| Abstract: | In this paper,the purification effects of different rice-fish farming systems on aquaculture wastewater were studied through enclosure experiments.Results showed that paddy field,rice-crayfish and rice-crab farming systems all had significant purification effects on aquaculture wastewater,and there was no significant difference among different systems(P>0.05).The maximum removal rates of ammonia nitrogen,nitrite nitrogen,TN and TP were 67.48%,78.13%,37.97%and 53.05%,respectively.I Mn and suspended solids in aquaculture wastewater were reduced to a minimum in 1~2 days,ammonia nitrogen was in 2~4 days,TN was in 4~8 days and TP was in 8~16 days.In addition,the co-culture of crayfish and crab in paddy fields had no significant disturbance on the purification of aquaculture wastewater. |
