Industrial wastewater treatment
Industrial wastewater treatment is a top concern in a rapidly developing urban society with industrial parks constantly being built and expanded today.
When industrial parks are built, the amount of waste produced during the production process increases, which means that environmental pollution increases. Therefore, when constructing business facilities, the issue of industrial wastewater treatment is always of interest and attention to businesses, building industrial wastewater treatment systems as well as appropriate industrial wastewater treatment methods. Each type of industry has its own characteristics in terms of composition, pollution load, and different levels of toxicity, so industrial wastewater treatment is applied differently to ensure the best treatment capacity, not causing environmental pollution, and ensuring wastewater treatment standards according to the provisions of law.
Industrial wastewater treatment methods:
Mechanical treatment method: This is a method that uses structures such as trash racks, oil and grease traps, equalization tanks, and settling tanks.
Physicochemical treatment method: This is a wastewater treatment method that applies physical and chemical processes to remove pollutants, including coagulation and flocculation tanks; flocculation tanks or absorption structures.
Chemical treatment method: Wastewater treatment by chemical methods is a measure that brings high quality and perfect efficiency to wastewater treatment.
Biological treatment method: This is an industrial wastewater treatment method based on the oxidation of organic substances in wastewater by dissolved free oxygen or the treatment process is carried out by the decomposition of organic substances.
Industrial wastewater treatment technology
Industrial wastewater treatment technology explanation
Wastewater from factories follows the sewer system to the collection pit, before entering the collection pit, the wastewater flows through a trash rack to remove large trash. Then, the wastewater is pumped through a fine screen to remove smaller solids.
After passing through the screen, the water will flow into the equalization tank. Here, the water flow and quality will be stabilized thanks to the aeration process. Then, the wastewater is pumped to the coagulation - flocculation and physical sedimentation tank. After the sedimentation process in the physical and chemical sedimentation tank, the wastewater overflows the tank to the anoxic tank. Here, the wastewater is mixed with microorganisms (recirculating water and sludge), in an anaerobic environment, microorganisms will remove nitrogen compounds. Next, the wastewater flows through the AFBR biological tank. Here, the mixture of water and sludge is supplied with oxygen, aerobic microorganisms will use organic matter for growth. Water from the aerotank flows through settling tank 2, then disinfects in the contact tank with NaOCl and is then pumped by a high-pressure pump through a pressure filter column to remove any remaining suspended solids in the wastewater. Finally, the wastewater is discharged to the receiving source.
Sludge from settling tank 1 and settling tank 2 is fed into an aerobic sludge digester to decompose the remaining organic matter (reduce sludge volume) and then through a belt filter to remove water (reduce sludge moisture) and discharge. Water from the sludge digester and sludge press returns to the equalization tank for reprocessing.
