Description

Technical Field

[0001] The present invention relates to the technical field of industrial wastewater treatment, in particular to an emulsion cleaning wastewater treatment system device and process. Background Art

[0002] Emulsion wastewater has a complex composition, mainly containing mineral oil or mechanical lubricant, lubricating fluid, surfactant, additive, thickener, soluble organic compound, metal powder and solid suspended solids, which makes it difficult to treat. Currently, chemical cleaning, biological decomposition and other methods are mostly used for treatment. For example, Chinese invention patent with authorization announcement number CN113480101A discloses an emulsion cleaning wastewater treatment system device, including a regulating tank, a coordinated advanced oxidation device, a dosing tank, a dosing system and a biological treatment device. The regulating tank is connected to the coordinated advanced oxidation device, the regulating tank is connected to the dosing tank, the dosing system is connected to the dosing tank, and the biological treatment device is connected to the dosing tank. However, this treatment method has the following disadvantages:

[0003] When treating emulsion wastewater, the original liquid is directly treated, while chemical cleaning, biological decomposition and other treatment methods take a long time. In this way, the emulsion wastewater original liquid needs to stay for a long time, resulting in the overall treatment equipment being bulky and occupying a large area. In addition, when performing chemical cleaning, the chemicals are directly added, so that the chemicals gather in a relatively concentrated position in the wastewater and are not easy to disperse. They can only be mixed by stirring, resulting in a slow mixing speed of the chemical liquid and the wastewater, affecting the efficiency of chemical cleaning.

[0053] Example 4:

[0054] See also Figure 1-12, which is the fourth embodiment of the present invention. This embodiment is based on the above three embodiments. When the present invention is used, the emulsion wastewater is introduced into the raw water pool 11 from the raw water inlet pipe 12, and is filtered out of large particles of impurities through the sewage screen machine 15, and then discharged into the ceramic fine filter component 2 from the raw water outlet pipe 14. Step 2: Fine filtration: The wastewater enters the sewage pool 22 in the ceramic fine filter component 2, and then enters the vertical filter tank 21 to be filtered through the tubular ceramic membrane 28 to filter out suspended matter, microorganisms and some fine particles.

In this process The concentrated wastewater generated in the process is then cleaned and treated by the chemical cleaning component 4, and after the treatment is completed, fine filtration and ultrafiltration are performed to form a cycle; when treating the emulsion wastewater stock solution, the present invention first adopts the method of fine filtration plus ultrafiltration. The fine filtration and ultrafiltration methods are faster.
