求翻译：阳极电解出的Al3+，与水电解出的OH-结合，形成吸附性很强的Al(OH)3，凝聚并吸附废液中的杂质，且阴极发生的还原反应[4-5]，发生化学反应生成很小的气泡，可以把电解后的絮凝物夹带上浮到电解槽的液面，实现油水分离，并降低COD值的目的。实验时需加入NaCl（加入量为1%）提高废乳化液的电导率。是什么意思？

Anode of al3 +, oh-combination of water electrolysis, the formation of the adsorption of highly al.

The anode electrolysis leaves Al3+, the OH- union which solves with the water and electricity, forms adsorbability very strong Al(OH)3, condenses and adsorbs in the waste liquid the impurity, also the negative pole occurs electronation reaction (4-5), has the chemical reaction production very small

Anode electrolytic out of Al3+, and hydropower solutions out of OH-combination, formed adsorption sexual is strong of Al (OH) 3, condensed and adsorption waste in the of impurities, and cathode occurs of restore reaction [4-5], occurs chemical reaction generated is small of bubble, can to electrolyt
