The aquaculture ecological water purifying system comprises a feeding part 101, a gas-water mixing part 102, a biological purifying part 103, a material storage part 104, a waste collection box 105 and a rich water collection box 106.
The feeding part 101 is used for realizing the collection of sewage and oxygen of the water body purifying device. The air-water mixing part 102 is used for realizing superposition mixing of sewage to be treated and oxygen so that the sewage to be treated realizes saturation to supersaturation of dissolved oxygen of water. The biological purification section 103 is used for realizing sewage purification treatment by biological action. The material storage part 104 is used for storing biological colonies for sewage treatment. The waste collection bin 105 is used for waste materials generated in the mobile phone sewage treatment process. The oxygen-enriched water collection tank 106 is used for completing collection of the treated water body.
Preferably, the feeding portion 101 includes at least an air intake portion 107 and a sewage collection portion 111. The air inlet 107 is used for collecting oxygen or other gases by the device. The sewage collection section 111 is for completing the collection of sewage to be treated.
Preferably, the air inlet portion 107 is connected to the air-water mixing portion 102 via an air pressure control box 115.
Preferably, the air inlet 107 includes a blower, an air inlet 108, a gas compression tube 109, and an air outlet 110. The fan is positioned at the end part of the air inlet 108 and is a gas collection power device of the air inlet part 107.
Preferably, the gas inlet 108 is connected to the gas compression tube 109, the gas compression tube 109 is connected to the gas outlet 110 via a connection rib, and the gas outlet 110 is connected to the gas pressure control box 115. So that an open cylindrical cavity is formed between the gas compression tube 109 and the gas outlet 110.
Further, the gas inlet 108 is cone-shaped and has an opening section that gradually decreases in a direction approaching the gas compression tube 109; the gas outlet 110 is conical and has an opening section that gradually increases in a direction away from the gas compression tube 109. The structure of the air inlet 108, the air compression pipe 109 and the air outlet 110 is used for forming an air suction device with venturi effect.
The structure of the air inlet 108 makes the air entering the air compression tube 109 have a higher flow rate, so that the two sides of the cylindrical cavity behind the air compression tube 109 have a negative pressure phenomenon, and the external air flows into the cylindrical cavity formed between the air compression tube 109 and the air outlet 110 through the negative pressure effect, thereby further increasing the air flow entering the air outlet 107.

Preferably, at least one ultrasonic generator 118 is provided at the bottom of the air-water mixing part 102. The ultrasonic generator 118 is used for crushing oxygen bubbles sprayed out through the air spraying channel 117, so that the sprayed large bubbles are changed into molecular-level or atomic-level bubbles, the contact area between sprayed oxygen and sewage in the cavity is increased, and the sewage dissolved oxygen probability is increased. Meanwhile, the ultrasonic action of the ultrasonic generator 117 on the air-water mixture aggravates the thermal motion of each molecule or atom of the mixture, thereby further increasing the sewage dissolved oxygen rate.
Further, at least two air injection channels 117 are provided at the bottom of the air-water mixing part 102. The jet channel 117 is used for introducing oxygen into the air-water mixing part 102.

Further, when the high-pressure water body is fed into the biological purification part 103 from the air-water mixing part 102, the high-pressure water body is in an atmosphere communicated with the outside, so that under the condition of eliminating the outside pressure, part of dissolved oxygen or other gases in the original high-pressure water body are changed from particulate gases into bubbles and rise to the water surface, particles or flocculent suspended matters in the water body can be carried along in the rising process of the bubbles, and an impurity aggregation layer carrying a large number of particles or other suspended matters is formed on the surface layer of the water body.
Further, the water purification system can control the second water pump 121 to move on the guide rail so as to reach the impurity accumulation layer on the surface of the water body, and convey the impurity-containing sewage into the waste collection box 105, thereby realizing the primary purification of the water body in the biological purification part 103.
Preferably, a material storage part 104 is arranged at the top end of the biological purification part 103, and photosynthetic bacteria biological strains are stored in the material storage part 104 and used for completing the absorption of elements such as nitrogen, phosphorus, potassium and the like in the water body, thereby realizing the purification of the water body.
Preferably, a strip-shaped light source 119 with controllable wavelength is arranged at the bottom end of the material storage part 104, and the light source 119 is used for generating illumination with the wavelength required by the colony. The bottom of the chamber of the biological purification part 103 is provided with a temperature adjusting unit 120 for completing the adjustment of the temperature of the water body in the chamber of the biological purification part 103 so as to ensure that bacterial colonies in the water body are at the optimal growth temperature, thereby improving the processing capacity of the bacterial colonies on the water body.
The foregoing examples merely illustrate specific embodiments of the invention, which are described in greater detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
