Abstract:
The first phase capacity of the wastewater treatment plant (WWTP) in an industrial park of Weihai is 2×104 m3/d, and 60%-70% of the influent water is refractory industrial wastewater. The influent quality is determined reasonably through the analysis of the current influent water quality and the total capacity is expanded to 5×104 m3/d. The design effluent should meet the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). The combined process of MBBR, magnetic coagulation sedimentation tank, denitrification filter, ozone catalytic oxidation tank, and V-type filter is adopted. The actual operation results show that the effluent quality reaches the standard stably.
