摘要
概述了当前制革行业污水的现状及各工序污水的特点,针对我国水资源短缺的现况和制革废水的特征,对制革的脱毛、浸灰、脱脂、浸酸、铬鞣等工序的废液循环利用进行了综合分析,认为在目前技术条件下,制革操作液的循环利用是实现清洁化生产的有效途径之一。经过废液的循环利用可以明显节约制革用水,降低化工材料消耗,减少污染治理成本。制革废液循环利用技术简单、易操作且成本较低,但是,也需要进行必要的产学研联合攻关,开发与废液循环系统配套的相关助剂、工艺技术、生产设备等,才可实现真正意义的制革操作液的有效循环使用。
The current status of waste water produced by leather industry and the characteristic of waste water in every process were summarized, and the wastewater recycling in unhairing, liming, degreasing, pickling, chrome tanning were analyzed for the purpose of the recycling of tannery wastewater. The recycling of tannery wastewater was one of effective ways to achieve clean production. The leather wastewater can be obviously saved, chemical material consumption and pollution control costs are reduced by recycling of wastewater. The recycling technology of tannery wastewater is simple, easy operation and low cost, but also need the necessary research about related additives, technologies and production equipment.
