In the current context, wastewater treatment has become a critical factor for protecting water sources and human living environments. Companies that fail to properly manage this process may face legal penalties or, worse, be prohibited from operating. To understand in detail how to achieve standard industrial wastewater treatment systems, let's explore with Môi Trường Đại Nam.**
1. Industrial Wastewater Treatment Systems
The construction of a compliant industrial wastewater treatment system depends on the following factors:
- Treatment Plant Capacity: The system must be designed to handle the expected volume of wastewater.
- Post-Treatment Water Quality: Ensuring the treated water meets required quality standards.
- Characteristics of Wastewate: The composition and nature of the wastewater from industrial activities.
- Discharge Regulations: Compliance with regulations for discharging into public sewers or water bodies.
- Treatment Efficiency: The effectiveness of the treatment process.
- Available Land Area: The space available in the industrial area for system installation.
- Future Expansion: Consideration of the industrial area's growth and development trends.
- Energy and Chemical Requirements: Availability of energy, chemicals, and equipment on the market.
- Technology Safety: Ensuring high safety standards for variations in flow rates and pollutant concentrations between rainy and dry seasons.
- Simplicity and Cost: The system should be easy to operate, stable, and cost-effective.
2. Standard Industrial Wastewater Treatment Technologies
2.1 Pre-Treatment
- Removal of Large Debris: Eliminating trash and coarse solids larger than 10 mm.
- Removal of Surfactants and Oils: Separating surface-active substances and oils.
- Balancing Concentration and Flow: Equalizing the concentration and flow rates of the wastewater.
2.2 Biological Treatment Technology
- Anaerobic UASB Technology**: Uses Upflow Anaerobic Sludge Blanket (UASB) technology to reduce complex organic compounds into simpler substances, thereby lowering BOD and COD levels. This method is suitable for wastewater with very high organic content (up to thousands of mg/l). The process involves various microorganisms and produces gases such as CH4, H2S, H2, CO2, and NH3.
- Aerobic Aerotank Technology**: Employs Activated Sludge Process (Aerotank) to convert organic matter into CO2 and H2O, reducing BOD, COD, and SS. This aerobic process relies on aerobic microorganisms, particularly bacteria, that use dissolved oxygen to decompose organic matter. Specific microorganisms like *Pseudomonas Denitrificans* and *Bacillus Licheniforms* convert nitrate to N2, and excess nitrogen and phosphorus are removed.
2.3 Final Treatment
- Disinfection and Pressure Filtration: Ensures the treated water is free from pathogenic microorganisms and residual solids before discharge into receiving water bodies.
2.4 Sludge Management
- Sludge Dewatering: Sludge is dewatered in sludge presses and then transported by specialized trucks for disposal or dried using belt presses.
The basic industrial wastewater treatment system is as described above. However, depending on the characteristics of the wastewater from different industries, the scale, and specific requirements of each company, the system may vary.
