The utility model is characterized in that a housing is arranged outside the air float separating cylinder body, and a filtering layer is arranged between the air float separating cylinder and the housing. Three major techniques of air float, deposition and filtration are integrated into a whole, and the sewage after the primary treatment of the sewage purifying device can completely achieve the national and the local effluent standards. The utility model is suitable for the sewage treatment of industries such as electroplating, printing and dyeing, paper making, etc., and the entire device has the advantages of small floor area, low energy consumption and convenient operation.
Description
The utility model relates to the sewage purification technology field, particularly to the improvement of air supporting effluent treatment plant.
Existing air supporting effluent treatment plant is generally by air-dissolving apparatus, the dissolved air flotation cylindrical shell, mix cylinder, sludge bucket, mud-scraping machine, sump pumps etc. are partly formed, processed sewage tangentially enters mix cylinder by water inlet pipe after offeing medicine before sump pump, in cylindrical shell, mix the back and form quality less than 1 suspended layer with dissolved air water, through being installed in the mud-scraping machine at dissolved air flotation cylindrical shell top, sludge bucket is discharged, purify waste water and after dissolved air flotation cylindrical shell bottom water outlet enters annular collecting vat, discharge, though the sewage after the wherethrough reason obtains certain purification, but also can't reach country or local emission standard of working out, if it is up to standard, then also must with precipitation, filters and to wait other devices in series runnings, but what bring is that occupation area of equipment is big thereupon, investment is doubled and redoubled, the processing costs costliness, a series of problems such as operation easier increase are for general enterprise is difficult to bear.
The purpose of this utility model is to provide a kind of gas collection three big technology of floating, precipitate, filter to handle in the sewage purification of once just can finishing of one, reaches the high-effective sewage purifying device of country or local pollution exhaust criteria.
The utility model is achieved in that it comprises air-dissolving apparatus, dissolved air flotation cylindrical shell, mix cylinder, sludge bucket, mud-scraping machine, annular collecting vat, sump pump, it is characterized in that: the dissolved air flotation cylindrical shell is provided with shell outward, is provided with filtering layer between shell and dissolved air flotation cylindrical shell.
Back taper is adopted in dissolved air flotation cylindrical shell bottom, and its bottom water outlet is connected to down the width of cloth and penetrates water distributor.Be connected to the width of cloth on the annular collecting vat water-in and penetrate water distributor.Below filtering layer, be provided with the ring-like width of cloth and penetrate washpipe.
The utility model has formed the settling region and has been provided with filtering layer between the two at them owing to be provided with shell outside the dissolved air flotation cylindrical shell, thereby had precipitation and filtration, air supporting three big technical functionalitys, sewage after its primary treatment can reach country and local pollution exhaust criteria fully, and whole plant area area is little, low, the less investment of energy consumption, easy to operate.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is penetrated the structural representation of water distributor for the upper and lower width of cloth of the utility model.
Accompanying drawing 3 is penetrated the washpipe structural representation for the annular width of cloth of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
This device one-piece construction adopts garden column type awl end tube structure.Mix cylinder ［ 3 ］ is vertically fixed on the base plate ［ 13 ］, dissolved air flotation cylindrical shell ［ 2 ］ is fixed on the mix cylinder ［ 3 ］, the tube end of dissolved air flotation cylindrical shell ［ 2 ］ is a back taper, be evenly equipped with 6 water outlets at the bottom of it, the width of cloth is installed down on the water outlet penetrates water distributor ［ 7 ］, mud-scraping machine ［ 14 ］, sludge bucket ［ 15 ］ are arranged on dissolved air flotation cylindrical shell ［ 2 ］ top, are connected to shore pipe on the sludge bucket in order to discharging air supporting mud.Shell ［ 1 ］ is arranged on outside the dissolved air flotation cylindrical shell ［ 2 ］, be installed in one heart on the base plate ［ 13 ］ with mix cylinder ［ 3 ］, and by several piece gusset ［ 20 ］ reinforcement connection, upper fixed is installed prop ［ 16 ］ between shell ［ 1 ］ and dissolved air flotation cylindrical shell ［ 2 ］, on prop, place cyclic flushing pipe ［ 10 ］, the flushing water source is the water receiving source in addition, also can connect with injecting dissolve gas tower ［ 11 ］, provide by injecting dissolve gas tower ［ 11 ］, cyclic flushing pipe ［ 10 ］ upside offers two row's flushing through holes ［ 22 ］, it is 2mm that the utility model is got the flushing through-hole diameter, spacing 80mm, β=45 °.On prop, place the filtering layer ［ 6 ］ of the about 550～650mm of total thickness then, its material adopts φ 25, the cinder of the coke of φ 15 and φ 5～10, because of it has comparatively flourishing microvoid structure, not only can remove and hold back through the residual subparticle of air supporting post precipitation sewage, also have the decolouring function.Annular collecting vat ［ 4 ］ is fixedly installed on the filtering layer ［ 6 ］, is connected to the width of cloth on its water-in and penetrates water distributor ［ 8 ］; The downside that the upper and lower width of cloth is penetrated water distributor ［ 8,7 ］ is evenly equipped with two exhausting holes ［ 9 ］, through hole ［ 9 ］ and medullary ray preferably become α=45 °, the sectional area summation of this two exhausting hole ［ 9 ］ should be equal to or greater than or the following width of cloth is penetrated the water distributor sectional area, it is all even stable to be beneficial to current, prevent and reduce vortex phenomenon, improve decontamination effect improving.The injecting dissolve gas device is by injecting dissolve gas tower ［ 11 ］, under meter, ejector ［ 19 ］, water pump compositions such as ［ 18 ］, injecting dissolve gas tower ［ 11 ］ is connected in mix cylinder ［ 3 ］ bottom by dissolved air water releasing tube ［ 17 ］, is provided with an ejector ［ 12 ］ behind sump pump ［ 5 ］.Sewage forms good state of aggregation at the preceding adding coagulating agent of sump pump ［ 5 ］, ejector ［ 12 ］ behind sump pump ［ 5 ］ sucks the air dissolves of capacity behind water, tangentially enter mix cylinder ［ 3 ］ bottom, meet with dissolved air water and to mix from injecting dissolve gas tower ［ 11 ］, because bidirectional jet technical role, under the effect of microbubble, the formation quality floats rapidly to the top less than 1 suspended substance, through mud-scraping machine, sludge bucket is discharged, sewage behind primary purification width of cloth under dissolved air flotation cylindrical shell ［ 2 ］ bottom is penetrated water distributor ［ 7 ］ current-sharing and is entered between shell ［ 1 ］ and the dissolved air flotation cylindrical shell ［ 2 ］, quality fully is deposited in the bottom of shell ［ 1 ］ under action of gravity greater than 1 pollutent, discharge through mud discharging mouth ［ 21 ］, thereby finished secondary-cleaned, the filtering layer ［ 6 ］ on the sewage access arrangement top behind the secondary-cleaned, further obtained purification through Filtration Adsorption, reached purifying waste water of emission standard and penetrate water distributor ［ 8 ］ by the width of cloth on the top and flow into ring-like water leg ［ 4 ］ back and discharge.
