The invention relates to a treatment method of
wastewater containing
dimethylamine. The method comprises the following steps of: introducing
raw water of the
wastewater containing the
dimethylamine into a reactor, adding a salt forming agent, controlling the pH value at 3-4, and performing full reaction; hoisting a solution after reaction by a water pump, enabling the solution to enter a first-stage
reverse osmosis device, separating by a first-stage membrane, then enabling the
produced water to enter a
water production box, and enabling first-stage concentrated water to enter a second-stage
reverse osmosis device; separating by a second-stage membrane, then enabling the
produced water to enter the
water production box, and transferring second-stage concentrated water into an external unit for recovering the
dimethylamine in the concentrated water; and adding alkali liquor into the
water production box, regulating the pH of the water in the water production box to 6.5-7.5, hoisting by the water pump, enabling the water to enter a third-stage
reverse osmosis device, separating by the membrane, then enabling the
produced water to enter a recycling water box for being recycled for production, enabling third-stage concentrated water to return to the reactor of the
raw water of the
wastewater containing the dimethylamine for mixing with the raw mater, and then performing circulating treatment. The treatment method has the characteristics of reducing the emission of the wastewater, reducing the environmental
pollution, improving the repeated
utilization rate of
water resources and the like.
