对餐厨废弃物发酵产黄腐酸分离纯化的工艺条件进行研究，优化离子交换法的工艺参数，以获得高纯度的发酵产黄腐酸。利用单因素试验，采用 H ＋型和 NH4＋型阳离子交换树脂对餐厨废弃物发酵产黄腐酸进行分离纯化，通过比较2种树脂对黄腐酸粗提液静态交换吸附的效果，筛选出用于黄腐酸溶液纯化的较适合的阳离子交换树脂类型；并利用三因素（上样流速、层析高径比、上样浓度）三水平的正交试验，对筛选出的阳离子交换树脂的纯化工艺参数进行了优化。结果表明：采用离子交换法纯化餐厨废弃物发酵产黄腐酸的最佳工艺条件是采用 NH4＋型阳离子交换树脂，柱高径比5∶1，上样流速1 BV /h，上样浓度为Na ＋初始浓度≤700 mg /L （相当于原料0.1 g /mL）。利用该工艺对黄腐酸粗提液进行分离纯化，除杂效果最好， Na ＋去除率为95.90％，黄腐酸含量可达到82.10％。

Biochemical fulvic acid produced from kitchen waste was purificated in this paper, purification parameters were researched to obtain high-purity fulvic acid.Purification of biochemical fulvic acid was researched by H + and NH4 + cation exchange resin, through the comparison of exchange adsorption effect of 2 kinds of resin, screened out the cation exchange resin suitable for purification of biochemical fulvic acid by the single factor experiment, then the purification parameters of the selected cation exchange resin were optimized using the orthogonal test with three factors (injection velocity, aspect ratio, injection concentration) and three levels.The results showed that the optimum process conditions for purification of biochemical fulvic acid produced from kitchen waste by ion exchange were using NH4 + cation exchange resin, 5∶1 of aspect ratio, 1 BV /h of injection velocity, initial concentration of Na + ≤ 700 mg /L ( raw material 0.1 g /mL of injection concentration ) .Under the conditions, Na + desalination rate reached 95.90%, biochemical fulvic acid concentration could reach 82.10%.
