The present invention relates to a sediment purification and maintenance device of the bottom of the water, and more particularly, it is possible to improve the purification efficiency by injecting a purifier while depositing on the bottom of the sea, rivers, lakes, etc., which causes eutrophication. In addition, the present invention relates to a sediment purification and maintenance device for underwater floors that can deliver contaminated sediments.

As civilization develops, when various kinds of domestic waste and industrial waste enter the nearby sea, lake, or river, a large amount of inorganic or organic matter contained in the waste water is deposited on the bottom of the water. Sedimentary pollutants do not end up as simple deposits, but they act as a nutrient source for various species, particularly algae, causing red and green algae to thrive.

In particular, the damage caused by the proliferation of such algae is particularly serious in sea bream, where fish and shellfish are mainly produced. Recently, due to the development of fisheries technology, various fish, shellfish and seaweeds have been farmed in the coastal waters. However, it is well known that industrial effluent, urban sewage, shipboard waste, etc. are heavily polluted by the coastal waters. Contaminated seawater can recover to some extent by the currents such as turbulence and the Korean wave, but oxygen deficiency occurs in the seabed mudflats where contaminants are deposited, so that sewage and pollutants are decomposed by anaerobic bacteria and protozoa. Intermediates, such as methane (CH4), ammonia (HN4), hydrogen sulfide (H2S), and low molecular weight fatty acids, are produced, and these intermediates decompose and diffuse in seawater, interfering with the growth of settled aquatic organisms and causing toxic red tide. Providing fundamental factors will destroy marine ecosystems such as disruption of fish stocks. In particular, in aquatic shellfish such as shellfish and oysters, seaweeds such as seaweed, seaweed, seaweed, and kelp, aquaculture is not possible because of the impossibility of aquaculture. Measures for improvement are required. Clay is a basic component of mineral origin, such as sand of fine particles by coastal erosion, lime of dead algae and siliceous skeleton, and when the contaminants and solid precipitates are accumulated, Inhibiting the growth of the food chain will cause a loss of the fact that eventually, the red tide phenomena caused by eutrophication of seawater is generated, causing ecosystem destruction.

As a proper countermeasure when the above-mentioned red tide occurs, cases of red tide have been eliminated by spraying clay on seawater and alkalizing acidified canopy. It has also been reported that some productivity has been improved by self-healing.

However, in the clay spreading method, the spreading efficiency of the clay spreads in a wide range due to the current, and the eutrophication material on the bottom of the water remains as it is, and the red tide phenomenon is repeated every year. In addition, since ports and portholes are reduced to the dead sea due to the accumulation of various industrial and household wastes, there is a need for regular use of vacuum cleaners to purify and clean sediments from underwater floors such as the sea and rivers.

In order to solve the above problems, as shown in FIG. 7, Korean Laid-Open Patent Publication No. 2001-0106587 installs a bottom plate 51 at a lower portion of the frame 52 having a mesh 57 at the rear and a frame ( 52 is provided with a weight portion 56 on both sides of the recovery frame (5) which is pulled in contact with the sea bottom opening by the wire (4) connected to the hull, and fixed to the connecting table 58 on both sides in front of the recovery frame (5) The subsea sediment maintenance device which consists of the injection mechanism 6 which installs and sprays the seawater which the purifier supplied from the pump through the connection hose 7 was mixed to the back side and the back side through the nozzles 64 and 65 is disclosed.

However, the conventional subsea sediment maintenance apparatus shown in FIG. 7 has a disadvantage in that the purifying agent mixed in the injected seawater is not mixed well with the dog pearl and the purification efficiency is lowered.

The present invention has been made in order to solve the above problems is an object of the present invention by spraying a purifier to the sediment of the bottom of the water and at the same time the sediment of the bottom of the water by tilling the sediment so that the injected purifier is mixed well with the sediment of the bottom of the water. It is to provide a sediment purification and maintenance device of the bottom of the water to improve the efficiency of the purification.
