Abstract

PURPOSE:To provide the titled apparatus developing excellent treating capacity by uniformizing the interior of a treating water tank to promote oxidation, constituted so as to be capable of forming effective flow to treating water in the treating water tank by an emitted liquid due to pump injection, a suction stream due to emitting negative pressure and a suction stream due to the movement of air bubbles. CONSTITUTION:Water to be treated is sucked into a treating water tank 3 by a submerged pump 13 and injected into a water flowline 4 opened into the water tank 3. By this operation, circumferential water to be treated is sucked and flowed into the flowline 4 by injection negative pressure and emitting negative pressure to generate convection like flow throughout the water tank 3 and successively passed through the flowline 4. In this case, water to be treated sucked and flowed into the flowline 4 is brought into effective contact with O2 in air sucked by injection negative pressure from a jet pipe 9 to perform oxidative removal of impurities such as SO3 or SS in water to be treated.

[The water to be treated that is sucked by the pump is passed through an ejector, where air is introduced, and the water is returned to the tank to be treated for oxidation treatment. In addition to the small amount sucked into the pump, the efficiency of stirring and mixing in the water tank to be treated is extremely low, resulting in poor treatment efficiency of the water to be treated and the drawback that it cannot cope with the large amount of wastewater generated.

。The present invention forms an effective flow in the water to be treated in the water tank by forming a discharge flow by pump injection, a suction flow by negative discharge pressure, and a suction flow by bubble movement.
The purpose of this project is to provide a treatment device that homogenizes the inside of the water tank to be treated in a short time and promotes oxidation, thereby providing excellent treatment capacity. At least one of the openings is arranged in the water tank to be treated below the liquid level of the water to be treated, and the opening at one end of the water flow passage which is below the liquid level is used to suck and spray the water to be treated towards the opening at the other end. The gist of the present invention is an apparatus for treating polluted water, such as oxidation, characterized in that a jet injection pipe and a gas supply port protrude or face each other leaving a suction space for water to be treated.

A passage pipe 5 is vertically supported, and one end opening 6 of the passage pipe 5 opens toward the bottom of the water tank 3 to be treated, and the other end opening 7 opens upward. Collision plates 8 for flow direction are supported facing each other, and a jet injection pipe 9 emerges from the opening 6 at one end with its injection direction directed upward into the passage pipe 5 and leaving a suction space 10 for the water to be treated. There is. The jet injection pipe 9 has an in-tube nozzle 11 and an air introduction pipe 12 serving as a gas supply port is connected to the pipe wall on which negative injection pressure acts. The pipes are arranged so that the water to be treated sucked in from 13 is supplied and injected.

不純物例えばｓ０３．ｓｓ等を酸化除去するのである。The gist and examples of the device of the present invention have been explained above, and the device of the present invention sucks the water to be treated in the water tank to be treated with a pump,
When the water is injected into the water passageway that opens into the water tank, the surrounding water to be treated is sucked into the water passageway by the negative injection pressure and discharge negative pressure, creating a convective flow throughout the water tank. The water is generated and sequentially passes through the flowing water passage. The water to be treated that has been suctioned into the water passage comes into contact with the oxygen in the air sucked in by the negative pressure from the jet injection pipe or the oxygen that is forcibly supplied, thereby removing impurities such as impurities in the water. s03. It removes ss etc. by oxidation.
