摘要:研究了浒苔(Enteromorpha prolifera)厌氧发酵产气剩余污泥的预处理、成形和干燥加工方法,并对剩余污泥的营养成分进行了测定与分析。成形后的浒苔厌氧发酵产气剩余污泥颗粒,经过60℃热风干燥70 min,终产品含水量可降至13%以下,而且污泥颗粒中的有机质、全钾(K)和全磷(P)含量分别达到55.68%、2.72%和0.048%。污泥颗粒保形好,表面质量高,浒苔厌氧发酵产气剩余污泥是机肥料生成的优质原料。

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 below 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.

Key words: Enteromorpha prolifera; anaerobic fermentation; sludge; pelletizing; drying; organic fertilize
