基于统计学方法的城市污水处理厂能耗变化研究

Research on Energy Consumption Changes of Urban Sewage Treatment Plants Based on Statistical Methods

采用统计学方法统计分析单位水量耗电量随进水量等级、进水COD、COD处理总量的变化规律。结果表明:随进水量等级从5级变到10级,单位水量耗电量随之减小;COD处理总量越高,单位水量耗电量越低。单位水量耗电量高值在进水量等级5~7级、进水COD浓度占比等级10~11级、COD处理总量占比等级4~5级交汇处。单位水量耗电量低值在进水量等级为8~10级、且进水COD浓度占比等级为8~13级与COD处理总量占比等级为7~13级交汇处的COD处理总量占比等级较大的范围。

This study adopts statistical methods to statistically analyze the unit wasterwater volume consumption with the level of wasterwater consumption with wasterwater intake,wasterwater inlet COD,and COD processing.The results show that:from level 5 to 10 with the level of wasterwater,the amount of electricity consumption consumption in the unit of wasterwater decreases;the higher the total amount of COD processing,the lower the power consumption of the unit water.The high value consumption of unit water consumption is at the level of 5-7 in the wasterwater intake level,the proportion level of the COD concentration of wasterwater inlet,and the total proportion of COD processing is 4-5.The low value of electricity consumption per unit of wasterwater is mainly concentrated in the range of the larger value total COD treatment proportion where the influent level is 8-10,and the influent COD concentration level is 8-13 and the total COD treatment proportion is 7-13.
