摘要 以不同浓度的畜禽养殖废水为对象,研究藻菌体系对废水中的NH4+-N、TP和COD的去除效果。结果表明:藻菌体系对不同浓度的畜禽养殖废水的处理效果不同,当废水中NH4+-N、TP和COD浓度分别小于44.4 mg/L、6.4 mg/L和500 mg/L时,藻菌微生物的生长速度快、生物量大,对废水处理效果好;当处理时间为6 d时,NH4+-N、TP和COD的去除率分别大于90%、84%和80%,该实验结果为构建高效藻类塘提供理论依据。 With different concentrations of livestock wastewater,the removal efficiency of NH+4-N,TP and COD in wastewater algae bacteria system is investigated. The results showed that the removal efficiency of the algae bacteria system varies on different concentrations of livestock wastewater. When the concentration of NH+4-N,TP and COD in wastewater was less than 44. 4 mg /L,6. 4 mg /L and 500 mg /L,the algae bacteria microorganisms had faster growth rate,larger biomass and better wastewater treatment efficiency. When the treatment time is 6 d,the removal efficiency of NH+4-N,TP and COD is greater than 90%,84% and 80% respectively. The experimental results provide a theoretical basis for constructing high rate algal pond.
