Our country has very much bean product production enterprise;every day them produces massive productions wastewater.Highly concentrated wastewater(whey waste water)center includes massively has the value ingredient, at the same time these ingredients also is in the waste water main pollutant. Along with membrane separation technology development, use membrane separation technology processing and recycling whey wastewater research quite a lot, but extremely few truly enters the production implementation stage. In order to thoroughly discusses the whey wastewater the again resources use, carried on has used the intensified technology processing whey wastewater the research.The paper studied the Distribution situation of the valuable component to drain in the whey wastewater which in the bean product processing process; the pretreatment craft of The recycling of valuable component and the choice of the separation membrane and the separates craft; After combination membrane processing the distributed situation of function ingredient and main pollutant in each membrane separation unit; we has Initially discussed that used the resin adsorption recycling isoflavone and the Saponin and formulated the processing craft the whey waste water to reach the wastewater drain standard and the best recycling craft active constituent.The research indicated that: The whey waste water has the higher recycling use value; Before the separation recycling must carry on the suitable pretreatment to the whey waste water, removes the impurity and guarantee membrane separation process normal operation. Using the MWO is 30,000 UF membranes, the NF membranes which desalinization rate is 70% and the RO membrane which desalinization rate is 98% combination processing, Ultra filtered has realized the separation of sugar and protein .The separation of Different molecular weight protein, The NF has intercept the major part of soybean oligosaccharides in the whey. The wastewater After RO membrane processing may again use; Uses the D101 resin to adsorption the NF intercept fluid. The isoflavone returns-ratio is 94%, the Saponin returns-ratio is 92%.
