The Dongcun classification project mainly includes sorting and recycling systems, anaerobic biogas generation systems, etc., to make garbage disposal harmless and resourceful. In the sewage treatment project, we use multiple electromagnetic flowmeters of our company, which are mainly used in the flow monitoring of each process link of the sewage treatment plant.
