Embodiment 1
[0023] A kind of processing method utilizing turmeric waste water to produce water-soluble fertilizer, comprises the following steps:
[0024] S1. Mix the solution to remove impurities, put the papermaking wastewater into the container, slowly add the yellow wastewater into the container according to the weight ratio of 4:1, stir and mix well, and then pass the mixed solution through a 1mm filter to remove the solution Medium and large particles of impurities;
[0025] S2, enzymatic hydrolysis of the solution, add the above mixed solution into the enzymolysis container, add cellulase, neutral protease, and xylanase according to the concentration ratio of 2.5U / mL, 2U / mL, and 1.8U / mL, and control the container The temperature is 60°C, enzymatic hydrolysis for 65 minutes, and the solution is constantly stirred during the enzymatic hydrolysis process. After the enzymatic hydrolysis is completed, let it stand at room temperature for 30 minutes, and pass the supernatant through a 60...
