摘要
我国污泥产量逐年增长,污泥处置问题面临严峻挑战。污泥堆肥技术因其符合绿色发展理念,是极具发展潜力的污泥处置技术。高效化、高值化、智能化是目前污泥堆肥技术的发展方向。从堆肥调理剂的优化发展、污泥堆肥的曝气策略、除臭工艺及堆肥设备的工艺优化等方面,归纳总结了目前污泥堆肥技术工艺的发展现状及面临的主要问题。提出从废物利用、可回收设备研发利用、生物生命活动利用的角度开发堆肥调理剂;结合传感器反馈、软件数值模拟等技术,改良堆肥工艺设备;引进新型曝气及除臭工艺,研发高效堆肥设备。以期为可为我国污泥堆肥工艺的发展及相关研究工作提供参考。
As sewage sludge production in China is increasing year by year, sewage sludge disposal is facing with severe challenges. Sewage sludge composting technology is a potential SS disposal method that in line with the concept of sustainable development. High efficiency, high value and intelligence are the developing direction for SS disposal. In this paper, the development status and the main challenge of sewage sludge composting was summarized from the aspects of the optimization of composting conditioner, aeration strategy, deodorization process and the composting equipments. The result showed that the composting conditioner ought to be developed, taking waste utilization, recyclable equipment and biological utilization into consideration. The composting equipment needed to be improved with the combination of sensor feedback and software numerical simulation. Moreover, the introduction of new aeration and deodorization process were needed to develop efficient composting equipment. This study provided valuable suggestions for the further promotion and development of sludge composting technology in China.
