摘　　要：以红浅稠油区稠油废水为研究对象,在高温条件下(70℃以上),选用常规钙镁除硅工艺和混凝强化除硅工艺进行了除硅的试验研究。结果表明,经过两种工艺的处理,出水二氧化硅的含量均能达到回用热采锅炉的标准,但采用混凝强化工艺在技术上更为合理,经济上更为可行。The heavy oil wastewater from Hongqian oilfield was treated by a conventional technology using compounds of calcium or magnesium and enhanced coagulation to remove silicon at high temperature (above 70 ℃).The results showed that: silicon dioxide in the treated effluent from the two processes can both meet the requirement of feed water quality for thermal boilers,but enhanced coaglation process was more feasible than other processes in terms of economical efficiency analysis.
