Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
A structure for the double-deck rectangular sedimentation tank of surface water purifying of drinking water, as Figure 1-3, is made up of lower floor's inhalant region, lower sediment district, upper strata inhalant region, settling zone, upper strata, exhalant region, lower floor sludge discharging area and sludge discharging area, upper strata.
Upper strata inhalant region, lower floor's inhalant region all adopt the water distribution of water inlet perforation tracery wall 1, play even moisturizing and energy dissipating effect.Water inlet perforation tracery wall 1 adopts brick or concrete block masonry, and outside eyelet, part adopts cement sand plaster; Tracery wall is arranged water inlet eyelet up and down and is staggeredly arranged, simultaneously the wall not apertured eye of 0.3 ~ 0.5m place to pond bottom part more than precipitation face, and barrel hole size and quantity can adjust according to flow of inlet water, control aperture flow velocity and are not more than 0.15 ~ 0.2m/s.
For obtaining good sludge discharge effects, lower floor sludge discharging area adopts many blowdowns bucket 6 spoil disposal, and sludge bucket 6 Bian Bi inclination angle adopts 60 °, discharge pipeline 7 is set in sludge bucket 6, sludge bucket 6 is inserted in discharge pipeline 7 lower end, and discharge pipeline 7 upper end is connected with spoil disposal house steward, utilizes the hydrostatic pressure spoil disposal of upper and lower two-layer Chi Shui.At the bottom of pond, sludge discharging area, upper strata, longitudinal gradient i is not less than 0.01, adopts monobucket spoil disposal, namely sends on upper strata at the bottom of slope, sludge discharging area and arrange single sludge bucket 6, to drive a vehicle 5 sludge buckets 6 sludge scraping being entered upper strata, then by sludge pump suction, realize spoil disposal operation by scraping mud; The settling zone cross-section of river expands gradually, and flow velocity reduces gradually, and particle under gravity free sedimentation occurs.Larger and less hydraulic surface loading can be got respectively by settling zone, upper strata, lower sediment district, to obtain good deposition efficiency.Specifically, the settling zone, upper strata of pond body, the length-width ratio in lower sediment district are not less than 4, and length depth ratio is not less than 10; Settling zone section expands gradually, and flow velocity reduces gradually, and particle under gravity free sedimentation occurs, and total sedimentation time controls in 3h; The desirable larger Design cooling load in lower sediment district, alleviates the Design cooling load of upper strata sedimentation basin greatly, to obtain good deposition efficiency.
Exhalant region realizes the collection of process water by arranging finger-type effluent weir 2, finger-type effluent weir 2 periphery arranges zigzag weir with a free fall, the degree of depth of the groove of finger-type effluent weir 2 gets 0.3 ~ 0.5m, and its length and width are then controlled by downflow weir rate of load condensate, and General Requirements downflow weir rate of load condensate is not more than 300m
3/ (md).The clear water collected is imported water header 3 by finger-type effluent weir 2, and the outfall sewer 4 then by water header 3 is installed is concentrated and discharged.
