摘要：

在“双碳”目标下，创造性提出将石化企业工业用水、污水排放、污水收集与输送、污水处理与回用作为一个完整的系统，综合考虑生产装置排污特点、污染物的产生及排放路径，构建污水系统污染物溯源追踪平台，精准分析各污染物的排放及污染物排放总量，进行污染源定位，实施源头优化与过程减排，并以某石化企业为例，展示该平台在实际操作中的运用。结果表明，应用污染物溯源分析和过程减排技术，可实现对污水排放情况的在线监测、运行分析、污染源溯源及源头削减，有效降低进入污水处理厂的水量与污染物浓度，为污水处理厂优化运行和节能降碳提供条件。

Abstract:

Under the “dual carbon” goal, the article creatively proposed industrial water use, sewage discharge, sewage collection and transportation, sewage treatment and reuse of petrochemical enterprises should be treated as a complete system. Taking into account the characteristics of pollution discharged from production units,and the generation and emission path of pollutants, a sewage system pollutant traceability analysis platform was constructed to accurately analyze the discharge of various pollutants and total emissions of pollutants, realize pollution source localization, and optimize the source and process emission reduction. Taking a certain petrochemical enterprise as an example, the platform application in the actual operation of the sewage system was demonstrated. The results indicated that the application of pollutant tracing analysis and process reduction technology could achieve online monitoring, operational analysis, pollution source tracing, and source reduction of sewage discharge, which effectively reduced the water quantity and pollutant concentration entering sewage treatment plants, and provided conditions for optimizing operation and energy conservation and carbon reduction.

Key words: carbon peaking, carbon neutrality, sewage treatment, traceability analysis, process emission reduction
