Specific embodiment
Be described further below technical solution of the present invention, but claimed range be not limited to it is described.
As shown in Figure 1, the present invention provides a kind of efficient dephosphorization techniques, comprising the following steps:
Step 1: the first flocculation reaction room, the second flocculation reaction room and mud chamber are provided, sewage is sequentially sent to the first wadding
Solidifying reaction chamber, the second flocculation reaction room and mud chamber, wherein put into flocculation aid into the first flocculation reaction room, and to first
Sewage within flocculation reaction room is stirred, and collects sludge side by side within the first flocculation reaction room, the second flocculation reaction room
Out, it is collected in the second flocculation reaction room and was sent into mud chamber after obtaining drainage；
Step 2: make to filter water sedimentation separation in mud chamber, sludge is collected in mud chamber and is discharged, while being precipitated
It is collected within room and obtains clear water；
Step 3: the first flocculation reaction will be sent into a part and step 1 in the sludge being collected into described in step 2
It is re-fed within the first flocculation reaction room after indoor sewage mixing.
Using technical solution of the present invention, combined by using three kinds of mechanical stirring, tube settling and flocculation methods
Water treatment technology, so that suspended matter is carried out efficient flocculating reaction after adding flocculation medicament, formed wadding body condense into compared with
Large particle precipitating, fine suspension is discharged after inclined tube further precipitates, in addition, also making finally to precipitate in the sludge being collected into
Part be recycled to again mixed within the first flocculation reaction room with original sewage after carry out flocculation sedimentation again, make in sewage
Suspended matter bigger particulate matter become by the condensation of the sludge of this part loopback effectively improve water outlet to sufficiently precipitate
Quality ensure that stable effluent quality.When raw water water, water quality, water temperature and hydraulic pressure change, flocculated using mechanical stirring
Mode, still be able to that there is preferable flocculation, sedimentation effect, keep water treatment efficiency more stable.Compared with common process, wadding
Solidifying precipitation reaction is abundant, is applicable in very much the processing of waste water of mine, after equipment water outlet is sterilized can direct reuse to underground conduct
Dedusting uses.This invention simplifies sewage treatment process, and sewage is made to have passed through sufficient flocculation sedimentation, and the sludge that will be collected into
It is recycled again, keeps sewage flocculation sedimentation effect more excellent, water treatment efficiency is more stable, when raw water water, water temperature
And hydraulic pressure still is able to have preferable flocculating effect when changing, and reduces water loss, improves outlet effect.

Sewage is that flows from above to below in the second flocculation reaction room.Tube settler is provided in the mud chamber, in step 2
It is described to make to filter water sedimentation separation in mud chamber, it is to make the filtered water stream through tube settler.It is filtered described in step 2
Water flows from bottom to top in mud chamber.Using the technical solution, make larger formed after flocculation sedimentation in this way
Grain object precipitates downwards since own wt is heavier, and the top crossed drainage and then float on flocculation reaction room after reaction, just
In being collected processing, also, sewage or flowing of the drainage in flocculation reaction room from bottom to top excessively, is conducive to increase in water and hang
The chance that floating object collides with each other makes it sufficiently be condensed into biggish particulate matter, and sewage or drainage excessively are compiled with even number
Number flocculation reaction room in flow from above to below, be conducive to be sequentially connected multiple flocculation reaction rooms, reduce equipment manufacturing costs.
Described in preferred steps three compared with the sludge part for being sent into the first flocculation reaction indoor sewage mixing step 2
Described in all sludge for being collected into mud chamber, quality accounting is 10%.Meanwhile in the sludge for making to be collected into
A part further includes putting into coagulant thereto during mixing with the feeding indoor sewage of the first flocculation reaction.Using the skill
Art scheme makes the sludge being collected into obtain reasonable application, and the part in sludge being collected into can flocculate instead with feeding first
It is re-fed into after answering indoor sewage to be sufficiently mixed in pipe-line mixer in the first flocculation reaction room, the partial sludge of loopback plays
The effect of enhancing flocculating effect, improves effluent characteristics.
Further, the sewage is 12min to 15min in the first flocculation reaction indoor residence time.In step 1
Described to be stirred to the indoor sewage of the first flocculation reaction, stirring intensity is the water for making the first flocculation reaction chamber interior walls edge
