The integrated sewage treatment equipment is mainly suitable for residential areas, rural towns, highway service areas, hotels, restaurants, hospital clinics, nursing homes, universities, large shopping malls, ship ports, subway stations, airports, factories and mining enterprises, tourist attractions, villa buildings, scenic spots and other domestic sewage or various industrial production organic chemical wastewater that is similar to domestic sewage treatment. The key solution is to use the relatively complete biochemical solution technology - microbial contact air oxidation method. The main parameters of the water body design scheme are calculated according to the main parameters of general domestic sewage treatment water bodies, and the BOD5 design scheme is based on 200mg/L. Fully automatic equipment can be installed underground, so it is also known as "buried integrated MBR sewage treatment equipment".

*Biological pool (anoxic pool):

Further mixing the sewage and fully utilizing the efficient bio elastic packing material in the pool as a bacterial carrier, the difficult to dissolve organic matter in the sewage is converted into soluble organic matter by facultative microorganisms, and the large molecular organic matter is hydrolyzed into small molecular organic matter, which is conducive to further oxidation and decomposition in the O-grade biological treatment tank. At the same time, the refluxed nitrate nitrogen can undergo partial nitrification and denitrification under the action of nitrifying bacteria to remove ammonia nitrogen.

O-level biological tank (biological contact oxidation tank):

This pool is the core part of this sewage treatment, divided into two sections. In the first section, under high organic load, a large number of microbial communities of different species attached to the packing participate in biochemical degradation and adsorption, removing various organic substances from the sewage and significantly reducing the organic content in the sewage; In the latter stage, under the condition of reduced organic load, the action of nitrifying bacteria degrades ammonia nitrogen in the sewage under sufficient oxygen conditions, while also reducing the COD value in the sewage to a lower level, thus purifying the sewage. The two-stage design can degrade water quality into gradients, achieving good treatment effects. At the same time, the design adopts corresponding diversion and turbulence measures to make the design more reasonable.

The aeration method adopts microporous aeration, which can effectively avoid pipeline blockage caused by sludge generated during wastewater treatment, prolong the service life, and improve oxygen utilization efficiency.

Sedimentation tank:

Precipitation is the process by which suspended solids in wastewater separate from water under the influence of gravity. This process is simple and easy to implement, with good separation effect, and is often one of the most common processes in various sewage treatment systems. The function of the sedimentation tank here is to perform solid-liquid separation and remove the biofilm and suspended sludge peeled off from the biochemical tank, so as to truly purify the sewage and stabilize the effluent effect.

Disinfection pool:

The effluent from the secondary sedimentation tank flows into the disinfection tank for disinfection, ensuring that the effluent quality meets the hygiene requirements and is discharged as qualified. Design a disinfection device, guide plate, and disinfection design in the disinfection pool using a chlorine contact method. This dosing method has the characteristics of convenient dosing, simplicity, and safety. After disinfection, the water is discharged into the municipal sewage pipeline or nearby water areas.

Sludge tank:

The sludge from the secondary sedimentation tank is regularly discharged into the sludge tank through a sludge pump, and a sludge return device is installed. Some of the sludge is returned to the biological treatment tank for nitrification and denitrification, which not only reduces the generation of sludge but also facilitates the removal of ammonia nitrogen from the sewage. The remaining sludge is subjected to sludge concentration, aerobic digestion, and the supernatant of the sludge is discharged back into the regulating tank for further treatment. The remaining sludge is regularly pumped out (two to three times a year).

清水池：

The effluent from the disinfection tank enters the clean water tank and can be discharged directly to meet the standard or reused as reclaimed water.

Process flow description:

Wastewater is intercepted by a grid to remove solid suspended solids such as waste residue, paper scraps, and fibers from the water. It enters a regulating tank, where it is homogenized and evenly distributed before being pumped to a biological tank. In the biological tank section, heterotrophic bacteria hydrolyze soluble organic matter into organic acids, decomposing large organic matter into small organic matter and insoluble organic matter into soluble organic matter. Pollutants such as proteins and fats are ammoniated.

There are aerobic microorganisms and digestive bacteria in the O-level biological pool section, where aerobic microorganisms decompose organic matter into CO2 and H2O; Under sufficient oxygen supply conditions, the nitrification process of nitrifying bacteria oxidizes NH3-N to NO3-, which is then returned to the biological tank through reflux control. Under anaerobic conditions, the denitrification process of anaerobic bacteria reduces NO3- to molecular nitrogen. The effluent from the contact oxidation tank flows automatically into the sedimentation tank for precipitation, and the effluent from the sedimentation tank enters the disinfection tank for chlorine dioxide disinfection. The disinfected effluent meets the discharge standards. Part of the sludge in the sludge tank is returned to the biological tank, and the remaining sludge is regularly transported for disposal.
