Study on Purification and Culture Effect of Circulation Water Culture Systems of the Wetlands + Ecological Ditch
Abstract：[Objective]In this experiment, through the detection of the removal rate of water quality indicators, and the comparison of ecological and conventional areas Of the fish grow, to master the law of water changes. In order to provide a more scientific basis for better healthy breeding, and brought great hydrological and economic benefits. [method]Through a period of three months of testing about the ecological ditches, wetlands and other related water. Including the TP, the NH3-N,the NO2—N, the TN, the PO43- and the CODMn,. The monthly removal rate of these indicators was analyzed to evaluate the purification and breeding effects of the farming system. we make the ecological breeding model was compared with the conventional pond culture pattern near the park, and study on the breeding model of the grass carp, mixed carp, silver carp, bighead carp and herring was carried out..[result]The average removal rate of total phosphorus (TP) was 56.08%, the overall trend was stable; the average removal rate of permanganate (CODMn,) was 8.04%, the overall trend changed greatly; the average removal rate of NH3-N was 43.82%. The average removal rate of total nitrogen (TN) was 32.22% and the overall trend changed greatly. The average removal rate of NO2—N was 45.08%, the overall trend was more stable and the later fluctuated. The average removal rate of phosphate (PO43-) was 51.64%, and the overall trend fluctuated greatly.
