含油乳化液废水与含硫废水、高COD废水、含酚废水一样是石油化工厂重要的污染源。已乳化的含油废水如直接排入污水处理场统一处理,由于乳化剂的作用,使没有乳化的废水也乳化了,于是提高了废水的处理难度,增加了处理的费用。如何对已乳化的含油废水进行特殊处理,是人们尤为关注的问题。
Oily emulsion wastewater and sulfur-containing wastewater, high COD wastewater, phenol-containing wastewater is the same as the petrochemical plant is an important source of pollution. Emulsified oily wastewater is directly discharged into the sewage treatment plant for uniform treatment. Due to the action of the emulsifier, the emulsified wastewater is also emulsified, thereby increasing the difficulty of wastewater treatment and increasing the processing cost. How to deal with emulsified oily wastewater is a problem of particular concern to people.
