Amid the dual pressures of environmental protection and energy crises, anaerobic biogas power generation—a highly efficient and eco-friendly energy technology—is increasingly becoming a crucial pathway for enterprises to achieve sustainable development. By processing organic waste through anaerobic fermentation to produce biogas that drives power generation units, this method not only generates electricity and heat but also effectively reduces environmental pollution from waste, achieving multiple benefits simultaneously. As the core approach for resource utilization of organic waste, biogas power generation plays a pivotal role in realizing the “ dual carbon ” goals. However, exhaust gases from biogas power generation units contain nitrogen oxides (primarily nitric oxide NO and nitrogen dioxide NO₂) and hydrogen sulfide. If discharged without proper treatment, these substances pose serious threats to human health and ecosystems. In such cases, professional exhaust gas treatment solutions become particularly critical.
Traditional biogas power generation units face dual challenges in exhaust gas treatment: excessive nitrogen oxides (NOx) emissions, ammonia slip, and secondary pollution. The combustion temperature of biogas units fluctuates significantly, with NOx concentrations often exceeding 200 mg/m³ – far surpassing the national standard (NOx ≤50 mg/m³ for gas turbines). Traditional SCR denitrification systems achieve only 40%-60% efficiency, while excessive ammonia injection results in ammonia slip exceeding 10 ppm.
Therefore, Green Valley Environmental Protection has achieved a leap from passive emission reduction to precise and effective treatment through its” SCR Denitrification + Intelligent Co-control “technology system. The SCR system, under the synergistic action of specific temperature and catalysts, can precisely reduce NOx in exhaust gases into harmless nitrogen and water without prior reaction with O₂, significantly enhancing denitrification efficiency. By employing patented mixing technology, it ensures thorough blending of ammonia with flue gas to meet ultra-low nitrogen oxide emission standards and minimize ammonia slip below 3ppm. Additionally, precision metering injection technology ensures stable compliance with emission standards during load variations in biogas power generation units.
In a biogas power generation project of a sewage plant in Zhejiang province, the SCR denitration technology of Green Valley Environmental Protection reduced NOx emissions to the national ultra-low emission standard, helping the sewage plant to realize energy recovery and utilization, greatly reduce environmental pollution, and significantly improve the environmental image and social benefits of the enterprise.
Green Valley Environmental Protection relies on SCR denitration system to promote the biogas generator exhaust gas treatment mode from passive emission reduction to “resource regeneration + intelligent joint control”, and reshape power with science and technology to make green innovation future.
