Abstract: |
To explore the higher efficient technology for purification of recycling aquaculture water, a novel integrated biology-ultrafiltration (UF) membrane device combining the water spinach, immobilized microorganism, polypropylene filler and poly vinyl chloride (PVC) hollow fiber UF membrane was designed and used for treating water in practically raising cyprinus carpio haematopterus. By 36 days’ operation under proper condition of this device, the COD, NNH3, TN and TP concentration was reduced lower than 39 mg/L,1.2 mg/L、7.0 mg/L and 1.54mg/L,respectively. These date indicated that the ideal effect of the device in removing the pollutants generated in fish tank. As well, the excellent fouling resistance of PVC UF membrane and inner side-crossing filtration mode guaranteed the stable flux of the corresponding PVC membrane. These result suggested that the designed biology-PVC UF membrane combined device should be of one of the new applicable technology via further optimizing in material and running process. |
