已经开发出一种使鞣制废液能循环利用的铬鞣工艺。最常用的铬盐被高度隐匿和碱化物所取代。这种替换可省去盐碱化操作,并防止pH值的变化和中性盐浓度在鞣制废液中的大量增加。因此,鞣制废液可被多次重复使用。研究表明鞣制废液中的最佳... 详细信息

已经开发出一种使鞣制废液能循环利用的铬鞣工艺。最常用的铬盐被高度隐匿和碱化物所取代。这种替换可省去盐碱化操作,并防止pH值的变化和中性盐浓度在鞣制废液中的大量增加。因此,鞣制废液可被多次重复使用。研究表明鞣制废液中的最佳铬盐浓度在10%到12.5%之间。鞣制废液可重复使用次数取决于要被制造的皮革粒面质量。在最好的情况下,每公斤皮革制品可节约用水18L,这意味着比正常情况节省90%的用水。

要本研究采用一种可替代牛皮制革工艺传统脱毛方法的新试验。本工艺采用过氧化氢代替传统的硫化钠作为脱毛剂应用于毛回收和浴液循环利用过程。我们将传统工艺和新工艺制造的皮革性质进行比较，结果说明二者具有相似的物理、化学以及感官性质。然而，从环保的观点出发两者的差别是巨大以及明显的。这其中包括了水的消耗量减少（大约降低70％）、化学需氧量的减少（大约降低35％）、生物毒性的减少（98％）以及总凯氏氮（50％）。不仅如此，新工艺也消除产生硫化氢的可能性，选极大的改善制革工人的工作环境的安全性。假定以工艺中排放大量污水以及化学污染物作为标准．绝对值的减少代表着巨大的工艺进步。本文还对新工艺做了经济的评估，结果表明新体系较传统工艺节约16％.

在制革过程中，所有工序都会产生废弃物，将其排放到周围环境中，将会产生废水、废液、固体废弃物，以及废气和臭气等。在大生产规模上，本文研究了一种新的鞣制方法来替代传统的鞣制方法。该新方法采用无浴鞣制，并在鞣制后期将温度升得很高。鞣革性能的测试结果表明，对于传统和新方法鞣制的革，它们具有相似的物理、化学和感观性能。但是，从环境角度来看，两种方法的差异还是很大的，例如，新鞣制方法不需使用清洁水，与传统方法相比，其残留浴液减少75％，铬排放量减少91％，氯化物的排放量减少94％。另外，成本估算结果表明，与传统方法相比，新方法的生产成本降低32％。

制革工艺中会产生大量含三价铬、氯化物的废液。本文阐述了一种新型制革工艺，以提高化学试剂使用效率来改善制革厂环境。该工艺研发了一种无浴系统，其中氯化钠含量最低，铬盐用量减少，提高最终鞣制温度到55℃。所制得革性能与传统工艺所得革性能相似，然而，新工艺却减少了97％的剩余铬量以及95％的氯化物排放，此外，还节省了100％的水，约78％的NaCl和32％的Cr2O3。从而较之传统工艺提高了55％的经济效益。

转鼓鞣制过程需要消耗大量的水和化学试剂,它们大多最终成为废水。本文探讨了一种可以在工业化条件下的替代传统浸酸铬鞣法的鞣革新方法。新方法用芳磺酸代替甲酸和硫酸,由于不用浴液,因此可以大幅度的减少盐和红矾钾盐的添加量,并可以提高鞣制过程最后阶段的温度。从环保角度看,新方法有更大的优势。例如,鞣革时无需添加浴液,另外,氯化物和铬的排放量分别减少了94%和99%,同时,残留浴液也减少了75%。新方法的经济效益也比传统方法节省42%。
