The deposition ship principle that the utility model provides: according to flow characteristics, produce different flow rate, cause jet suction through changing the runner captured area; Accelerate sludge settling and mud-water separation; Mud after the separation is directly got back in the oxidation ditch system, need not additionaling power, and through adding a cover; Can avoid phenomenons such as ship shape sedimentation basin surface green alga grows, be a kind of novel mud-water separation technology.
Compared with prior art, the beneficial effect of the utility model is:
1, do not produce the mud come-up, cooperate sloping plate deposition or tube settling, SS is more stable for the water outlet concentration of suspension.Water outlet SS can be controlled in the 15mg/L.
2, owing to no any power-equipment, Maintenance free.
3, place biological tank, need not to build secondary sedimentation tank, almost do not have the loss of flood peak, adopt efficient, small-sized boat form settler, reduce construction cost and land area significantly.
4, directly in oxidation ditch, system need not exteenal reflux to mud, need not join return sludge pump.The sludge concentration of biochemistry pool can reach more than the 10000mg/L, and disposal ability, impact resistance significantly improve.
5, the deposition hull is long-pending little, and is simple in structure much smaller than existing horizontal sedimentation tank length and each item specification requirement, and making is simple and expense is low.
6, under the deposition ship jet-flow aeration can be installed, not influence sedimentation effect; Utilize system's denitrogenation dephosphorizing for detesting the anoxic zone when not carrying out aeration.Because mud is discharged fast, and phosphorus does not discharge in sedimentation basin basically, it is up to standard to be beneficial to the water outlet total phosphorus in addition.
7, be provided with the automatic discharge device, need not labor cleaning's scum silica frost basically, the pond face is clean.
8, can realize all adding a cover, installation security, view is beautiful.
Description of drawings
Fig. 1 is the plan structure sketch map that the small-scale sewage of the utility model is handled boat form sedimentation basin device;
Fig. 2 is the cross-sectional view that the small-scale sewage of the utility model is handled boat form sedimentation basin device.
Among the figure, arrow b representes water (flow) direction, and a-a representes water surface curve.
The specific embodiment
Referring to Fig. 1 and Fig. 2, a kind of small-scale sewage of the utility model is handled boat form sedimentation basin device, comprises a hull, and this hull Parallel to the flow direction is divided into inhalant region A, settling zone B and exhalant region C successively.Establish water inlet 1 and deflector 2 in the inhalant region A; Spoil disposal plate 3 and type sloping plate component 4 and cover plate 8, exhalant region C established slag trap 7, scum pipe 5 and outlet pipe 6 bottom settling zone B established.
32 meters of whole length of hull, wide 12 meters, high 0.7 meter.Water inlet 1 is located at fore, and is consistent with water (flow) direction in the oxidation ditch.The supernatant overflow gets into exhalant region, and water outlet enters sterilization pool through pipeline and perhaps can build jointly with biological filter cloth filter tank, activated carbon filter, milipore filter filter tank etc., further carries out advanced treating, and small-sized boat form sedimentation basin disposal ability reaches 100 tons/day.The material that small-scale sewage is handled the employing of boat form sedimentation basin is generally steel plate: because hull does not stress, available 1-2mm corrosion resistant plate and the welding of stainless angle steel or 2-3mm fiberglass are welded; Also can adopt common angle steel to add iron plate processing, but should perform anticorrosion.
Spoil disposal base plate 3, hull lower base spoil disposal plate should be noted water, air vibration, last plate must be below one plate of back; Form wrong stack structure, the gap is as far as possible littler, generally is controlled at the 2-5 centimetre; In the present embodiment, the distance between header board 31 and the back plate 32 is 4 centimeters.Settling zone hull bottom one has 10 spoil disposal base plates that communicate with oxidation ditch 3 to be formed, and each base plate 3 comprises first half and latter half of for the shape of bending.The gradient 60 degree of spoil disposal base plate, the spoil disposal plate should design and extend to outboard, otherwise is prone to produce disturbance, and gas can overflow in ship when serious, can't precipitate.
" bubbling " zone in the deposition ship has been eliminated in swash plate 4 design basically, makes current held stationary state in the deposition ship, and in the present embodiment, swash plate is long to be 50cm, and the inclination angle is 75 degree, and swash plate 4 assemblies are fixed on the base plate spoil disposal plate 3.In another embodiment, swash plate 4 also can adopt the inclined tube design.
The boat form precipitation process of the utility model is following: activated sludge gets in the sedimentation basin from water inlet 1, and the suspended sludge concentration 4000mg/L of control boat form sedimentation basin is under the effect of cowling panel 2; Flow downward, flow velocity descends rapidly, and under the gravity effect; Muddy water begins to separate, and isolated activated sludge is deposited to hull bottom, and activated sludge high-velocity flow alow drives down through 3 discharges of bottom spoil disposal plate; And can not cause the phenomenon of mud come-up, and come back to oxidation ditch.Hull is provided with type sloping plate component 4, has increased settling area, has improved mud-water separation efficient, and supernatant progressively passes through the sloping plate deposition effect under water outlet drives, further mud-water separation.Surface scum is guaranteed the stable of effluent quality through outside the scum pipe 5 discharge ponds.
The utility model can also carry out some distortion according to pond shape, for example: be toroidal (garden with one heart), the series connection of a plurality of boat form sedimentation basin or the like.
The utility model can be built jointly with biological filter cloth filter tank, activated carbon filter, milipore filter filter tank etc., and further advanced treating through the mud-water separation effect of boat form sedimentation basin, has reduced boat form sedimentation basin water outlet load, reduces the impact of water body to the biofilter.
An above-mentioned specific embodiment that is merely the utility model, but the design concept of the utility model is not limited thereto allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
