Research and Application of Ecological Rural Sewage Treatment Facilities Based on Internet of Things

In view of the current problems existing in the rural integrated sewage treatment facilities, such as difficulty in maintenance, difficulty in long-term and stable operation, difficulty in site selection and bad smell that cause villagers’nimby, an ecological integrated rural sewage treatment facility was designed and developed based on the management and control platform of Internet of Things. The practical operation results indicated that the construction of rural sewage treatment facility and the Internet of Things management platform enabled the system to have the three-dimensional design and compact footprint, ecological shape and pleasant landscape, stable compliance, economical and practical effect, easy maintenance, remote control, intelligent and worry-free advantages. Higher pollutant removal capability was achieved by the eco-integrated rural sewage treatment facilities with polyurethane sponge filler. The average removal rates of COD, ammonia nitrogen and total phosphorus were 81.51%,74.81% and 67.10%, respectively. In addition, the effluent quality could meet the first level B criteria in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002).
