Description

Algae removal system under coupling action of electric field and ultrasonic field

Technical Field

The utility model relates to a water purification's except that algae technical field especially relates to a remove algae system under electric field and ultrasonic field coupling effect.

Background

Along with social development, people discharge a large amount of N, P pollutants into water bodies in industry, agriculture and daily life, so that water eutrophication is aggravated. At present, the problem of water eutrophication has become a global environmental problem, especially for developing countries. At present, lakes in China are almost all in eutrophication or heavy eutrophication state, so that algae are propagated in large quantity to form water bloom and seriously pollute water quality.

Blue algae, green algae and diatoms are the three most important algae in natural lakes, wherein the harm of the blue algae is the most serious. The water bloom frequently occurs in eutrophic water, the water bloom can cause peculiar smell of the water, block a water supply system and influence landscape, and the toxin generated by the blue algae can threaten the safety of aquatic ecology, livestock and even human beings.

The cyanobacterial bloom is a phenomenon that cyanobacterial in a surface water body rapidly grows to become dominant species under the conditions of proper temperature, illumination and nutrient salts. The phenomenon that blue algae with buoyancy or movement ability gathers and forms scum on water surface is called surface water bloom, and the phenomenon is usually called surface water bloom. The blue algae forming the surface water bloom is a species with pseudo vacuole and high biomass, and typical algae species are microcystis aeruginosa, anabaena, synnema and the like.

There are two main aspects to which algae control and removal techniques can be attributed: the method aims at algae inhibition of water bodies, and comprises biological control, a water changing method, a chemical method and a sediment dredging method; and secondly, the removal rate of the algae is improved by adopting a certain water purification process in a water plant, wherein the process comprises a chemical agent method, air flotation, direct filtration, a biological treatment method and the like. With the continuous development of ultrasonic technology and sonochemistry, people pay more and more attention to the application of ultrasonic waves in algae removal and inhibition. The ultrasonic algae removal method mainly utilizes an ultrasonic technology to destroy physiological and biochemical activities of blue algae cells so as to kill the blue algae, but the ultrasonic algae removal method has certain defects: some algae can form a sublethal state, namely, the algae are only damaged by cells and are not really killed, and after a period of time, the algae can regenerate in the water body to continuously pollute the water body.

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings:

as shown in fig. 1, an embodiment of the present invention provides an algae removal system under the coupling effect of an electric field and an ultrasonic field, including:

the floating cushion bodies 1 are used for floating on the water surface, and the two floating cushion bodies 1 are arranged in parallel at intervals left and right;

the bearing base plate 2 is horizontally arranged between the two buoyancy cushion bodies 1;

and the ultrasonic generator 5 is connected with the ultrasonic transducer and is used for converting the electric signal generated by the ultrasonic transducer into mechanical vibration of the ultrasonic transducer.

The ultrasonic generator is connected with a power supply, the ultrasonic generator is a power generator in essence, and generates a sine signal with a certain frequency, and the sine signal is transmitted to the ultrasonic transducer through a cable connecting wire, and the ultrasonic transducer converts an electric signal provided by the ultrasonic generator into mechanical vibration. The mechanical vibration is utilized to act on the impact wave generated by the cavitation effect generated by the water body to break the cell wall of the algae, break the air cells and destroy active enzymes, so that most of the blue algae are inactivated and die, and a small part of the blue algae can be damaged by the cells and enter a sub-lethal state. The special structure of the algae cell is an air cell which accounts for 50 percent of the cell volume, the air cell controls the lifting motion of the algae cell, and the air cell of the algae cell can be broken by strong shock waves, jet flows, radiation pressure and the like generated at the moment of collapse of ultrasonic cavitation bubbles, so that the cell wall is broken, and active enzyme is damaged. Meanwhile, the high temperature and high pressure and a large amount of free radicals generated by the cavitation bubbles can destroy active enzymes and active substances in algae cells, thereby influencing the physiological and biochemical activities of the cells. Moreover, the chemical effect caused by the ultrasonic wave can also decompose algal cell secretion and metabolite such as algal toxin and the like, promote the aggregation and sedimentation of algal cells, and in addition, no chemical agent is used in the treatment, no water source is polluted, no secondary pollution is generated, and the method is non-toxic, harmless, safe and reliable.

In addition, in order to further thoroughly eliminate a small part of algae entering a sublethal state, the system also induces the sublethal algae formed after ultrasonic treatment by combining a coupling electric field technology and utilizing a certain electric field generated by an electrode plate, and utilizes a pressure difference principle to enable cell sap in the cell sap to flow out of a cell body through perforation caused by ultrasonic waves so as to cause complete death of the cell body, thereby further improving the algae removal efficiency.

In one embodiment of the present invention, the buoyancy spacer is a flexible bag with a filling chamber therein, and the filling chamber is filled with gas. The buoyancy cushion body is convenient to be placed on the water surface.

In another embodiment of the present invention, the buoyancy spacer is a boat-shaped structure made of low-density resin or polyethylene. The buoyancy cushion body is in a ship shape in appearance design so as to be capable of floating freely and placed stably in water, the stability of the buoyancy cushion body is improved, and the ultrasonic transducer on the bearing substrate can work conveniently.

Further, a plurality of electrode plates 3 are equidistantly arranged on the upper end surface of the bearing substrate 2. So that the electric field directly acts on the algae floating on the water surface and in a sub-lethal state, and the algae can be inactivated and killed completely and better.

In order to carry out insulation and waterproof treatment on the electrode plate, the electrode plate is subjected to waterproof treatment by adopting epoxy resin pouring sealant. The epoxy resin is saturated resin, and the epoxy resin pouring sealant produced by taking the epoxy resin as a base material has the characteristics of high body strength, strong bonding force, good weather resistance, high insulating strength, no toxicity, environmental friendliness and the like, can protect the electrode plate in all directions, and greatly prolongs the service life of the electrode plate.

It should be noted that the ultrasonic frequency of the ultrasonic generator is controlled between 1KHz and 10 MHz. The ultrasonic wave with the frequency has low energy, the ultrasonic wave with the low energy has stronger treatment capability on blue-green algae with the strongest harm in the water body, has better treatment and inhibition effects on green algae, has better inhibition effects on diatom, and cannot cause obvious influence on the survival of fishes in the water body.

Obviously, the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention, and it is obvious for those skilled in the art to make other variations or changes based on the above descriptions, and all the embodiments cannot be exhausted here, and all the obvious variations or changes that belong to the technical solutions of the present invention are still in the protection scope of the present invention.
