Purification Effect of Potamocorbula laevis on Aquaculture Wastewater
摘要
Abstract
[Objective] To study the purification effect of Potamocorbula laevis on tail water of shrimp culture in greenhouse,and determine the breeding density of Potamocorbula laevis during purification of wastewater.[Method]4 breeding densities (0.5,1.0,2.0,3.0 ind/L) and 1 blank control (CK) were set up,each treatment was repeated 3 times and cultured for 4 d.During the experiment,the water was not changed,and no bait was put into the feed.The removal efficiency of nitrate,NH4+-H,TP and TN in aquaculture wastewater was determined by different treatment.[Result] The 4 culture densities of Potamocorbula laevis have significant removal effects on ammonia nitrogen,TP and nitrate (P <0.05).Among them,the purification effect of 1.0 ind/L treatment was the best,and the removal efficiency of nitrate in wastewater was 62% ± 15.06%.The removal efficiency of NH4+-H was 48% × 9.41%.The removal efficiency of TP was 99% ± 17.78%.The removal efficiency of TN was 60% ± 3.74%.The removal efficiency of CK was the worst,and the removal rates of nitrate,NH4+-H,TP and TN in wastewater were 15% ± 3.36%,16% × 0.58%,38% × 6.86% and 33% × 1.58%,respectively.[Conclusion] The optimum culture density of Potamocorbula laevis was 1.0 ind/L.关键词
