沉淀木质素应用于复合肥生产的初步探讨

Preliminary Study of Producing Compound Fertilizer with Precipitate of Lignin

沉淀木质素是纤维板废液经好氧生化处理的浓缩干燥物,其有机质和腐殖酸含量较高,并含有一定量的氮、磷、钾养分,在土壤中可缓慢降解,可作为原料应用于复合肥的生产,对提高肥料利用率、保护生态环境、减少环境污染具有重要意义。介绍了沉淀木质素的营养成分及其在复合肥生产中的应用,为沉淀木质素在肥料工业上的开发利用提供借鉴。

The precipitation of lignin is concentrated and dried fibreboard wastewater treated with aerobic biochemical process, it is rich in organic matter and humic acid content, it also contains a certain amount of nitrogen, phosphorus and potassium nutrients, it can slowly degrade in soil, and can be used as raw material in production of compound fertilizer, and has significance to improving utilization rate of fertilizer, protecting ecological environment, and reducing environmental pollution. The nutrient of precipitate of lignin and its use in production of compound fertilizer is introduced, providing reference for the development and use of precipitate of lignin in fertilizer industry.
