对西北某炼油厂废水处理系统的“三泥”样品，采用酸化氧化及调理的污泥脱水工艺进行优化研究，获得了良好的污泥脱水效果，为污泥减量化技术改造提供依据．结果表明，当反应pH＝4、H2 O2投加量为2．0 g／L、m（H2 O2）∶ m（Fe2＋）＝4∶1、反应温度为35℃、反应时间为60 min、CaO投加量为7．0 g／L、离心转速为3000 r／min ，离心时间5 min时，得到的泥饼含水率为70％～73％、石油类含量＜2％；同时，测得调理后污泥比阻（SRF）在0．3×108 s2／g左右．在一定范围内，“三泥”离心上清液中的SS、COD、石油类含量，以及浊度等，随着H2 O2投加量的增加而降低．

In this paper ,using oil refining sludge of wastewater treatment system from a refin-ery in the northwest as the sample ,the sludge dehydration process of acidification oxidation and thermal refining is put forward .It obtains good effect of sludge dewatering and provides the basis for reform of sludge reduction technology .The results show that moisture and oil content of the mud cake are respectively 70% ~73% and under 2% ,w hen pH is to 4 ,reac-tion temperature is 35 ℃ , the dosing quantity of H2 O2 is 2 .0 g/L ,the best value of m (H2 O2 )∶m(Fe2+ ) is 4∶1 ,reaction time is 60 min ,the dosing quantity of CaO is 7 .0 g/L , centrifugal speed is 3 000 r/min and centrifugal time is 5 min .After centrifugation ,at the same time ,specific resistance to filtration (SRF )is around 0 .3 × 108 s2/g .Within a certain range ,the content of SS ,COD ,oil and turbidity are decreased with the increase of the dosing quantity of H2 O2 .
