinetics,the total algae biomass of Xinyun Lake that can been gathered and removed was fast estimated as 1218800m3/a. Based on the research work about the result of organic fertilizer from algae paste, the internal pollution load reductions of COD, NH4-N and available phosphorus were estimated as 13163.04t, 1018.91t and 146.26t, respectively, in 2012. At last, the environmental benefit, economic benefit and social benefit of organic fertilizer from algae were analyzed, and all of them were very significant.
