一、提要哈尔滨炼油厂含油污水处理,基本上沿用了我国石油炼制工业采用的“老三套”(即隔油、浮选、曝气)。通过生产实践,证明在高寒的黑龙江地区,采用这套露天设施,处理含油污水,基本上是可行的(见《“老三套”处理含油污水情况介绍》一文)。在此基础上,又于浮选池内增设了斜板分离器,在不增加浮选池的情况下,提高了除油效果和分离矾花的能力,使曝气进水油含量保持在30mg/L 以下。
First, the summary Harbin oil refinery oily wastewater treatment, basically followed the oil used in China’s oil refining industry, “the third set” (that grease, flotation, aeration). Through the practice of production, it is basically feasible to use this set of open air facilities to treat oily wastewater in the cold Heilongjiang region (see “The Third Pilot Project for Treatment of Oily Wastewater”). On this basis, the addition of a swash plate separator in the flotation cell, without increasing the case of flotation cells to improve the degreasing effect and the ability to separate alum so that the aerated oil content remained at 30mg / L or less.
