400m³ gas holder for industrial wastewater  

Project Address: Ningbo City, Zhejiang Province

At an industrial wastewater treatment project site in Ningbo, Zhejiang Province, a 400m³ double-membrane gas holder is being steadily constructed and put into operation, serving as a key and indispensable unit within the overall wastewater treatment system. The project mainly supports the anaerobic treatment process for industrial wastewater, providing safe, stable, and efficient storage and regulation of biogas generated during treatment, thereby ensuring reliable conditions for subsequent energy utilization.

The project is equipped with a 400 m³ gas holder featuring a double-membrane structural design, offering excellent gas tightness and corrosion resistance. It is well suited to the complex composition of industrial wastewater and the significant fluctuations in biogas production. Through an automatic control system, the gas holder regulates internal pressure in real time, effectively balancing biogas generation and consumption. This ensures stable operation of the anaerobic system, significantly reduces the risk of biogas leakage, and enhances overall operational safety.

At the construction site, the project has been implemented in strict accordance with design specifications and construction standards. From foundation works and installation of embedded parts to erection and commissioning of the gas holder, all construction stages are closely coordinated and well organized. Taking into account the local climate and environmental conditions of Ningbo, targeted measures have been adopted in terms of corrosion protection, wind resistance, and rain protection to ensure long-term and reliable equipment operation.

The implementation of this 400 m³ industrial wastewater gas holder project not only improves the reliability of the wastewater treatment system but also enables centralized management and efficient utilization of biogas resources. It provides strong support for energy conservation, emission reduction, and green development in industrial parks. After commissioning, the project will play a positive role in improving environmental quality, reducing operating costs, and promoting the transformation of industrial wastewater treatment toward resource recovery and energy utilization.
