摘要
介绍了研究污泥经生物淋滤后N,P,K等营养物质流失情况的材料与方法,阐述了测定污泥中N,P,K含量的方法及原理,对生物淋滤前后污泥中N,P,K的变化作了分析,结果表明:污泥经生物淋滤后N,P,K含量分别为1.53%,0.58%,0.28%,仍能保持较好的肥效。
The material and method of studying N, P and K nutrient material running off situation after biologic leaching were introduced. The measuring method and principle of N, P and K in sludge were illustrated. Through analysis of N, P and K change in sludge after and before biologic leaching, the result indicated that the N, P and K content in sludge after biologic leaching was 1.53 %, 0.58 % and 0.28 % respectively, which still had better fertilizer effect.
