Let's first understand the small-scale integrated wastewater treatment equipment, which generally employs the AAO process, a shorthand for Anaerobic-Anoxic-Oxic biological nitrogen and phosphorus removal process. This process typically achieves treatment efficiency of: BOD5 and SS at 90% to 95%, total nitrogen above 70%, and phosphorus around 90%.

Our compact integrated wastewater treatment equipment features physical filtration, biological degradation, and plant interception processes, effectively removing organic matter while collaborating with aquatic plants and microorganisms to eliminate nitrogen and phosphorus. It is particularly suitable for rural domestic wastewater treatment, river and natural lake water system treatment, and recycling projects.

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.
