Description

A flotation sewage treatment machine and treatment method for sewage treatment

Technical Field

The present invention relates to the technical field, and in particular to an air flotation sewage treatment machine for sewage treatment and a treatment method.

Background Art

With the aggravation of water pollution, water resources are becoming less and less. In order to get more water resources, people need to treat and recycle sewage. At present, in terms of water supply and drainage, the pre-treated water quality, except for some raw water with more sand and sewage with heavier mechanical impurities, is mostly light suspended particles, such as: algae in lakes, reservoirs and some rivers; plant residues and fine colloidal impurities; dye particles in the printing and dyeing industry; short fibers in the papermaking and chemical fiber industries; droplets of petroleum and organic solvents in the refining and chemical industries; heavy metal ions in electroplating and pickling wastewater; electrophoretic paint wastewater, etc.; all are light particles with a specific gravity very close to that of water.

For these raw waters, if traditional sedimentation methods are used, the results will inevitably be poor, especially under low temperature conditions in winter, when the treatment effect is more difficult to guarantee due to the deterioration of coagulation and hydraulic conditions.

Therefore, we propose a flotation sewage treatment machine and treatment method for sewage treatment, which introduces tiny bubbles into the sewage, so that the pollutants in the sewage adhere to the surface of the tiny bubbles, make them rise to the surface of the sewage, and then scrape them away. The present invention is very convenient, fast and efficient.

The top of the air inlet pipe is fixedly connected to a middle plate, and curved plates are fixedly installed on both sides of the middle plate. Air cavities are opened inside the middle plate and the curved plate, and an air stone is fixedly installed on the upper surface of the curved plate. The gas blown into the air cavity by the aerator through the air inlet pipe reacts with the air stone to become tiny bubbles, thereby enhancing the adsorption of pollutants by the bubbles. The setting of the curved plate allows space for the gas to rise, so that the entire plate body is filled with tiny bubbles, thereby increasing the distribution range of the tiny bubbles, improving the adsorption range of the tiny bubbles, and enhancing the adsorption effect on pollutants.

Adsorbed on tiny bubbles, the effect of adsorption of pollutants is further enhanced. After the tiny bubbles in the first air collecting bowl and the second air collecting bowl are poured out through tilting, the first foam block and the second foam block on the top of the first L-rod and the second L-rod reset the first L-rod and the second L-rod through buoyancy. At this time, the first stirring plate and the second stirring plate installed on the side of the first L-rod and the second L-rod stir the sewage again to enhance the reaction. The first stirring plate and the second stirring plate are installed in an inclined state, which can minimize the resistance to the sewage while stirring the sewage, saving the setting of the power device while enhancing the reaction effect on the sewage.

The water pipe is fixedly mounted on the top of the water pump, and the water pump has an outlet joined with a stopcock, and the outlet joined with a stopcock is connected with a stopcock. The installation of the power device is reduced, which saves manpower and material resources. The pollutants on the surface of the sewage are scraped and removed while the water is entering. It is very convenient to use.

A water pipe is fixedly connected to the top surface of the medicine bin, and a water outlet is opened on the ground of the medicine bin. The flotation agent is put into the dosing pipe, and the inclined dosing pipe can prevent the flotation agent from being blocked. The slope block in the dosing pipe can crush the flotation agent agglomerates through rolling to prevent the agglomerated flotation agent from affecting the use effect.

Adding the flotation agent can achieve a better flotation effect. It is convenient and quick to use, and saves labor costs.

S1: The sewage to be treated is connected to the water inlet pipe. The sewage stirs the blades to rotate due to gravity. The rotating force causes the first cylinder to rotate. The first cylinder drives the cleaning device to work through the rotation transmission.

S2: Start the aerator to blow gas into the air inlet pipe. The gas enters the air cavity. The curved plate distributes the gas to every corner of the air cavity during the rising process. The gas passes through the air stone and turns into tiny bubbles. Since the air stone is evenly fixed inside the curved plate, the generated tiny bubbles are evenly distributed inside the plate body, so that the pollutants in the sewage are attached to the bubbles and rise to the surface of the sewage. The purified sewage flows into the first drain port, is filtered through the second drain port on the surface of the drain bowl, and then enters the inner cavity at the bottom of the plate body and flows out from the outlet pipe;

S3: tiny bubbles gather in the first gas collecting bowl and the second gas collecting bowl. When the buoyancy of the rising bubbles is greater than that of the first foam block and the second foam block, the first L-shaped rod and the second L-shaped rod tilt to drive the first stirring blade and the second stirring blade to stir the sewage. After the gas in the first gas collecting bowl and the second gas collecting bowl is released, the buoyancy of the first foam block and the second foam block causes the first L-shaped rod and the second L-shaped rod to return to their original positions to stir the sewage again.

S4: Put the flotation agent into the medicine inlet hopper, and the cleaning device starts to work, scraping and removing the pollutants floating on the sewage surface through the linkage effect;

The present invention has the beneficial effects:

The present invention discloses an air flotation sewage treatment machine and a treatment method for sewage treatment. The gas blown into the air cavity by the dissolving machine through the air inlet pipe reacts with the air stone to become tiny bubbles, thereby enhancing the adsorption of pollutants by the bubbles. The arrangement of the curved plate allows the gas to have space to rise, so that the entire plate body is filled with tiny bubbles, thereby increasing the distribution range of the tiny bubbles, improving the adsorption range of the tiny bubbles, and enhancing the adsorption effect on pollutants.

The present invention discloses an air flotation sewage treatment machine and a treatment method for sewage treatment. The air flotation sewage treatment machine utilizes the rising buoyancy of tiny bubbles to collect the tiny bubbles in a first gas collecting bowl and a second gas collecting bowl, and the first L-bar and the second L-bar are tilted so that the first stirring plate and the second stirring plate installed on the sides of the first L-bar and the second L-bar stir the sewage, so that the pollutants are more fully adsorbed on the tiny bubbles, and the effect of adsorbing the pollutants is further enhanced. After the pollutants in the sewage are adsorbed, the purified water enters from the first drain port. The inclined design can well prevent the pollutants from entering the drain angle pipe from above, and the pollutants flow downward into the drain bowl under the influence of gravity. The second drain port on the side of the drain pipe can filter the refined water again to prevent the pollutants from entering. The purified water gathers at the bottom of the inner cavity of the plate body and flows out through the outlet pipe.

The present invention discloses an air flotation sewage treatment machine and a treatment method for sewage treatment. After the tiny bubbles in the first gas collecting bowl and the second gas collecting bowl are tilted and poured out, the first foam block and the second foam block on the top of the first L-bar and the second L-bar reset the first L-bar and the second L-bar through buoyancy. At this time, the first stirring plate and the second stirring plate installed on the side of the first L-bar and the second L-bar stir the sewage again to strengthen the reaction. The first stirring plate and the second stirring plate are installed in an inclined state, which can minimize the resistance to the sewage and stir the sewage at the same time, save the setting of the power device and strengthen the reaction effect on the sewage.

The invention discloses an air flotation sewage treatment machine and a treatment method for sewage treatment. The inclined plate at the top of the inner cavity of the plate body is arranged in an inclined shape, so that pollutants floating on the sewage surface are gathered on the other side, and a second transmission belt is arranged above the other side. The paddle plate on the surface of the second transmission belt scrapes and removes the pollutants. The power source of the second transmission belt comes from the force of the sewage flowing through the water inlet pipe, which reduces the installation of the power device to the greatest extent, saves manpower and material resources, and scrapes and removes the pollutants on the sewage surface while the water is inletting. The flotation agent is put into the dosing pipe, and the inclined dosing pipe can prevent the flotation agent from being blocked. The slope block in the dosing pipe can crush the flotation agent agglomerates through rolling to prevent the agglomerated flotation agent from affecting the use effect. The water flowing downward from the water inlet pipe fills the medicine bin, and the water flow in the medicine bin drives the corner block to rotate, so that the flotation agent is fully dissolved. The addition of the flotation agent can achieve a better flotation effect. The use is convenient and quick, and the labor cost is saved.
