Summary:Heavy metals are common pollutants in contamination-involved emergencies. During recent years, heavy-metal-contaminated emergencies tend to occur more frequently with high intensity. The sulphide precipitation integrated membrane reactor is used to treat heavy-metal-contaminated water with Na2S acting as precipitant for heavy metals. Through pilot test, the qualities of effluent satisfy the class III water quality of “quality standard for ground water” (GB14848-93). Thus the sulphide precipitation integrated membrane reactor is proved as an effective method for removing the heavy metal in groundwater with high efficiency.
