【摘要】 本文采用物化和生物法对皮革再生生产废水处理进行了试验研究并扩大到生产实际应用。结果表明,采用石灰乳中和混凝沉淀,SS 法除率达90%以上,COD_cr去除率50%～60%；再进一步用二段煤渣为填料的生物接触氯化法处理,COD_cr去除率达90%以上,BOD₅去除率为95%以上．更多还原

【Abstract】 Experimental study and its full-scale utilization for tannery regeneration waste- water treatment by using physio-chemical method and biochemical method have been de- scribed in the article.It is shown that the removal efficiencies of SS and COD_crcould reach 90% and 50%～60%,respectively,by using lime neutralization and coagulative precipita- tion.The removal of COD_crand BOD₅ could achieve 90% and 95%,respectively,followed by two-stage biological contact oxidation process where coal cinder was used as packing materi- al.更多还原
