How does the Integrated Domestic Sewage Treatment Plant utilize advanced biological treatment technology to improve the removal efficiency of organic pollutants?
2026/07/21
With increasing urban construction, industrial development, and stringent environmental protection requirements, wastewater treatment systems not only need stable treatment capacity but also must be energy-efficient, highly efficient, and intelligently operated. Traditional wastewater treatment facilities generally suffer from large footprints, long construction periods, and complex operation and maintenance, making it difficult to meet the demands of modern decentralized wastewater treatment and rapid construction. The Integrated Domestic Sewage Treatment Plant adopts an integrated modular design, integrating pretreatment, biodegradation, sedimentation, disinfection, and sludge treatment into a single system. Combined with advanced biological treatment technology, it significantly improves the removal efficiency of organic pollutants, providing a more efficient and stable solution for municipal, industrial, and rural wastewater treatment.
Advanced Biological Treatment Technology Achieves Highly Efficient Organic Degradation
The core advantage of the Integrated Domestic Sewage Treatment Plant lies in its advanced biological treatment system. The equipment can employ various mature processes, such as AO, MBBR (Moving Bed Biofilm Reactor), or MBR (Membrane Bioreactor), depending on different project requirements. Through the synergistic action of anaerobic and aerobic bacteria, it continuously decomposes organic pollutants such as COD and BOD in wastewater.
After pretreatment, the wastewater enters the biological reaction zone. Anaerobic microorganisms first break down complex macromolecular organic matter into smaller, more easily degradable molecules. Then, aerobic microorganisms continue to oxidize and decompose these substances into carbon dioxide and water, significantly improving pollutant removal efficiency. The entire process operates continuously and stably, ensuring the system maintains high treatment efficiency even in the face of water quality fluctuations, creating favorable conditions for subsequent deep purification.
Multi-stage synergistic process ensures continuous and stable treatment results.
To further enhance overall purification capacity, the Integrated Domestic Sewage Treatment Plant employs a multi-stage synergistic treatment mode, with each treatment unit closely integrated to achieve stable and efficient operation.
In the pretreatment stage, large particulate impurities are removed through screens, grit removal, and oil separation, reducing the load on subsequent equipment. After biological treatment, the wastewater enters the sedimentation system to separate activated sludge from the purified water. A portion of the sludge is returned to the biological reaction zone to maintain microbial activity, while the remaining sludge undergoes concentration and dewatering. Finally, combined with ultraviolet or ozone disinfection and deep filtration, pathogens and residual suspended solids are effectively removed, ensuring the treated effluent meets discharge or reuse standards. The overall COD and BOD removal rates can reach approximately 95%.
Intelligent Control Enhances System Efficiency
In addition to advanced treatment processes, the Integrated Domestic Sewage Treatment Plant is equipped with a PLC intelligent control system and an IoT remote monitoring platform to automatically adjust parameters such as aeration, sludge return, influent and effluent flow, and water quality changes.
The system can automatically optimize aeration intensity and operating modes based on wastewater flow and pollutant concentration, ensuring that microorganisms are always in optimal working condition while effectively reducing energy consumption. Simultaneously, the equipment supports automatic alarms, remote monitoring, and data analysis, significantly reducing the frequency of manual inspections, achieving long-term stable operation, and improving overall operational efficiency and management level.
Modular Design Meets Multiple Wastewater Treatment Needs
The Integrated Domestic Sewage Treatment Plant adopts a prefabricated modular structure, integrating multiple treatment processes into a compact unit. It occupies a much smaller area than traditional wastewater treatment plants and eliminates the need for large-scale civil engineering construction, enabling rapid transportation, installation, and commissioning.
