Product introduction
Introduction to sewage treatment plant (STP)
The sewage treatment plant (STP) is a comprehensive water treatment device, which integrates the functions of anoxic tank, anaerobic tank, aerobic tank, sedimentation tank, sludge tank and disinfection tank. This system is tailored for residential communities, small and medium-sized enterprises or rural areas to efficiently clean domestic wastewater. It covers key steps such as pre-treatment, biological treatment, sedimentation and disinfection to effectively remove suspended solids, organic matter and pathogens in sewage and ensure that the water quality after treatment meets environmental requirements.
Sewage treatment plant (STP) composition
The sewage treatment plant (STP) consists of a variety of different components and units, including the grid conditioning cell unit, the A2O unit, the BAF unit and the UV disinfection unit. These units are responsible for initial filtration, water balancing, multi-stage biochemical treatment and final disinfection. In addition, the system may contain equipment such as air floats, centrifuges, aerators, as well as various reactors and dosing systems, which work together to achieve a complete purification of the wastewater.
Characteristics of sewage treatment plant (STP)
Features of sewage treatment plant (STP) include:
1. Small size, adapt to different water quality environment, strong load impact resistance, maintain stable effluent quality, avoid sludge swelling problem.
2. Use new materials to enhance the treatment efficiency of microorganisms, improve the solubility of oxygen in water, and optimize the treatment effect of organic pollutants.
3. Equipped with automatic control system and fault alarm mechanism to ensure safe operation and simple maintenance of equipment, reducing manpower requirements.
4. The structure design is flexible, and the ground installation or underground layout can be selected according to the actual situation. The buried type helps to save space and greening.
In summary, sewage treatment plant (STP) is an indispensable environmental protection facility in the process of modern urbanization, which not only ensures the effective use of water resources, but also helps to maintain ecological balance and environmental health.
Technical principle of
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.
