Abstract

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.
