Embodiment

[0043] Example: see Figure 1 to Figure 2 , the present embodiment provides a method for mechanical demulsification, oil removal and dust removal of waste water, which comprises the following steps:

[0044] (1) Mechanical demulsification:

[0045] (1.1) A mechanical demulsification device is provided, which includes a tank body 1, a mechanical demulsification mechanism 2 is provided in the tank body 1, a mechanical demulsification water inlet valve 3 is provided on the top of the tank body 1, and a mechanical demulsification water inlet valve 3 is provided on the side of the tank body 1 There is a mechanical demulsification outlet valve 4;

[0046] (1.2) The waste water enters the tank body 1 through the mechanical demulsification inlet valve 3, and the mechanical demulsification mechanism 2 generates mechanical vibrations to condense the water particles. At the same time, the mechanical demulsification mechanism emits ultrasonic waves. When the ultrasonic waves pass through t...

Abstract

The invention discloses a method for carrying out oil and dust removal on wastewater by mechanical demulsification. The method is characterized in that the method comprises the following steps: firstly, mechanical demulsification; secondly, oil-water separation; thirdly, dust removal. The invention further discloses a system for carrying out the oil and dust removal on the wastewater by the mechanical demulsification implementing the method. The dosage of a demulsifier can be greatly reduced by the mechanical demulsification adopted by the invention; after oil-containing wastewater is mechanically treated by ultrasonic waves, the fluidity is greatly increased; in addition, after crude oil is stood for a long time, the viscosity of the crude oil does not recover; after ultrasonic mechanical treatment, the standing and staying time of the crude oil can be greatly shortened. By adopting the mechanical demulsification, the production cost can be effectively reduced, and economic benefits are increased.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a waste water mechanical demulsification, oil and dust removal method, and a system for implementing the method. Background technique [0002] my country's energy structure is "rich in coal, poor in oil, and low in gas". Coal is the safest, most economical, and most reliable energy source in China. Its reserves far exceed oil and natural gas resources. However, with economic development and environmental protection requirements, clean The sustainable supply of energy has become an important condition for national economic development. Combined with this situation, in recent years, the domestic coal chemical industry has developed rapidly, but the wastewater discharged by coal chemical enterprises is recognized as one of the difficult-to-treat wastewater, and the wastewater produced is a wastewater containing a large amount of toxic and harmful substances. It is a typical industria...
