| Abstract: | The design scale of wastewater treatment plant(WWTP)in an industrial zone of Yunnan is 1.0×104 m^3/d.The inverted AAO technology is adopted for the secondary treatment.The biochemical tank,secondary settling tank,nitrating liquid reflow,sludge reflow and surplus sludge discharge are constructed together,which have the characteristics of small land area,low engineering cost,easy operation maintenance and convenient management.The technology of rotary filter+biological fast filtration+disinfection by ultraviolet light is used for the tertiary treatment.The design effluent quality meets the class A standard of Discharge Standard of Pollutants from Municipal Wastewater Treatment Plant(GB 18918—2002). |
