Description

Cutting / removing apparatus of spiny seaweed which is algae and its removal method {A water-plant removal apparatus}

The present invention relates to a method and apparatus for removing spiny blue water plants growing at the bottom of a lake when removing the spiny seaweeds inhabiting the coastal shores or forming a lake park by freshwater seawater.

Prickly seaweed is a green or light green algae, also known as Echigo, which is usually a little flat and is very diverse in size and shape and can be seen in clean river mouths. It is rich in vitamins and inorganic salts and has a unique aroma and taste.

However, the exact cause is not known recently, but the rapidly growing mutant thorn in July ~ August has become a social issue. In the July 27, 2010, “Gyeongin Ilbo”, the thorny blue on Central Park Lake in Songdo, Incheon Has grown into a group, and the Incheon Free Economic Zone Authority is in trouble. ”The article was reported as follows.

The Economic Agency recently commissioned the Incheon Development Institute to find a way to remove the visible rays. Seaweed, spiny blue, grows mainly in warm water such as the west and south coasts. Central Park Lake is an artificial waterway that draws water off the coast of Songdo, where thorn-blue spores enter through a sluice and grow in large quantities at Park Lake. Lake Central Park is only 1.5 meters deep, making it alright for algae to photosynthesize. In addition, soil and food waste near the park during the summer rainy season are being washed down by the lake, making it a nutrient for thorny greens.

As the optimal conditions for the growth of thorny blue, the lake is suffering from thorny blue. The problem is that the water taxis running on the lake are struggling with safety. The Free Economic Zone Authority explains that the appearance of green algae in lakes is not good because of the color of spiny blue. The Free Economic Zone Authority has also examined how to remove thorny greens by injecting chemicals into the lake, but it is not doing so because of the possibility of secondary pollution.

In addition, the Korean policy portal (Dum. Media) of 2009.08.07. Has an article titled, "West Sea China Tsunami Emergency".

Mokpo Maritime Police Chief (CEO Yong-hwan Kim) has recently stepped up aircraft and naval vessel surveillance activities to minimize fishermen's damage, including farms caused by thorny blue seas, which occurred in the west coast. According to the seascape, the thorny blue sea, which prospered rapidly in the Qingdao sea in China this summer (May-August), flows into the country in the current, and is distributed 6 ~ 9km in the area around Hongdo ~ Daeheuksando, Hataedo ~ Ganseo in the west coast of Jeonnam. It is also distributed in the northwestern part of Gagera and southwestern parts of Gaza. When thorny sea enters the engines of ships that use seawater as cooling water, it may cause engine failure, and it is said that it is likely to cause damage when it enters beaches, farms, and village fisheries. The Coast Guard conducts jurisdictions on local water patrols, air patrols, and police officers in case of out-of-pocket and branch personnel outings. We will also establish a cooperative system with fishers and local governments. ”It is urgent to develop visible seaweed removal technology.
