反渗透膜截留二级出水中重金属离子试验研究

The experimental studies for reverse osmosis process rejects heavy metal irons in secondary effluent

为了考察反渗透膜对污水中重金属离子的去除效果,采用MCM-RO(微滤—活性炭—微滤—反渗透)工艺对邯郸市东郊污水厂氧化沟工艺二沉池出水进行了深度处理,实验结果表明,该工艺对砷、镉、铅三种重金属的去除效果非常明显,出水水质稳定。

With the aim of reviewing the effect of reverse osmosis remove heavy metal irons in wastewater. The Microfitration-actived Carbon- Mierofitration-Reverse Osmosis membrane process was used to treat effluent water from secondary settling tanks of oxidation ditch process of Handan east wastewater treatment plant. It is analysised that the effection of process remove heavy metal irons is obvious, and the final effluent is stable.
