technical field

The utility model relates to an ecological running water device, in particular to an in-situ ecological running water device.

Background technique

Since the 21st century, human beings have gradually faced various environmental problems. In recent years, industrial wastewater, domestic sewage, and other wastes have entered rivers, lakes, seas and other water bodies, and a large amount of nutrients such as nitrogen and phosphorus have entered, resulting in eutrophication of water bodies. As a result, the quality of water bodies is getting worse and worse, blue-green algae outbreaks are frequent, and water resources protection and water environment governance are facing increasingly severe conditions.

At present, there are three main types of treatment technologies for polluted water bodies: physical, chemical and biological treatment. Physical methods include the use of various filter materials to adsorb or precipitate pollutants in water through adsorption, precipitation and barrier methods. The physical method can effectively increase the transparency of the water body, solve the black and odorous water body to a certain extent, and play a role in rapidly improving the sensory effect of the water body, but it cannot fundamentally solve the internal pollution source of the black and odorous water body. The chemical method mainly uses various chemicals to convert the pollutants in the water into substances that are less harmful to the environment and the human body, and then improve the water quality to meet the corresponding standards. Under the existing conditions, most of the chemical agents are expensive to use and have secondary pollution problems, so they cannot be widely used. The biological method is to use the metabolic function of microorganisms to absorb or transform the organic pollutants in the sewage in a dissolved state. It has the characteristics of low cost and integration with the ecological function of water body. However, when the outside temperature is low in winter, the activity of microorganisms decreases rapidly. In addition, in this method, microbial carriers such as microbial boxes and microbial films have the disadvantage of easy loss of microorganisms, which also limits the promotion of this method.

The fine bubbles generated by the first-stage gyration have the disadvantage of low gas dissolution rate, and the deceleration stirring device composed of motor and gear consumes a lot of energy, has a short life, and has high long-term maintenance costs. CN106315882A discloses a laminar exchange type oxygen-increasing living water machine composed of a water collection funnel, a diversion tube and a push-flow pump.

CN106365333A discloses a fully automatic water treatment device driven by solar energy. The three-dimensional circulation of the water body can be realized under the water lifting action of the aqueduct impeller of the device, but the device is driven by solar energy, so the power is low, and it takes time to promote the water body circulation. Longer, and the reliability of solar power supply is greatly affected by the weather.

CN102219315A discloses a micro-nano oxygenation device composed of a water pump, an accumulator and a wide-slit nozzle. The device cuts the gas-liquid mixture through the blades of the water pump and the nozzle to form fine bubbles, but the gas that enters the accumulator The liquid mixture is only cut by the impeller blades, and the bubbles are not uniform enough so the efficiency of dissolved oxygen is limited. CN102001719B discloses a device for generating micro-nano bubbles through a microporous device, but the uniformity of the bubbles generated through the microporous device is insufficient, and there are disadvantages such as high manufacturing and processing precision and easy clogging. CN203212385U discloses a swirl type micro-nano aerator driven by solar energy. The device utilizes high-speed swirling water flow to drive air mixing, but the method has low air-dissolving efficiency and cannot form a supersaturated solution. CN205575786U discloses a jet-type micro-nano aeration system, which has the disadvantages of complex flow path design and cumbersome installation procedures. CN204981362U discloses a micro-nano aeration and oxygenation device made up of a self-priming pump, a gas-liquid mixed fluid pipe and a micro-nano generator. The device decompresses and releases the gas-water mixed liquid at a high speed to form micro-nano bubbles.

After the further cutting and refinement of the sealing spoiler 36, the air bubbles are refined to the micro-nano level, the gas-liquid mixture is pressurized and dissolved in the gas-dissolving tank 9 to reach 100% saturation, and the dissolved oxygen content is greater than 10mg/L, and the gas-liquid mixture is passed through the Venturi tube 10 After decompression spraying, the bubbles further form uniform micro-nano bubbles with a diameter of 30-50μm, and the smallest diameter bubbles can be as small as 30nm;

The power source of the high-speed double-suction pump 13 is a submersible permanent magnet motor, which can pump up to 30% of the gas-liquid ratio mixture, and the working efficiency far exceeds 45%. Due to the characteristics of large specific surface area and slow rising speed, micro-nano bubbles can remain in water for a long time, and can provide sufficient active oxygen for good microorganisms, phytoplankton and organisms, and accelerate the degradation of polluting microorganisms in water bodies and sediments. process. At the same time, the micro-nano bubbles have a large specific surface area and have a good adsorption effect on suspended pollutants. When micro-nano bubbles burst, high temperature and high pressure are generated, and more hydroxyl radicals are generated in water, which further promotes the decomposition of high-molecular organic matter.

The drug injection device is installed above the hydraulic mechanism 3. After the granular flocculation drug enters from the solid drug storage bin 26, the check valve 27 at the bottom of the drug bin is opened under the action of drug gravity, and the drug enters the drug liquid mixing bin 29, and the micro gear pump 32 Start to inject water into the liquid medicine mixing chamber 29. After the medicine is mixed and dissolved, the one-way valve 30 is opened. Under the action of the negative pressure generated by the high-speed double-suction pump 13, the mixed liquid enters the micro-nano aeration device through the medicine inlet 20 and is further mixed evenly. The enzyme medicine enters the liquid medicine mixing chamber 29 from the liquid medicine storage tank 31, and the mixed liquid enters the micro-nano aeration device through the medicine inlet 20, and enters the water body to be treated through the outlet pipe 11 after dilution and mixing;

After the flocculation agents and bio-enzyme agents enter the water body through the outlet pipe 11, the mixed liquid is lifted by the strong water lifting capacity of the impeller 4 and spread evenly to the water body to be treated through the three-dimensional circulation of the water body. Flocculation agents can physically adsorb tiny particles of suspended pollutants in water and then flocculate and precipitate, quickly improving the perception of polluted water bodies and enhancing the transparency of water bodies. Oxygen bacteria reproduce rapidly, the underwater ecological chain is restored, and the oxidative decomposition and transformation process of harmful substances is accelerated, which improves the self-purification ability of the water body while solving the source pollution of the water body;

The circulating running water driving device lifts the micro-nano-scale parent running water formed by the micro-nano aeration device in situ and spreads it outward along the diameter direction to form a large-scale three-dimensional circulation convection of the water body in the treatment area. The 1.5kW power hydraulic motor 22 drives the impeller 4. The water lifting capacity per hour is greater than 7200m ³ , and the affected water area can be greater than 30000 m ² . It improves the biological activity in the bottom mud, further promotes the activity of microorganisms and algae in the bottom mud, plays a dual role in physical oxygenation and ecological oxygenation, and promotes the recovery of the self-purification ability of water bodies.
