[0002] Among the existing river water environment treatment technologies, river water purification mainly adopts chemical disinfection or ultraviolet disinfection. These methods may have an impact on the water environment and the effects are not lasting, because traditional wastewater treatment methods cannot effectively degrade persistent components, and membrane filtration and adsorption cannot completely degrade pollutants, but can only separate them from wastewater, thus causing secondary pollution.

[0003] Although people have been researching efficient, economical and energy-saving river wastewater treatment technologies for many years, river water purification technology is still not perfect, with problems such as low efficiency and prone to secondary pollution. Utility Model Content

[0004] In order to solve the technical problem of wastewater treatment, the utility model provides an oxygenation and purification treatment device for a river.

[0006] As a further improvement of the above scheme, the sewage filtering mechanism includes a No. 1 filter station connected to the hydraulic air pipe, one end of the No. 1 venturi tube is connected to the No. 2 filter station, limit grooves are provided in the No. 1 filter station and the No. 2 filter station, and detachable filter nets are provided on the inner sides of the two limit grooves, a water pump mechanism for injecting sewage is provided on one side of the No. 1 filter station, and a detection circulation mechanism for detecting the treated sewage is provided on one side of the No. 2 filter station.

[0007] As a further improvement of the above solution, the air pump mechanism includes an air intake pipe connected to the upper side of the hydraulic air pipe, and the upper end of the air intake pipe is connected to the air pump.

[0008] As a further improvement of the above scheme, the water pump mechanism includes a water supply pipe connected to one side of the first filter station, the upper end of the water supply pipe is connected to a water pump, and the upper side of the water pump is connected to a water inlet pipe.

[0009] As a further improvement of the above scheme, the detection circulation mechanism includes an outlet pipe connected to one side of the No. 2 filter station, the upper end of the outlet pipe is connected to an intelligent detection unit, the upper side of the intelligent detection unit is connected to a drain pipe, and one side of the intelligent detection unit is provided with a circulation reflux pipe mechanism for returning the treated unqualified sewage.

[0010] As a further improvement of the above solution, the circulating return pipe mechanism includes a circulating return water pipe connected to one side of the intelligent detection unit, and one end of the circulating return water pipe away from the intelligent detection unit is connected to one side of the water pump.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model can pump micro bubbles with a diameter of <100μm and >1um into sewage through an air pump. According to research, micro bubbles can produce oxidative hydroxyl radicals even in ordinary water, so that the micro bubbles have a certain ability to degrade organisms and microorganisms in water. In addition, the Zeta potential of the surface of the nanobubble is negative, and the negative charge on the surface can also facilitate the bubbles to adsorb fine impurities in the water. Compared with ordinary bubbles, the specific surface area of ​​microbubbles is larger, that is, the total surface area / total volume value is larger, which can make the gas and liquid phases have a larger contact area and a higher gas solubility rate, thereby improving the efficiency of cavitation bubble generation and further improving the cavitation efficiency.

[0013] 2. The utility model sets a No. 1 Venturi tube and a No. 2 Venturi tube in parallel, and through the double parallel orifice plate hydraulic cavitation technology, the sewage degradation effect and the heat generation efficiency are enhanced. In the optimized parallel system, 4+4 holes in parallel orifice plates are used, the inlet pressure is 3.0 bar, the total solution volume is 5.0L and the initial concentration is 10mg / L. Under the experimental conditions, in the continuous circulation process of 90 minutes, and at 48.50USD / m 3 The cost of generating 785.40 kJ of heat reaches 29.09% thermal efficiency. When BV-1:H 2 O 2 =1:30, the thermal efficiency reaches 33.69%, thereby effectively strengthening the orifice plate hydraulic cavitation to degrade organic dyes on a large scale and utilize heat sources as resources.

[0023] Through the above technical solution, the filter screen 16 is provided in multiple layers and fixed in the pipeline to ensure that solid particles and algae in the water are filtered and the pipeline will not be blocked due to long-term operation of the system. The second filter station 9 and the first filter station 4 are detachable to facilitate the replacement and maintenance of the filter screen.

[0024] Please combine Figure 1 As shown, the air pump mechanism includes an air intake pipe 5 connected to the upper side of the hydraulic air pipe 15, and the upper end of the air intake pipe 5 is connected to the air pump 6.

[0025] It should be noted that a one-way valve is provided on the air intake pipe 5. The one-way valve switch includes a one-way switch, an air intake pipe, and a buckle. The one-way switch and the buckle are arranged in the air intake pipe in sequence and are set to a one-way switch type.

[0026] The water pump mechanism includes a water supply pipe 3 connected to one side of the first filter station 4, the upper end of the water supply pipe 3 is connected to the water pump 2, and the upper side of the water pump 2 is connected to the water inlet pipe 1.

Then, the treated sewage enters the intelligent detection unit 11 along the outlet pipe 10. When it is detected that the treated water quality does not meet the standard, the switch is turned on to send the water back to the water inlet pipe 1 at the water pump 2 through the circulating return pipe 13 for a new round of circulation purification to ensure the oxygen increase and water quality.
