固体废物堆肥化及堆肥添加剂研究进展

本文在综合阅读了国内外几十篇文献的基础上，对堆肥化的原理及影响因素做了介绍，在堆肥的影响因素中重点讨论了添加剂的发展概况，对近年来堆肥添加剂的种类和作用做了初步的总结。结果表明了近年来堆肥添加剂已经有了较大的发展，根据其作用可分为微生物接种剂、营养调节剂、膨胀剂(疏松剂)、特定目的调节剂等。其作用可以优化堆肥过程的环境条件，提高微生物活性；加快堆肥化进程，促进堆肥的腐熟；减少氮素损失，保持养分含量；调节堆肥中各种营养元素的含量，提高堆肥质量。

Advance on Composting of Solid Waste and Utilization of Additives

The principle and effecting factors for composting were introduced aft er a comprehension evaluation based on tens articles from both home and abroad.The study c entered on development of compost ad ditives among all effecting factors and summarized category and effect of compost additives.The results showed that:the development of compost additives is great in recent years.Compost additives can be divided int o four groups:i.e microbe inocula,n utrient adjust,bulking agents and a djust for special aims according to the action of compost ad ditives.The additives have the action on composting as following:optim izing the situation of composting process,improving the microbe activity,accelerating comp osting process,reducing nitrogen l osses,retaining nutrient content,adjusting all kinds of nutr ient elements in compost,improving the quality of compost.
