Description

Technical Field

[0001] The utility model belongs to the technical field of water treatment, in particular to a water treatment ship. Background Art

[0002] Eutrophication of lakes and rivers refers to the phenomenon of water pollution caused by excessive content of plant nutrients such as nitrogen and phosphorus. When excessive nutrients enter slow-flowing water bodies such as lakes, reservoirs, estuaries, and bays, aquatic organisms, especially algae, will multiply in large numbers, causing a sharp drop in the dissolved oxygen content in the water, thus affecting the survival of fish and other organisms. Under natural conditions, the evolution of lakes from oligotrophic lakes → nutrient lakes → swamps → land is extremely slow; human activities will greatly accelerate the eutrophication of water bodies after a large amount of industrial wastewater and domestic sewage and plant nutrients in farmland runoff are discharged into lakes and other water bodies. After eutrophication, the water body often appears blue, red, brown, milky white, etc. due to the large-scale reproduction of plankton. This phenomenon is called algal bloom in rivers, lakes, and red tide in the sea. Eutrophication will affect the water quality of the water body, reduce the transparency of the water, make it difficult for sunlight to penetrate the water layer, thereby affecting the photosynthesis of plants in the water, and may cause an oversaturation of dissolved oxygen. The oversaturation of dissolved oxygen and the lack of dissolved oxygen in the water are harmful to aquatic animals and cause the death of a large number of fish. At the same time, due to eutrophication of the water body, a large number of algae with blue algae and green algae as the dominant species grow on the surface of the water body, forming a layer of "green scum", which causes the harmful gases produced by the decomposition of organic matter accumulated at the bottom under anaerobic conditions and the biological toxins produced by some plankton to harm fish. Because nitrates and nitrites are contained in eutrophic water, people and livestock will be poisoned and sick if they drink water with these substances exceeding a certain standard for a long time. After the formation of "green scum", the underwater algae will breathe oxygen in the water because they cannot get sunlight and cannot photosynthesize. The oxygen in the water will gradually decrease, and the organisms in the water will die due to lack of oxygen. The dead algae and organisms will be oxidized in the water, and the water body will become very smelly, and the water resources will be polluted and can no longer be used. Eutrophication standards for water bodies: 1) Nitrogen content in water bodies is greater than 0.2-0.3 mg / L, phosphorus content is greater than 0.01 mg / L, 2) Biochemical oxygen demand is greater than 10 mg / L, 3) The total amount of bacteria in fresh water reaches 104 / ml, 4) The concentration of chlorophyll a, which indicates algae growth, is greater than 10μg / L. Several ways to solve eutrophication of water bodies: 1) Completely eliminate the discharge of large amounts of industrial wastewater and domestic sewage from human activities and plant nutrients in farmland runoff into lakes, rivers and other water bodies. 2) Absorb and purify nitrogen, phosphorus, and other planktonic protozoa in water. 3) Algae absorb nitrogen and phosphorus substances, and other animals ingest and absorb algae, plankton, etc. as feed. 4) Chemical substances or biological bacteria eliminate. Among the above methods, the first one is that the government has issued relevant regulations, which has obvious effects, but it is a very long process to eliminate eutrophic water bodies and reverse water quality through natural degradation. The second method is effective for small water bodies, but it is difficult to implement for large water bodies because of high capital investment and technical requirements. The third method can be implemented as long as there are suitable aquatic species, and it will not cause secondary pollution, with low cost and good effect.The fourth method will produce secondary pollution and the technology is difficult to master.

[0003] Algae absorb nitrogen and phosphorus, and other animals ingest algae and plankton as feed. The main problem with this water treatment solution is that animals ingesting algae and plankton are difficult to control, which often leads to the destruction of the balance of the food chain and the death of organisms.

The utility model adopts shellfish as aquatic species for water quality treatment. For freshwater lakes and rivers, adult freshwater bivalves are used to filter eutrophic waters using their habits and ability to filter 60 to 80 L of water in 24 hours. The water quality after filtration is higher than the Class 2 water standard. Algae, plankton, and suspended matter with a diameter of less than 30 μm in the water are all food for bivalves. Eating algae can effectively reduce nitrogen and phosphorus substances; eating plankton and suspended matter with a diameter of less than 30 μm can effectively reduce the turbidity of the water.
