某医院污水处理碳排放量化及核减措施研究

Study on carbon emission quantification and reduction measures of sewage treatment in a hospital

医院污水处理系统作为医院建设必不可少的组成部分,设计标准与技术应用现状一致性较弱,总体建设效率、秩序有待提升。总结并利用排放因子法,以北京某综合医院为实例,从直接排放和间接排放两个方面对碳排放进行量化计算分析,核算出该医院污水处理过程中碳排放总量为575741.13kgCO_(2)/年,其中电耗、药耗和处理工艺产生的碳排放分别占到了79.95%、0.08%和19.97%。最后根据核算结果与医院污水处理系统的特点,提出以安全达标排放为最终处理目标,优化处理工艺,结合标准避免过度设计。

Hospital sewage treatment system is an indispensable part of hospital construction.The consistency between design standards and technology application is weak.Overall construction efficiency and order need to be improved.This paper summarizes and uses the emission factor method.Taking a general hospital in Beijing as an example,the carbon emissions were quantified and analyzed from the aspects of direct and indirect emissions,the total carbon emissions in the sewage treatment process of the hospital were calculated to be 575741.13 kg CO_(2)/a.The carbon emissions from electricity consumption,drug consumption and treatment process accounted for 79.95%,0.08%and 19.97%,respectively.Finally,according to the results of the accounting and the characteristics of the hospital sewage treatment system,the final treatment goal is proposed to meet the safety standards,optimize the treatment process,and avoid excessive design in combina-tion with standards.
