Description

[0001] The present invention relates to an algae bloom removal equipment and method,

The present invention relates to an apparatus and a method for removing a greenhouse which can effectively remove a greenhouse suspended in water.

In eutrophicated lakes and slow-flowing streams, floating micro-algae accumulate on the surface of water after mass proliferation and change the color of the water significantly to green is defined as the algae phenomenon, also called water bloom.

Eutrophication refers to the increase in the concentration of nitrogen and phosphorus nutrients in lakes and marshes. Increasing the nutrient limitations for microorganisms can lead to rapid growth of algae at certain times when water temperature and illumination are optimal. It causes green tide of fresh water. Increasing amounts of domestic sewage and industrial wastewater have caused most of the domestic wastewater to become malnutrition, and environmental problems are occurring every year. Such a green algae phenomenon can cause the aquatic organisms to be threatened by the decreased amount of dissolved oxygen in the water due to oxygen that is consumed by the decay of the algae. The algae phenomenon can damage the human body. For example, drinking water containing a toxin caused by cyanobacteria, a kind of microalgae, which is a major cause of algae phenomenon, may cause liver damage, vomiting and abdominal pain .

In addition, from the environmental point of view, the ecosystem is destructed due to aquatic organisms such as killing of aquatic organisms due to the algae phenomenon. For this reason, the algae phenomenon is becoming a national environmental problem. Therefore, there is a great need for a technique for preventing the occurrence of a green algae phenomenon or a technique for solving the generated algae phenomenon, but a technique for preventing or alleviating the green algae has not yet been completed.

Typical algae removal techniques include the use of coagulants that remove algae by adding coagulants such as aluminum, iron, and calcium; the administration of algae, copper sulfate, and chlorine to the algal area; coagulation and sedimentation of loess and green algae; A method of controlling the greenhouse by the light shielding effect by the light, a method of spraying the microbubbles into the water at high pressure and attaching algae and microbubbles floating in the water to flood them on the water surface to remove the algae, However, there is no technology that can be applied in actual field so far due to a large amount of energy consumption and secondary pollution.

First, the flocculated floating portion 100 includes a green water tank 110 for forming a space in which the green water tank can be accommodated, and an electrocoagulation device 110 for flooding the green tank aggregate A to the water surface, (120). A green water tank inlet port 111 may be formed in the green tank water tank 110 to allow the water containing green algae to flow therein and a purified water outlet port 112 through which the purified water after the green tide is removed may be formed . The electrocoagulation device 120 includes a power supply device 121, a positive electrode plate 122 and a negative electrode plate 123. The positive electrode plate 122 and the negative electrode plate 123 are spaced apart from each other, And the positive electrode plate 122 and the negative electrode plate 123 may be connected to a power supply device 121 provided outside the greenhouse vessel 110. [ The green plate is filled in the green tanks 110 and the positive plates 122 and the negative plates 123 are filled with the green tanks so that the positive plates 122 and the negative plates 123 are connected to each other through the power supply 121, When the power is applied, the metal ions are eluted from the metal cathode plate by the electrochemical reaction and the green algae flocculates, and the metal anode plate generates micro-sized hydrogen gas to flocculate the agglomerated green algae agglomerates to the water surface, The aggregate of green algae may be floated.

The skimmer 200 may be provided at an upper portion of the green water tank 110 and may serve to remove the green aggregate A floated on the water surface of the green water tank 110.

When ultrasonic waves are applied together with the first ultrasonic wave generator 130 while the greenhouse is flocculated and floated by using the electrocoagulation device 120, the cohesion efficiency of the greenhouse can be improved and the greenhouse can be easily floated to the surface of the water . At this time, the first ultrasonic generator 130 may be installed on the bottom wall or the side wall of the green water vessel 110, and various numbers may be arranged at various positions.

&Lt; Example 5 >

The method of removing green algae according to the present invention comprises the steps of applying power to a cathode plate (122) and a cathode plate (123) spaced apart from the greenhouse water while the greenhouse water containing water is contained in the greenhouse water vessel (110) And the green algae flocculate and float by applying ultrasonic waves to the green algae water while applying power to the cathode plate 122 and the cathode plate 123 so that the green algae agglomerates A float on the surface of the cathode plate 122, And the cathode plate 123 may be cleaned by ultrasonic waves.

That is, as described in the first embodiment, the first ultrasonic generator 130 provided in the green water vessel 110 of the flocculated floating section 100 can be used to facilitate flocculation and flooding of the greenhouse, The aggregation efficiency of the green algae can be improved by using the electric agglomeration and the ultrasonic agglutination together.

When ultrasonic waves are applied to the number of green algae, the algae agglomerates. However, if the ultrasonic waves are continuously applied for a long time, the agglomerated algae are decomposed again, and the aggregation efficiency of the green algae may be lowered. Therefore, when ultrasonic waves are applied simultaneously with the electrocoagulation, if the ultrasonic waves are applied intermittently, the coagulation efficiency of the green tank can be remarkably improved.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. It goes without saying that various modifications can be made.
