- 摘要:
- 针对市政污泥，对污泥高压无热深度脱水干化技术的设备性能和工程应用效果进行了分析，得到了最佳运行参数。结果表明，在高压压榨装置液压系统运行压力为14 MPa、污泥摊铺总厚度为2 cm、装置压榨时间为4 h的条件下，可将污泥含水率从80%左右降低至45%左右；将微风干化仓污泥摊铺厚度控制在3 cm时，1 h后含水率可降至40%。以安徽省六安市某污水厂为例，污泥处理规模为30 t/d的工程应用结果表明，相比传统热干化脱水技术，污泥高压无热深度脱水干化技术运行成本降低40%以上，且全过程无热处理，达到了节能减排目的，响应了国家“双碳”战略。
- Abstract:
- The equipment performance and engineering application effects of the high-pressure non-thermal deep dewatering and drying technology for municipal sludge were analyzed, and the optimal operating parameters were obtained. The results showed that when the hydraulic system operating pressure of the high-pressure pressing device was controlled at 14 MPa, the total sludge spreading thickness was 2 cm, and the pressing time was 4 hours, the sludge moisture content could be reduced from about 80% to about 45%. When the sludge spreading thickness in the breeze drying silo was controlled at 3 cm, the moisture content could be reduced to 40% after 1 hour. Taking a sewage treatment plant in Lu’an City, Anhui Province as an example, the engineering application results treating 30 t/d of sludge showed that compared with traditional thermal drying and dewatering technology, the operating cost of this high-pressure non-thermal deep dewatering and drying technology was reduced by more than 40%. Moreover, there was non-thermal treatment throughout the entire process, achieving the goal of energy conservation and emission reduction, and responding to the national “dual carbon” strategy.
