Using upflow activated carbon process and a combination of submerged ultrafiltration membrane and sand filtration process,a large Chinese sturgeon exhibition water tank was circulation treated.The total displayed water volume is 10 000 m3,with a designed water circulation cycle of 1.5 h/time,a treatment capacity for the maintenance system is 1.6×105 m3/d.After treatment,the turbidity of the effluent was stably kept below 0.1 NTU,ensuring that the exhibition water is clear and transparent and the display effect is good.This design provides engineering case support for the application of submerged ultrafiltration membrane technology in the treatment of aquaculture wastewater.
