Abstract

The invention relates to a semen armeniacae amarae debitterizing water recycling method. The method mainly includes: roughly filtering semen armeniacae amarae debitterizing water, using a ceramic membrane of 5-10nm in pore diameter for concentrating and filtering, separating protein from amygdalin to obtain concentrate A and permeate B, intercepting protein in the concentrate A for recycling, filtering the permeate B through an organic membrane of 150-300Da to obtain concentrate C and permeate D, and intercepting macromolecular substances like amygdalin and benzaldehyde in the concentrate C. Membrane separation technology is adopted to concentrate and separate nutritional substances in the semen armeniacae amarae debitterizing water, concentrated nutritional substances are easier for purifying and extracting, cost for extracting the nutritional substances can be reduced, and substances like high-purity amygdalin, flavone and polyphenol and natural perfume substance benzaldehyde can befurther concentrated and separated out; final wastewater obtained by treatment reaches indexes of national wastewater treatment, and the method plays a certain role in environment protection.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment, and in particular relates to a method for the resource utilization of debittered water from bitter almonds. Background technique [0002] Bitter almond is the bitter seed kernel of the ripe fruit of the Rosaceae plant. It is widely distributed at home and abroad. It is mainly produced in Inner Mongolia, Hebei, Shaanxi, Gansu and other places in China, and the resources are very rich. Bitter almonds are rich in nutrients, containing 25% protein, about 50% crude fat, and about 10% sugar. According to reports, there are a lot of unsaturated fatty acids in almond oil, mainly oleic acid and linoleic acid, accounting for 90% of fatty acids. ;Each 100g of almonds also contains 65.8mgVE, so almond oil has anti-aging, cardiovascular disease prevention and other effects, is a good tonic. [0003] Bitter almond contains about 3% amygdalin, which can be decomposed (hydrolyzed) to produce benza...
