Carbon Steel Underground Integrated Equipment
Product Overview
The Carbon Steel Underground Integrated Equipment is a compact and efficient solution for wastewater and reclaimed water treatment. It is installed below ground level, saving surface space and providing a clean, noise-free environment. The equipment integrates multiple treatment processes such as sedimentation, biological treatment, filtration, and disinfection within a sealed structure.
Constructed with high-strength carbon steel and anti-corrosion coatings, it ensures long-term durability and stable operation even under complex underground conditions.
Working Principle
Raw wastewater enters the equipment through the inlet pipe and sequentially passes through different internal chambers such as the sedimentation tank, biological treatment zone, and filtration section.
Suspended solids are first removed by sedimentation.
The biological section decomposes organic matter through aerobic or anaerobic reactions.
The filtration and disinfection stages further purify and sterilize the water.
The treated effluent meets discharge or reuse standards, while sludge is periodically removed through the sludge discharge outlet.
Main Components
nlet Chamber: Guides raw wastewater into the system evenly.
Sedimentation Section: Removes suspended solids through gravity settling.
Biological Treatment Zone: Performs aerobic or anaerobic treatment to remove organic contaminants.
Filtration Unit: Further polishes the treated water to improve clarity.
Disinfection Chamber: Ensures the effluent meets hygienic discharge or reuse standards.
Sludge Storage and Discharge System: Collects and removes accumulated sludge.
Ventilation System: Prevents accumulation of harmful gases in the underground chamber.
Carbon Steel Shell: Fully welded, coated with epoxy or polyurethane for corrosion resistance.
Access Cover and Maintenance Port: Allow convenient inspection and maintenance.
Control Cabinet: Integrates electrical control, automation, and monitoring functions.
