摘要:
目的 超滤技术处理含油废水在工程中得到广泛应用，为了研究基于亲水透析膜的高乳化油污水分离特性， 方法 利用1000号矿油型汽缸油(GB/T 447-1994) 及乳化剂等制备高乳化油污水，搭建小型高乳化油污水分离试验装置，利用流量计、油份检测仪等仪器设备测量不同孔径透析膜组件处理不同温度、不同浓度高乳化油污水原液的效能，并按MEPC.107(49) 决议研究膜组件的抗污性能，以及膜组件频繁自清洗后处理效能的衰减特性。 结果 试验发现0.1~0.45 μm孔径透析膜随着孔径的增加，其处理能力随之增加；且3种膜具有相似的温度-流量特性，即随着温度的增加处理能力先增后减，其中0.45 μm的透析膜在处理55~60℃原液时效能最佳。 结论 研究中形成的各类特性数据对于高乳化油污分离装置的设计、使用操作具有工程指导意义。 Abstract: Ultrafiltration technology is widely applied in the treatment of ship's oily wastewater. In order to study the disposal testing characteristics of highly emulsified oily wastewater based on hydrophilic dialysis membranes, No.1000 cylinder oil and emulsifier is used to make highly emulsified oily wastewater, and a small oil/waster separating tester is created. The relationships between the temperature, consistency of original highly emulsified oily wastewater and dialysis membrane aperture are tested. Not only is the pollution resistance of the dialysis membrane tested on the basis of resolution MEPC.107(49), but the attenuation characteristic of the dialysis membrane is also tested after self-cleaning each time. All the tests show that for dialysis membranes with in the range 0.1 μm to 0.45 μm, the treatment capability will increase with the aperture; they all show a similar flow vs temperature curve, with the treatment capability first increasing and then decreasing with the increasing temperature; when the aperture of the dialysis membrane reaches 0.45 μm, the separation of highly emulsified oily wastewater is best achieved at 55-60℃. All the data and characteristics of this research will be helpful in the design and operation of highly emulsified oily wastewater disposal equipment.-
