- Abstract:
- The design capability of wastewater treatment station in a breeding base is 300 m3/d, which adopts the combined process of pretreatment, first stage coagulation sedimentation, anaerobic system, SBR, A/O, MBR, second stage coagulation sedimentation, ecological pond, and disinfection. The design parameters of main structures and equipment are introduced and the operational performance and cost are analyzed. The process has the characteristics of strong impact load resistance, stable operation, convenient operation and maintenance management. After six months of operation, the results show that the effluent COD, BOD5, NH3-N, TP, and SS are 58 mg/L, 13 mg/L, 1.7 mg/L, 0.45 mg/L, and 19 mg/L, respectively, which completely meet the requirements of level Ⅰ criteria in Integrated Wastewater Discharge Standard (GB 8978-1996). The tail water is discharged to the agricultural irrigation ditch on the west side, which is used to replenish water for paddy field crops.
