domestic sewage treatment integrated device mainly relies on the AO+ filtration treatment process in the equipment to remove organic pollutants and ammonia nitrogen. The working principle is that in the A-level, due to the high concentration of organic matter in the sewage, the microorganisms are in a gas-deficient state. At this time, the microorganisms are facultative microorganisms. They convert and decompose the organic nitrogen in the sewage into NH3-N, and use the organic matter as an electron donor at the same time. , converts NO-N.NO-N into N. In addition, some organic carbon sources and NH-N are used to synthesize new cellular substances, so the A-level pool not only has a certain function of removing organic matter, reducing the organic load of the subsequent aerobic pools to facilitate digestion, but also depends on the presence of raw water. The higher concentration of organic matter can complete the reverse digestion, and finally eliminate the eutrophication of nitrogen pollution. At the O level, the concentration of organic matter has been greatly reduced, but there is still a certain amount of organic matter and high NH-N. In order to further oxidatively decompose the organic matter, and at the same time, the digestion can proceed smoothly when the carbonization is completed, a good biological contact oxidation tank with low organic load is set up in the O-level tank. In the O-level tank, there are mainly aerobic microorganisms and auto-oxygen Type bacteria (digestive bacteria), in which aerobic microorganisms decompose organic matter into CO2 and H2O, and self-aerobic bacteria (digestive bacteria) use the inorganic carbon produced by the decomposition of organic matter or CO2 in the air as a nutrient source to convert NH3- N is converted to NO-N.NO-N. The effluent part of the O-class pool is returned to the A-class pool to provide electron acceptors for the A-class tank.
. The IWP-A2O domestic sewage treatment integrated device occupies a small area, has no impact on the surrounding environment, has less sludge output, and has a noise lower than the standard of the second-class area.
2. IWP-A2O sewage treatment integrated equipment is composed of carbon steel structure anti-corrosion, and anti-corrosion coating is used for anti-corrosion. With acid, alkali, salt, gasoline, aging, abrasion resistance, rust and rust. After the equipment is generally painted, the anti-corrosion life can reach more than 10 years.
3. The A2O biological treatment process in the IWP-A2O domestic sewage treatment integrated device adopts the plug-flow biological contact oxidation tank, and its treatment effect is better than that of the complete mixing type or the two- and three-stage series fully mixed biological contact oxidation tank, and it is Compared with the activated sludge tank, the volume is smaller, the adaptability to water quality is strong, the impact resistance is good, the water quality of the effluent is stable, and no sludge bulking occurs. , Microbial hanging film, easy to remove film, under the same organic load conditions, the removal rate of organic matter is higher than other fillers. It can improve the solubility of oxygen in the air in water.
