摘要
研究了不同进水温度下,超疏水膜装置处理榨菜综合废水的污染物去除性能和膜通量变化情况。结果表明,进水温度对超疏水膜装置处理榨菜综合废水污染物去除效果影响不明显,膜通量和接触角随进水温度的增加而增加。综合考虑污染物去除效果及膜通量,进水温度不低于60℃时超疏水膜装置处理榨菜废水效果较佳。
The change of pollutant removal performance and membrane flux of comprehensive wastewater from mustard tuber treated by superhydrophobic membrane device at different water inlet temperatures are studied.The results show that the inlet watertemperature have no obvious effect on the removal of pollutants from comprehensive wastewater of tuber mustard treated by super hydrophobic membrane device,and the membrane flux and contact angle increase with the increase of inlet water temperature.Considering pollutant removal and membrane flux comprehensively,the super hydrophobic membrane device has better effect on treating mustard tuber wastewater when inlet water temperature is not less than 60℃.
