The hazardouswaste liquid is composed of Acid-alkali waste liquid , copper containingwastewater, nickel containing wastewater, chromium containing wastewater,cyanide containing waste and landfill leachate.

The originaltreatment process is anaerobic+ anoxic +aerobic +MBR +UF +spiral RO.

Because thespiral RO is fouling seriously and could not operating normally,so the effluentquality was not up to the discharge standard.

According alongtime experimental,Meifute used the special membrane technology to reformthe project.
