Principle of FRP Septic Tank
FRP Septic Tank is a treatment facility that uses the principles of sedimentation and anaerobic fermentation to remove suspended organic matter in domestic sewage. It is a primary transitional treatment structure. Domestic sewage contains a large amount of feces, paper scraps, and pathogenic insects. The concentration of suspended solids is ~3/, and the concentration of organic matter is between ~/, of which the concentration of suspended organic matter is ~/. When sewage enters the septic tank and undergoes sedimentation, ~ suspended solids can be removed. After more than 3 months of anaerobic digestion of the settled sludge, the organic matter in the sludge is decomposed into stable inorganic matter, and the raw sludge is converted into stable mature sludge, which changes the structure of the sludge and reduces the cost of the sludge. of moisture content. The sludge is regularly removed and transported to landfill or used as fertilizer.
Features of Xindadi fiberglass septic tank:
, environmentally friendly and no leakage. The product is made of glass fiber, high-strength resin and other mechanical windings and formed in one go. It has good sealing performance and will never cause breakage or scum layer formation in the tank caused by foundation settlement. It completely solves the problem of groundwater pollution from brick septic tanks. , ensuring the reliable operation of the septic tank and the function of anaerobic manure.
, high compressive strength. Made of high-quality fiberglass composite materials, it has the advantages of acid resistance, alkali resistance, tensile resistance, compression resistance, impact resistance, etc., and its service life can be synchronized with the building.
The processing effect is good. The staggered-layer design of the bulkheads of this product changes from the original direct-flow flooding to the circulating flooding. The matrix transfer is smooth. The application of the anaerobic biological filter filler system intercepts more biomass and has the same sewage treatment capacity. The capacity of a traditional septic tank has more than doubled.
, easy to install and construct. The product is lightweight and easy to transport. The overall hoisting, quick construction, grooving, hoisting and well laying can be completed on the same day.
, Economic indicators are low. It is cost-effective and has a short construction period. It is an environmentally friendly product that is strongly promoted by the urban construction department.
Installation instructions:
The horizontal clear distance between the fiberglass septic tank and the building should not be less than the height difference between the base of the septic tank and the base of the building.
When the foundation of this pool is solid, it can be laid on natural plain soil and leveled with yellow sand. (In case of special foundation, special treatment should be carried out).
Trough size: When installed in a single installation, the length of the pit is + product length, width is product width +, depth is effective height of the product + height of the inlet and outlet connecting well. When installed in combination, the distance between the product and the pit wall is, and should also be reserved between products. The minimum width is such that when a single product is larger than 3 cubic meters, the spacing between products must be at least .
After the pool is put in place, water must be poured into the pool body to stabilize it and prevent it from floating.
When backfilling, remove stones, bricks and other hard objects from the soil, fill and compact them layer by layer manually, and do not violently collide with the pool body.
Other operations can be carried out with reference to the relevant construction standards for brick septic tanks.
, Construction operation procedures:
, Laying out the trench pit:
The user should excavate the foundation according to the model, model size, elevation and laying line of the septic tank in the engineering design drawings. The grooves are in compliance with all relevant national construction regulations. When the groundwater level is high, the excavation trench must be drained to prevent water accumulation in the foundation pit and slope collapse.
B. Base cushion:
Use yellow sand, remove the larger sharp-cornered masonry or hard debris contained in the sand, and level and compact it. If groundwater is encountered and the base soil quality is extremely poor or the backfill is installed in a combined manner, in addition to the sand and ash cushion, plain concrete (thickness not less than 10%) needs to be poured.
. Septic tank is installed in place:
When hoisting, you must pay attention to the direction of the entrance and exit of the septic tank. The end pointed by the arrow is the exit direction. Check whether it meets the requirements of the engineering design drawing. The elevation of the septic tank must comply with the engineering design. The figure requires that after the product is hoisted into place, the levelness is measured and the cushion is partially adjusted to make it level.
Septic tank water filling
After the installation is in place and meets the requirements, surround the soil below and fill the tank with water to make it stable.
Layered backfilling: It is strictly prohibited to use construction waste as backfill soil. Large sharp-cornered stones in the backfill soil should be removed. The backfill soil should be compacted in layers, with 3 layers per layer. It is advisable to compact it manually and avoid partial compaction. Violent impact must make the backfill soil around the pool dense. The density shall be carried out according to the design or construction regulations.
Building connection shafts: After the backfill meets the requirements of construction specifications, the entrance and exit connection shafts can be built. The connection shafts shall be constructed according to the national standard atlas.
, Preliminary acceptance:
① The diameter of the septic tank inlet and outlet pipes is ~, which can be directly built into the well wall. The connection between the outer wall of the pipe and the well wall should be filled with cement mortar.
②The diameter of the water inlet pipe of the septic tank water inlet inspection well should not be larger than that of the inspection well. The inspection inlet and outlet should be constructed based on the principle that the top of the pipe is connected flat.
③ After the septic tank is initially completed on site, it is strictly prohibited to dump construction waste or domestic waste.
Scope of application
Preliminary treatment of domestic and fecal sewage in residential buildings, office buildings, schools, nursing homes, corporate workshops, living rooms and other industrial and civil buildings.
Advantages:
1. Save money
Fiberglass septic tanks are produced in a factory, mechanized, batched, and integrated manner, using new processes and new materials. They are small in size and large in effective volume.
2. Save labor and time
The fiberglass septic tank has an overall shape, is light in weight and high in strength, and is quick and convenient to install.
3. Save land
FRP septic tank saves land excavation area.
4. High Efficiency
Fiberglass septic tanks have good sealing performance and can efficiently process feces. The anaerobic decay effect is more than twice that of traditional septic tanks.
5. Environmental protection
The fiberglass septic tank is produced in an integral shape, has good sealing performance, does not leak, does not pollute surface water, and does not corrode the flowers, trees, wires and cables around the septic tank. The pool uses high-level siphon diversion, multiple sedimentation, and multiple purifications.
6. Durable
The fiberglass septic tank is made of new material fiberglass, which is resistant to aging, acid and alkali, and has a service life of more than 10 years.
7. High pressure resistance and compressive strength
Fiberglass septic tanks are resin-sealed and cylindrical in shape, and their compressive strength is several times higher than that of polygons and squares.
8. No post-management, long cleaning cycle
Fiberglass septic tanks are underground, powerless, and require no maintenance or management in the future.
