However, when the outside temperature is low in winter, the activity of microorganisms decreases rapidly. In addition, microbial carriers such as microbial boxes and microbial films in this method have the disadvantage of easy loss of microorganisms, which also limits the promotion of this method.
[0004] CN202116385U discloses a kind of oxygen-increasing circulation running water machine composed of a circulation machine and an aeration machine, which mainly generates ultra-fine air bubbles through high-speed gyrations, and then diffuses into the water after being mixed by a stirring device formed by a motor combined with gears and blades. 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. The surface water is sucked to the bottom by the push-flow pump installed at the bottom, thereby achieving the purpose of increasing oxygen. However, this method has a limited oxygenation efficiency
CN206213034U discloses a kind of oxygen-increasing live water machine that is made up of motor, impeller and wheel disc, this kind method drives the impeller to rotate to produce ripple in water to water body oxygenation by motor, but this kind method can not oxygenate deep water body, increase The effect of oxygen is not obvious
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
[0005] 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 by the microporous device is insufficient, and there are shortcomings such as high manufacturing and processing precision and easy blockage
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 a low efficiency of dissolving air and cannot form a supersaturated solution
CN205575786U discloses a jet-type micro-nano aeration system, which has the disadvantages of complex flow channel 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. The gas port is set in the gas-liquid mixer, resulting in a low pressure in the mixer and limited dissolved gas
CN206407964U discloses a kind of suspension type micro-nano aeration device that is made up of submersible pump and injector, forms negative pressure in injector and sucks in air during this device work, gas-liquid mixed liquid is ejected to form micro-bubble afterwards, this kind of method also There is a deficiency of low dissolved gas
[0006] CN107055651A discloses a dosing device composed of a stirring box, a motor, a booster pump, a regulating tank and a sedimentation bin, etc., the device puts the medicine into the stirring tank and is stirred by the motor, and then enters the regulating tank through the booster pump. When in use, it is necessary to set up a separate motor system to stir the medicine, and the energy consumption is high in long-term use

Description

technical field [0001] The invention relates to an ecological running water device, in particular to an in-situ ecological running water device. Background technique [0002] 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. [0003] 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...
