Background technology
To town domestic sewage, adopted the brick mix structure septic tank to handle originally.The brick mix structure septic tank need be constructed with construction work, and the construction trouble needs maintenance after the construction; Can't avoid owing to seepage bring to underground contaminated water source problem; Because soil property was soft near seepage also can cause structure foundation, may cause settlement of foundation.For addressing the above problem, it is hexagonal combined septic tank that people design the cross section, separates with dividing plate in the pond, and dividing plate is provided with the direct current through hole.At pond body leading portion, the nature corruption is carried out in heavy one-tenth fractional precipitation, and clear liquid flows out through water outlet through dividing plate orifice flow to pond body back segment.Though this septic tank is simple in structure, it has still adopted original direct current flashing formula excrement principle, changes the excrement weak effect, and it is long to change the excrement cycle.
Summary of the invention
The monoblock type septic tank that provides a kind ofization excrement effective is provided the object of the invention.
For reaching above-mentioned purpose, the present invention adopts following technical scheme: the monoblock type septic tank, comprise that top is provided with the round shape pond body of entery and delivery port and soil shifting opening, be divided into settling tank and treating pond with the knifing bin isolation board in the body of pond, bin isolation board is provided with the stuffing box of filling the sewage disposal filler, the stuffing box side is provided with sewage routeway, and the bin isolation board middle part corresponding with stuffing box is provided with the sewage duct, sewage routeway and sewage hole link; The sewage disposal filler is installed in the treating pond.
Settling tank has more than two, is interconnected by the sewage duct therebetween.
The suspension type water treatment filler vertically is installed in stuffing box and the treating pond.
Be provided with soil shifting opening above the settling tank, be provided with open holes above the treating pond.
Pond body inwall is provided with ring stiffener, and body two ends, pond are provided with radially stiffening web.
Pond body integral body is made by glass-reinforced plastic material.
Among the present invention, septic tank adopts one-piece construction, and Chi Tizhong is divided into settling tank and treating pond with bin isolation board.If adopt the two-stage settling tank, then be divided into one-level settling tank, second-level settling pond and treating pond three parts in the body of pond, sanitary sewage enters the body of pond behind the one-level settling tank from septic tank top water-in, heavy composition is changed the excrement processing at the bottom of sinking to the pond, the composition that proportion is little floats on the upper strata, can pull out from soil shifting opening.The stuffing box side sewage routeway circulation that upper strata sewage is installed on bin isolation board enters stuffing box, in stuffing box with the suspension type water treatment filler of wherein installing (the 3 D elastic filler polyvinyl tow of producing as the strange triumphant environmental protection equipment of Yixing City company limited) catalytic oxidation.It is circulation flashing excrement principle that this design changes original direct current flashing excrement principle, the mixing that has increased sewage greatly with persist the time, make that the catalytic oxidation time of sewage and filler is longer, the organic matter biodegradation degree is higher.Sewage disposal filler (as the polyvinyl tow) also is installed in the treating pond, a large amount of microbial enrichments is arranged in this, sewage is when flowing through filler, and organism is able to abundant degraded under microbial process, and the COD index is reduced to minimum level in the sewage effluent.The present invention can adopt glass-reinforced plastic material to make, but factory carries out large-scale mass production, the production efficiency height.Product is got round shape, and bearing capacity is strong, and in the cylindrical shell and cylindrical shell two ends have stiffening web, intensity height, long service life.The product installation rate is fast, has shortened construction unit's completion time of project in later stage greatly, and is more favourable in, the higher area of ground water table on the high side in quantity of precipitation and the winter construction.Ne-leakage in the use, the particularly practicality of phreatic area is not drunk in the water resources shortage in the polluted underground water source.
Embodiment
Embodiment, monoblock type septic tank are made by glass-reinforced plastic material.Comprise that both upper ends thereof is provided with the round shape pond body 3 of water-in 1, water outlet 2, be divided into one-level settling tank 5, second-level settling pond 6 and treating pond 7 with bin isolation board 4 in the pond body 3, bin isolation board 4 is provided with the stuffing box 9 of filling sewage disposal filler 8, stuffing box 9 two sides are provided with sewage routeway 10, bin isolation board 4 middle parts corresponding with stuffing box 9 are provided with sewage duct 11, and sewage routeway 10 is communicated with sewage duct 11; Sewage disposal filler 8 is installed in the treating pond 7.The vertical sewage disposal filler of installing 8 is a suspension type 3 D elastic filler polyvinyl tow filler in stuffing box 9 and the treating pond 7.Two are provided with soil shifting opening 13,14 and are the port lid of removing contamination above the settling tank.Body 3 inwalls in pond are provided with ring stiffener 12, and body 3 two ends outer walls in pond are provided with the stiffening web 15 of projection.16 is the open holes that is provided with on the bin isolation board, is used to connect the stiffening web of bin isolation board and Chi Tishang.17 is breather hole, and 19 is the standing bolt of bonding pad case retaining plate 18 and bin isolation board 4.
