Solar powered high-efficiency aeration tower
Equipment Description
As is well known, oxygen is one of the important conditions for aerobic treatment, and the energy consumption of oxygenation is an important component of the operating cost of sewage treatment. The traditional contact oxidation method mainly utilizes aeration and oxygenation equipment for oxygenation. This device uses drop water oxygenation technology to provide the oxygen demand for aerobic reactions. The contact tank is operated in series with multiple tanks, and the sewage is lifted once by a micro sewage lift pump. The height difference between tanks is utilized to gradually drop water. Each tank is set with a different drop water height, and one or multiple baffles are installed at the drop water height to improve the dispersion of sewage and the time of contact with air, so that water can be oxygenated by contact with air during the drop process. Due to the use of drop water as the oxygenation method, only the sewage needs to be lifted into the drop water oxygenation contact oxidation tank, saving the power consumption of the blower required for aeration. The micro sewage lift pump is powered by solar energy, greatly reducing the consumption of electricity and effectively reducing the impact on air. By reducing operating costs and simplifying facility maintenance and management, it is suitable for the requirements of rural domestic sewage treatment.

Performance characteristics
1. By combining multi-stage perforation water drop and horizontal overflow natural oxygenation, the dissolved oxygen concentration of the sewage after oxygenation is maintained above 2.0mg/L. This not only ensures the effectiveness of sewage treatment, but also reduces the energy consumption required for aeration in the aerobic tank, greatly reducing operating costs and simplifying facility maintenance and management.
2. Fully utilizing natural energy, all the electricity required for power is provided by solar energy systems, saving energy.
3. A flat dynamic membrane is installed in the contact oxidation tank at all levels to ensure the concentration of sludge in the tank, while improving the solid-liquid separation effect and reducing the load of subsequent treatment.
4. Set up as a circular tower structure, combining sewage treatment with environmental beautification construction, beautiful and practical.
Parameter
The aeration tower is evenly distributed in a circular shape with 6 drop water aeration systems. Each drop water aeration system is divided into 5 stages, with each stage measuring 1 × 0.5 × 0.3m and occupying an area of approximately 28 m2. All the electrical energy required for the lift pump is provided by the solar energy system, which consists of 10 solar panels (each measuring 670 × 1500mm) and 4 solar cells (each measuring 200AH) per 5m3/h and can handle water volumes of 10m3/h or less
