| 摘 要： | 稠油污水回用锅炉处理中,除硅过程对于锅炉的安全运行非常重要,而除硅剂的选择则是除硅过程重要的环节之一.本文研究了温度、反应时间、介质pH及除硅剂的加量等对稠油污水中SiO2去除率的影响,并与絮凝剂复配强化除硅效率.研究表明:当温度为60℃、反应时间为3h、介质pH为7.0及除硅剂的加量为0.75g/L时,SiO2残留量由200mg/L降低到23.2mg/L.

| Abstract: | Silicon removal is very important to the safe operation of the boilers for the treatment of dense oil polluted water.And the selection of desilication agent is one of key factors to the desilication process.The desilication agent together with flocculant is used in order to increase the removing ratio of silicon.The effects of reaction temperature,reaction time,pH value of reaction system and dose of desilication agent on the removing ratio of SiO2 in the wastewater are investigated through orthogonal tests.It is shown that the remains of SiO2 is reduced from 200 mg/L to 23.2 mg/L when the reaction temperature,reaction time,pH value of reaction system and dose of desilication agent are 60 ℃,3 h,7 and 0.75 g/L seperately. |
