Level 3 biological treatment of sewage depths

Level 3 biological treatment of sewage depths Working principle: High density - precipitation air-float adopted tiny bubbles happen technology, times surface capture technology, counter-current principle technology, separate zone laminar principle technology, efficient tube type dosing coagulation technology, scum circulation flocculation technology, sludge precipitation collection in seven aspects of core technology, high separation of suspended solids, sewage system cleverly put air-float and precipitation two craft set in a pool in the body. Accounts for approximately 10% 100% of the total water after processing water efficiently dissolve gas recycling. Circulating water and wastewater and the mixture among elixir in a specially designed efficient tube type dosing coagu-flocculation device completed. Large generated floc properties in high density of tiny bubbles in the environment to generate and grow up. A specially designed equilibrium release device, obtains the average diameter for 2 apms m tiny bubbles, high density of tiny bubbles huge surface area provides adsorption tiny aerosols ability. Tiny bubbles adhesion in aerosols on the mild after mixing from the bottom to enter air-float slots. First of all a rapid rise in suspended particles floating in the rapid rise in liquid surface area rapid forming light slag layer. High density - precipitation air-float most special place is that it again let sewage specially designed times surface capture device, so that those who rise slowly buoyancy slightly higher than the gravity of small particles and small micro bubble be intercepted and moved to times surface gradually condenses into larger floc properties, when these floc properties of buoyancy increase gradually, they were not subject to any disturbance and flow obstacles to the water under the condition of the floatation of light slag layer. Part of suspended solids precipitation by special on the bottom of the sludge collection devices collect emissions. Significant advantage: 1.Floating and precipitation of clever confluence, very suitable for high concentrations of complex sewage treatment. 2. High efficiency, each hour can reach 8 - as/h (efficient special design) 3. Emissions of sludge concentration high, up to 30 - is 100 gold/L. 4. High-quality water. 5.The operating cost is low, and the existing process than saving 10-30% of the potion. 6. High impact load 7. Equipment maintenance free, bottom installs a automatic cleaning system, row mud when automatic cleaning bottom. application In paper industry whitewater clarification and fiber recycling Chemical industry, steel and iron, food and so on in industrial wastewater physico-chemical treatment Industrial waste water floating in solid, oil, grease, organics removal.
