Introduction of domestic sewage treatment equipment

Treatment equipment of domestic sewage is concentrated equipment of missing oxygen tank, hydrophobicity tank, playtank, slurry tank, sterilization tank, etc. Domestic sewage treatment equipment is an integrated treatment device that is specially designed for residential areas, small and medium businesses or rural areas, designed for cleaning waste water created in everyday life. These equipment usually include several important steps such as pre-treatment, biological treatment, chroma and sterilization. They can effectively remove suspended substances, organic substances and antimicrobial creatures from sewage water and ensure that the waste water quality is in accordance with the relevant standards.

 
Domestic sewage treatment equipment component

The component of domestic sewage treatment equipment includes various components and treatment units. The active sewage treatment equipment is mainly including grille adjustable tank unit, A2O unit, BAF unit and UV sterilizing unit.
Mesh adjusting tank unit: storage net well, adjusting tank.
A2O unit: hydrophobicity tank, oxygen tank, bubble tank, sedimentation tank.
BAF unit: including BAF group.
UV germicidal unit: UV germicidal device is included.
Regular sewage treatment system related to integrated sewage treatment equipment, air floating machine, centrifugal machine, aerator, micro purifier, mechanical grille removal machine, UASB hydrophobicity reactor, IC reactor, Metering Equipment, chlorine dioxide generator, etc, as well as parts like waste water heat exchanger and waste water source heat pump. The components work together to complete the efficient domestic sewage treatment and ensure that the water quality meets the discharge or reuse standards.

 
Features of domestic sewage treatment equipment

The features of domestic sewage treatment equipment mainly include:
1. smaller size than normal activated mud, strong response to water quality, impact strength, stable water quality output and will not produce mud expansion. New stereo elastic filler materials used in the swimming pool, the specific surface area is bigger, the bacteria is easy to hang the film and remover. In the same organic load condition, the high rate of removing organic substances, can improve the solubility of oxygen in water.
2. The whole processing system equipped with full automatic electric control system and equipment error alarm, safe and reliable operation, generally no special management is required, just check, maintain and maintain the equipment in time.
3. appliances can be put on the ground and buried on the ground. When buried under ground, the upper cover can be used to solidify, the factory area has small area and small ground structure.

The sewage treatment plant (STP) uses the "A2O+BAF+UV+sterilization" process.

The A2O process, which stands the English stands for anameric anoxic oxic, is done to destroy nitrogen and destroy phosphate by the use of hydrophilic creatures-oxygen-deficient. In the A2O, BOD5, SS and nitrogen and phosphate process in various forms will be removed one by one. In the hydrophobicity and oxygen shortage segments, the plant system is mainly composed of nitrifying bacteria and polyphospourus, and in the iceelement, the phytochemicals are mainly composed of nitrifying bacteria and polyphosporus.

BAF means aerated biological filter tank is the biofilm treatment process that coexist with solid three-phase, liquid and gas, belongs to the technology of sewage biotreatment combined with oxidation and contact purification, Its core technology is the application of foam purification material and the use it as a biological carrier for waste water treatment. A cloth water system set on the top of the BAF tank, it can evenly distributes waste water to the surface of filtration materials, so that drip water can be fully contact with oxygen. Micro-creatures on the surface of the filter material by deforming-and then re-sticking, finally formed a stable biological membrane, will not proceed with an explanation. Because of the pant and oxygen shortage caused in the membrane, there is high operation, the softener can successfully remove the contaminants once it melts through the biological membrane.

Ultraviolet sterilization is through ultraviolet light radiation, destroy and change the DNA structure of the bacteria (deoxyride acid), make bacteria die immediately or unable to produce children, in order to achieve the purpose of germicidal bacteria.
