| Zusammenfassung: | The invention relates to a biochemical treatment method for industrial waste water of methionine. The method comprises the following steps that 1, an extraction agent is used for extracting the waste water, and an organic phase and a water phase are obtained after separation is carried out; 2, stream stripping is carried out on the water phase to separate out a part of organic matter; 3, a mashing method is used for removing formaldehyde of the water phase; 4, biochemical treatment is carried out on the water phase by means of cooling. As the method is utilized for treating the industrial waste water of methionine, energy consumption is remarkably reduced compared with that of the prior art, and the substance utilization rate is increased. |
