Problems solved by technology
Since the diverted pollutants (flocculants) do not flow through the filter 130 and are discharged directly into the water system, the algae removal efficiency will be reduced
Conversely, if the removal efficiency of algae is to be improved, the filter 130 needs to be replaced manually every once in a while
Since the formed biofilm will not only shorten the life of the filter 130, but also increase the cost due to frequent replacement of the filter 130, it is difficult to realize the practical use of the algae removal device using the flocculation-filtration method

Embodiment Construction
[0047] Embodiments of the method and device for removing algae using chlorine dioxide according to the present invention will be described in detail below with reference to the accompanying drawings.
[0048] first, figure 1 It is a schematic diagram illustrating the method and device for removing algae by using chlorine dioxide in the present invention.
[0049] As shown in the figure, the removal method of the present invention is a 'water treatment method', that is, the water body in the water system is pumped, and the algae and nutrient salts are removed by the algae removal device, and then the water is discharged into the water system. Its feature is to pass chlorine dioxide into the raw water flowing into the filter device to kill algae contained in the raw water. This method can inhibit the formation of biofilm and remove biofilm to improve the filtration efficiency, and then pass through the discharge water discharged from the filter device. Chlorine dioxide is inje...

Abstract
The invention provides a method for removing algae using chlorine dioxide and a device thereof for removing algae in natural water systems such as reservoirs, lakes, rivers and the like, and manmade water systems such as golf courses and the like, wherein the algae can sharply breed and cause the red alga and green alga phenomenon in the water systems. Particularly, the method is characterized by comprising the following steps of: sucking the water in the natural water systems and the manmade water systems, then performing a primary solid-liquid separating process to the algae contained in the raw water, supplying the discharged water after the primary solid-liquid separating process to a filter device to perform a secondary solid-liquid separating process to separate the algae remained in the discharged water, then feeding the chlorine dioxide into the discharged water through the filter device, thereby preventing generating biomembrane and removing the biomembrane in the filter device so as to improve the filter efficiency, finally, feeding the chlorine dioxide into the discharged water of the filter device to remove the residual algae discharged in the discharged water of the natural water system and manmade water system to improve the concentration of the dissolved oxygen.
Description
technical field [0001] The invention relates to a method and device for removing algae by using chlorine dioxide, which is used for removing algae in natural water systems such as reservoirs, lakes, rivers, and artificial water systems such as golf courses. The algae can multiply rapidly and easily in the above water systems Causes red and green algal phenomena. Background technique [0002] Under normal circumstances, if there is too much organic matter, nitrogen, phosphorus and other nutrient salts in natural water systems such as reservoirs, lakes, rivers and artificial water systems such as golf courses, and eutrophication occurs, the plant-based plankton that ingests the nutrients Or algae will multiply rapidly in a short period of time, thereby dyeing the entire water system red or yellow-green, thus triggering the phenomenon of red algae or green algae. [0003] The above-mentioned eutrophication phenomenon occurs when excessive amounts of nutrients necessary for the...
