城市污泥好氧堆肥研究进展

Research Progress of Aerobic Composting of Urban Sludge

好氧堆肥与其他常见污泥处理方式相比具有有机物降解快、彻底、无害化程度高、堆肥产品肥效好等优点。根据国内外污泥好氧堆肥研究现状,从C/N、温度、含水率、pH等方面,介绍了好氧堆肥过程的控制要点,总结了污泥好氧堆肥适宜的技术条件;分析了微生物菌剂在好氧堆肥中的重要作用。最后指出堆肥产品需依靠技术进步和完善相关行业标准来开拓市场。

Compared with other common sludge treatment methods , aerobic composting has the advantages of quick and thorough degradation of organic matter, high degree of harmless, and good fertilizer efficiency from the compost.According to the current status of sludge aerobic composting at home and abroad, the controlling essentials of composting progress, such as C/N, temperature, moisture and pH, were intro-duced in this paper.We summarized the appropriate technical conditions of sludge aerobic composting and stressed the important role of micro-bial agents during composting.Finally, the suggestions were proposed that the final compost needed to rely on technological progress as well as the development and implementation of related industry standards to expand the market.
