Description

A kind of depositing reservoir

Technical field

The utility model relates to a kind of water treatment facilities of giving, and specifically is meant a kind of feed water treatment reservoir.

Background technology

In order to adapt to the needs in market,, carry out modularization, combined type construction in order to be adapted to Large Water Works; Save floor occupying area; Reduce pond body height on the ground, the conserve energy loss; On the basis of novel depositing reservoir, developed into the depositing reservoir of present technique.

The utility model content

The technical problems to be solved in the utility model is the defective that overcomes prior art, provides a kind of energy consumption depositing reservoir low, applied widely.

In order to solve the problems of the technologies described above, the utility model provides following technical scheme:

A kind of depositing reservoir comprises the annular external cell body of arranging from outside to inside, annular urceolus and interior middle tube, and annular external cell body is around annular urceolus, and interior middle tube is positioned at the center of depositing reservoir; In the annular urceolus, a side of bottom and close interior middle tube is provided with deflector, and the space between side deflector and the outer tube side wall is the water conservancy diversion district, and the space between baffle at bottom and the urceolus diapire is suspension body refuse district, and water conservancy diversion district and suspension body refuse district communicate; The annular urceolus in, establish settling section around deflector, settling section communicates with the top in suspension body refuse district; Tube is established hybrid reaction district, settling zone and enrichment region in interior, and this three district connects connection from top to down; Wherein, the hybrid reaction district is cylindrical, and it is trapezoidal that the settling zone is, and it is trapezoidal that enrichment region is, and the taper settling section of urceolus lower end and the trapezoidal settling zone in hybrid reaction district coincide adjacent; The enrichment region upper end open is in the water conservancy diversion district; Water inlet pipe is connected with the hybrid reaction district; Discharge pipeline is connected with suspension body refuse district, enrichment region.

Further, the outer tube bottom of annular is tapered, and the side deflector tilts 45 °, and baffle at bottom tilts 50 °～60 °, and the three forms conical suspended body refuse district.The discharge pipeline that connects suspension body refuse district is 45 ° of placements, and the mouth of pipe is positioned at the bottom in suspension body refuse district.

Mechanism is:

(1) coagulant through pipe-line mixer with after former water fully mixes, in entering along the tangent line eddy flow in tube, mix in the hybrid reaction district.Look raw water turbidity and determine whether to add flocculation aid (polyacrylamide); The part suspension that enters is through after the hybrid reaction, in the settling zone, enrichment region finishes precipitate and separate.

(2) overflow on the tube top in interior of the mixing water after eddy flow is finished in the settling zone, enters the mix suspending district behind the deflector fluid stable, diminishes gradually with cross-section of river increase, flow velocity, and flco is finished growth in this process;

(3) mixing water goes out the water conservancy diversion district and enters sludge suspension district, the outside, and the floating zone is that training wall, deflector, the umbrella shape plate by 50 °～60 ° of the skew walls on 45 ° on bottom concentration zone top, separation chamber constitutes the awl end formula body refuse zone that suspends, and finishes contact flocculation in this zone.

(4) after current enter settling section, die-off, hold the flco mixing water under the arm and finish Separation of Solid and Liquid at this because of upflow velocity.

(5) set up inclined tube on settling section top, further control remaining flco in the water.Observation shows that inclined tube can play the rising expansion of stable suspersion slime layer and the contact flocculation effect that promotes and strengthen the suspension slime layer.

(6) depositing reservoir bottom, interior middle tube are to divide into 45 ° of cone buckets, and discharge pipeline is established in the bottom, because hydrostatic pressing is powerful, when opening bottom and mud valve, produces very high flow velocity, makes the very unobstructed discharge of mud.45 ° mud-removing bucket angle helps flowing of heavy mud, and simultaneously, suction that water produces when revolving stirring and spoil disposal and stirring all are spoil disposal reasons smoothly.

The beneficial effect of the utility model technology is: the shape of (1) pond body, roundly become squarely by original, and make the pond physical efficiency better make up; (2) angle of tube conical section changes in, and an interior middle tube straight section partly extends, and has increased the reaction time; (3) discharge pipeline at bottom and middle part has adopted the siphon spoil disposal, and is rationally distributed; (4) area of pond body has increased by 25%, and handling the water yield has increased by 25%.(5) the whole system floor space saves 10%.
