Detailed description of the invention
For making the purpose of the embodiment of the present invention and technical scheme clearly, below in conjunction with the accompanying drawing of the embodiment of the present invention, the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiments. Based on described embodiments of the invention, the every other embodiment that those of ordinary skill in the art obtain under the premise without creative work, broadly fall into the scope of protection of the invention:
Collection clarification, membrane filtration and Treatment of Sludge integral type process device, and concrete structure is as shown in the figure.
The clarification of this collection, membrane filtration and Treatment of Sludge integral type process device and are made up of coagulant dosage system I, clarification system II and Treatment of Sludge III system.
Coagulant dosage in inlet channel 1, and is ensured coagulant and water inlet being sufficiently mixed of current by coagulant dosage system I. Thereafter inlet channel is divided into two water inlet pipes 2, and enters into the bottom of two clarification system II.In the present embodiment, coagulant adopts aluminium polychlorid, and its dosage is 12 ~ 15mg/L.
As shown in the figure: two clarification system II, it is connected with two water inlet pipes 2 respectively bottom it. Being suspension slime layer 3 in the bottom of clarification system II, its solid concentration is 2 ~ 3g/L. Suspension slime layer 3 top is the settling section 4 of degree of depth 1.5m, and settling section top is membrane filtration system 5. In the present embodiment, membranous system adopts ultrafilter membrane, and its design flux is 20L/m2H. Two membrane filtration systems corresponding for clarification system II and supernatant recovery membrane filtration system 11 are connected with going out water pump 7 by outfall sewer 6. And on the pool wall at suspension slime layer surface place, leave the mud hole 8 being connected with sludge treating system.
Sludge treating system III is connected with two clarification systems respectively by mud hole 8. Discharge pipeline 13 and sludge pump 12 are installed bottom sludge treating system. At 0.4m place, discharge pipeline top right angle setting diving mixer 9 in order to the unnecessary mud entered by mud hole 8 is carried out row mechanical thickening. Install swash plate 10 on top, mud district, swash plate height 0.8m in the present embodiment, inclination angle is 60 degree. Install clear liquid recovery membrane filtration system 11 in supernatant recovery area, in the present embodiment, film adopts the ultrafilter membrane identical with membrane filtration system 5. Membrane filtration system in sludge treating system III is also connected on outfall sewer 6.
Water inlet, after coagulant dosage system I dosing coagulant, respectively enters two clarification system II by two water inlet pipes 2. Entering after clarification system II and be sufficiently mixed with suspension slime layer 3, under the contact flocculation effect of suspension slime layer, the fine particle thing in water inlet forms bulky grain flco, and is upwardly into settling section 4 and tentatively completes mud-water separation effect. Floccule body after separation enters suspension slime layer 3 under gravity, and primary water is upwardly into membrane filtration system 5. Primary water enters outfall sewer 6 under the swabbing action going out water pump 7 after ultrafiltration membrance filter and flows out and become product water outside pond.
The unnecessary mud produced in two clarification system II runnings is entered in sludge treating system III by mud hole 8. Sludge condensation is completed under being installed on the mechanical thickening effect of blender of sludge treating system III bottom. Mud after concentration is discharged outside pond by discharge pipeline 13 under the effect of sludge pump 12. The current produced in concentration process flow up, by particulate separation in water under the effect of swash plate 10. Particulate matter after separation returns to mud district under gravity, and the supernatant produced then flows up and enter after supernatant recovery membranous system 11 filters outfall sewer 6 becomes product water, thus realizing the recovery of supernatant.
