摘要:
针对村镇供水存在水质波动大、传统工艺依赖药剂、膜工艺清洗频繁的难题，研发了一种基于新型聚偏氟乙烯（PVDF）超亲水膜的重力驱动免清洗净水设备。该设备采用“多级预处理+重力流超滤”短流程，摒弃了絮凝剂与化学清洗药剂。在为期6个月、规模为100 m3/d的山涧水源中试过程中，原水浊度在2~1 500 NTU之间波动，设备表现出优异的抗冲击性与稳定性，出水浊度稳定在0.3 NTU以下，微生物指标完全达标。核心膜系统仅依靠每日自动气洗，跨膜压差稳定低于5.0 kPa，实现了长期“免化学清洗”运行。系统电耗仅为0.035 kW·h/m3，产水率达98.5%。该设备通过超亲水膜材料与“重力驱动+气洗维护”模式的创新结合，为偏远地区提供了低碳、高效、运维简便的饮用水处理解决方案。
Abstract:
To address the challenges in rural water supply, including significant fluctuations in raw water quality, dependence on chemical agents in conventional treatment processes, and the high energy consumption associated with frequent cleaning in membrane technologies, this study developed a gravity-driven, chemical cleaning-free water purification device based on a novel PVDF super- hydrophilic membrane. The device employs a short process integrating “multi-stage pretreatment and gravity-flow ultrafiltration”, eliminating the need for coagulants and chemical cleaning agents. During a six-month pilot test with a capacity of 100 m3/d using a mountain stream source, the influent turbidity fluctuated between 2 NTU and 1 500 NTU. The device demonstrated excellent resistance to shock loads and operational stability: the effluent turbidity remained consistently ≤0.3 NTU, and all microbial indicators met the required standards. The core membrane system, relying solely on daily automatic air scrubbing for maintenance, maintained a stable transmembrane pressure below 5.0 kPa, achieving long- term “chemical cleaning-free” operation. The system’s specific energy consumption was only 0.035 kW·h/m3, with a water recovery rate of 98.5%. Through the innovative integration of super-hydrophilic membrane materials with the “gravity-driven and air-scouring maintenance” mode, this research provides a low-carbon, efficient, and easily maintainable drinking water treatment solution for remote areas.
