The micro-nano bubble generator is composed of a generating device and a releasing device, and mainly comprises a micro-nano bubble generator, a dissolved gas tank, a gas explosion tank, and a gas explosion head. When the gas enters the micro-nano bubble generating device through the intake pipe, it is thoroughly mixed with the raw water, and processed by high-speed rotary cutting and fine mixing to form micro-nano bubbles with a diameter of less than 50μm, and then released in the form of explosive gas by a release device.
The scouring and silting system is mainly composed of scouring and silting pumps, silting heads and their corresponding connecting pipes. It relies on the strong pressure and impact force generated by the scouring and silting pumps to fully scour the bottom sludge in the water, so that the sludge is fully mixed and degraded with enzymes to achieve good ecological effect of degrading sludge.

Micro-nano bubble characteristics
(1) Long stay in water
When a general bubble is generated in water, it will quickly rise to the surface of the water and rupture and disappear, that is, the existence time is short. Microbubbles can be tens of seconds or even minutes in the water from the production to the final rupture. According to research data, the bubble with a diameter of 1 mm has a rising speed of 6 m/min in water, and the bubble with a diameter of 10 μm has a rising speed of 3 mm/min in water. It can be seen that the microbubbles rise very slowly in water, so they can stay in the water for a long time.
The surface of the micro-bubble is negatively charged, and the negative charge is relatively high compared with the ordinary bubble. Generally, the surface load of the bubble below 30 μm is about -40 mV, which is also the time when the micro-bubbles can be gathered together for a long time without breaking. one of the reasons. By utilizing the negative charge of microbubbles, it is possible to adsorb positively charged substances in water, which has a good effect on the adsorption and separation of suspended solids or pollutants in water.
(3) Self-pressurization and dissolution
The pressure inside the bubble is related to the surface tension. The diameter of the bubble is about small, and the internal pressure is larger. Because the diameter of the micro bubble is small and the specific surface area is large, its internal pressure is much higher than the pressure of the external liquid. It is precisely due to the advantages of the internal pressurization and large specific surface area of the micro-bubble that its dissolving capacity of gas is hundreds of times that of millimeter-level bubbles.Because solubility has a lot to do with pressure, when the internal pressure of the microbubbles increases to a certain value, the interface will be supersaturated. When more gas in the bubble is dissolved into the water, it will slowly dissolve and disappear .
Micron bubbles are constantly shrinking or expanding due to their own pressurization, and their diameters are constantly changing. According to the latest research, bubbles of 20μm~40μm will shrink to about 8um at 1.3μm/s, and then the shrinkage speed will increase sharply. After that, it may further split into nano-sized bubbles or completely dissolve in water.
(5) High dynamic potential of the interface
The surface of the microbubble will adsorb charged ions such as OH-, and around the OH-ion layer, a counter-charged ion layer such as H+ will be distributed, so that the surface of the microbubble forms an electric double layer, and the interface of the electric double layer The potential is also called the interface dynamic potential, and the interface dynamic potential determines the adsorption performance of the microbubble interface to a large extent. Because of the shrinkage of the microbubbles, the charge ions accumulate at the interface of the bubbles in a large amount of time. Until the bubble completely ruptures and dissolves, the interfacial electromotive force always increases, showing that the adsorption performance of the charged particles in the water is better.
(6) generating free radical ions
Generally, in the case of water, the microbubble below 10 μm shrinks, and the density of the electric charge in the electric double layer increases rapidly until the bubble bursts, and the positive and negative electric charge that has reached a very high concentration releases the accumulated energy, resulting in the release of energy. A large number of free radical ions, such as oxygen ions, hydrogen ions, hydroxide ions, and the like. Among them, the hydroxyl radical has a strong oxidation effect, which can oxidize and decompose some organic pollutants that are difficult to degrade, and has a good effect of purifying water quality.
(7) High oxygen mass transfer efficiency
In the process of detonating wastewater treatment, the mass transfer efficiency of oxygen is one of the important factors affecting the efficiency of wastewater treatment, and the size of the bubble diameter is inseparable from the mass transfer efficiency of oxygen during gas explosion. Since the microbubbles have a large specific surface area, they can stay in the water for a long time, and their own superchargeability makes the mass transfer efficiency of the gas-liquid interface continue to increase.
