摘要
研究了磁分离法处理含动植物油废水的原理和工艺条件结果表明，当废水含油量为１１２～１８５５ｍｇ／Ｌ、ＣＯＤＣｒ为２８００～８０２０ｍｇ／Ｌ时，用磁分离法处理，可使油和ＣＯＤＣｒ去除率分别达到８５％和７５％以上磁分离的磁种（粉）需用量为２５０ｍｇ／Ｌ。
The technological conditions and principle of treating the animal and vegetable oils-bearing wastewater by the magnetic separation method were studied. Experimental results show that oils and CODCr removal rates for magnetic separation treatment of the wastewater containing 112～1855mg/L oils and 2800～8020 mg/L CODcr werw over 85% and 75% respectively under the conditions recommended. The does of magnetic seed (particle) is 250 mg/L, and they can be utilized repeatedly. The magnetic-particles used for the tests in this paper were prepared by this research group.
