Our introduction to the compact integrated wastewater treatment equipment, commonly known as the AAO process, which stands for Anaerobic-Anoxic-Oxic biological nitrogen and phosphorus removal technology. This process generally achieves a treatment efficiency of: BOD5 and SS up to 90%-95%, total nitrogen above 70%, and phosphorus around 90%.

The compact integrated wastewater treatment equipment features physical filtration, biological degradation, and plant interception processes, effectively removing organic matter while, through the collaboration of aquatic plants and microorganisms, achieving the removal of N and P. It is particularly suitable for projects involving the treatment and reuse of rural domestic wastewater, river, and natural lake water systems.

The centralized wastewater treatment system boasts high automation and ease of management, ensuring excellent effluent quality and high stability. In light of the current rural wastewater situation, it fully meets national discharge requirements. Currently, there are numerous engineering examples of various centralized wastewater treatment methods in China, with extensive experience accumulated in construction and management, excluding land treatment methods.
