| LSGM three-phase eddy current super air flotation system Introduction to high efficiency and energy saving LSGM three-phase eddy current super air flotation LSGM three-phase eddy current super air flotation equipment technology is an epoch-making innovative product of Shanghai kexuan Environmental Protection Technology Co., Ltd. It can save more operating costs for customers (more than 30% of reagent dosing cost can be saved); Provide better pretreatment efficiency; Reduce the initial investment cost of subsequent biochemical treatment system; As an efficient pretreatment system, it can well ensure the stable and reliable operation of subsequent anaerobic, aerobic and biochemical processes. It can effectively remove suspended solids (TSS removal rate is more than 97%), Oils (fog removal rate is more than 97%) and related chemical oxygen demand (COD) and biochemical oxygen demand (BOD) in complex sewage. It is an excellent pretreatment system. For special wastewater, a small amount of accurate chemicals are used to fully coagulate and flocculate pollutants in water to form hollow flocs with extremely light specific gravity, It floats to the surface of the tank and is scraped off. 1) Reagent use efficiency and reagent mixing Traditional air flotation uses non-invasive reagent mixing, such as flocculation pipe or stirring blade. Each method tries to open the flocculant in the wastewater and prevent it from agglomerating. However, neither method is very effective, because it is difficult for them to fully expand the framework of flocculant monomer. The key principle of LSGM is eddy current three-phase mixing technology. The LSGM air flotation system uses centrifugal force to stretch the flocculants without cutting them off. A set of LSGM air flotation system has five three-phase vortex mixers, and the mixing energy of each can be different. Adjust the mixing energy of each three-phase vortex mixer according to the inlet water quality, application conditions and physical and chemical requirements. Due to the 100% contact between the agent and pollutants, not only the agent consumption is reduced, but also the floc density is greatly improved and the water content of sludge is reduced. 2) Differences in aeration Since LSGM air flotation system dissolves 100% of wastewater under pressure, dissolved gas is added before floc formation. Bubbles grow in flocs. The continuous release of bubbles enables the sludge itself to be continuously dehydrated, and the solid content of scum is very high. So as to reduce the cost of sludge disposal. The system does not need the circulating return pipeline and the dissolved gas release head in the flotation cell. Both parts are easy to be blocked and require a lot of maintenance. As the bubbles grow in the flocs, the continuous release of bubbles makes the sludge float up by itself, and there is no need to introduce air into the flotation cell. Therefore, the floor area of the flotation cell is very small. This also reduces the entrainment of bad flocs in the effluent and the concentration of total oil, suspended solids, BOD and COD in the effluent. In view of the dissolved air efficiency and ultra-high utilization rate of chemicals, the LSGM air flotation system can stabilize the effluent suspended solids concentration at 7 ~ 25ppm if necessary. 3) 100% dissolved gas Unlike most traditional dissolved air floatation technologies, LSGM air floatation system dissolves 100% of wastewater under pressure. This technology enables the LSGM air flotation system to quickly dissolve gas in the wastewater before the addition of chemicals, making it possible for bubbles to be implanted into the floc structure. In addition, the maintenance problems often occurred in the traditional dissolved air flotation of partially dissolved air, such as blockage, will be greatly reduced. The amount of gas dissolved into wastewater makes the system more effective than other technologies. Due to the continuous release of a large number of bubbles in the flocs, the sludge itself can be continuously dehydrated, and the solid content of scum is also very high. Meanwhile, the dissolved oxygen content in the effluent of LSGM air flotation system is also relatively high, reaching 0.9 ~ 2ppm, which is conducive to the operation of subsequent biochemical system. 4) The flow is adjustable and stable Because all steps of high-pressure air dissolution, agent molecule stretching and efficiency improvement, coagulation and flocculation stirring (pollutant capture), floc formation, bubble nucleation and ultra light medium cavitation floc formation are completed in the three-phase vortex mixer. The size of the flotation cell will not greatly affect the treatment flow and pollutant load. The number of holes in the three-phase vortex mixer can be opened or blocked according to the water volume and pollutant concentration. Therefore, LSGM air flotation system is the only product in the market that can allow customers to realize self-regulation. The unique vortex energy regulation function of the three-phase vortex mixer ensures that the LSGM air flotation system can adapt to different water inlet conditions. In case of sudden changes in sewage properties, temperature and flow, it can quickly adapt and adjust the working conditions in time without increasing investment and pool size, so as to ensure stable water outlet. The technical characteristics break through the shortcomings that the traditional chemical treatment process can not adapt to the significant change of water quality, and ensure the stability of the whole sewage treatment process. The perfect design of dosing system can accurately add chemicals according to the incoming water quality, so that the system can always maintain the best treatment effect. 5) Advantages of LSGM system The LSGM air flotation system allows customers to simplify all operations, operate stably and reliably, and provide the following benefits: • Higher removal rate • Higher utilization rate of chemicals (the cost of chemicals can be saved by more than 30% compared with traditional air flotation equipment) • The sludge scum is drier and the sludge is reduced • The treatment flow and pollutant load are flexible and adjustable • The floor area is smaller (more than 50% of the floor area can be saved), and the installation is convenient and simple • There is no tie bar in the pool and no cleaning is required • There is no maintenance problem (there will be no blockage of traditional air flotation dissolved air release head) The LSGM air floatation water inlet pump transmits the pressurized dissolved gas of wastewater from the regulating tank to the three-phase vortex mixer. The chemical dosage of 100% dissolved gas water and the pressure of pressurized gas need to be adjusted according to the situation. Chemicals are added into the LSGM air flotation three-phase vortex mixer, and the treated wastewater is released in the release chamber of the LSGM air flotation system. Since the bubbles grow in the flocs, the continuous release of bubbles makes the sludge float up by itself, and finally a layer of sewage sludge with high solid content is formed on the water surface of the flotation tank. The sludge will be scraped by the slag scraper and collected into the sludge hopper. Slag scraping operation is adjustable. The sludge in the sludge hopper is pumped into the sludge tank through the sludge pump, and then further dewatered. Most of the insoluble pollutants in the wastewater are removed in the LSGM air flotation system, and the effluent enters the next process for treatment.
