悬浮污泥过滤技术在炼油污水处理中试验研究

Experimental research on suspended sludge filtering technology in refinery wastewater treatment

悬浮污泥过滤技术又称SSF污水净化处理技术,其污水净化工艺包括物化工艺和SSF污水净化器二部分,是一套纯物理化学法污水处理装置系统。文中将该技术用于炼油污水处理试验,试验表明:SSF工艺除油效果明显,污油去除率达到75.6%,COD去除率约42%,出水水质稳定良好,达到进入生化单元水质的要求,可以替代常规水处理中的浮选单元。SSF悬浮污泥过滤技术为传统的炼油污水处理工艺提出了一条新的技术路径。

Suspended sludge filtration technology is otherwise called SSF wastewater treatment technology.Its wastewater purification technics contains reification technics and SSF wastewater purifier.It is a pure physical-chemical wastewater treatment plant system.This technology was used in refinery wastewater treatment experiment.The experiment shows that SSF technique has obvious degreasing effect,waste oil removal rate is up to 75.6%,COD removal rate is about 42%,effluent water quality is stable and fine and meets the requirements of flowing into biochemical unit.So it can replace the flotation cell of routine wastewater treatment.SSF technology proposes a new path for traditional refinery wastewater treatment technique.
