摘　　要：本文对我国秸秆资源利用和肥料使用现状、清洁制浆技术的进展进行了较为详细的论述,介绍了纸浆与肥料联产的循环经济利用模式的内容和发展前景。该模式采用熔态水解法自制氢氧化钾并联产磷肥以降低原料成本,用氢氧化钾对秸秆进行蒸煮得到纸浆,通过用含钾黑液来制备液体肥料、固体有机肥料和灌溉水,使黑液全部得到资源化利用而实现系统内无污染物排放。秸秆资源来源于农业,所加工的肥料又服务于种植业,同时又生产了造纸工业急需的纸浆,因而采用这种肥料与纸浆联产的技术体系是实现秸秆资源清洁、高效和经济利用的有效途径。Co-production of pulp and organic fertilizer is an effective method to realize clean utilization of stalk. In this paper, the evolution of stalk utilization and clean pulp technique are reviewed in detail. The content of this cycle economic mode and the prospect in future are introduced. The mode applies the melt hydrolyzation technology to prepare KOH and phosphorus fertilizer in order to reduce the material cost, and uses KOH to cook the straw to produce pulp. The black liquor rich with potassium can he used to produce the liquid fertilizer, solid organic fertilizer and irrigation water, and the liquor can he entirely used to achieve resource utilization, therefore no wastes would he released out of the whole system. The straw comes from the crops, and the fertilizer made from the straw return to serve the farming. At the same time the pulp for paper industry is prepared. So the technique system of clean production by the co-production of pulp and fertilizer is the way to realize the clean and effective utilization of straw resource.
