采用扩散渗析法处理树脂酸洗液，进行硫酸回收和杂质分离的实验研究。整个实验考察了扩散渗析装置料液流量、水流量与料液流量比及料液酸度对硫酸回收率的影响，并用公式进行验算。结果表明，采用扩散渗析器具有良好的分离性能，料液流量为10 mL／min ，蒸馏水流量10．5 mL／min ，酸度为51．6～95．4 g／L时，酸回收率均在70％以上，金属离子截留率也基本在90％以上，较好的实现了酸与杂质的分离以及酸的回收。

The diffusion dialysis method is used to treat resin acid lotion and this process is employed to recycling H2 SO4 and impurities from the mineral acid wastewater .The effects of the liquid flow ,flow rate ratio(Qk/Qy )of diffusion dialysis and acidity into consideration on sulfuric acid recovery rate are investigated and the formula is used to calculate .The results show that it is satisfying by using diffusion dialysis ,when under the conditions of the liquid flow 10 mL/min ,the distilled water flow 10 .5 mL/min and acidity 51 .6~95 .4 g/L ,the recovery rate of acid can reach above 70% and the valuable metals recovery rate can also reach more than 90% ,which achieves the results of separation of acid and impurities and acid recycling .
