摘要
介绍了造纸中段废水深度处理工艺。结合工程实例,在原有"气浮+曝气+稳定"的处理工艺后增加进水系统、芬顿系统、砂滤系统,处理后出水CODcr≤90 mg/L,BOD5≤50 mg/L,SS≤50 mg/L。经核算,吨水运行费用约为1.29元。
This paper introduces the tertiary treatment process of washing and bleaching effluent of paper industl-y.With an engineering example, the influent system, Fenton system and filter system are added in the back of the original process ＂air floatation＋ aeration＋ stabilization＂. After the treatment,the quality of effluent are： CODer ≤90 mg/L, BOD5 ≤ 50 mg/L and SS ≤50 mg/L.The adjust accounts on economics show that the operational fee costs about 1.29 RMB per ton.
