| titleOfInvention | Livestock and poultry breeding wastewater purification system |
| abstract | The utility model relates to a livestock and poultry breeding wastewater purification system, which belongs to the technical field of sewage treatment, and adopts a pretreatment unit, a secondary biological treatment unit and a deep treatment unit which are connected in sequence, wherein the pretreatment unit is a grating pond, an adjusting pond and a coagulating sedimentation pond to remove suspended substances in the sewage; the secondary biological treatment unit comprises a preposed anoxic tank, an anaerobic tank and an aerobic filter tank; deep treatment: the advanced treatment unit comprises a biological oxidation pond and an artificial wetland unit. TheThe system can improve the denitrification effect and simultaneously realize the removal of phosphorus and improve the wastewater treatment efficiency, thereby solving the problem of A of the existing sewage treatment 2 The problems of insufficient denitrification carbon source and mutual restriction between denitrification and dephosphorization functions in the O-MBR process are solved, and the biological oxidation pond and artificial wetland technology are combined, so that the livestock and poultry breeding wastewater is ensured to be discharged up to the standard. |
