英文摘要 | In recirculating aquaculture systems (RASs),the effective treatment of aquaculture tailwater is essential to maintain the health of the RAS.This study investigated the optimal time and method for tailwater treatment during three periods of the aquaculture of the Litopenaeus vannamei:nursery (0–26 d),middle (27–57 d),and later (57–104 d).The variation of several water parameters during the dissolution of total suspended solid (TSS) in tailwater,applied with the effects of ozone on the microorganism and water quality parameters were investigated.Results showed that the TSS concentrations in tailwater decreased with time,although not significantly (P>0.05),whereas total ammonia nitrogen (TAN),nitrite(NO_2~--N),and nitrate (NO_3~--N) increased significantly (P<0.05).Therefore,TSS should be removed from the tailwater as early as possible,being most optimal within 4 h.Ozone removed 38.24%–48.95%of TSS,17.78%–90.14%of TAN,and 87.50%–98.90%of NO_2~--N after 4 h of treatment.However,it resulted in the significant accumulation of NO_3~--N.Moreover,the total number of Vibrio and bacterial counts in aquaculture tailwater was reduced completely by ozone within 4 h.Thus,these results provided technical details and data support for the effective treatment of tailwater from shrimp RAS. |
