The design, procurement, and construction of the project were completed in a very short time, and the water was opened and reached the standard as soon as the construction was completed. The treatment scale is 5,000m³/d, and the main process of the decentralized sewage treatment equipment adopts "bio-enhanced process + MBR process", which occupies an area of more than 50% less than the traditional process, and the effluent quality is continuous and stable to meet the quasi-surface water class IV water quality standard.
