Problems solved by technology

[0003] Existing natural energy mainly includes water energy, wind energy, solar energy, tidal energy, biomass energy, etc. Among them, water resources occupy most of the earth's area and are one of the energy sources we rely on for survival. With the advancement of science and technology and With the development of society, there are more and more industrial wastewater and domestic wastewater, but the treatment of wastewater has stagnated, and scientific recycling cannot be effectively realized.

Embodiment Construction

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0016] Embodiments of the present invention include the following steps:

[0017] (1) Spray the wastewater into a mist form using a diffusion nozzle, so that the wastewater is separated into small water droplets, small oil droplets and large oil droplets suspended in the air in order from bottom to top,

[0018] (2) Use a filter screen to condense and filter out the large oil droplets in the upper layer. This step separates the large oil particles in the wastewater.

[0019] (3) Slowly pass the mixture of small wate...

Abstract

The invention discloses an oil-water separation method for wastewater treatment. The method comprises the following steps: firstly, wastewater is sprayed in a mist way through a divergent nozzle; secondly, large particle oil drops in the upper layer are coagulated and filtered through a filtering screen; thirdly, the wastewater passes through a ribbed plate for lipophilic substance; fourthly, impurities in water drops are further filtered through filtering paper. By adopting the mode, the method has the advantages of convenient management, simple process, wide range in application, obvious effect, high pertinence, higher efficiency and the like, and has a wide market prospect in terms of the popularization of the method.

Description

technical field [0001] The invention relates to the field of environmental protection technology, in particular to an oil-water separation method for wastewater treatment. Background technique [0002] Energy is the basis for the survival and development of modern society. The supply capacity of energy is closely related to the sustainable development of the national economy and is one of the foundations of national strategic security. China's current energy supply situation is grim, and the burden on environmental quality is heavy. Due to the dwindling reserves of fossil energy, large fluctuations in oil prices, concerns about energy security and global warming, the development of clean and renewable energy has become an urgent issue, and the new energy industry is showing high growth. [0003] Existing natural energy mainly includes water energy, wind energy, solar energy, tidal energy, biomass energy, etc. Among them, water resources occupy most of the earth's area and a...
