Description

A kind of water treatment clarifying plant
Technical field
A kind of water treatment clarifying plant relates to the water treatment clarification technique, especially relates to the water treatment device that is used for removing water insoluble material, as: the water treatment device of removing suspended matter and oils.
Background technology
In existing water treatment, adopt make a return journey insoluble substance in dewatering of single gravitational settling method or dissolved air flotation usually, as: suspended matter and oils.For example, the settling tank of conventional municipal sewage plant is with regard to make a return journey suspended solids in dewatering of the method that is based on gravitational settling.This class settling tank can be removed heavier suspended solids (density is much larger than the solid of 1 grams per milliliter) soon, yet, for the less and little suspended solids of density or oils (density less than or approach the insoluble substance of 1 grams per milliliter), just be difficult to maybe can not remove with settling tank.As everyone knows, contain usually in water and the waste water the different insoluble substance of density (from less than 1 grams per milliliter to greater than 1 grams per milliliter).Because the bigger insoluble substance of density can at first sedimentation in settling tank, the just more and more difficult sedimentation of remaining insoluble substance, the speed that the total insoluble substance of water treatment is removed can be in time more and more lower, therefore, single intermediate processing is only adopted in water treatment, it is only effective to removing heavier insoluble substance, and can not effectively remove all insoluble substances, especially the less insoluble substance of those density.
Adopt the insoluble substance in the dissolved air flotation removal water, this method needs the high density dissolved air water is imported in institute's water to be processed continuously, enters the dissolved air flotation pond after mixing.Because the gas in the high density dissolved air water can discharge gradually with the form of microbubble after decompression, these microbubbles can be attached on the surface of insoluble substance (suspended solids and elaioleucite), make the insoluble substance come-up and are retained in the surface of dissolved air flotation pool inner water.The air supporting mud of having assembled (being scum silica frost) is removed by overflow or with slag scraper usually, thereby makes water to be processed obtain clarification.Dissolved air flotation can be removed less suspended solids and the oils of density in the water well.Yet, owing to contain the insoluble substance of different densities in the water, even the bigger suspended solids of some density can not float under the help of micro bubble, but can be with sink to the pond than original slower speed at the bottom of; Some was easy to the material removed through free setting originally, became on the contrary under the effect of micro bubble and can not precipitate and can not float, and therefore can be retained in the water outlet.That is to say that dissolved air flotation has hindered the removal of the bigger insoluble substance of density.Therefore, water treatment adopts single dissolved-air air-float method can not remove all insoluble substances effectively, the bigger insoluble substance of those density especially, and it can only effectively remove less suspended solids of density and oils.
Summary of the invention
Usually contain the different insoluble substance of multiple density in water and the waste water, in the ideal case, the solid that density is big needs to remove with the precipitator method, and less suspended solids and the oils of density needs remove with dissolved air flotation.Yet, in existing engineering practice, only adopt single method usually, or adopt the insoluble substance in gravitational settling method or the employing dissolved air flotation removal water.In order to overcome the deficiency of existing treatment process to the water that contains suspended solids and oils, the present invention proposes and a kind ofly gravitational settling is removed in the water insoluble substance and air-dissolving air-float remove that insoluble substance organically combines in the water, make full use of precipitation and pneumatically supported effect, with more effective and remove the suspended solids in the water and the water treatment clarifying plant of oils apace.
The present invention is by a gravity settling chamber that is used to remove the bigger suspended solids of density, an air-dissolving air-float separate chamber that is used to remove less suspended solids of density and/or oils, and and air-dissolving apparatus, captation and water-level control apparatus constitute together.Water inlet pipe is located at gravity settling chamber's sidepiece, and the water-in of water inlet pipe can be located at an indoor middle part of gravitational settling or a side.At the indoor snubber assembly that is provided with of gravitational settling, passed through aquaporin between gravity settling chamber and the air-dissolving air-float separate chamber and be communicated with, cross and in the aquaporin mixing apparatus can be set or directly will cross aquaporin and make and promote gas, the mixed structure of water.Captation is communicated with air-dissolving apparatus and water-level control apparatus respectively by pipe connecting; The water-in of air-dissolving apparatus is communicated with captation, and from captation water inlet, the water outlet of air-dissolving apparatus is communicated with the aquaporin of crossing between gravity settling chamber and the air-dissolving air-float separate chamber by pipe connecting, to aquaporin water outlet excessively.In water treatment procedure, the water that contains suspended solids and/or oils at first enters the settling chamber, through reducing the turbulent fluctuation degree of water inlet behind the snubber assembly, makes the bigger solid of density sink at the bottom of the pond in a short period of time rapidly and is excluded.In the top tiltable of the indoor water-in of gravitational settling or flow deflector or thrust-augmenting nozzle vertically are set, the turbulent fluctuation degree with further reduction water inlet improves removal effect.The high density dissolved air water that is produced by air-dissolving apparatus imports crossing in the aquaporin between connection gravity settling chamber and the air-dissolving air-float separate chamber, contact, mix with the water that contains less suspended solids of density and/or oils after the process precipitation process, enter the gas-floating chamber separation then and carry out solid-liquid separation.Gas in dissolved air water form with microbubble after being decompressed to normal pressure discharges, these microbubbles are attached on the surface of suspended solids and olesome, make suspended solids and oils the come-up or stably rest on the water surface of gas-floating chamber, form air supporting sludge blanket (scum silica frost), after being accumulated to a certain degree, these air supporting mud are discharged automatically or are struck off by the mechanical curettage device via the scum silica frost outlet.Be provided with in water-level control apparatus and regulate weir plate and rising pipe, be used to control the indoor water level of dissolved air flotation, treated water is collected after water-level control apparatus is discharged from rising pipe via captation.
If in water treatment procedure, need add chemical agent such as coagulating agent and/or flocculation agent, on the water inlet pipe of apparatus of the present invention, a motionless mixer can be installed, chemical agent filling at the front end of motionless mixer so that mixed fully at the mixer place with water, entering device of the present invention then clarifies, in this case, the gravity settling chamber has the function of flocculating chamber simultaneously concurrently, can further improve the effect of water treatment.
Characteristics of the present invention are: the water treatment clarifying plant is by the gravity settling chamber of removing the big suspended solids of density and remove the little suspended solids of density and/or the air flotation separating chamber organic combination of oils is integral, and and air-dissolving apparatus, captation, water-level control apparatus constitutes together, its compact construction, rationally, volume is little, it not only given full play to gravitational settling and air-dissolving air-float water treatment effect and can replenish mutually, therefore, water treatment device of the present invention carries out water treatment than single gravitational settling method of existing employing or dissolved-air air-float method, can more effectively remove the insoluble material in the water.Because air flotation separating chamber of the present invention only is used for less suspended solids of partition density and/or oils, solid therefore needed gas/lower than understanding, thus reduced the energy consumption that is used to make the high density dissolved air water.In device of the present invention, heavy solid can be removed rapidly in the gravity settling chamber, and simultaneously light solid and/or oils can be removed rapidly in gas-floating chamber, and therefore total treatment time of water is less than traditional settling tank or air flotation pool, and water treatment is effective.
