Abstract
The invention relates to inclined plate sedimentation equipment. In a sedimentation process applied in the field of water treatment, after an inclined plate sedimentation tank and an inclined plate sedimentation tank with small spacings operate for a period of time or when the water quality and the water volume are changed, sedimentation efficiency and effluent quality of the inclined plate sedimentation tank and the inclined plate sedimentation tank with small spacings are obviously reduced so as to cause serious mud accumulation and blockage between inclined pipes and inclined plates, even collapse of the inclined pipes and the inclined plates. A bidirectional flow variable-spacing inclined plate sedimentation tank comprises a bidirectional flow sedimentation tank, wherein the bidirectional flow sedimentation tank is divided into two parts by a guide wall; a first part is a same-way flow large particle sedimentation region; an included angle between each inclined plate and the horizontal plane in the same-way flow large particle sedimentation region is 45 degrees to 60 degrees; a second part is a reverse flow small particle sedimentation region; an included angle between each inclined plate and the horizontal plane in the reverse flow small particle sedimentation region is 55 degrees to 70 degrees; spacings between the inclined plates in the two sedimentation regions are different; the second part of the bidirectional flow sedimentation tank is provided with a water collecting tank; the tail end of the water collecting tank is provided with a water outlet pipe; and a sedimented sludge hopper and a sludge pipe are arranged on the lower surface of the bidirectional flow sedimentation tank. According to the invention, large and small particles are regionally sedimented, so that the problem of blockage between the inclined plates is avoided and sedimentation efficiency is high.
Description
Technical field:
The invention belongs to the water treatment facilities technical field, relate to a kind of improvement of water treatment swash plate equipment.
Background technology:
China is extensive use of rectangular sedimentation tank in recent decades.Traditional horizontal sedimentation tank simple structure is easy to operate, and it is more safe and reliable to work, and the operation and management level of requirement is lower; But floor space is big, and treatment effeciency is low, wants to reduce the length that the turbidity of filtering preceding water will increase sedimentation basin significantly.After the seventies, China various places water factory has generally used tube settler, and deposition efficiency has obtained increasing substantially.But through using decades, its reliability can not show a candle to horizontal flow basin.This mainly is that the irrationality of tube settling equipment self structure causes.The tradition sedimentation theory thinks that current are in laminar condition in swash plate, the tube settler.Actually this is not so, in fact current are pulsed in tube settler, this be because in the inclined tube big alumina blossom particles in precipitation with the water generates relative motion, can produce micro cyclone in the alumina blossom particles back, the generation of these vortexs and motion have caused the pulsation of current.These pulsation do not have any influence for the precipitation of big alumina blossom particles, have played the jacking effect for the incomplete short grained precipitation of reaction, so just influenced effluent quality yet.In order to overcome this phenomenon, suppress the pulsation of current, and invented little spacing sloping plate deposition equipment, compare with inclined tube and improved deposition condition significantly.Little spacing inclined-plate clarifying basin has demonstrated fully the advantage in shallow pond, and deposition efficiency is very high, and the spacing of swash plate is more little, and deposition efficiency is more high.But in practical application in recent years, little spacing inclined-plate clarifying basin is after operation a period of time, and perhaps when water quality and quantity changed, its deposition efficiency and effluent quality obviously descended, and causes serious deposition and obstruction between swash plate, even presses the swash plate that collapses.This problem has caused its application limit.The horizontal tube sedimentation basin in addition of new development at present.Its common structure is rectangle, and assembling can not form triangle yet and cross the water dead band in rectangle form pool, has improved the utilization rate that the pond holds.The horizontal tube sedimentation basin has the major advantage of rectangular sedimentation tank, stable operation, and capacity of resisting impact load is strong, and operating flexibility is big, and delivery turbidity is low, is at present near the sedimentation of " shallow pool theory ".Water is bottom horizontal flow sheet in horizontal tube, the suspended particulate gravitate vertically sinks, and slips into the slip road from mud discharging mouth after at the bottom of the pipe that suspended particulate exposure level pipe is 60 °, and muddy water separates immediately, mud is very fast falls into the mud district from the slip road, solves " shallow pool theory " spoil disposal difficult problem effectively.But it constructs relative complex.
Summary of the invention:
In order to address the above problem, the invention provides a kind of two-way rheology spacing inclined-plate clarifying basin, comprising: bidirectional flow sedimentation basin (1), discharge pipeline (2), water leg (3), outlet pipe (4), precipitation bucket (5), the big spacing swash plate of concurrent (6), the little spacing swash plate of reverse flow (7), dowel (8), training wall (9), water hole hole (10); It can effectively improve sedimentation basin efficient, guarantee that spoil disposal is smooth and easy.
In sedimentation basin, when horizontal flow velocity was certain, the time of staying of water in sedimentation basin was certain.Owing to the gravity effect, oarse-grained material sinks very fast like this, and short grained material sinks slower.Therefore can produce a kind of phenomenon, mainly be the bulky grain sediment in the sedimentation basin front portion, mainly is the granule sediment at the sedimentation basin rear portion.In conjunction with the susceptible to plugging problem of little spacing sloping plate deposition equipment.Sedimentation basin will be divided into two parts by one section training wall among the present invention.The bulky grain settling zone is big spacing sloping plate deposition equipment, and the swash plate spacing is 60-150mm, and setting angle is 45 °-60 °, and large particulate matter mainly precipitates in this section; The granule settling zone is little spacing settling apparatus, and the swash plate spacing is 15-50mm, and setting angle is 55 °-70 °, and finely ground particle substance is precipitation in this section mainly, the blockage problem that also can avoid simultaneously the precipitation because of large particulate matter to cause.
Because the effect of training wall is divided into two parts with sedimentation basin, at bulky grain settling zone water and mud concurrent (current from up to down), in granule settling zone water and mud reverse flow (current from bottom to top), desilting area and deposition efficiency all have remarkable increase.After sedimentation basin is divided into two parts, can make the particulate matter subregion carry out sedimentation, not only avoid the obstruction of swash plate equipment but also can reach sedimentation effect efficiently.
Beneficial effect of the present invention:
(1) pool-type structure optimization.Training wall is set sedimentation basin is divided into two sections, and make swash plate equipment transfer little spacing to by big spacing, effectively avoided blocking problem.
(2) deposition efficiency height.Handle water among the present invention through twice precipitation, desilting area and time effectively improve, and deposition efficiency is corresponding raising also.
