Embodiment Construction

[0017] The gist of the present invention is to break through the usual technical thinking of using microorganisms to degrade or "eat" oil bodies in wastewater to purify oily wastewater in the prior art, and to use the hydrophobicity of certain microbial cells to directly adsorb waste water oil bodies, thereby providing a A method for treating oily wastewater using microbial cells with a hydrophobic surface as an adsorbent. The type of microorganisms with hydrophobic surfaces used in the present invention is not particularly limited, and microbial cells such as various known or naturally occurring hydrophobic bacteria, actinomycetes, yeasts and molds can be used. Those skilled in the art can easily identify and obtain such microorganisms, and dead cells obtained after inactivation of microorganisms with hydrophobic surfaces can also be used in the present invention.

[0018] In order to enable those skilled in the art to implement the present invention more conveniently, the "m...

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, and oil 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 with an overall low cost.

Description

technical field [0001] 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 [0002] 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 wastewater can be rec...
