Supply China Sewage Shallow Air Flotation Machine for Waste Water Treatment

First, the useSolid and liquid separation technology and equipment are one of the key projects in the water supply and drainage treatment process. Air floating is one of the effective methods for the removal of tiny suspended particles with a specific gravity close to water.The equipment is widely used in water supply and drainage treatment projects. First, it should be applied to water plants with lakes as the source of water to reduce algae turbidity, second, it should be applied to industrial sewage treatment projects, such as petrochemical, textile, printing and dyeing, electroplating, tanning, food industry and other fields, and third, it should be applied to the recovery of useful substances in sewage, such as papermaking, pulp and water fiber recovery and other fields. Second, the model representation methodGQF -  - Processing capacity (m3/h).High-efficiency shallow airfly Product features Third, characteristicsThe effective water depth is shallow, 750 to 950mm.The water stay in the pool is short (5 to 10min).The amount of purification is large, i.e. the surface load is high.The area is small, the unit load is light, all prefabricated components are assembled, no need for operating room, equipment can be installed overhead, can also be combined in multiple layers.Installation and maintenance costs are low and easy to clean.The degree of purification is high, the removal rate of suspended substances such as algae is more than 90%, and the concentration of sludge after concentration is 35%.The device uses GFA-type dissolved gas system, it is cleverly structured, soluble efficiency of up to 90%, has a number of patented technology, with other gas-soluble devices do not have the super anti-clogging ability.Fourth, the construction and work processAir float separation technology refers to air and water at a certain working pressure, so that the gas more limited dissolved into the water, and strive to be in a saturated state, and then the resulting pressure-soluble air and water through decompression release, produce a large number of micro-bubbles, and the water suspended flocs full contact, so that the suspended flocs in the water adhere to the micro-bubbles, with bubbles floating to the surface, forming a scum and scraping off the slag, thus purifying the water.GQF-type high-efficiency shallow air floating device developed by the source company is an advanced rapid air floating system, which, on the basis of the traditional airfleet theory, has successfully applied the "light layer theory" and "zero-speed principle", through careful design, set flocculation, floating, slag removal, scraping mud as a whole, is an efficient equipment for water purification treatment. ""GQF-type high-efficiency shallow air floating device for the shortcomings of the traditional floating pool, its raw water import and purification of water outlet designed to move, in order to shorten the floating time of the original water bubbles, that is, the original water flow to the air floating pool at the same time, the pool cloth pipe to the original water flow in the opposite direction, so that the raw water into the pool is basically in a relatively stationary state, Thus the bubbles in the water float to the surface vertically, floating speed close to the floating speed of solids in the raw water (4 to 250px/min), so the suspended matter in the raw water can quickly surface the surface, and the purified water under the slag is still in place, when the purified water collection pipe moved here, the purified water can be discharged out of the pool. In order to make the inlet and outlet can move synchronously, the machine is designed to be round, the inlet and exit pipes are placed on the turning frame, so that it rotates around the center, this moving cloth water way produces "zero speed". Suspended matter in raw water floats from water to surface quickly, and in three minutes raw water can meet purification requirements.The device is cylindrical as a whole, compact in structure and shallow in pool. It includes the pool body, the spiral cloth water mechanism, the soluble gas release mechanism, the rotating frame, the water collection mechanism, the slag-throwing mechanism, the solubility system, the return water pipe and the electronic control cabinet and other components. The inlet, outlet and sludge outlet are all in the rotating area of the equipment, and the cloth water distribution mechanism, water collection mechanism and soluble release mechanism are closely connected with the frame and rotate around the center of the pool. This device provides a complete set of equipment assembly and control system, through the combination of centralized control and decentralized control, so that the equipment to achieve better operating conditions.Product Parameters Fifth, the main technical skills:Table 1  The amount of processing10~800m3/hThe reflux ratio30%The pool is deep900~1100mmDissolved water pressure≥0.4 MPaEffective water depth75
