摘要:
为了降低高浓度化学镀镍废槽液处理成本,采用氧化-沉淀预处理-正渗透(FO)组合工艺对废槽液进行常温浓缩减量. FO膜为水通道蛋白膜(AQP),汲取液为4 mol·L-1 NaCl溶液,FO过程采用活性层朝向原料液(AL-FS)的模式. 当采用H2O2加CaO进行预处理时,废液电导率、TP、TOC和Ni的去除率远高于其他预处理方案. 当CaO添加量为5%时,系统水通量可达到5.89 L·(m2·h)-1; 浓缩后污染物TP、Ni和TOC的截留率分别达到 73.97%、92.90%和84.65%. 三维荧光图谱(EEM)结果显示,有机物类腐殖酸组分比酪氨酸或色氨酸蛋白类物质更容易透过半透膜从原料液进入到汲取液中. 适量的CaO预处理不仅可以有效的降低污染物的浓度和渗透压,有利于后续FO工艺浓缩减量,而且节约了经济成本.
Abstract:
In order to reduce the treatment cost of high concentration electroless nickel plating waste bath,the combined process of oxidation-precipitation pretreatment-forward osmosis(FO)was used to concentrate and reduce the waste bath at room temperature. The aquaporin membrane(AQP)was used as the FO membrane,the draw solution was the 4M NaCl solution,and the FO process adopted the mode that the active layer was facing to feed solution(AL-FS). When H2O2 and CaO were used for pretreatment,the removal rates of electrical conductivity,TP,TOC and Ni of the waste bath are much higher than those of other pretreatment schemes. When 5% of CaO was added,the system water flux could reach 5.89 L·(m2·h)-1; the rejection ratio of pollutants TP,Ni and TOC after concentration were 73.97%,92.90% and 84.65%,respectively. EEM results showed that organic-like humic acid fractions were more likely to pass through the semipermeable membrane from the feed solution to the draw solution than tyrosine or tryptophan protein-like substances. Taking the appropriate amount of CaO for pretreatment can not only effectively reduce the concentration and osmotic pressure of pollutants,which is conducive to the concentration of the subsequent FO process,but also save the economic cost.
