Solar energy can treat farm sewage in Tonglu, Zhejiang

On the 19th, tourists from Shanghai gave a thumbs up to a solar micro-power rural sewage treatment plant in Dipu Village, Tonglu County, and said: "This is the first time I have seen sewage treated with solar energy in the countryside."

The solar micro-power rural sewage treatment system in Dipu Village was introduced by the county from Zhejiang University. It adopts the "anaerobic + anoxic + aerobic" treatment process, uses solar micro-power technology, automatic control, and automatic operation. "This sewage treatment system uses solar photovoltaic panels to convert solar energy into electricity for sewage treatment. After the battery is fully charged, it can ensure the normal operation of sewage treatment even if it rains for 7 consecutive days." The relevant person in charge of Tonglu County introduced. The treated sewage can be reused for irrigation, and the organic sludge in the sedimentation tank can be reused as organic fertilizer after maturation.
