Abstract：

This paper introduces the application of temperature-tolerance ultrafiltration membrane in coal coking waste water treatment. In combination with polyvinylidene fluoride (PVDF) fiber with good performance produced via Thermally induced phase separation (TIPS) and a temperature-resistant epoxy resin, a temperature-tolerance PVDF ultrafiltration membrane module was fabricated, which was used in coking wastewater advanced treatment recycle project. The results showed the stable operation and a significantly improvement of the cleaning effect that in the high-temperature (50 ℃) environment compared with that in conventional cleaning environment (30-35 ℃). Moreover, the cleaning period of vibrating membrane was extended due to the significantly improvement of the feed quality. This paper provides a new way for advanced treatment and reuse of coal coking wastewater.
