摘要
亚麻沤制过程中产生的混合废水水质:COD为5000~8000mg/L,pH值为4.5~5.8,采用"气浮/氧化沟/稳定塘"组合工艺处理后,系统出水COD≤50mg/L,各项指标均优于设计标准;再经稳定塘/煤渣滤池深度处理后,可直接回用于沤麻生产,实现了企业内部水资源的良性循环。
The characteristics of mixed wastewater produced in the process of flax retting were:COD 5 000 ~ 8 000 mg/L and pH 4.5 ~ 5.8.After the wastewater was treated by using air flotation / oxidation ditch / stabilization pond process,the effluent COD from the system was less then 50 mg/L with all indexes superior to the design criteria.The effluent,after further treated by stabilization pond / cinder filter process,might be reused for flax retting,and thus achieving benign circle of water resources within the enterprise.
