Abstract Wastewater and waste gas containing dimethylamine mainly come from the purification process of dimethyl formamide (DMF) aqueous solution. Some current relevant treatment methods including low-temperature plasma purifier, weak acid cation exchange resin, air stripping, direct wastewater biochemical treatment and membrane filtration etc.were presented. And then the harnessing effect and feasibility of these methods on were proposed. It is pointed out that due to some drawbacks in treating dimethylamine wastewater or waste gas, the cost and secondary pollution should be taken into account in the future.
