添加氮损失抑制剂对蓝藻泥堆肥质量的影响
Effect of adding nitrogen loss inhibitor on quality of dehydrated blue-green algae compost
摘要
Abstract
The dewatered blue-green algae composting were investigated in this study through production composting test. The physical and chemical properties of compost product were studied with addition of nitrogen loss inhibitor-calcium superphosphate in compostiong process. The results showed that the composting materials could reach maturity after 37 days for treatment and control group, and the compost fertilizer met the related organic fertilizer standard ( NY525-2002) . However, the product quality of treatment group with addition of calcium superphosphate was better than the control group, total N, total P, and total K were 490 g/kg, 20.75, 10. 02 and 11.32 g/kg, respectively. In addition, during the composting, algae toxin MC-RR and MC-LR removal efficiencies were 89. 8% and 78. 3% , respectively due to the biodegradation of microorganisms in control group. It is noteworthy that the removal efficiencies of MC-RR and MC-LR presented were further enhanced in treatment group as the corresponding removal rates increased to 92. 3% and 100% , respectively, which ensured the security and feasibility of the application of algae compost in agricultural field.关键词
