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
