| In recent years,water quality protection has received a great deal of attentions.Poultry wastewater is one of the major domestic water pollution sources,if the direct discharge will cause the river water pollution.At present,China’s livestock wastewater is mostly treated by the three-stage wastewater treatment system.Howver,this wastewater treamtent system has high construction cost.On the other hand,if poultry wastewater treatment system can be properly used,a lot of costs can be saved.In this study,we use patented technology to treat livestock wastewater bwith biotechnology.The main purpose of this study is to measure the removal rate of the system under different pollutant loads,and to discuss the situation of removal rate.The results showed that the average pH value of the effluent flow was 7.76.The mean temperature of effluent water was 27.5 ℃;the removal rate of COD was 93%;the average removal rate of SS was 95%;the average removal rate of BOD was 96%;the removal rate of NH3-N was 85%and the removal rate of TP was 87%.Currently,to reduce resources waste is a common goal of the world.In the particular case of the wastewater treatment and operation,in good circumstances,a relatively improved the removal rate can be realized through the newly developed treamtent system.Meanwhile,this new system has lower production cost and smaller sp ace occuaption,which is consistent with global common goal of the world. |
