A review of moisture measurements in the process of sewage sludge composting
污泥堆肥含水率监测方法的选择与探讨

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.
