关于湿法脱硫系统取消GGH的研究

烟气脱硫是我国电力环境保护的硬性要求,源于德国技术的脱硫系统设计,我国的脱硫装置大多都安装了烟气换热器(GGH),实践表明:GGH运行起来问题很多,堵塞、腐蚀、易卡涩、费用高、占地面积大等弊端是GGH无法避免的.发达国家的烟气脱硫正在向取消GGH的方向发展,在此阐述了产生这些问题的机理,并根据我国国情,权衡利弊,论证了在我国烟气脱硫系统中取消GGH的科学可行性.     

Enhanced removal of high-As(Ⅲ) from Cl(-Ⅰ)-diluted SO4(-Ⅱ)-rich wastewater at pH 2.3 via mixed tooeleite and(Cl(-Ⅰ)-free) ferric arsenite hydroxychloride formation

An advanced cost-saving method of removal of high-As(Ⅲ) from SO₄(-Ⅱ)-rich metallurgi cal wastewater has been developed by diluting the SO₄(-Ⅱ) content with As(Ⅲ)-Cl(-Ⅰ)-rich metallurgical wastewater and then by the direct precipitation of As(Ⅲ) with Fe(Ⅲ) at pH2.3.As(Ⅲ) removal at various SO₄(-Ⅱ)/Cl(-Ⅰ) molar ratios and temperatures was investigated The results showed that 65.2–98.2%of As(III) immobilization into solids occurred at the SO₄(Ⅱ)/Cl(-Ⅰ) mo...

Robust magnetic laccase-mimicking nanozyme for oxidizing o-phenylenediamine and removing phenolic pollutants

In this study, we report a novel magnetic biomimetic nanozyme(Fe_3O_4@Cu/GMP(guanosine5′-monophosphate)) with high laccase-like activity, which could oxidize toxic ophenylenediamine(OPD) and remove phenolic compounds.The magnetic laccase-like nanozyme was readily obtained via complexed Cu~(2+)and GMP that grew on the surface of magnetic Fe_3O_4 nanoparticles.The prepared Fe_3O_4@Cu/GMP catalyst could be magnetically recycled for at least five cycles while still retaining above 70% activity.As a laccase mimic,Fe_3O_4@Cu/GMP had more activity and robust stability than natural laccase for the oxidization of OPD.Fe_3O_4@Cu/GMP retained about 90% residual activity at 90℃ and showed little change at pH 3–9, and the nanozyme kept its excellent activity after long-term storage.Meanwhile, Fe_3O_4@Cu/GMP had better activity for removing phenolic compounds, and the removal of naphthol was more than 95%.Consequently, the proposed Fe_3O_4@Cu/GMP nanozyme shows potential for use as a robust catalyst for applications in environmental remediation.
