【摘要】：为实现造纸行业各部门用水结构的优化,采用工业水足迹分析方法,明确了造纸行业工业水足迹评价的系统边界,构建了造纸行业工业水足迹核算框架,并选取山东省某典型造纸企业为研究案例,计算了该企业工业水足迹、节水减排后水足迹削减量及贡献率.结果表明:1该造纸企业蓝水足迹为55.90 m~3/t、灰水足迹为21.80 m~3/t、隐含水足迹为5.65 m~3/t.2通过进行清洁生产审核,可以节约蓝水足迹1 184 209 t,隐含水足迹1 207 184 t,灰水足迹785 334 t,共节约工业水足迹量为3 176 727 t.3工艺技术改进和中水回用技术对企业节约水足迹的贡献率分别为38.88%、42.00%,对节约水足迹总的贡献率为80.88%.研究显示,工艺技术改进和中水回用对节约工业水足迹的贡献率最大,造纸企业节水减排的重点应是提高中水回用率,可通过加强技术改造、引进先进设备完成.
[Abstract]:In order to realize the optimization of structure of water use departments in papermaking industry, the industrial water footprint analysis method, the system of paper industry Water Footprint Evaluation boundary, constructed the paper industry industrial water footprint accounting framework, and a typical paper-making enterprises in Shandong province were selected as the study case, the industrial water footprint, water saving and emission reduction after the water footprint cut the reduction and contribution rate were calculated. The results showed that: 1 of the paper-making enterprises in the blue water footprint is 55.90 m~3/t, the gray water footprint is 21.80 m~3/t and the hidden water footprint is 5.65 m~3/t.2 through cleaner production audit, can save the blue water footprint of 1184209 t, 1207184 t hidden water footprint, grey water footprint was 785334 T, total industrial water saving footprint reuse technology for the enterprise to save water footprint is 3176727 T.3 technological improvement and water contribution rate were 38.88%, 42%, contribution to the conservation of water footprint rate is 80.88%. Research shows that technological process improvement and reuse of recycled water have the largest contribution rate to saving industrial water footprint. The key point of water saving and emission reduction for paper enterprises is to increase the utilization rate of recycled water, which can be accomplished by strengthening technological transformation and importing advanced equipment.
