Inclined plate (tube) sedimentation tank is a shallow pool precipitation theory to design an efficient modular sedimentation tanks; also referred to as the shallow pool sedimentation tanks. Regional settings in the settlement of many intensive inclined tube, inclined plate, suspended in water by precipitation of impurities in the inclined plate or inclined tube, the flow of water rise along the inclined plate or inclined tube, isolated from the sludge under gravity along the inclined plate (tube) downward slide the bottom, and then concentrated discharge. This pond can improve the efficiency of precipitation 50 ~ 60% can increase the processing capacity of 3 to 5 times in the same area. Sedimentation of the design flow according to the raw wastewater test data are generally required to use coagulant dosing. Sedimentation Clean Water Act is suspended layer above the sludge to the formation of the installed angle of 60 degrees inclined tube, then raw water suspended solids, solids or formed by adding coagulant flocs of alum in the inclined tube The bottom side of the surface area of accumulation into a thin mud layer, relying on gravity to slide back into the sludge suspension layer, and then sink into the mud bucket. Discharged into the sludge pool to be dealt with separately or comprehensive utilization of pipe from sludge. Supernatant gradually increased to the set of pipes discharge can be discharged directly or reuse.

V. Structure description
Inclined tube, inclined plate material: glass fiber reinforced plastic (FRP) polyvinyl chloride (PVC), polyethylene (PE) polypropylene (PP)
2 inclined tube cross-section is generally hexagonal, inclined plate section parallel to the plate, or a sine wave-shaped plate.
The top of the (board) 3. Inclined tube above water height of 1.0-1.5m below the bottom of the water distribution area to a height of not less than 1.0-1.5m. Mechanical sludge with the water district shall be greater than 1.6m, ease of installation and maintenance.
Inclined tube (board) in water for Re less than 500, Fr of the number of 10-3-10-5
Inclined tube design flow rate for the 10-20mm / s for 1.0-4.0mm / s, the inclined plate.
Sixth, install and use
Fixed. Inclined pipe installation with glue or electrical bonding and other methods of bonding. Inclined plate, parallel plate, with the support frame fixed waveform inclined plate fixed to the mandrel screw.
Installation tilt direction should not make the water flow straight into the inclined tube (board).
Regular flushing, rational management, reduce clogging caused by biofilm soaring.
Four inclined tube (board) plane may not withstand a concentrated load.
5 shall not be installed in the inclined tube (board) the use of fire in the region.
Seven, the sedimentation principle
Ramp, inclined tube referred to as settling ponds for the shallow pool, is built in a shallow pool of precipitation based on the principle. Has an ideal sedimentation tank, pool cellar V, surface area A, the cell length L, width = B, H = H, treated water Q, the residence time t, the settling velocity of U0. V = Qt, H = Uot, Q = Uot / H = U0A by the shallow pool sedimentation principle known: the precipitation efficiency is only a function of the surface area of the sedimentation tanks, and nothing to do with the depth. When the sedimentation tank volume for the given value, the pond the more light the greater the value of A, the higher the precipitation efficiency. So, if the sedimentation tank by a high degree of separated n-tier, that is separated by n height h = H / n shallow settlement unit in Q the same conditions, the particle sedimentation depth decreases from H to the H / n, then the sedimentation tank can be completely removed teeth. U U0 grain settling velocity range from expanded to u of U0 / n, the settling velocity u <U0 particles can be removed fraction increased from u/U0 to nu/U0, so that the settling ponds of suspended particles to In addition to the rate n times larger than the original. Obviously, separated by a few more shallow and a corresponding increase in removal rate. This principle can be made of the inclined plate or Sedimentation.
