以电导率为分质指标，对纱线筒染废水进行“清浊分质”收集，并对收集到的轻废水进行接触氧化、超滤、反渗透处理；对重废水进行水解酸化、接触氧化、混凝沉淀处理，最后对轻废水减缓膜污染方面进行优势分析。结果表明：轻废水经处理后，ρ（ COD ）＜17 mg/L、色度1倍、ρ（ Fe3＋）≤0.1 mg/L、ρ（ Mn）＝0.05～0.09 mg/L、硬度为50～80 mg/L，水质优于印染用水要求，并且能够减缓膜系统污染速率；重废水经处理后，ρ（ COD ）＜50 mg/L、ρ（ NH3-N ）＝1.71～2.93 mg/L、色度小于50倍，满足重点工业行业废水排放要求；表明采用以电导率为指标的废水分质收集与处理方法，自动化程度高、分质准确，有效缓解了后续处理负荷，减缓了膜污染，提高了废水回用率。

In this study , the cotton yarn-package dyeing wastewater was collected , separated , and sorted with conductivity chosen as an indicator of separated collection .The collected light wastewater was treated with contact oxidation, ultrafiltration, and reverse osmosis , and the heavy wastewater was treated with hydrolytic acidification , contact oxidation , and coagulation sedimentation .Finally, the advantage of light wastewater in reducing the membrane fouling was analyzed .The results are as follows:For the light wastewater ,ρ( COD) <17 mg/L, chroma was 1 time,ρ( Fe3+) ≤0.1 mg/L,ρ( Mn) ranged from 0.05 to 0.09 mg/L, and the hardness ranged from 50 to 80 mg/L, indicating that the water quality exceeded the requirements of printing and dyeing and can reduce the membrane fouling rate.For the heavy wastewater , ρ( COD) <50 mg/L, ρ( NH3-N) ranged from 1.71 to 2.93 mg/L, and chroma <50 times, which met the emission standards of industrial wastewater .This study shows that the method of separated collection with conductivity as the indicator has a high degree of automation and accuracy , and can relieve the burden of the sorting process , slow down the membrane fouling , and improve the reutilization rate of wastewater .
