摘要

摘要: 针对制药企业污水站厌氧池中的温室气体甲烷和恶臭气体,在原有水吸收-光催化-化学吸收治理工艺的基础上,改造形成水吸收-碱吸收-蓄热式焚烧(RTO)-急冷-碱吸收为主的温室气体削减协同恶臭处理新工艺。利用生命周期评价法,对废气治理工艺的环境影响进行特征化、标准化分析。结果表明,改造前、后废气治理工艺的主要环境影响均为全球变暖。通过温室气体削减量核算和经济性评估可知,工艺改造后,总温室效应潜值年削减量可达到7.53×10⁶ kg CO_2-eq,运行成本节约1.21×10⁶元。新工艺在实现减污降碳的同时,具有显著的经济和社会效益。

Abstract: In response to the environmental protection goal of "reducing pollution and carbon, collaborative governance, improving", a new process of equivalent greenhouse gas and malodorous gas treatment based on the original "water absorption-photocatalysis-chemical absorption" treatment process had been transformed into a "water absorption-alkali absorption-regenerative incineration (RTO)-quench-alkali absorption," which aimed at greenhouse gas methane and malodorous gas of the anaerobic tank in the sewage station of the pharmaceutical industry. Life cycle assessment (LCA) was used to implement characteristic and standardized analysis of the environmental impact of the waste gas treatment process. The results showed that the significant environmental impact of the original and new waste gas treatment process was global warming. Through the greenhouse gas reduction calculation and economic evaluation, compared with the original process, the new process could reach the annual greenhouse effect reduction value of 7.53×10⁶ kg CO_2-eq and an economic benefit of RMB 1.21×10⁶. The new process provided a theoretical basis for comprehensively developing the pharmaceutical industry’s environmental, technological, economic, and social benefits while achieving efficient waste gas treatment.
