| 摘 要： | 城市污泥的堆肥过程中,快速、准确的含水率测定方法有助于掌握堆体腐熟程度和水分脱除进程,并据此进行工艺的优化和反馈调控.本文介绍了污泥堆肥的含水率监测方法及其优缺点.由于堆肥物料性质与堆肥环境的特殊性和复杂性,缺乏可直接应用的测定仪器,应根据物料性质、工况条件等选择合适的含水率测定技术,并对相关仪器进行改进.对于污泥堆肥的工程化应用而言,实时在线监测的原位含水率测定方法更适合指导工艺的调控和优化、提高堆肥效率.

| Abstract: | Rapid and accurate moisture measurements are crucial and beneficial to the management of composting process and the optimization of technology. This review summarizes and examines the moisture measurements of compost material during the process of sewage sludge composting. Moisture measurements that could be utilized in composting are introduced and compared. It suggests that instruments for moisture measurements should be modified because of the intricate composting condition. As far as engineering application is concerned, an in-situ moisture measurement based on dielectric method is recommended to guide the composting management and to optimize the technology to improve the composting efficiency. |
