In the complex system of MeSO4, the removal of Ca2+ and Mg2+ by fluorination precipitation and double salt precipitation deep purification process was studied by single factor method.
分别以浸出液和氟化沉淀液为原料,采用单因素法对复杂MeSO4体系氟化沉淀除钙镁和复盐沉淀深度净化进行了研究。
Conditions of double salt precipitation are that the pH is 1.
以软锰矿、硫化锌精矿及铁屑等为原料,研究了直接法制备锰锌软磁铁氧体的工艺条件,重点研究了浸出液复盐沉淀深度净化的工艺条件。
The procedure includes iron-salt deposition, electrolysis, hydrolytic acidification and aerobic biochemical treatment.
实验结果表明;废水经铁盐沉淀、电解及水解酸化工序后,废水的可生化性显著提高,经好氧生化处理后的水质指标符合国家有关排放标准。
