Study on the application of polyaspartic acid complex iron system on biogas desulfurization in wastewater treatment plant
The advantages and disadvantages of several gas desulfurization technologies are introduced and compared.Using biogas from a wastewater treatment plant as the research object,the polyaspartic acid,ethylenediaminetetraacetic acid,aminotriacetic acid,and diethylenetriaminepentaacetic acid are used as complex agents.The desulfurization effect,regeneration effect and corrosion resistance effect are investigated.The experimental results show that the desulfurization effect of polyaspartic acid complex iron is superior to other complex agents,with a desulfurization rate of over 99.9％.The complex agent is environmentally friendly and easy to degrade,which can meet the requirements of biogas desulfurization.It can also keep the desulfurization equipment pipeline in a long-term stable state,ensuring the continuous and stable desulfurization process.
