RESEARCH PROGRESS OF TECHNICAL OPTIMIZATION OF SEWAGE SLUDGE COMPOSTING

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.
