摘要
本文介绍了河北某生物科技公司利用造纸污泥做有机肥的生产经验。生产实践显示,采用好氧堆肥(生物干化)技术,解决了造纸污泥难以低成本快速脱水问题;造纸污泥与秸秆粉和鸡粪合理搭配可以制成精制有机肥,田间试验结果表明,使用该有机肥可以减少化肥用量;造纸污泥堆肥的长期施用对土壤重金属的累积量和作物中累积行为还需要进一步研究。
Paper mill sludge is a kind of valuable biomass resource, its utilization not only can solve the problems of the secondary environmental pollution, but also obtain a certain economic benefit. Production of organic fertilizer with sludge is conducive to ecological environment, and to make a significant contribution to the development of ecological agriculture. The practical experience in the production of organic fertilizer with paper mill sludge was introduced in this paper.
