Problems solved by technology

The most serious problem is water pollution. In order to reduce the cost of treatment, a large amount of solid domestic waste is directly dumped into rivers, lakes and seas, forming serious solid pollution.
At the same time, serious oil spills often occur during oil extraction and transportation, and the floating oil has caused irreversible damage to the ecosystem. For example, the oil spill in the Gulf of Mexico in the United States caused a large number of bird deaths and polluted the long coastline. The damage will take decades to repair

Embodiment 1

[0030] A device that uses surface tension to clean water surface pollutants, such as figure 1 As shown, it includes an active agent release plate 1 and a pollutant interception plate 2 arranged symmetrically along the length direction. The inside of the active agent release plate 1 is equipped with a biosurfactant 11, and the inside of the active agent release plate 1 is provided with several for The release micropore 12 for releasing the biosurfactant 11 and the first barometer 13 for sensing pressure; the inside of the pollutant intercepting plate 2 is equipped with oil 21, and the inside of the pollutant intercepting plate 2 is provided with a number of holes for adsorbing pollutants. Adsorption micropores 22, a second pressure gauge 23 for sensing pressure, and a solid pollutant fishing net 24 for fishing out solid pollutants.

[0031] In this specific example, as figure 1 As shown, the active agent release plate 1 communicates with the pollutant intercepting plate 2 thro...

Embodiment 2

[0039] With above-mentioned embodiment 1, as image 3 As shown, the difference is that the active agent releasing plate 1 and the pollutant intercepting plate 2 are independent of each other, the active agent releasing plate 1 is provided with a suction pump 7 , and the pollutant intercepting plate 2 is provided with an exhaust pump 4 .

[0040] The corresponding step (1) in the process of cleaning pollutants is as follows: turn on the air suction pump 7, close the exhaust pump 4, pump air into the active agent release plate 1 until the first air pressure gauge 13 shows that the pressure reaches 1.1 atmospheres, then turn on the air suction pump 7. The air pump 7 is closed, the exhaust pump 4 is opened, and the air in the pollutant intercepting plate 2 is drawn out until the second air gauge 23 shows that the exhaust pump 4 reaches 0.9 atmospheric pressure.

Abstract

The invention discloses a device for cleaning water pollutants by using surface tension and application thereof. The device is characterized by comprising an activating agent release plate and a pollutant intercepting plate, which are symmetrically arranged in a length direction; a biological surface activating agent is filled in the activating agent release plate; a release microhole and a firstair pressure gauge are arranged on the inner side of the activating agent release plate; oil is filled in the pollutant intercepting plate; and an absorbing microhole, a second air pressure gauge anda solid pollutant salvaging net are arranged on the inner side of the pollutant intercepting plate. A sewage cleaning method comprises the following steps: the biological surface activating agent is dispersed on water to generate surface tension gradients to drive pollutants on the surface to move to a collecting area; under a synergistic effect of absorption by a bent liquid surface, the pollutants are centralized on an intercepting and collecting device, and liquid pollutants and solid pollutants are classified for collection to achieve the effect of removing the water pollutants; and the device has the advantages of high cleaning efficiency, simple structure, low energy consumption, solid-liquid separation of the pollutants in place, convenience to manufacture, portability and reliability.

Description

technical field [0001] The invention relates to the field of environmental treatment, in particular to a device for cleaning water surface pollutants by using surface tension and its application. Background technique [0002] With the rapid development of modern industry in society, people's exploitation of natural resources is increasing year by year, and with it, people are increasingly destroying the natural environment. One of the most serious problems is water pollution. In order to reduce the cost of treatment, a large amount of solid domestic waste is directly dumped into rivers, lakes and seas, forming serious solid pollution. At the same time, serious oil spills often occur during oil extraction and transportation, and the floating oil has caused irreversible damage to the ecosystem. For example, the oil spill in the Gulf of Mexico in the United States caused a large number of bird deaths and polluted the long coastline. The damage took decades to repair. For this...
