微波辐照法处理炼油厂浮渣的实验研究

摘要

For the nature and characteristics of refinery scum,we use microwave irradiation technology to treat it.We studied some major factors which influence the dehydration rate of scum,such as microwave power,time and flocculant dosage,to determine the optimum conditions. The results showed that： microwave irradiation technology can reduce the volume of scum down to 30 % of the original volume,down 10 % from the traditional treatment,to achieve the quantity reduction treatment.Furthermore,it can save 2/3 flocculant dosage,and significantly reduce the COD value of separated water,and the process is simple,efficient and easy.%针对炼油厂浮渣的性质和特点,使用微波辐照法处理炼油厂浮渣。分别考察了微波辐照功率、时间、絮凝剂用量对浮渣脱水率的影响,确定了最佳工艺条件。实验结果表明：微波辐照处理后浮渣的体积减少到原浮渣体积的30%左右,比传统方法降低了10%,实现了浮渣的减量化处理,并且节省了2/3的絮凝剂用量,大幅降低了脱出水的COD值,而且工艺简单,高效易行。
