一种减少三废排放的制革方法
摘要：
本发明提供了一种减少三废排放的制革方法，该制革方法能够全面实现制革过程中减少三废的排放，通过废水回用，抑制固体物消解或溶化，重新资源化；减少废水、固物、化料的挥发，以实现减少废气的排放；具体特征在于：在浸水、浸灰、复灰、脱灰软化、浸酸铬鞣、脱脂、复鞣、中和、染色工序中独立进行操作的，本发明节约用水70%以上，节约能源20%以上；废固物的排放减少70%以上；节约化料15%-100%，并减少化料挥发对空气的污染；采用此方法能明显改善皮革的质量。
摘要（英）：

The invention provides a leather manufacturing method achieving three-waste discharge reduction. The leather manufacturing method can comprehensively achieve reduction of three-waste discharge in the leather manufacturing process. Through wastewater reuse, solids are inhibited from decomposing or dissolving and are recycled; and exhaust emission is reduced through reduction of volatilization of wastewater, the solids and chemical materials. The leather manufacturing method is specially characterized in that soaking, liming, reliming, lime removal and softening, pickling chrome tannage, degreasing, retanning, neutralizing and dyeing are conducted independently, water is saved by over 70%, and energy is saved by over 20%; emission of solid waste is reduced by over 70%; the chemical materials are saved by 15% to 100%, and pollution to air due to volatilization of the chemical materials is reduced; and by the adoption of the method, the quality of leather can be improved remarkably.
