Potential utilization of anaerobic fermentation sludge of Enteromorpha prolifera
摘要
Abstract
Anaerobic fermentation sludge of biomass is rich in nutrition and active materials, and it is a resource of high development value. This study investigates the pretreatment, pelletizing and drying methods of sludge which comes from the anaerobic fermentation of Enteromorpha prolifera, and analyzes the nutritional components of the sludge. The formed sludge pellets from anaerobic fermentation of Enteromorpha prolifera goes through 70 min hot air drying at 60^ , becomes the final products with moisture content of blow 13% , and the organic matter, total phosphorus and total potassium in the sludge pellets reach to 55. 68% , 2. 72% and 0.048% , respectively. In addition, the sludge pellets keep a good shape and high surface quality. The sludge from anaerobic fermentation of Enteromorpha prolifera is accordingly high-quality raw material for organic fertilizer production.关键词
