Embodiment 1
[0019] The invention provides a technical solution: a sodium lactate decolorization membrane separation process, specifically comprising the following steps:
[0020] S1, pretreating the sodium lactate raw material to obtain a certain concentration of sodium lactate solution;
[0021] S2, the sodium lactate solution is subjected to decolorization membrane fine filtration treatment;
[0022] S3. Packaging the refined filtrate obtained in step S2.
[0023] The pretreatment in step S1 specifically includes the following steps: pour the sodium lactate raw material into a circulation tank, stir with a stirrer, and add an appropriate amount of water to adjust the concentration of the sodium lactate solution to 20%.
[0024] The chromaticity of the sodium lactate solution obtained after the pretreatment in the step S1 is 200APHA.
[0025] The stirring time of the stirrer is 30min, and the stirring speed is 100r / min.
[0026] The decolorization membrane fine filtration treatment in...
Embodiment 2
[0031] The difference from Example 1 is that the concentration of the sodium lactate solution obtained after the pretreatment in step S1 is 30%;
[0032] The stirring time of the stirrer is 40min, and the stirring rate is 80r / min;
[0033] The molecular weight of the decolorizing film is 500Dal;
[0034] The decolorization membrane fine filtration treatment temperature in the step S2 is 30° C., and the pressure is 20 bar.
Embodiment 3
[0036] The difference with Embodiment 1 is:
[0037] The concentration of the sodium lactate solution obtained after pretreatment in the step S1 is 40%;
[0038] The stirring time of the stirrer is 50min, and the stirring speed is 60r / min;
[0039] The molecular weight of the decolorizing film is 150Dal;
[0040] The decolorization membrane fine filtration treatment temperature in the step S2 is 50° C., and the pressure is 30 bar.
[0041] The chromaticity result of the fine filtrate of sodium lactate after the treatment of embodiment one-three is shown in the table below:
[0042] Embodiment one Embodiment two Embodiment Three Chroma / APHA 10 14 20
[0043] It can be seen that after the sodium lactate solution with a chromaticity of 200APHA is finely filtered by the decolorizing membrane system, the chromaticity of the fine filtrate is generally maintained in the range of 10-20APHA, and a good decolorizing effect is achieved.
