Description

An in-situ ecological living water equipment

Technical field

The invention relates to an ecological living water equipment, in particular to an in-situ ecological living water equipment.

Background technique

Since the 21st century, humans have gradually faced various environmental problems. In recent years, industrial wastewater, domestic sewage and other wastes have entered water bodies such as rivers, lakes and seas. The entry of large amounts of nitrogen, phosphorus and other nutrient salts has caused phenomena such as 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 management are facing increasingly severe challenges.

At present, the treatment technologies for polluted water bodies mainly include physical, chemical and biological treatment methods. Physical methods include using various filter materials to adsorb or precipitate filtration of pollutants in the water through adsorption, precipitation, and blocking. Physical methods can effectively increase the transparency of water bodies, solve the black and smelly water bodies to a certain extent, and quickly improve the sensory effects of water bodies, but they cannot fundamentally solve the internal pollution sources of black and smelly water bodies. The chemical method mainly uses various chemicals to convert pollutants in the water into substances that are less harmful to the environment and human body, thereby improving the water quality to meet corresponding standards. Under the current conditions, most chemicals are expensive to use and suffer from secondary pollution problems, so they cannot be widely used. Biological method is a method that uses the metabolic function of microorganisms to absorb or transform organic pollutants existing in dissolved state in sewage. It has the characteristics of low cost and integration with the ecological functions of water bodies. 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 membranes in this method have the disadvantage that microorganisms are easily lost, which also limits the promotion of this method.

CN202116385U discloses an oxygenated circulation water machine composed of a circulation machine and an aerator. It mainly generates ultrafine bubbles through high-speed rotation, and then mixes them through a stirring device formed by a motor combined with gears and blades and then spreads into the water. However, this process The fine bubbles generated by the first-stage gyration have the disadvantage of low dissolved air rate, and the deceleration stirring device composed of motor and gear consumes a lot of energy, has a short lifespan, and has high long-term maintenance costs. CN106315882A discloses a laminar exchange type oxygenating water machine composed of a water collection funnel, a guide tube and a push-flow pump. The surface water is pumped to the bottom through a push-flow pump installed at the bottom of the water, thereby achieving the purpose of oxygenation. However, the oxygenation efficiency of this method is limited. CN206213034U discloses an oxygenating water machine composed of a motor, an impeller and a wheel disc. This method adds oxygen to the water body by driving the motor to rotate the impeller to generate ripples in the water. However, this method cannot add oxygen to the deep water body and increases the oxygen content of the water body. The oxygen effect is not obvious. CN106365333A discloses a fully automatic water treatment equipment driven by solar energy. The three-dimensional circulation of the water body can be realized under the water lifting action of the water conduit impeller of the equipment. However, the device is driven by solar energy and therefore has low power, and it is time-consuming to promote water body circulation. It takes a long time, and the reliability of solar power supply is greatly affected by weather.

CN102219315A discloses a micro-nano oxygenation device composed of a water pump, an accumulator and a wide gap nozzle. The device cuts the gas-liquid mixture through the water pump blades and the nozzle to form fine bubbles, but the gas entering the accumulator is The liquid mixture is only cut by the impeller blades, and the bubbles are not uniform enough so the dissolved oxygen efficiency is limited. CN102001719B discloses a device that generates micro-nano bubbles through a microporous device. However, the bubbles generated through the microporous device have insufficient uniformity, and have shortcomings such as high manufacturing and processing precision and easy clogging. CN203212385U discloses a cyclonic micro-nano aerator driven by solar energy. This device uses high-speed rotating water flow to drive air mixing. However, this method has low air dissolving efficiency and cannot form a supersaturated solution. CN205575786U discloses a jet micro-nano aeration system. This device has shortcomings such as complex flow channel design and cumbersome installation procedures. CN204981362U discloses a micro-nano aeration and oxygenation device composed of a self-priming pump, a gas-liquid mixing fluid tube and a micro-nano generator. The device rotates the gas-water mixture at high speed and then decompresses and releases it to form micro-nano bubbles. However, this method is complicated. The gas port is arranged in the gas-liquid mixer, resulting in a low pressure and limited dissolved gas in the mixer. CN206407964U discloses a suspended micro-nano aeration device composed of a submersible pump and an ejector. When the device is working, a negative pressure is formed in the ejector to suck air in, and then the gas-liquid mixture is sprayed out to form fine bubbles. This method is the same. There is a shortcoming of low dissolved gas content.

CN107055651A discloses a dosing device consisting of a mixing box, a motor, a boosting pump, a regulating tank and a sedimentation bin. The device puts the medicine into the mixing box and stirs it with the motor, and then enters the regulating tank through the boosting pump. The device When used, a separate motor system is required to stir the medicine, and the energy consumption is high during long-term use.

After the granular flocculation medicine enters from the solid medicine storage bin 26, the check valve 27 at the bottom of the medicine bin opens under the action of the gravity of the medicine, and the medicine enters the medicine liquid mixing bin 29, and the micro gear pump 32 Start injecting water into the liquid medicine mixing chamber 29. After the medicine is mixed and dissolved, the one-way valve 30 opens. Under 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 medicine liquid mixing chamber 29 from the liquid medicine storage tank 31. The mixed liquid enters the micro-nano aeration device through the medicine inlet 20. After dilution and mixing, it enters the water body that needs to be treated through the outlet pipe 11;

After the flocculation agent and the biological enzyme agent 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 then evenly diffused to the water body that needs to be treated through the three-dimensional circulation of the water body. The flocculation agent can physically adsorb the tiny particles of suspended pollutants in the water and then flocculate and settle, quickly improving the look and feel of the polluted water body and increasing the transparency of the water body. After the biological enzyme agent is put into the polluted water body, the original indigenous microorganisms in the water quickly recover, which is good for Aerobic bacteria multiply rapidly, the underwater ecological chain is repaired, and the oxidation, decomposition and transformation process of harmful substances is accelerated, which not only solves the internal pollution of the water but also enhances the self-purification ability of the water body;

The circulating water driving device lifts the micro-nano level parent living water formed by the micro-nano aeration device in situ and creates waves outward in the diameter direction, forming a large-scale three-dimensional circulating convection in the water body in the treatment area. The 1.5kW power hydraulic motor 22 drives the impeller 4 to lift water more than 7200m ³ per hour, and the affected water area can be more than 30000m ² . The water body and sediment below are sucked to the surface and then come into contact with air and sunlight, which increases dissolved oxygen while promoting The biological activity in the sediment further promotes the activity of microorganisms and algae in the sediment, plays the dual role of physical oxygenation and ecological oxygenation, and promotes the recovery of the self-purification ability of the water body.
