摘要
以硝酸锌、硝酸铝、尿素为主要原料 ,采用均相沉淀法对Al2 O3微滤膜进行了ZnO·Al2 O3涂覆改性研究。实验结果表明 ,在适宜的涂覆液浓度、涂覆次数条件下 ,ZnO·Al2 O3改性后可使微滤膜的水通量提高 1 5～ 2 0 % 。
In this thesis,modified film with Zn-Al Spine is made on the Al 2O 3 microfiltration membrane by homogeneous precipitation method,using Zinc Nitrate,Aluminum Nitrate and urea as raw material.The experimental results showed that:after Al 2O 3 microfiltation membrane is modified by Zn-Al Spine on the condition of suitable concentration and dipping time,its water flux is improved 15～20% and its acid,alkali-resistance also is high.
