摘要
为解决生物脱硫反应器酸化问题,研制出一种具有pH缓冲能力的生物填料。填料主要由碳酸钙﹑纯丙乳液和羟丙基纤维素制得。填料在水中浸泡6个月不会分解,吸水率大于20%。考察填料pH缓冲能力,结果表明,填料能将pH=5.0水溶液调节至pH=6.5以上。选取缓冲能力较稳定的BT50填料填充于反应器,以排硫硫杆菌(Thiobacillus thio-parus)挂膜,5个循环后反应器有效体积内的最大固定化菌体数量约为5.86×108cells/mL,并且硫代硫酸钠的消耗速率基本稳定,表明该填料可用于生物挂膜。在长达50 d脱硫实验中,H2S脱除率均在95%以上,整个脱硫阶段不再加入任何pH调节剂,反应器内pH仍能维持在6.7~7.1之间。
