Recently, the reporter learned from the Jiuzhaigou County Environmental Protection Bureau that the province's first solar micropowered sewage treatment pilot project was completed in the county's Majia Township and has now officially entered the trial commissioning phase.
It is reported that in recent years, due to financial difficulties in the local grassroots, the supporting funds for infrastructure construction in remote rural areas have been unable to be guaranteed. Environmental infrastructure has also been relatively backward. Domestic sewage has not been treated in time and it has caused serious pollution to surface water. In order to protect the ecological environment, and further explore a new model for the treatment of sewage in remote villages. Since last year, the project has been selected under the guidance of the provincial environmental protection department with strong financial support and careful technical guidance. The final site is located in Shengnan New Village, Majia Township, Jiuzhaigou County. After nearly five months of construction, the construction and equipment installation of the entire pilot project has been successfully completed.
It is understood that the pilot project has a total investment of nearly 400,000 yuan, and its structure is mainly composed of inlet grille wells, anaerobic tanks, anoxic tanks, sedimentation tanks, and wet pools. The process used for the centralized collection of domestic sewage first enters the grid wells in the sewage treatment station. After the suspended solids in the sewage are treated by filtration, they are then dephosphorized in the anaerobic tank, solar aerobic tank and anoxic tank. Ammonia nitrogen, and finally enter the solar aerobic reaction pool, the use of solar photovoltaic panels to provide power, the release of metal ions in the sewage into optoelectronics, and ultimately sewage treatment to meet the national standards for emissions.
