Silica Sand Honeycomb Water Storage and Purification Rainwater Harvesting Module

Silica Sand Honeycomb Water Storage and Purification Rainwater Harvesting ModuleAddressing the issues of lacking filtration and disinfection, wastage of water resources, and environmental pollution, to resolve the above problems,

this utility model proposes a silica sand honeycomb water storage and purification technology.

Silica Sand Honeycomb Structure Biological Purification and Preservation System (integrated collection, filtration, purification, storage, and preservation)
—Effectively solving the worldwide challenge of stored rainwater preservation without odor
Silica sand permeable water-filtering blocks, silica sand self-cleaning reservoirs, breathable anti-seepage sand preservation composite materials, etc.
Reservoirs can be built beneath squares, parking lots, park green spaces, etc., conserving valuable land resources.

Features:
1. Integrated collection, filtration, purification, and preservation, providing an effective technical solution to address blue-green algae and water blackening and odor issues.
2. Multi-layer filtration + microbial self-purification.
3. Essentially maintenance-free in the long term.

Core Technology 1—Sand-Based Breathable Anti-Seepage Technology
Filtration Performance Test:
The silica sand well cylinder is filled with micro-pores, filtering wastewater layer by layer like a membrane, achieving a SS removal rate of over 95%.

Biological Purification: Biofilms attached to the well walls degrade wastewater and organic pollutants. The breathable anti-seepage preservation composite material at the pool bottom increases dissolved oxygen in wastewater by 8-10 mg/L, providing essential conditions for aerobic bacteria survival.
· Inter-particle Effect: The well wall pores divide wastewater into small particles, ensuring full contact with biofilms for more efficient biological purification.
· Silica Sand Microfiltration: The silica sand well cylinder, filled with micro-pores, filters wastewater layer by layer like a membrane, efficiently removing colloids or suspended solids from water.
Conclusion: The silica sand honeycomb structure biological filter deeply purifies wastewater, with effluent quality reaching Class III surface water standards.
