20m3 Sewage Treatment Plant Project Capacity 50000 Tons

Sichuan Chengdu sewage treatment plant project, with a daily sewage treatment capacity of 50,000 tons

When you walk into the Sichuan Chengdu Sewage Treatment Plant project, you will see unique storage tanks. These storage tanks are covered with artistic "painted new clothes", with majestic mountain scenery, profound historical allusions, and lively panda images, which complement the surrounding environment and help improve the quality of Chengdu's city.


The Sichuan Chengdu sewage treatment plant project is one of the larger sewage treatment plant projects that Shijiazhuang Zhengzhong Technology Co., Ltd. participated in. The company focuses on customer needs and provides customized solutions. It uses independently developed and produced enamel assembled tanks and carbon steel spliced tanks as sewage treatment equipment, with a daily treatment capacity of 50,000 tons. The construction of this project will effectively meet the urgent municipal sewage treatment needs for local development, improve urban sewage treatment capacity, reduce net pollutant emissions, greatly improve the level of urban infrastructure, and further strengthen the protection of Chengdu's water resources.

Advantages of enamel assembled tanks
Superior anti-corrosion technology
Center Enamel independently develops double-sided double-layer enamel technology to fill the gap in the Chinese enamel industry in the field of hot-rolled double-sided enamel technology. This technology is currently the best coating anti-corrosion technology in the steel storage tank market and has superior anti-corrosion advantages.
Wide range of applications
Center Enamel has independently developed more than 200 glaze formulas and patents, and can develop customized enamel formulas according to customers' storage medium requirements for enamel assembled tanks, making the storage tanks widely applicable to different fields.
Designed to suit local conditions
Based on the project construction location, multiple targeted designs such as wind resistance and earthquake resistance were adopted for the enamel assembled tanks to ensure that the enamel assembled tanks will not be damaged by natural factors such as earthquakes and typhoons.
Make reasonable use of the environment
Enamel assembled tanks can be flexibly designed and customized in tank size and color according to customer needs and environmental requirements, saving floor space and suitable for modern construction requirements.
High degree of standardization
The steel plates and main components of the enamel assembled tanks are produced in a standardized manner through automated equipment in the factory, and are packaged and transported to the project site for standardized assembly. From production to installation, the design plan is strictly followed to ensure standardized manufacturing of storage tanks.
Easy and quick installation
The enamel assembled tank adopts on-site assembly method, which is simple and fast to install, is less affected by weather factors, and has a short and controllable installation cycle. After it is completed and put into operation, the storage tank can be dismantled and reinstalled, making it easy to relocate and expand its capacity.
