Abstract：

Through the pilot study on treating Titanium dioxide wastewater by Ultrafiltration+Reverse osmosis technology, reviewed the flux,water production time and drain cycle of Ultrafiltration is 38.8LMH, 22min and 22, turbidity of production water less than 0.2NTU, water recovery is about 92%. Flux of reverse osmosis is 15LMH, water recovery is about 60%～65%, clean cycle is about 22～28day. The parameter optimization of Ultrafiltration+Reverse osmosis is received.
