Embodiment
As shown in Figure 1 and Figure 2, a kind of body refuse classification is from filtering Waste Water Treatment, and comprise water distribution weir 1, the upstream on water distribution weir 1 is to downstream: be provided with one-level partition wall 3, one-level training wall 4, secondary partition wall 6, secondary training wall 7, three grades of partition walls successively.Be provided with one-level water hole 2 bottom described one-level partition wall 3, be provided with bottom secondary partition wall 6 bottom secondary water hole 5, three grades of partition walls and be provided with three grades of water holes 8.Current are under the effect of described partition wall, training wall, and vertical folding backflows dynamic, and flow velocity is from fast to slow.Current enter next region by water hole bottom partition wall.
Form between the sidewall of the upstream on described water distribution weir 1 and one-level partition wall 3 macrobead tackle in pars granulosa I.
In forming between one-level training wall 4 and secondary partition wall 6, particle tackles fine particle district II.
Form fine particle between secondary training wall 7 and three grades of partition walls and tackle microparticle region III.
The sidewall in the downstream on three grades of partition walls and water distribution weir 1 forms tube settling mud accumulation area IV.
For sandstone processing waste water: major precipitation more than 50 μm particles in pars granulosa I in macrobead interception; Middle particle interception fine particle district II major precipitation more than 50 ~ 20 μm particles; Fine particle interception microparticle region III major precipitation more than 20 ~ 10 μm particles.
Be provided with inclined tube 9, Rinsing Area 10 in described tube settling mud accumulation area IV, bottom tube settling mud accumulation area IV, be provided with shore pipe 11.For sandstone processing waste water: in tube settling mud accumulation area IV, inclined tube 9 is arranged at pond upper position, and inclined tube more than 9 about 50cm clear water zone, it is Rinsing Area 10, Rinsing Area 10 collects water outlet.Inclined tube 9 is fixed by inclined-tube support, and inclined tube 9 end opening is had an appointment 50cm inhalant region, is deposition bucket below inhalant region, the fine particle body refuse that tube settling glides: be mainly less than 10 μm, slipping into deposition bucket under gravity, is shore pipe 11 bottom deposition bucket.
Spacing between described one-level partition wall 3, one-level training wall 4, secondary partition wall 6, secondary training wall 7, three grades of partition walls progressively becomes large.The settling velocity of homogeneity particle is relevant with granular size, and the larger sedimentation of particle is faster, and required sedimentation time is shorter, and the particle less required settling time is longer.By the increase of training wall, partition wall spacing, realize sewage in flow process, flow section increases, and realize flow velocity and progressively reduce, the particle for different-grain diameter provides different sedimentation time, is convenient to gradation.Thus realizing macrobead pars granulosa I precipitation in main macrobead interception, middle particle mainly precipitates in middle particle interception fine particle district II, and fine particle mainly precipitates in fine particle interception microparticle region III.Meanwhile, for the particle do not precipitated provides longer sedimentation time, the sedimentation of this grade particles is facilitated; The thinner particle be not blocked, enters next district, through longer time settlement.
Described water hole length is consistent with described partition wall length, and along water (flow) direction, water hole height progressively increases.Water hole length is consistent, highly increases, and flow section increases, and flow velocity classification reduces, and be convenient to the solids precipitation of different-grain diameter, its Main Function is identical with above-mentioned effect.In addition, due to current by water hole time, due to change in flow, influent side aperture periphery produces certain negative pressure, causes suction to the particle tackling sedimentation; By the difference of water hole aperture height, reduce the variable gradient of flow velocity, thus reduce flow velocity change to sedimentation and the disadvantageous effect of tackling particle.
Implementation step:
1), waste water enter macrobead interception in pars granulosa I, current from up to down flow, and in waste water, macrobead precipitates at first, and macrobead interception in pars granulosa I, progressively formed macrobead interception filtering layer.
2), current are through one-level water hole 2, upwards flow, transferred to by the effect of one-level training wall 4 and flowing downward, enter middle particle interception fine particle district II, the medium grain do not tackled in waste water precipitates at first, and particle tackles filtering layer in middle particle interception fine particle district II is progressively formed.
3), current are through secondary water hole 5, upwards flow, transferred to by the effect of secondary training wall 7 and flowing downward, enter fine particle interception microparticle region III, the fine particle precipitation of not tackling in waste water, and progressively form fine particle interception filtering layer in fine particle interception microparticle region III; Thus complete the classification filter certainly of body refuse.
4), waste water after filter, by three grades of water holes 8, enters tube settling mud accumulation area IV through classification, and by the effect of inclined tube 9, form upward flow tube settling, clear water is discharged by Rinsing Area 10.The deposition of tube settling mud accumulation area IV is discharged by shore pipe 11.
When deposit seeds in each region is piled up to a certain degree constantly, utilize top, water distribution weir 1 mechanical dredge device regular cinder-discharge, the sequencing in the pond flow through by current, first excavate the filter residue in pars granulosa I in macrobead interception, middle particle interception pond, II first, fine particle district, after completing waste residue eliminating, carry out pars granulosa I in macrobead interception, middle particle interception fine particle district II, fine particle interception microparticle region III, tube settling mud accumulation area IV again, from water to water outlet, remain the eliminating of pond filter residue.When excavating body refuse, a follow-up pond is tackled previous pond waste residue, and each body refuse surplus lower than edge on water hole, must not ensure from filtering system health.
Sandstone flushing waste water flows to settling tank, and in waste water, different-grain diameter silt particle etc. sink under gravity, the sand setting grain diameter in settling tank front end comparatively evenly, concentrate, water-permeable better, be convenient to mummification.For ease of body refuse mummification, the body refuse in each region separates mummification or utilization, prevents mixing from stacking as far as possible.And main sediments is mud in back segment tube settling mud accumulation area IV, natural-dehydration condition is poor, because its amount is less, can adopt whizzer or pressure filter dehydration, form mud cake, be convenient to comprehensive treating process.
