The filtrate (liquid of the first plate and frame filter press is connected with circulatory pool；Also include albumen precipitation pond and the second plate and frame filter press, ceramics
The dope outlet of film device and nano-filtration membrane equipment is connected with albumen precipitation pond, dope outlet and second sheet frame in albumen precipitation pond
Filter press is connected, and the filtrate (liquid of the purified liquor outlet in albumen precipitation pond and the second plate and frame filter press is connected with Waste pond.
Using having the beneficial effect that for the utility model waste water produced in potato starch manufacturing retracting device, ceramic membrane, nanofiltration are taken
The technology that film, reverse osmosis membrane and Aerobic Process for Treatment are combined, the foam in waste water is completely eliminated first with film process equipment, so that
Biochemical Aerobic Process for Treatment is achieved, meanwhile, effectively remove the organic matter in waste water；Make the egg in waste water using albumen precipitation process
White matter and starch are effectively reclaimed；During produce clear liquid can also be further used for clean potato；The mud cake of generation
Also can further recycle；Realize the recycling and zero-emission of technique waste water in farina production process；
In addition, the installation area is small, operating cost is low, and operation and maintenance process are simple and convenient, and non-secondary pollution, comply fully with
The idea of development of today's society energy-conserving and environment-protective.
