Problems solved by technology

However, in the artificial aeration restoration process, aeration time and aeration intensity become the limiting factors for further cost reduction and efficiency increase. Long aeration time and high aeration intensity do not necessarily promote the coupling of nitrification and anti-harmony in water bodies. effect, and cannot ensure greater removal of endogenous contamination

Embodiment 1

[0063] An aeration device coupled with biofilm purification technology, which includes: an aeration unit, a suspension unit, a microbial unit, and a control unit; The inlet is connected, and the air-water pipe is connected with the outlet of the submersible pump; and the suction pipe is exposed above the liquid surface of the water body, and the submersible pump and the air-water pipe are located below the liquid surface of the water body. The submersible pump provides power for the suction pipe to inhale gas to increase dissolution At the same time, the submersible pump pumps the inhaled gas into the water body through the air-water discharge pipe to increase the dissolved oxygen; the suspension unit is set outside the suction pipe; the microbial unit includes a frame and a suspended filler that fills the frame, and the suspended filler During the treatment of water bodies, it can act as a carrier and form a biofilm on the surface. The microbial unit is located below the liqu...

Embodiment 2

[0065] refer to figure 1 , figure 2 , image 3 As shown, the present invention proposes an aeration device coupled with biofilm purification technology, including: an aeration unit, a suspension unit, a microbial unit and a control unit; the aeration unit is mainly composed of a submersible pump 1, an air suction pipe 2, an air-water The exhaust pipe 3 and the baffle 7 are composed. The submersible pump 1 is connected to the upper suction pipe 2 and the lower air-water discharge pipe 3. The submersible pump 1 is embedded in the microbial unit, and the suction pipe 2 is placed 10-30cm above the water surface. , and the side wall of the suction pipe is provided with a plurality of suction holes. One end of the air-water exhaust pipe 3 extends into the microbial unit and communicates with the outlet of the submersible pump, and the other end extends out of the microbial unit and exposes a section of pipeline. "Y"-shaped structure, the planes where the two air-water pipes are ...

Abstract

An aeration device coupling a biofilm purification technique and an aeration method are disclosed. The aeration device includes an aeration unit, a suspension unit, a microbe unit and a control unit.The aeration unit includes a submerged pump, an air suction pipe and a gas-water discharging pipe which are communicated. The air suction pipe is above the water surface, and the submerged pump and the gas-water discharging pipe are below the water surface. The suspension unit sleeves the air suction pipe. The microbe unit includes a frame, and a suspending filler filling the frame and used for forming biofilm on the surface of the filler. The microbe unit is below the water surface, and is provided with an accommodating cavity used for accommodating the submerged pump. The control unit includes a dissolved oxygen sensor and a control system. Through the aeration device and the aeration method, and on the basis of artificial aeration, biochemical functions of the natural environment itselfare combined, and a microbe enhanced water body restoration technique is coupled. The device and the method have characteristics of convenient installation and a high aeration efficiency.

Description

technical field [0001] The invention relates to the technical field of water restoration in an ecological environment, in particular to an aeration device and an aeration method coupled with biofilm purification technology. Background technique [0002] For a long time, due to random piles of domestic garbage around the water body, domestic sewage and industrial waste water being secretly discharged or leaked into the water environment, the water body has been seriously polluted, resulting in long-term hypoxia, destroying the original ecological system, and directly affecting the environment. To the safety of human living environment and physical and mental health. [0003] "Green water is always there" is an important goal of my country's future ecological civilization construction. In order to alleviate the current serious water ecological pollution, all parties have adopted active governance and restoration measures. After the input of exogenous pollution is effectively ...
