Description

High load capacity cyclone sediment depositing reservoir

Technical field:

The utility model relates generally to the device of water treatment, relates in particular to a kind of settling pond.

Background technology:

At present, in water treatment procedure, generally all use independently sedimentation basin or depositing reservoir, or utilize the depositing reservoir of microorganism or graphite powder to carry out water purification, it is by filter or use some chemical substances to impel the contamination precipitation in the water to be clean and make its separation, the general structure of the employed equipment of these methods is more complicated all, and not only investment is high and power consumption is big.Because the difficult control of sludge volume, cause excessive spoil disposal or because problem such as water distribution is irregular influences effluent quality through regular meeting.

Summary of the invention:

The purpose of this utility model is to avoid the deficiencies in the prior art part and a kind of high load capacity cyclone sediment depositing reservoir is provided, its compact conformation, and floor space is little, construction investment is economized, and body refuse refluxes, and water distribution is even, realize secondary separation, the settling pond that the upflow velocity of water is high.

The purpose of this utility model can be by realizing by the following technical solutions: a kind of high load capacity cyclone sediment depositing reservoir, include water inlet pipe (1), outlet pipe (12), honeycomb inclined-tube (9), being characterized in also including water inlet pipe (1) is arranged in the eddy flow desilting device (2), most of silt particle is separated from water, be the mud-water separation first time; Reaction container (3) is connected in outside the eddy flow desilting device (2), and current carry out the oxidized coagulated contact precipitation of medicament in reaction container (3) separates, and is the mud-water separation second time.Its reaction container (3) is connected with aqueduct (4), is provided with water-locator (5) in the exit of aqueduct (4), and current are distributed uniformly.Water-locator (5) is connected with transition settling zone (15) by sparge pipe (6) and perforation sparge pipe (7), in transition settling zone (15), be provided with honeycomb inclined-tube (9), be provided with triangle effluent weir (10) in the clear water zone (16) of honeycomb inclined-tube (9) top, triangle effluent weir (10) is connected with outlet pipe (12).

Described high load capacity cyclone sediment depositing reservoir, described reaction container (3) inside also is provided with annular discharge pipeline (8), and annular discharge pipeline has the hole on (8), and pore size distribution can fully be discharged the materials of separating such as silt at pipe up and down.Annular discharge pipeline (8) is connected with discharge pipeline (11), and discharge pipeline (11) is connected with water inlet pipe (1) by active sludge return duct (13) and screw pump (14) again.Active sludge return duct (13) can play at the muddy water of discharging through mud-water separation for the first time and helps the effect of coagulating entering water in the pond, also can add the input of flocculation medicament, and silt particle and the easy precipitation separation of impurity in the former water are come out.

Described high load capacity cyclone sediment depositing reservoir, described swirling flow sand-settling device (2) is the cone that the bottom is provided with opening, discharge from opening from materials such as the isolated silts of swirling flow sand-settling device (2), below opening, be provided with mud awl (17), mud awl (17) has the angle of inclination of 35-50 degree, can prevent the deposition of silt at the bottom of the pond.

The beneficial effects of the utility model are: body refuse refluxes, water distribution is even, realize secondary separation, in the water treatment procedure, make the total coconversion of water (flow) direction 4 times, add the oxidized coagulated contact precipitation of cyclone sediment and medicament, thereby make the silt particle in the former water be separated removal with various impurity, thereby obtain the effluent quality of turbidity below 10NTU, pass through the honeycomb inclined-tube precipitation process again, delivery turbidity can reach below the 3NTU.Upflow velocity is up to (it is high promptly to handle load) 2mm/s, so the advantage of the high load capacity disposal ability of innovative technology of the present utility model clearly can also be saved the area.
