摘　　要：针对屠宰废水中的血水难以絮凝处理的问题 ,首先对其进行了适当的变性处理 ,然后将各段废水集中进行了絮凝处理研究 ,考察了多种絮凝剂和处理效果。结果表明 ,屠宰废水经过变性预处理后采用硫酸亚铁和氧化钙复合絮凝剂处理后 ,可得到理想的处理结果 ,出水COD可达187.4mg/L,色度值为75度。此方法简便、高效、有很好的环境和经济效益。According to the problem that slaughterhouse or abattoir waste blood water was difficult to carry on flocculation treatment, this article, firstly made experiments on this wastewater's denaturation of protein, and then researched on the flocculation of every mixed wastewater. As the same, the treatment effect of various flocculations were studied. The result showed that after dernaturation of protein pre-treatment with ferrisufas and polyacrylamide as a compound flocculant,the satisfactory outcome of treatment was achieved, that is, COD reached up to 187.4mg/L, transmittance became as high as 88.5% and chromatic degree is 75.The method is convenient, high-efficent and economic.
