摘  要：
对罗氏沼虾(Macrobrachium rosenbergii)育苗后的废海水生物净化及重复使用进行研究。采用自行设计的整体式生物过滤器,通过生物膜处理废水。结果表明:处理后的废海水中的NH4+-N和NO2--N分别为0.47~1.21 mg/L和0.036~0.100 mg/L,符合罗氏沼虾幼体生长要求。2008年试验池水体12.76 m3,育苗各阶段使用50%~80%净化海水,虾苗产量达8万尾/m3,成活率96.2%,虾苗规格0.90 cm,与原配制海水无明显差异,节约净化海水57.52%。

摘  要：
The artificial sea water is widely used in Macrobrachium rosenbergii larvae culture in freshwater regions.In Huzhou,more than 8 000 tons of artificial sea water are used and discharged into the water ways around,causing a serious water and soil pollutions.In this paper,the author studied on reuse of waste water discharged from the larvae culture ponds.A bio-filter set designed by author was used for purification.The recirculation treated water was reused in M.rosenbergii larvae culture.The results showed that the bio-filter set could effectively remove the NH+4-N,NO-2-N and other harmful substances in waste water.The NH+4-N,NO-2-N in recycled water could reach to 0.47~1.21 mg/L and 0.036~0.100 mg/L respectively,fitting the requirements for M.rosenbergii larvae growth.This bio-filter set was successfully used in larvae tanks of M.rosenbergii larvae farm in Huzhou in 2008,saving about 57.52% artificial sea water.The survival rate of larvae was 96.2%,with the production of 80 000 ind./m3 larvae sized of 0.90 cm.It indicates that bio-filter set can effectively used for purification of discharged waste from M.rosenbergii larvae culture,which can be reused for M.rosenbergii larvae culture.
