- 摘要:
- 全自动滤布行走式压滤机具有污泥脱水效果佳、工作周期短、快速自动卸泥、快速自动清洗、节省能耗、无需人工操作等特点。某污水处理厂采用全自动滤布行走式压滤机对经过浓缩且含水率降至97%以下的剩余污泥进行处理。通过添加不同比例的聚合氯化铝（PAC）调理剂，分析其每个周期的处理量和脱水泥饼的含水率，结果显示，PAC加药比［药剂有效成分与绝干污泥（DS）质量之比］为2.0%、2.5%时，处理效果最佳，设备处理能力分别达到2.39、2.51 kgDS/（m2·h），泥饼含水率普遍低于55%。
- Abstract:
- Automatic moving-cloth filter press demonstrates outstanding sludge dewatering performance, short working cycles, rapid automatic sludge discharge, efficient automatic cleaning, energy- saving operation, and unmanned operation characteristics. In a practical application at a municipal wastewater treatment plant, the equipment processed concentrated residual sludge with moisture content below 97%. By adding conditioning agents at different ratios, the study investigated both the treatment capacity per cycle and the moisture content of dewatered sludge cakes. Research results indicate that when using polyaluminum chloride(PAC) as the sludge conditioner with the weight ratio of active agent components to dry sludge(DS) weight is 2.0% and 2.5%, the automatic moving-cloth filter press achieves optimal performance. Under these conditions, the treatment capacity reaches 2.39 kgDS/(m2·h),2.51 kgDS/(m2·h) respectively, while consistently maintaining the moisture content of sludge cakes below 55%.
