摘要
污水直接膜过滤可实现水、肥双成分农业资源化。膜组件运行操作方式对获得稳定的膜通量,延缓、降低膜污染至关重要。通过试验,确定了针对城市污水直接膜过滤应选择的合适错流速度、料液温度以及采用低压恒通量操作的模式。
Wastewater resource and nutrient could be reclaimed by direct filtration of raw wastewater with membrane technology. The membrane operational modes are of great importance to producing a satisfied filtrate flux, and lessening membrane fouling. This article presents an experimental determination for optimal operational parameters, such as cross velocity, trans-membrane pressure, temperature and fixed flux operation, etc.
