Wind-solar complementation drives the development of bio-physical coupling multi-stage treatment system for rural sewage
At present,the biggest challenge in the application of clean energy in the field of sewage treatment is that it is susceptible to weather conditions,resulting in unstable output of electric energy and continuous normal operation of the load.Therefore,in order to ensure the stable output of electric energy and the normal operation of facilities,the wind-solar hybrid battery energy supply mode was adopted,and the seasonal complementarity of solar and wind energy was determined by monitoring and analyzing the changes of solar and wind energy intensity in different seasons.On this basis,an integrated system of wind-solar complementary driving bio-physical coupling multi-stage treatment facilities for rural sewage was designed,and the coupling of biological and physical technology was used to achieve efficient and stable removal of pollutants in sewage.The results of 202 days of continuous operation showed that through the efficiency analysis of the system,it was proved that wind energy can supplement solar power generation,effectively improve the stability of the power supply system,realize the stable power output of the power generation system,and the energy utilization rate can reach more than 90％.The removal rates of COD,NH4+-N,TN,TP and SS in sewage were 86.73％±2.89％,87.82％±6.59％,75.63％±11.79％,78.65％±6.39％,94.59％±0.89％,respectively.The effluent met the first-level standard of the Inner Mongolia Autonomous Region Pollutant Discharge Standard for Rural Domestic Sewage Treatment Facilities(Trial)(DBHJ/001-2020).The results proved that it was feasible to use wind-solar energy complementarity to drive biophysical coupling to treat rural domestic sewage.
