Sewage Treatment

Technical Background

The 2024 No.1 Central Document, "Opinions of the CPC Central Committee and the State Council on Studying and Utilizing the Experience in the Green Rural Revival Program and Vigorously and Effectively Promoting Comprehensive Rural Revitalization", emphasizes the continued battle against agricultural and rural pollution and the strengthening of rural ecological civilization construction. It calls for the promotion of domestic wastewater treatment in a phased manner tailored to local conditions. Currently, China's rural domestic wastewater treatment lacks unified planning and management, with treatment facilities facing issues of unstable operation and poor effectiveness, sometimes even causing secondary pollution. Therefore, there is an urgent need to improve rural wastewater treatment technologies to enhance treatment efficiency.

Technical Introduction

The solution adopts self-developed cyclic aeration filter (CAF) to optimize the traditional Anaerobic-anoxic-aerobic method (AAO) process, allowing microorganisms to attach to the filler surface in large quantities. This effectively saves space and increases treatment efficiency, ensuring that effluent water quality consistently meets relevant rural wastewater discharge standards.

Technical Advantages

High treatment efficiency

The high-density filler with a large specific surface area increases treatment efficiency by more than 10% compared to traditional processes.
Reduced sludge production

The amount of sludge produced is reduced by 70% compared to traditional processes, with the majority being inorganic sludge.
Space-saving

The technology increases treatment efficiency and reduces the footprint for the biochemical section.
Stable effluent quality

The process design is reasonable, and the effluent quality consistently meets Class A standards.
