农业有机废弃物资源化利用
The resource utilization of agricultural organic waste:taking pruning fruit tree branches to produce liquid organic fertilizer as an example
摘要
Abstract
This study focuses on the low utilization of resource utilization of waste orchard branches,the branches were treated by hot water hydrolysis,to explore the feasibility of fertilizer utilization of branches.Three different temperatures were set at 40℃,60℃and 80℃,and there were three different treatment times of 4 h,8 h and 12 h at each temperature,for a total of 9 treatments.The nutrient and extraction rate of the prepared liquid and residue were analyzed.The results showed that,at the same temperature,the content of nitrogen,phosphorus,and potassium in the extraction solution increases with the increase of treatment time.Under low temperature conditions,the organic carbon content increased with the increase of extraction time,but the long-term extraction at high temperature was not conducive to the increase of organic carbon in the extraction solution.Comprehensive nutrient concentration,organic carbon content,extraction rate,residual rate and loss rate of nitrogen,phosphorus and potassium,60℃-12 h was the best treatment condition.Under this condition,the extraction rates of nitrogen,phosphorus and potassium were relatively high,reaching 17.8%,11.7%and 45.3%,respectively,and the loss rates were low,reaching 5.5%,13.5%and 3.7%,respectively.The preliminary production of waste orchard branches into liquid organic fertilizer by 60℃-12 h thermal hydrolysis is a feasible measure to realize the resource utilization of waste orchard branches in Xinjiang region.关键词
