A2/O Process
Containerized Sewage Treatment Equipment adopts A2/O process, which ensures the removal effect of COD, ammonia nitrogen, total nitrogen and also strengthens the removal effect of phosphorus.Containerized Sewage Treatment Equipmentadopts biofilm process, where microorganisms mainly grow on spherical fillers, which can achieve the separation of hydraulic retention time and sludge retention time, and help to enrich the specialized functional microorganisms which have a long generation time and a good treatment effect, and the biofilm is microbial aggregation with certain thickness, and compared with activated sludge method, biofilm method is more resistant to shock load and the operation of the equipment is more stable. Containerized Sewage Treatment Equipment adopts the design concept of low volumetric loading, and the hydraulic retention time is more than 24 hours, which helps to increase the microbial self-oxidizing ability, and improves the quality of the effluent while reducing the production of residual sludge, and reduces the cost of sludge treatment and the cost of construction of sludge tanks. SMC sewage treatment tank is simple and unmanned operation, the use of Internet of Things technology can realize remote mobile management to save operation and maintenance labor costs. 

                                                                  A²O Process Schematic Diagram
(1) Anaerobic, anoxic, and aerobic, the combination of three different environmental conditions and microbial communities are capable of simultaneously removing organic matter and nitrogen and phosphorus. 
(2) In the process of simultaneous deoxygenation, phosphorus removal, and organic matter removal, this process flow is the simplest, and the total hydraulic retention time is also less than other similar processes. 
(3) Under the alternating environmental of anaerobic, anoxic and aerobic, filamentous bacteria do not reproduce in large numbers, and the SVI is generally less than 100, so sludge expansion does not occur. 
(4) The phosphorus content in sludge is high, generally above 2.5%.

Process description
1.  After passing through the septic tank, the sewage from each household is collected by the sewage pipe network. The animal and vegetable oil in the sewage must be removed by a grease trap before entering the sewage pipe network for treatment.
2. After the domestic sewage is collected in the pipeline network, the debris and large particles are separated through the bar screen well to prevent blockage.
3. After separated by the bar screen well the sewage enters into the equalization tank. The purpose to set up equalization tank is to control water quality and water quantity to meet process requirements, so that the water quality and water quantity entering the treatment tank are more stable.
4. The sewage in the equalization tank is pumped to the treatment tank for treatment through a  lifting pump.
5. The intelligent sewage treatment tank is designed with five compartments, they are: oil separation and sand sedimentation compartment, anaerobic compartment, anoxic compartment, aerobic compartment and sedimentation compartment. It degrades COD in sewage through the action of microorganisms and realizes denitrification at the same time. 
6. After being treated by the intelligent sewage treatment tank, the sewage enters the ecological filter for polished treatment. The sewage is deeply treated by the synergistic effects of artificial media, plants, and microorganisms, ensuring that the sewage is stably discharged in compliance with the standards. The effluent from the ecological filter flows into the nearby water body.
7. The intelligent sewage treatment tank is made of SMC/Glass fiber reinforced plastic material, we provide 1 year warranty for the whole system.

BG Functional Microorganisms
BG functional microorganisms are special functional microorganisms developed for pollutants such as nitrogen, phosphorus, and oil in water bodies. They have significant phosphorus and nitrogen removal effects and have been widely used in many places.
The BG series functional microorganisms mainly include denitrifying microorganisms, polyphosphate accumulating microorganisms, oil removing microorganisms, and various COD reducing microorganisms. The main strains of microorganisms come from the environment itself. Take from the environment and use for the environment.     

Agents	Name of Strain	Applications
BG denitrifying compound microbial agent	Composed of various efficient water purification functional microorganisms  such as ammonia oxidizing microorganisms, nitrifying microorganisms, photosynthetic microorganisms, denitrifying microorganisms, etc., it can remove nitrogen from water bodies	Ecological restoration and reconstruction of eutrophic water bodies such as polluted rivers, lakes, and reservoirs, treatment of domestic sewage, and treatment of nitrogen-containing wastewater
BG polyphosphate compound microbial agent	Mainly composed of polyphosphate accumulating microorganisms, it removes phosphorus from water bodies	Ecological restoration and reconstruction of eutrophic water bodies such as polluted rivers, lakes, and reservoirs, treatment of domestic sewage, and treatment of nitrogen-containing wastewater
BG oil removal compound microbial agent	Degreasing microorganisms	Ecological restoration and reconstruction of eutrophic water bodies such as rural tourism wastewater, oily wastewater, polluted rivers, lakes, reservoirs, etc
BG black and odorous removal compound  microbial agent	Photosynthetic microorganisms, Bacillus subtilis, yeast, lactic acid microorganisms, coagulants, EM decolorizing microorganisms, cellulose degrading microorganisms, polycyclic aromatic hydrocarbon degrading microorganisms	Ecological restoration and reconstruction of eutrophic water bodies such as polluted rivers, lakes, and reservoirs.

This strains has the following characteristics:
1. High treatment efficiency and high treatment flux: the treatment capacity per unit tank capacity reaches 2-3 times that of the "activated sludge method";
2. Extremely low sludge production: The unit sewage sludge production is only about 30% of that of the "activated sludge method";
3. Strong ability to remove total nitrogen and phosphorus;
4. Good sludge settling performance and good effluent effect;

Product Features

1. Easy to install: the equipment can be buried underground, and the surface can be used
as green space or square land. It does not occupy any surface area, does not need to build a house, and does not require
heating and insulation.
2. Low operation and maintenance costs: low equipment operation and maintenance costs
3. Emissions meet standards: The technology is mature and emissions meet standards.
4. High degree of automation: the equipment can realize fully automatic operation
according to the set operating parameters.
5. Stable operation: The equipment operates stably and has a low failure rate.
