The Application of Integrated Equipment with Solar-power in Rural Sewage Treatment
Taking a village in environmental sensitive area of Tai Lake Basin as an example, an integrated waste water treatment equipment with solar-power was applied for treating rural sewage. Operating and monitoring data for 6 months showed that the ratio of actual power consumption to generated photovoltaic power capacity was 54.3%, which indicated that the solar power system can effectively meet the power required for the sewage treatment process. A/O-BF integration technology was used in sewage treatment section. The monitoring results showed that the effluent can stably meet the first grade standard A of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918—2002).The device was stable, low failure rate, no drug dosing and no running costs, which was suitable for application in rural areas of Tai Lake Basin.
