Paper Title:
Study on the Advanced Treatment and Reuse of Dyeing Wastewater Using Polyamide Nanofiltration Membrane
  Abstract

The microfiltration (MF) and nanofiltration (NF) integrated membrane technologies were used in the advanced treatment of dyeing wastewater. The ZrO2 MF membrane was used to remove colloidal species from the wastewater before NF. The effects of permeate flux, CODCr rejection, the removal effects of ammonia nitrogen and total phosphorus by polyamide NF membrane were investigated. The results indicated that the turbidity removal efficiency was 76.7%~95.0%. CODCr rejection was range from 33.3% to 54.9% by MF. After the process of NF, CODCr rejection was between 66.65% and 91.18%. The removal effects of both color and turbidity were 100%. The value of pH was 6~7. The CODCr was smaller than 60mg•L-1. The value of ammonia nitrogen was smaller than 7mg•L-1. The value of total phosphorus was smaller than 0.5mg•L-1. It came up to the quality standard of recycling raw water for industrial uses. It can be used as the water for industrial.
