Problems solved by technology

The traditional treatment of wastewater often does not do special treatment for the emulsion in the wastewater, and only adopts conventional methods such as flocculation and biochemistry for treatment. The cost of wastewater purification is relatively high, and the purification efficiency and effect also have a lot of room for improvement.

Embodiment Construction

[0037] The present invention will now be further described in detail in conjunction with the drawings and embodiments. These drawings are all simplified schematic diagrams, and only illustrate the basic flow of the present invention in a schematic manner, so it only shows the structures related to the present invention.

[0038] like figure 1 Shown, a kind of purification method that contains emulsion wastewater, comprises the following steps:

[0039] (1) The wastewater containing the emulsion is stored in the wastewater storage tank 1 . Wastewater contains a large amount of emulsion and other organic, inorganic and oily substances.

[0040] (2) Due to the high degree of dispersion of the emulsion, strong stability, and high difficulty in treatment, in order to improve the efficiency of wastewater purification and save costs. Firstly, pretreatment is carried out for the emulsion in the wastewater. The waste water flows into the demulsification tank 21, and the demulsifier ...

Abstract

The invention relates to a method for purifying wastewater containing emulsion. The method is characterized by comprising six steps of demulsification air flotation, ultraviolet catalytic oxidation, pretreatment flocculation air flotation, facultative membrane biological reaction, post-treatment flocculation air flotation and Fenton oxidation reaction. By combination of the steps, the method has the advantages of good treatment effect and high treatment efficiency for the wastewater containing emulsion, high purification degree of treated wastewater and the like. Compared with conventional design, the emulsion which is high in treatment difficulty and stably dispersed is subjected to demulsification air flotation and ultraviolet catalytic oxidation treatment. Thus, biodegradability of theemulsion is improved, wastewater purification efficiency is improved, unnecessary waste caused by excessive input of treatment agents is also prevented, and the cost is saved. Meanwhile, Fenton oxidation reaction is placed at the end of the whole treatment process, and the running cost of wastewater treatment is reduced. The treatment method has high impact load resistance and is simple to operate.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a method for purifying wastewater containing emulsion. Background technique [0002] In current industrial production, a lot of emulsions, such as emulsified oil, high-efficiency detergent, etc., are introduced for lubrication, cleaning or other purposes. This type of emulsion has the characteristics of high dispersion and good stability, so it is very difficult to treat. The traditional treatment of wastewater often does not do special treatment for the emulsion in the wastewater, but only adopts conventional methods such as flocculation and biochemistry for treatment. The cost of wastewater purification is relatively high, and there is a lot of room for improvement in purification efficiency and effect. Therefore, it is the problem to be solved by the present invention to provide a method for purifying wastewater containing emulsion with good wastewater purification effect,...
