, 2005 以处理量为1800m^3／h的亚硫酸钠循环法烟气脱硫装置为实验对象，着重研究吸收液pH值、液气比L／G、吸收液成份和脱硫剂初始浓度等因素对脱硫效率的影响，并对脱硫剂再生过程和再生清液的脱硫特性进行研究。结果表明：吸收液pH值决定硫成份在溶液中的状态，从而影响脱硫效率，当pH>6时，脱硫效率高且随pH增大变化平缓；当pH 90％)；同等条件下，与NaOH和Na2CO3相比较，Na2SO3的脱硫能力稍低；吸收液Na2SO3浓度在5％～10％范围内脱硫效率大于90％；脱硫剂再生反应过程能很快完成 ...

, 2003 在硫铁矿烧渣生物脱硫的实验室试验中 ,研究矿浆浓度、Fe3+浓度及pH值对游离T f 菌浓度和脱硫率的影响。结果表明硫铁矿烧渣脱硫是T f 菌直接作用和由细菌而产生的Fe3+间接作用的联合结果。脱硫速率和菌种氧化活性受吸附在固相上和液相中细菌生长浓度、矿浆浓度、pH值和Fe3+的影响。三价铁离子的添加可影响菌种活性 ,抑制浸出 ,且易在矿物表面产生沉淀 ,降低氧化率。经生物氧化脱硫后 ,硫含量降至 0 33 ...
