Gongye shui chuli, 2011 以海藻酸钙胶囊固定活性炭和血红蛋白,研究了H2O2存在下其对水溶液中五氯酚的吸附催化去除作用。讨论H 2O2及五氯酚的初始浓度、血红蛋白固定量以及pH等对五氯酚去除率的影响。结果表明,当溶液的pH为7 H2O2浓度为8.5×10-4 mol/L、血红蛋白固定量为6.6×10-6 mol/L、反应温度为25℃,反应时间为280 min时,五氯酚去除率可达到81.8%,且固定化血红蛋白可被反复使用多次。

Gongye shui chuli, 2010 IMO-SBR工艺是结合了固定化微生物技术与SBR工艺的一种全新污水处理工艺。该工艺充分利用了固定化微生物和SBR的优点,既保留了固定化微生物,又较好地利用了成熟的SBR工艺。在实验反应器内装填由聚氨酯泡沫制成的生物膜载体,并以实际高浓度氨氮废水为研究对象,通过考察温度、进水m(C)∶m(N)、pH对IMO-SBR工艺脱氮效果的影响,确定最佳的运行条件为:温度在30℃、m(C)∶m(N)=3∶1、pH=8,该工艺条件下,氨氮去除率稳定在55%以上。
