Abstract
The invention discloses a short-time flocculation and high speed sedimentation sewage treatment device, which belongs to the technical field of sewage treatment. Floccus sedimentation is accelerated under the action of an additional magnetic field, so that the aim of effectively and quickly treating is fulfilled. The device consists of a water inlet pipe, a pipeline mixer, a flocculating agent adding port, a quick stirring paddle, a rectangular water outlet, a baffle plate, a slow stirring paddle, a circular water outlet, a magnet accommodating platform, a strong magnet, a mud pipe, a control valve, a magnetic separator, a spiral conveying pipe, an outlet baffle plate and a water outlet pipe. Sewage passes through the pipeline mixer, reaches a quick stirring region, is mixed for reaction under the actions of the quick stirring paddle and the slow stirring paddle and quickly sediments under the action of the strong magnet, so that the aims of treating and purifying are fulfilled. The device has the advantages of simple structure, low construction cost, high handling capacity and short treatment time, and is suitable for quickly treating a large amount of overflowing sewage.
Description
Technical field
The invention belongs to technical field of sewage, specifically, it relates to a kind for the treatment of device for overflow sewage, is used for fast processing and the purification of overflow sewage.
Background technology
Along with the quickening of urbanization process, the Builtup areas area constantly enlarges, and causes Permeable stratum area to increase considerably, and causes under identical condition of raining, and runoff coefficient increases, and flood peak shifts to an earlier date, and magnanimity increases, and municipal drainage and river course flood are consisted of huge pressure.In rainfall, rainwater and the formed runoff urban ground of flowing through washes away, has assembled a series of pollutents, cause in overflow sewage pollutant load high, change large, complicated components, overflow sewage directly discharges water body without any processing, and urban water-body is caused severe contamination.Again because pollution load of overflow produced in the rainy day, therefore that its discharging has intermittence, emergentness, randomness and instantaneous quantity discharged is larger, this has caused very large difficulty [2 for the processing of urban runoff pollutent, 3], therefore, exploitation one cover starts fast, processes the technique that load is high and water-fast power is impacted.
Domestic is being that blank has had the commercialization treatment unit of many sleeve formings abroad substantially aspect the processing of combined sewerage overflow, the techniques such as main Densadeg, Actiflo, Lamella Clarifier, these stream rainwater treatment devices have been accepted theoretical to coagulation classical in water treatment on guiding theory, it is perfect, as not depend on a storage pond coagulating sedimentation processing unit, but still exist flocculant dosage large, sludge output is large, the shortcomings such as processing cost height.
Summary of the invention
The object of the present invention is to provide the algae-removing devices that a kind for the treatment of time is short, running cost low and can realize processing in a large number.
For achieving the above object, the present invention is comprised of rapid stirring district, low rate mixing district and three of settling regions part, comprises water inlet pipe, line mixer, flocculant concentration mouth, rapid stirring oar, the rectangle mouth of a river, baffle plate, low rate mixing oar, circular water outlet, magnet mounting table, strong magnet, shore pipe, control valve, magnetic separator, spiral conveying tube, outlet damper, rising pipe.Water inlet pipe is positioned at bottom of device, is provided with line mixer between water inlet pipe and rapid stirring district; Connect the flocculant concentration mouth above line mixer; Be provided with the rapid stirring oar in the rapid stirring district, between rapid stirring district and low rate mixing district, the rectangle water outlet is established on the top of dividing plate, and the top of low rate mixing district rectangle water outlet one side is baffled, and the low rate mixing oar is established in the centre; Between low rate mixing district and settling region, circular water outlet is established on dividing plate top, and its position is slightly lower than rectangle water outlet; 45 degree swash plates are established in settling region bottom, and drawer-like magnet mounting table is established in the swash plate bottom, and the above places strong magnet; The top of water outlet one side of settling region sets out the water baffle plate, and height of baffle plate is 2/3rds of settling region, and water outlet connects rising pipe, and its position is slightly lower than the circular water outlet in low rate mixing district; The bottom, settling region connects shore pipe, and shore pipe connects magnetic separator, between shore pipe and magnetic separator, control valve is set; Magnetic separator is connected with the flocculant concentration mouth by spiral conveying tube.
When using this device, overflow sewage with certain pressure is entered by water inlet pipe, at first in line mixer and magnetic kind and flocculation agent mix, enter afterwards rapid stirring district and low rate mixing district enhanced coagulation effect, then enter the settling region, sedimentation rapidly under the effect of strong magnet.When settling region mud is piled up to a certain extent, open control valve, the magnetic kind in mud is separated by magnetic separator, and is transported to the flocculant concentration mouth by spiral conveying tube, realizes the reuse of magnetic kind.
Beneficial effect of the present invention is that arranging of strong magnet realized the flco rapid subsidence, reaches the purpose of a large amount of fast processing.The present invention is simple in structure, and laid down cost is low, and floor space is little, can realize the efficient processing of overflow sewage.
