Abstract:

The treatment of pesticide wastewater pollution has been carried out by using nanofiltration membranes，Type DK and Type NF90， and their applicability and efficiency have been studied. The treatment effect and efficiencyof wastewater with different concentrations by using the two types of membranes have been investigated. Theeffect of nanofiltration membranes on the rules of the removal rates of COD， TP， NH3-N， conductance and the appropriateranges are gained. The results from this study show that using the combination of DK and NF90 couldstrengthen application supority of each type of nanofiltration membrane and improve the treatment efficiency suitablefor treating imidacloprid pesticide wastewater with high concentration and salinity.

Key words: nanofiltration, pesticide wastewater, membrane separation

摘要：

选用DK型、NF90型纳滤膜治理农药废水污染,并对其适用性与应用效果进行了研究。考察了两种膜对不同料液浓度废水的治理效果与处理效率,得到纳滤膜对COD、TP、NH3-N、电导率的去除规律及其适用范围。试验结果表明,将DK型与NF90型纳滤膜组合可发挥不同膜的应用优势、提高处理效率,适用于治理高浓度、高盐分的吡虫啉农药废水污染。
