An example of wastewater treatment project in chip industrial park
In view of the characteristics of wastewater in chip industry,such as complex composition,high fluoride concentration and containing a variety of harmful substances,chemical precipitation-hydraulic acidification-AO/MBR-RO process was adopted for its treatment.RO concentrated water was treated by combined process of ozone catalytic oxidation-AO(MBBR)/MBR,at the same time,Fenton advanced oxidation technology and fluoride removal resin system were also designed as assistance.The effluent water quality reached class Ⅲ discharge standard(ρ(TN)≤15 mg/L)in GB 3838-2002 Surface water environmental quality standard,and also met the requirement of wastewater reuse.The design parameters and equipment configuration of each process unit in the sewage treatment plant were introduced in detail,and the technological characteristics were summarized and analyzed.
