摘要
生活污泥机械脱水后含水率仍高,影响处理和处置效率。电渗透技术能够有效地降低生活污泥含水率,经过前置预处理再经电渗透装置脱水后,污泥含水率低于60%,经12小时的自然晾干,含水率降到低于30%,实现减量化和资源化利用。
The water content was still high after the mechanical dehydration of domestic sludge, which affects the efficiency of treatment and disposal. Electroosmosis technology effectively reduced value. It was less than 60% after pre-treatment and dehydration by electroosmosis device. The water content was reduced to less than 30% after 12 hours of natural drying. The purpose of reduction and resource utilization was realized.
