【摘要】 采用无机陶瓷纳滤膜对淋浴污水进行分离特性试验,重点探讨了膜通量随时间的衰减情况以及操作压差、污水温度和pH值等操作参数对淋浴污水处理效果和膜通量的影响;并就陶瓷膜的污染对膜的清洗方法进行了初步研究。研究结果表明,陶瓷纳滤膜对淋浴污水中COD、TOC和浊度均有一定的去除效果,用水洗+碱洗+酸洗的综合清洗方法可以获得较好的清洗效果更多还原

【Abstract】 A test for separation characteristics of bathing wastewater by ceramic nanofiltration was carried out;the effects of operating time,and parameters such as pressure,temperature and pH value on the quality of the permeate and the flux of the membrane were discussed.The method of membrane cleaning was also preliminarily studied.The results showed that the ceramic nanofiltration membrane could remove COD,TOC,and turbidity of the bathing wastewater effectively,and washing the membarane with water,NaOH and HNO3 as cleaning agent could achieve better effect in this test.更多还原
