摘　　要：与传统浸水工艺对比研究了酶浸水獭兔皮的组织切片,蛋白溶出率、成品皮物理力学性能以及废液BOD、COD和TOC。结果显示:酶浸水獭兔皮胶原纤维分散情况良好,毛囊未受损害,蛋白溶出率高,成品皮物理力学性能达到国家标准;酶浸水工艺能大幅度减少中性盐和表面活性剂的使用,并将工艺时间缩短一半;废液COD、BOD5接近国家二级排放标准。The histological structure,protein content,mechanical properties of beaver rabbit leather and BOD,COD,TOC of soaking waste liquor were compared with traditional soaking process.It was concluded that using protease as soaking agent could loosen collagen fibers without destroying the follicles.The mechanical properties of beaver rabbit leather meet with the national standard.The dosage of salts and surfactants in enzymtic-soaking could be greatly reduced,and soaking time could be cut in half.The COD and BOD5 in the enzymtic-soaking liquor are close to the secondary standard of national wastewater discharge.
