摘要
为了降低污水处理厂能耗,采用响应面Box-Behnken设计,考察进出水COD浓度、氨氮浓度、总氮浓度与吨水电耗之间的相应关系.结果表明,在普适工况下,不改变COD、TN的出水浓度,将出水NH4+-N浓度调至3.7-5 mg/L或不改变NH4+-N、TN的出水浓度,将出水COD浓度调至38.6-50 mg/L,可使电单耗降低5％以上.在典型工况下,不改变NH4+-N、TN的出水浓度,将出水COD浓度调至47.16～50 mg/L,可使电单耗降低5％以上.此结果可为水厂节能降耗提供一定的理论借鉴与技术支撑.
Abstract
In order to reduce the energy consumption of wastewater treatment plant,the study investigates the relationship between COD concentration,ammonia nitrogen concentration,total nitrogen concentration and power consumption per ton of water with Box-Behnken design.The results show that,under the universal working condition,the effluent NH4+-N concentration is adjusted to 3.7～5 mg/L or without changing the effluent concentration of COD and TN.When the effluent COD concentration is adjusted to 38.6～50 mg/L,the power consumption can be reduced by more than 5％.Under typical working conditions,the effluent concentration of NH4+-N and TN is not changed,and the effluent COD concentration is adjusted to 47.16～50 mg/L,which can reduce the power consumption by more than 5％.The results can provide some theoretical reference and technical support for energy conservation and consumption reduction in water plants.
