逝去恋

木虫 (小有名气)

[求助] 求助求助啊。。。 已有1人参与

Recovery of acid effluents for the zinc industry has been chosen for this industrial case study because of the waste volumes produced,the preponderant place this industry holds in the industrial countries and because the available literature on the subject permits a comparison of the efficiency of different recycling techniques. These effluents are generally rich in residual acid and contain, in addition, solubilized metals unreduced during the electrolysis stage.

大神大神,求帮助啊,只用翻译because the available literature on the subject permits a comparison of the efficiency of different recycling techniques这句
