Subsurface Integrated Rural Domestic Wastewater Treatment Equipment

Glass-fiber reinforced plastic septic tanks refer to equipment made from a synthetic resin matrix and glass fiber reinforcement materials, specifically designed for treating domestic wastewater.

Its lightweight, high strength, excellent toughness, corrosion resistance, vibrant colors, and mirror-like luster.

Fiberglass septic tanks are specialized equipment made from a synthetic resin matrix and reinforced with glass fiber materials, designed for the treatment of domestic wastewater. These tanks are actively promoted by the state as composite material products, offering advantages such as lightweight, high strength, excellent toughness, corrosion resistance, vibrant colors, and a glossy finish that resembles a mirror. They have far outperformed similar products made from ceramics, rigid plastics, and steel, and are widely used in industries such as chemicals, petroleum, construction, textiles, aviation, maritime, transportation, electricity, metallurgy, machinery, food, papermaking, and environmental protection. Fiberglass septic tanks are used in industrial and civil buildings like residential complexes for the purification and treatment of domestic wastewater. They temporarily store excrement, allowing for initial decomposition within the tank to reduce the solid content in the discharged wastewater.

1. Backfilling must meet construction specifications, allowing for the construction of clearwell (inspection well) on the pool. Clearwells come in two types: brick-lined and prefabricated reinforced concrete structures.

2. To prevent leakage from brick-lined well walls, the inner and outer walls of the well must be coated with waterproof mortar, 20mm thick (1:2 waterproof mortar with 5% of the waterproofing agent by weight of cement), and 45-degree beveled corners. The sloping surface should be 50mm thick. When there is groundwater, apply two coats of hot asphalt (or other waterproof coating) to the well wall, then backfill to the ground level requirements.

Advantages

One: Cost-saving: Glass-fiber reinforced septic tanks are produced through industrialization, mechanization, mass production, and whole-form manufacturing, utilizing new technology and materials. They have a compact size with a large effective volume.

Section 2: The integrated glass fiber septic tank design is labor and time-saving, lightweight yet high-strength, and easy to install.

Three, the land-saving glass fiber reinforced plastic septic tank saves excavation area.

Four, the glass fiber septic tank has excellent sealing performance, effectively treats feces, and its anaerobic decomposition effect is more than twice as good as traditional septic tanks.

Five, the environmental-friendly fiberglass septic tanks are produced in a monolithic shape, offering excellent sealing properties with no leakage or contamination of surface water. They do not corrode the surrounding flowers, trees, and electrical cables. The tank employs high-level siphon drainage with multiple sedimentations and purifications.

Six, durable fiberglass septic tanks are manufactured with new material fiberglass, resistant to aging and acids/bases, with a service life of over 50 years.

Section 7: High-pressure, high-compressive strength glass fiber reinforced plastic septic tanks with international 50 steel resin sealing, cylindrical shape, offering several times the compressive strength compared to polygonal or square designs.

Section 8: The glass-fiber septic tanks with no post-maintenance and long slag removal cycle are designed for underground installation, are non-powered, and require no maintenance or management thereafter.

Once the glass fiber reinforced concrete septic tank is in place, backfilling should be carried out. The lower part of the tank should be filled with sand and soil (height should not be less than half the diameter of the tank), and it is strictly prohibited to use construction waste as backfill material. Stones in the backfill soil should be removed, and the backfill soil should be compacted layer by layer, with each layer being compacted to a thickness of 30mm. It is advisable to use manual compaction. Avoid localized forceful impacts during backfilling (such as using air compactors), ensuring the backfill soil around the tank is compact and dense.
