★Working Principle

The removal of organic pollutants and ammonia nitrogen by HTM-AO series integrated sewage treatment equipment mainly depends on the AO biological treatment process in the equipment. In Class A, due to the high concentration of organic matter in sewage, the microorganisms are in anoxic state. At this time, the microorganisms are facultative microorganisms. They convert and decompose organic nitrogen in sewage into NH3-N, and use organic carbon as an electron donor to convert NO2--NNO3--N into N2, and also use part of the organic carbon source and NH3-N to synthesize new cell substances. Therefore, the Class A pool not only has a certain organic matter removal function, reduces the organic load of the subsequent aerobic pool, so as to facilitate nitrification, but also relies on the higher concentration of organic matter in the raw water to complete denitrification and ultimately eliminate nitrogen eutrophication pollution. In Class O, since the concentration of organic matter has been greatly reduced, there is still a certain amount of organic matter and higher NH3-N.
In order to further oxidize and decompose organic matter, and at the same time, nitrification can proceed smoothly when carbonization is completed, an aerobic biological contact oxidation pool with a lower organic load is set at Class O. In the O-class pool, there are mainly aerobic microorganisms and autogenous bacteria (nitrifying bacteria). Aerobic microorganisms decompose organic matter into CO2 and H2O; autogenous bacteria (nitrifying bacteria) use inorganic carbon produced by the decomposition of organic matter or CO2 in the air as a nutrient source to convert NH3-N in sewage into NO2-NNO3-N. The effluent of the O-class pool flows back to the A-class pool, providing electron acceptors for the A-class pool, and ultimately eliminating nitrogen pollution through denitrification.

★Main features

HTM-AO series integrated sewage treatment equipment can be buried below the surface, and the surface can be used as greening or square land. Therefore, the equipment does not occupy the surface area, does not need to build a house, and does not need heating and insulation.
HTM-AO series integrated sewage treatment equipment consists of two-stage pools, one of which is a reinforced concrete structure with a large burial depth, and the other is a steel structure with a shallow burial depth. The steel structure pool is protected by an interpenetrating network anti-corrosion coating. It is an interpenetrating network polymer formed by the mutual penetration of a rubber network and a plastic network. It is resistant to acid, alkali, salt, gasoline, kerosene, aging, and abrasion. After the equipment is generally painted with this coating, the anti-corrosion life can reach more than 12 years.
The AO biological treatment process in the HTM-AO series integrated sewage treatment equipment adopts a plug-flow biological contact oxidation tank, and its treatment effect is better than that of a completely mixed or two- and three-stage series completely mixed biological contact oxidation tank. And it is smaller in size than the activated sludge tank, has strong adaptability to water quality, good impact resistance, stable effluent water quality, and will not produce sludge expansion. At the same time, a new type of elastic three-dimensional filler is used in the biological contact oxidation tank. It has a large actual specific surface area, microbial film, and easy demoulding. Under the same organic load conditions, it has a higher removal rate of organic matter than other fillers, and can increase the solubility of oxygen in the air in water.
Because the biological contact oxidation tank is used in the AO biological treatment process, the volume load of its filler is relatively low, and the microorganisms are in the self-oxidation stage, so the sludge production is relatively small. In addition, the water content of the sludge produced by the biological contact oxidation tank is much lower than that of the sludge produced by the activated sludge tank. Therefore, the amount of sludge produced after the sewage is treated by the sewage treatment equipment is relatively small, and it generally takes about 90 days to discharge the sludge.
In addition to the conventional blower silencing measures (such as vibration isolation pads, silencers, etc.), the HTM-AO series integrated sewage treatment equipment also sets a new sound-absorbing material on the inner wall of the blower room, so that the noise during the operation of the equipment is less than 50 decibels, reducing the impact on the surrounding environment.
The HTM-AO series integrated sewage treatment equipment is equipped with soil deodorization facilities. It uses the upper space of the reinforced concrete structure tank body to set improved soil and air distribution pipes. When the odorous components pass through the soil layer and dissolve in the water contained in the soil, they are then transferred into the soil due to the surface adsorption and chemical reaction of the soil, and finally decomposed by the microorganisms in the soil to achieve the purpose of deodorization.
The HTM-AO series integrated sewage treatment equipment is equipped with an automatic electrical control system and an equipment damage alarm system. The equipment has good reliability, so it generally does not require special management, and only requires monthly or quarterly maintenance.

★FAQ

Q. What are the common sewage treatment processes?
A. Common sewage treatment processes include activated sludge method (such as A²/O, oxidation ditch, SBR), biofilm method (such as biofilter, biorotor), membrane bioreactor (MBR), etc. These processes mainly use physical, biological and chemical means to remove organic matter, suspended solids, nitrogen and phosphorus and other pollutants in sewage to achieve standard discharge or water resource reuse.

Q. How is the sludge generated during sewage treatment handled?
A. The sludge generated during sewage treatment needs to be concentrated, dehydrated, stabilized (such as anaerobic digestion) and other treatments to reduce the volume and reduce pollution. The treated sludge can be used as a resource, such as fertilizer, incinerated for power generation, or landfilled. Reasonable disposal of sludge is an important part of ensuring that the entire sewage treatment process meets environmental standards.

Q. Does the sewage treatment plant have a bad smell? How to control the odor pollution?
A. Sewage treatment plants may produce bad smells at water inlets, grit chambers, sludge treatment areas and other places. In order to control the odor pollution, deodorization measures such as sealing facilities, negative pressure collection, chemical washing, biological filters or activated carbon adsorption are usually adopted, and the plant area is reasonably laid out and green belts are set up to reduce the impact on the surrounding environment.
