针对酿造用水水质不达标造成酒厂产品合格率降低这一状况,采用“预处理过滤+反渗透脱盐+臭氧杀菌”工艺对地下水进行处理,产水电导率维持在5μS/cm左右,CODcr和菌落数均为检出,产水水质达到GB 17324-2003《瓶(桶)装饮用纯净水卫生标准》,同时采用2%柠檬酸和10%Na-SDS的清洗方案对恢复膜通量具有显著效果。
In view of the fact that the quality of brewing water is not up to standard, the qualified rate of brewery products is reduced. The groundwater is treated with “pretreatment filtration + reverse osmosis desalination + ozone sterilization ” technology, and the water conductivity of the produced water is maintained at about 5 μS / cm. CODcr And the number of colonies were detected, the water quality reached GB 17324-2003 “bottle (barrel) purified drinking water health standards,” while using 2% citric acid and 10% Na-SDS cleaning solution on the recovery membrane flux has Significant effect.
