  FRP septic tank: ★ Overview of FRP septic tank:
FRP septic tank refers to the equipment specially used to treat domestic sewage, which is made of synthetic resin and glass fiber reinforced materials
It has the advantages of light weight, high strength, good toughness, corrosion resistance, bright color and mirror finish
FRP septic tank temporarily stores excreta and makes it decompose initially in the tank to reduce the solid content in the discharged sewage
FRP septic tank is mainly applicable to the domestic sewage purification treatment of civil buildings such as living areas of industrial enterprises and living quarters of urban residents

★  Principle of FRP septic tank:
FRP septic tank is a treatment facility that uses the principle of sedimentation and anaerobic fermentation to remove suspended organic matter in domestic sewage
It is a primary transitional domestic sewage treatment structure
Domestic sewage contains a large amount of feces, paper scraps and pathogenic insects
The concentration of suspended solids is 100 ~ 350mg / L, and the concentration of organic matter is BOD5 The concentration of suspended organic matter BOD5 is 50 ~ 200mg / L
The sewage enters the septic tank and can remove 50% ~ 60% of suspended solids after 12 ~ 24h sedimentation
After more than 3 months of digestion, the sludge that is easy to decompose into inorganic sludge is stabilized, and the water content in the sludge is reduced
The sludge is regularly removed, transported out, buried or used as fertilizer

★  Process flow of FRP septic tank:
The septic tank deposits sludge
The bottom is deposited sludge, the surface is floating sludge, and the middle is suspended sludge and sewage
The septic tank is divided into two septic tanks or three septic tanks by a partition wall
The water passage hole on the partition wall is located in the middle
If the septic tank is not cleared in time, when the deposited sludge in the septic tank exceeds the height of the water passage hole, the sludge will block the hole, Cause blockage of septic tank
Firstly, the sewage is discharged from the water inlet to the first grid
In the first grid, the solids and parasite eggs with large proportion are precipitated, and the anaerobic bacteria in the pool water are used to start the preliminary fermentation and decomposition
The sewage treated in the first grid can be divided into three layers: pasty fecal skin, relatively clear fecal liquid and solid fecal residue
After preliminary decomposition, the fecal liquid flows into the second cell, while the fecal skin floating above and fecal residue deposited below remain in the first cell for further fermentation
In the second cell, the fecal liquid continues to ferment and decompose, the insect eggs continue to sink, the pathogens gradually die, the fecal liquid is further harmless, and the thickness of fecal skin and fecal residue is significantly reduced compared with the first cell
The fecal liquid flowing into the third grid has generally been rotten, in which the bacteria and parasite eggs have been basically killed
The function of the third grid is mainly to temporarily store the basically harmless fecal liquid precipitated
Finally, the fecal liquid precipitated again flows into the municipal pipe network through the drainage pipe
The four-stage septic tank has one more fermentation and corruption process than the three-stage septic tank, with more refined process and cleaner water quality

★  Features of FRP septic tank:
1
The installation and construction is fast and the construction period is very short
The factory has integrated production, one-time overall forming, one-time hoisting in place at the construction site, and the installation can be completed in half a day, which greatly improves the construction efficiency, shortens the construction cycle, and improves the economic and social benefits

2
Small floor area
The product has compact structure and small floor area
The actual floor area is about 60% of the traditional septic tank, saving land resources

3
Patented design, high compressive strength
The appearance of the product is cylindrical design
Both ends of the cylinder are designed and manufactured by mechanical concave convex surface
The cylinder is designed and manufactured by mechanical winding process and high compression structure
The compressive strength and bearing capacity are high
After construction, the product can carry 40t trucks above

4
The material is corrosion-resistant and has long service life
The product is mainly made of glass fiber reinforced unsaturated polyester resin and high-strength glass fiber composite, which has no corrosion, acid-base resistance, aging and deformation
The product cylinder is designed and manufactured by mechanical winding process and high compression structure, with high compression and impact strength and durability, so as to prolong the service life of FRP septic tank

5
The product has the advantages of low cost, high quality and low price
The cost of this product is about 20% lower than that of reinforced cement concrete septic tank, which is basically the same as that of brick septic tank
The environment-friendly septic tank is affordable and can be borne by users in all walks of life
It is deeply loved by real estate companies and construction general contracting units

6
Patented technology, good water treatment effect
The FRP septic tank is internally provided with a partition board, and the water passage holes on the partition board are staggered up and down, which is not easy to form swirling flow, avoids short circuit and prolongs the actual residence time of sewage; At the same time, The partition divides the whole tank into several parts: including multistage biochemical chamber, clarification chamber, etc
the biochemical chamber is equipped with high efficiency & ldquo; KWS biological filler & rdquo;, A large number of microorganisms are attached to the filler, which greatly increases the contact area and time between sewage and microorganisms, greatly improves the reaction efficiency, removes the solid and liquid organic matter in the septic tank, and reduces and makes the sludge harmless, The treated effluent meets the class III, class II, class I or reclaimed water reuse standards specified by the state

★  Usage of FRP septic tank:
1
The selection of FRP septic tank is based on different buildings, and the design parameters are calculated by the single project designer

2
The location of FRP septic tank shall not affect the building foundation in principle; Generally, the distance from the domestic and drinking water pool shall not be less than 10m The distance from underground water intake structure shall not be less than 30m When the foundation plane of the building is higher than that of the septic tank, the distance between the outer wall of the septic tank should not be less than 2m When the foundation plane of the building is lower than that of the septic tank, the clear distance between the outer wall of the septic tank and the outer wall of the building should not be less than 5m

3
The overall FRP septic tank shall also be covered with soil at least 0
3m The maximum covering soil should not exceed 3M
In cold areas, when the minimum temperature is lower than - 10 ℃, the soil covering depth of septic tank shall not be less than l2m The average temperature of the septic tank should be set below - 13 ℃ in this area, and the average temperature of the septic tank should be set below - 13 ℃

4
The FRP septic tank shall be installed under the green belt, lawn and sidewalk, and the covering soil shall not exceed 1
5m; It can also be installed in road sections

5
Well cover: when the car is not available, lock the light double-layer well cover and cover seat; When passing the vehicle, the heavy double-layer lock is adopted
The FRP septic tank also considers the needs of greening in the community or paving in the road square
The cast iron or polymer well cover is flat with the ground
At the paved ground, the well cover can be properly lowered to the bottom of the paved floor brick
When the paved floor brick on the well cover must be opened when the well cover needs to be opened

6
If the volume of FRP septic tank exceeds 50m3; Two single tanks can be set in parallel or in series
If they are connected in series, the designer and the user must notify the manufacturer in advance, and the distance between the outer walls of the tank shall not be less than 500mm

Common sense: 178 When you put on makeup, put the wet cosmetics into the fridge
After a few minutes, put the cold sponge on the skin with good foundation
You will feel that the skin is extra cool and the make-up is very fresh
