Description

System for strengthening water eutrophication treatment

Technical Field

The utility model relates to a sewage treatment field especially relates to a system for intensive treatment water eutrophication.

Background

The water eutrophication refers to the phenomenon of water quality pollution caused by excessive content of nutrient salts such as N, P in the water. The essence of the method is that the species distribution of the water ecosystem is unbalanced and a single species grows excessively due to the unbalanced input and output of nutritive salt, so that the flow of substances and energy of the system is damaged, and the whole water ecosystem gradually goes to death.

In surface fresh water systems, phosphate is often the limiting factor for plant growth, while in seawater systems it is often ammonia nitrogen and nitrate that limits plant growth and overall production. Eutrophic substances, often nutrients of limited content in these water systems, for example, in normal freshwater systems the phosphorus content is usually limited, so that an increase in phosphate leads to overgrowth of the plants, whereas in seawater systems phosphorus is absent, while the nitrogen content is limited, so that the addition of nitrogen-containing pollutants eliminates this limiting factor and overgrowth of the plants occurs. Domestic sewage, wastewater from industries such as chemical fertilizers and foods, and farmland drainage contain a large amount of nitrogen, phosphorus and other inorganic salts. After the natural water body receives the wastewater, the nutrient substances in the water are increased, the autotrophic organisms are promoted to grow vigorously, particularly, the individual number of blue algae and red algae is increased rapidly, and other kinds of algae are reduced gradually. Algae in the water body mainly comprises diatom and green algae, the appearance of a large amount of blue algae is a sign of eutrophication, and the algae finally becomes mainly comprising the blue algae along with the development of the eutrophication. The algae can be rapidly propagated and the growth period is short. Algae and other plankton are decomposed by aerobic microorganisms after death, and dissolved oxygen in water is continuously consumed, or the algae and other plankton are decomposed by anaerobic microorganisms, and gases such as hydrogen sulfide are continuously generated, so that the water quality is deteriorated from two aspects, and a large amount of fishes and other aquatic organisms are killed. During the decay process of algae and other plankton residues, a large amount of nutrients such as nitrogen, phosphorus and the like are released into water for the utilization of new generation of algae and other organisms. Therefore, the eutrophic water body is difficult to self-purify and restore to a normal state even if the source of external nutrient substances is cut off.

In some slow-flow rivers, the water flow is slow, so that the oxygen in the water body is insufficient, and the ecological environment of the river water is further deteriorated.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1, the utility model discloses a system for strengthening water eutrophication, which comprises a kinetic energy water pumping device, wherein the kinetic energy water pumping device is connected with a water oxygenation device, the kinetic energy water pumping device comprises a pump body 2, one end of the pump body 2 is provided with a water inlet 3, and the water inlet 3 is connected with a high-level water source connecting pipe 1; the other end of the pump body 2 is connected with a water outlet 4. The water outlet 4 is connected with a water outlet valve 5, and the water outlet end of the water outlet valve 5 is connected with a water outlet pipe 6; the water outlet valve 5 is an intermittent opening and closing valve. The water outlet valve 5 can be opened and closed intermittently, when the water flow speed is high, the valve is closed suddenly, the water flow stops flowing, but the water flow has mass and can generate extremely high pressure on the tail end of the water flow under the action of inertia.

The liquid level that high-order water source connecting pipe 1 connects is higher than the liquid level that drain pipe 6 connects. The difference between the liquid levels of the high-level water source connecting pipe 1 and the water discharging pipe 6 can form running water in the pipeline.

Furthermore, a high-pressure water outlet 7 is formed in the side face of the pump body 2, and the high-pressure water outlet 7 is connected with a one-way valve 8; the input end of the one-way valve 8 is connected with the high-pressure water outlet 7, and the output end of the one-way valve 8 is connected with the water sump 9.

Further, the upper half part of the water sump 9 is a high-pressure air chamber 10; a water outlet pipe 11 is connected to the side surface of the bottom of the water sump 9; the water outlet pipe 11 is connected with a pressure limiting valve 12. The water body oxygenation equipment is a spray type oxygenation device. The kinetic energy water pumping device can convert the kinetic energy of water flow into a high-pressure water source and then spray the high-pressure water source, so that the oxygen concentration of the water body is increased, the whole equipment does not need to consume energy, and the safety of the equipment is improved. The input end of the pressure limiting valve 12 is communicated with the spray type oxygenation device through a pipeline.

The spraying type oxygen increasing device comprises a bifurcated pipe 13, the input end of the bifurcated pipe 13 is connected with a pressure limiting valve 12 through a pipeline, the bifurcated pipe 13 comprises a plurality of output pipes, and the output pipes are connected with spray heads 14.

In the specific operation process, water enters from the high-level water source connecting pipe 1, then passes through the pump body 2 and the water outlet valve 5, and finally is discharged from the water discharge pipe 6. Because the water surface connected with the high-level water source connecting pipe 1 is higher than the liquid surface connected with the drain pipe 6, the speed of water flow is accelerated under the action of gravity, and when the speed reaches a certain value, the water outlet valve 5 is automatically closed suddenly. Under the action of inertia, water in the pump body 2 can generate a large pressure, the one-way valve 8 is pushed to be opened under the high pressure, and water flows into the water bin 9 through the one-way valve 8. The sump 9 is filled with high pressure gas and the one-way valve 8 closes when the pressure in the pump body 2 is lower than the pressure in the sump 9.

When the pressure is lower than a certain value, the water outlet valve 5 is opened, the water flow is accelerated under the action of gravity, and when the pressure reaches a certain value, the process is repeated.

Meanwhile, when the pressure in the water sump 9 is higher than the pressure limiting valve 12, water is discharged from the water sump 9 through the pressure limiting valve 12, then passes through the branch pipe 13 and is sprayed out of the spray head 14, and the forehead water sprayed out of the spray head 14 is in large-area contact with air, directly absorbs oxygen in the air and finally falls into the water body. Therefore, the oxygen content of the river water can be greatly increased, and the degradation speed of organic matters in the river water is increased; and can relieve the living environment of animals in river water, improve the activity and the quantity of aquatic organisms and further reduce the propagation of algae.
