Embodiment

[0050] Example: see figure 1 , the present embodiment provides a method for dedusting and degreasing waste water, which comprises the following steps:

[0051] (1) Dust removal:

[0052] (1.1) Prepare a dust removal mechanical filter, which includes a cylinder shell 1, a water passage 2, a grid 3, a dust removal filter material 4 and a central water distributor 5, and the dust removal filter material 4 is arranged in the grid 3, and the The water channel 2 is set between the grid 3 and the inner wall of the cylinder shell 1, and the central water distributor 5 is set in the middle of the inside of the cylinder shell 1;

[0053] (1.2) Set a dust removal water inlet valve 6 at the lower part of one side of the cylinder shell 1, set a dust removal water outlet valve 7 at the upper end of the cylinder shell 1, and set a dust discharge valve 8 at the upper end of the cylinder shell 1;

[0054] (1.3) The waste water enters the water passage 2 through the dust removal water inlet val...

Abstract

The invention discloses a method for removing dust and oil from coal-chemical engineering wastewater. The method comprises following steps: (1), dust removing: wastewater enters a water channel through a dust removing water inlet valve and rotates for 360 degrees in the water channel to flow upwards, pressure difference is formed, the wastewater enters a center water distributor through a grid and a dust removing filter material under the action of the pressure difference and then flows out from a dust removing water outlet valve, suspended solids are intercepted by the dust removing filter material, and the dust removing of the wastewater is completed; (2), oil removing: the wastewater after dust removing enters a tank through an oil removing water inlet valve and moves downwards under the action of gravity, lipophilic groups of the filter material absorb dispersed oil drops in the wastewater when the wastewater passes an oil removing particle membrane, oil is enabled to be demulsified on the oil removing particle membrane, a thin film is formed, water after oil removing continuously flows downwards and is discharged from an oil removing water outlet valve, oil molecules are intercepted and accumulated to form oil drops, the enriched oil drops are separated in a large oil drop form and float upwards to the top end of the tank, and oil removing is completed. The invention further discloses a dust and oil removing system implementing the method.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a method for dedusting and degreasing waste water and a system for dedusting and degreasing 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 industrial wastewa...
