硫酸渣资源化及其以废治废技术研究

RESEARCH ON RECYCLING TECHNOLOGY AND WASTE WATER TREATMENT WITH

  • 摘要: 根据粤西某硫酸厂硫酸渣的物理、化学性质特征,研制了筛分分级-重力分选-重组分浮选脱硫回收高质铁-轻组分浓缩脱水-化学聚合制备废水处理剂的联合工艺.经处理从硫酸渣中获得18.61%的水泥掺料、49.76%品位为63%的铁精矿以及水处理剂等产品,铁的资源化率达到98.23%,几乎无废物产生,使硫酸渣生产区域的环境质量得到良好的改善.以低品位含铁硫酸渣制备的复合混凝剂,处理CODcr8000mg/L的高浓度石化废水时,CODcr的去除率为93%,达到以废治废的效果.

     

    Abstract: Based on the physical and chemical characteristics of the sulfuric acid residue from a sulfuric acid manufacture in the west of Guangdong Province, a flow sheet was developed with sieve classification, gravity concentration and pyrite flotation as well as coagulant making by chemical aggregation from light fraction of gravity separation. A result of 18.61% admixture for cement slurry, 49.76% iron ore concentrate with a grade of 63%Fe and coagulant for waste water treatment had been obtained from the slag by applying a new process. The rate of slag recycling was up to 98.23% leaving only little waste, and thus the pollution caused in the area was controlled. The removal rate of CODcr was 93% when the developed coagulant was used in the treating petrochemical waste water.
