摘要
Guizhou province has built 66 town sewage treatment plants, the statistics of the construction, operation, and energy consumption statistics show that town sewage treatment plants in Guizhou are based on small ones below 10,000 m3 / d ,the common treating process is mostly oxidation ditch.Most of the A / O process and HASN craft, pipe network are mostly mixed-flow, the average load rate of sewage treatment plants is 76.87 percent. Microwave treatment process is the most efficient way to remove COD and SS, biological aerated filter is the most efficient way to remove BOD and ammonia, activated sludge process is the best way to remove phosphorus. With the increasing scale of the operating, costs are reduced, so sewage treatment plants should choose technology and scale to adapt to local conditions, improve the operation of the facility and enhance the pollutant removal rate effectively.
