Research on vacuum membrane permeation crystallization treatment of high-salt wastewater
The vacuum membrane infiltration crystallization process was used to treat high-salt wastewater.The effects of operating temperature,feed flow rate,feed temperature,and membrane usage on the desalination rate of high-salt wastewater were compared.The experimental results show that the best desalination effect is achieved for high-salt wastewater at operating temperatures of 75 to 80℃,feed flow rate of 65L·h-1,and feed temperature of 39℃,with a desalination rate of over 97%.And the reuse of the membrane within 10 times has little effect on the desalination rate of high-salt wastewater,providing fundamental theoretical support for its further industrial application in the treatment of high-salt wastewater.
