Sewage treatment project of sewage treatment plant

Sewage treatment project of sewage treatment plantThis device is suitable for burial underground, does not occupy surface area, and operates without affecting the surrounding area. It is also applicable to organic industrial wastewater and domestic wastewater similar to domestic wastewater in industries such as food, slaughter, brewing, printing and dyeing. The equipment can be fully buried, partially buried, or placed on top of the ground, arranged in different standard forms, and can be set according to terrain needs; When the equipment is buried underground, it basically does not occupy the surface, and the upper part can be used as green space, pedestrian walkway, etc. It has no impact on the surrounding area during operation. The filling material in the contact oxidation tank is a combination filling material, which is lightweight, high-strength, physically and chemically stable, has a large specific surface area, strong biological adhesion ability, and high contact efficiency between sewage and biofilm; The entire equipment processing system is equipped with a fully automatic PLC electrical control system and equipment fault alarm system, which operates safely and reliably. There is no need for dedicated personnel to manage it, only timely maintenance and upkeep of the equipment is required.

Sewage treatment project of sewage treatment plantThe processes for treating domestic sewage include anaerobic filters, jet aeration, contact oxidation, oxidation ponds, and subsurface flow constructed wetlands.

The principle of anaerobic filtration process is to fix a large number of anaerobic microorganisms on the packing of the filter, and use the degradation effect of anaerobic microorganisms to decompose organic matter into gases such as methane and carbon dioxide, achieving purification.

SBR process

Contact oxidation process, also known as "submerged biological filter", "contact aeration method", "fixed activated sludge method", is a sewage treatment technology that was pioneered in the early 1970s. Its technical essence is to fill the biological reaction tank with fillers, and the already oxygenated sewage submerges all the fillers and flows through them at a certain flow rate. Covering the packing with biofilm, sewage comes into extensive contact with the biofilm. Under the metabolism of microorganisms on the biofilm, organic pollutants in the sewage are removed and purified.

Contact oxidation process

The biological contact oxidation method combines the characteristics of activated sludge method and biofilm method. The concentration of biological solids in the tank (5-10g/l) is higher than that of activated sludge method and biofilter, and has a higher volumetric load (up to 2.0-3.0kgBOD5/m3. d). In addition, the contact oxidation process does not require sludge reflux, has no sludge expansion problem, and is simpler to operate and manage than activated sludge method. It has strong adaptability to fluctuations in water quantity and quality. It is a typical aerobic treatment method with the advantages of high aeration rate, high treatment degree, and automated control.
