Abstract

The invention provides a method for treating oily wastewater by making hydrophobic microorganism cell as absorbent, which consists of an absorbing step-the hydrophobic microorganism cell is put into and mixed with the oily wastewater to absorb oil body in the oily wastewater; and a separating step- cell-oil body complexes formed by the absorbing step is separated from the oily wastewater.The cell-oil body complexes which are easy to be separated can be formed after absorbing; after the cell-oil body complexes are separated from the wastewater, COD and BOD of the wastewater can be lowered, andoil body can be extracted from the cell-oil body complexes to be reused or the complexes can be used as ferment medium composition of other microorganism or as fuel.The method can be widely used withan overall low cost.

Description

Oily wastewater treatment method technical field The invention relates to an adsorption method for treating oily industrial wastewater and a resource recovery method, or to a microbial treatment method for wastewater. Background technique Oily industrial wastewater is a kind of industrial wastewater with a wide range of sources. It is discharged in large quantities during oil extraction, transportation and processing, extraction and processing of animal and vegetable oils, and mechanical processing and cleaning. At present, for oily industrial wastewater, oil separation, air flotation, coagulation sedimentation and biodegradation are mainly used to remove the oil body in the wastewater to reduce the COD and BOD values ​​of the wastewater and make it meet the discharge standard. However, adopting these treatment methods will not only consume a large amount of energy and chemicals, but also cannot produce any economic benefits. If the oil bodies in various states in oily wa...
