(5) the inclined tube in clarification and effluent district can substitute with swash plate, but may not have the uniformity of water distribution of inclined tube good.
The sea water desaltination pre-treatment integrated apparatus of above-described embodiment, process explanation used is as follows:
(1) first, precipitation and air-float technology are the approximately uniform two kinds of techniques of cleaning principle and cleaning action.Conventionally " flocculation+precipitation " technique has extraordinary removal effect to turbidity, colloid, but more poor than the removal effect of the little material of seawater and dissolved organic matter matter to algae, oils isodensity." flocculation+air supporting " technique is very effective to algae, oils and organism; But in the time that the turbidity in former seawater is too high, the outlet effect of air flotation pool will be subject to serious impact.Especially not ideal enough to being subject to stormy waves, precipitation affects turbidity of sea water to change the decontamination effect improving of muddy coast seawater greatly; If run into, oil slick pollutes, eutrophication seriously causes the phenomenons such as alga eruption again, effluent quality after precipitation or air supporting worsens, filtration procedure will be born the water quality impact load of fluctuation, and the operation stability of purification process technique will face comparatively stern challenge.
(2) secondly, " flocculation+floating depositing pool " technique is the coupling technique of " precipitation and air supporting " two kinds of techniques, can solve the decontamination effect improving of polluted seawaters such as being subject to turbidity, oil slick, algae.But adopt top layer water outlet because traditional air-float technology adopts bottom water outlet, depositing technology, after coupling, floating depositing pool technique must adopt middle layer water outlet, so be difficult to a certain extent ensure out that water suspension long-term stability is in lower level.In addition, mixing process also needs independent configuration.
The different medias such as reuse waste water in seawater cleaning process again, (comprising: the supernatant liquor of concentrated, the dehydration of media filtration backwash water, chemical sludge etc.), backflow active sludge, chemical agent all need to enter into together with former seawater that coagulation basin front end mixes, flocculation reaction.Need to ensure the abundant mixing of each medium in coagulation basin; Reuse water is directly delivered to coagulation basin front end, avoids mixing and carrying out again second lift with former water before total inlet water lifting pumps.
(3) last, the severe corrosive of seawater is very large on the impact in work-ing life of the metal material submarine mechanical equipment such as the mechanical flocculation reaction agitator of tradition, settling tank (or settling pond) mud scraper.Ensureing, under the prerequisite of process function, to reduce the use of submarine mechanical equipment.
Sea water desaltination pre-treatment in the utility model the various embodiments described above is used in integrated apparatus, and the explanation of nouns of relevant technical terms is as follows:
(1) coagulation and coagulation basin: coagulation is divided into and mixes and two kinds of technological processs of flocculation.The process that the medicament dropping into is spread in rapidly in processed water equably to create sound response condition is called coagulation.The colloid that completes cohesion mutually collides, assembles under certain outer force-disturbance, is called flocculation with the process that forms larger cotton-shaped particle; Coagulation basin has been the device of mixing and flocculation process.
(2) precipitation and settling tank: under action of gravity, at the bottom of making in water cotton-shaped particle that the suspended matter heavier than water, flocculation generate etc. be precipitated to pond, realize a kind of water treatment process that particle separates with water and cry and precipitate.Settling tank has been the device of precipitation process.
(3) air supporting and air flotation pool: utilize and add a large amount of micro-bubbles in water, and it is sticked on algae, oils, cotton-shaped particle, common floating upward quickly is to the water surface with it, realizes a kind of water treatment process that particle separates with water air supporting.Air flotation pool has been the device of air supporting process.
(4) filter: cry filtration by a kind of water treatment process of foreign material in granulated material or porous medium amputation water.General media filtration or the ultrafiltration membrance filters such as sand filtration/hard coal of adopting in seawater cleaning treatment process.
Finally it should be noted that: the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement.All within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
