1. 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 ~/ 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, %~% of the suspended solids can be removed. After more than one month 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 density of the sludge. Moisture content. The sludge is regularly removed and transported to landfill or used as fertilizer.
2. Characteristics of fiberglass septic tank
Environmentally friendly and non-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.
3. Comparison of corrugated hand lay-up septic tanks
Name Mechanically wound FRP septic tank Corrugated hand lay-up septic tank
Process features Unique manufacturing process, mechanical winding, multi-angle + high tension , the overall winding molding ensures that the quality and indicators reach the extreme. Manual operation involves large human factors and the quality is difficult to guarantee.
Structural hierarchy The structural hierarchy and function are perfectly combined. The inner lining layer, secondary inner layer, transition layer, strength layer and outer protective layer are automatically produced by program-controlled machinery according to special mechanical design software. Without a layered process, it is difficult to meet the product’s requirements for strength, leakage resistance, and corrosion resistance at the same time.
The production efficiency is highly mechanized and automated, the product quality is stable, the labor intensity is low, the production efficiency is high, and the factory-like and assembly-line production is adopted. The strength and dimensional accuracy of the products are low, the quality of the products is difficult to control, and the human factor is high.
Product Appearance The appearance of the product is uniform in color, smooth and flat, and the appearance quality can be maintained after long-term use. The appearance of the product is uneven and the color is uneven. After a period of use, the appearance of the product changes significantly, and delamination, cracks, etc. begin to appear.
The inherent quality and mechanical properties are high, the strength is good, and the sealing performance is good, which can ensure that the service life is the same as the building life, and can be repeatedly excavated and used. The structural integrity is poor, the strength is low, it is easy to deform, leakage and damage occur, and it can only be used for one construction time.
4. 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).
. When the pit size is installed individually, the pit length is product length +, width is product width +, and 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 the distance between products should also be kept. The minimum width is such that when a single product is larger than cubic, 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 trenching pit
The user should excavate the foundation trench according to the model of the septic tank, model size, elevation and laying out line in the engineering design drawings. Comply 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.
, 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.
, The 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 drawing. It is required that after this product is hoisted into place, the levelness should be measured and the cushion should be 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 is strictly forbidden to use construction waste as backfill soil. Large sharp-cornered stones in the backfill soil should be removed. The backfill soil should be compacted layer by layer, for each layer. Manual compaction should be used, and local violent force should be avoided. Impact, the backfill soil around the pool must be dense. The density shall be carried out according to the design or construction regulations.
After the backfilling of the masonry connection shaft meets the requirements of the construction specifications, the entrance and exit connection shaft can be built. The connection shaft shall be constructed according to the national standard atlas.
, Preliminary acceptance
①The 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 or 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.
5. Scope of application
Preliminary treatment of domestic and fecal sewage in industrial and civil buildings such as residential buildings, office buildings, schools, nursing homes, corporate workshops, living rooms, etc.
