Abstract
The invention relates to a sewage treatment settling pond for iron ore concentrate slurry. The sewage treatment settling pond comprises a settling pond, wherein a sewage inlet and a sewage outlet are formed at two ends of the settling pond; a plurality of water retaining walls are arranged in the settling pond in a heightened mode to divide the settling pond into a plurality of precipitation units; a layer of water interception wall is additionally built on each water retaining wall; one end of the water interception walls are connected with the wall of the settling pond, and the other end of the water interception walls and the wall of the settling pond form water passing openings; and the distance between any two adjacent water passing openings is the longest. In the sewage treatment settling pond, the wall in the middle of the settling pond is heightened partially to change the water flow direction and increase a water flow path by over one time, so that the settling time of sewage can be improved effectively to improve the settling efficiency of the sewage greatly.
Description
Technical field
The present invention relates to a kind of sedimentation basin, especially relate to a kind of iron ore concentrate slurry sedimentation basin of sewage disposal.
Background technology
The sewage disposal link that the iron ore concentrate slurry can produce when the dehydration link; Can use sedimentation basin in the existing processing method; Traditional sedimentation basin structure as shown in Figure 1; Comprising sedimentation basin 1, waterwall 3, sewage import 2 and sewage overflow mouth 4, wherein the height of waterwall 3 is lower than sedimentation basin 1 pool wall height.As shown in Figure 2, it is to flow into from the upper left corner of sedimentation basin 1 that current originally move towards 5, flows out through the overfall of deposition from sedimentation basin 1 lower right corner.
This shows that though the sedimentation basin of traditional structure is provided with waterwall 3 in the pond, waterwall 3 stops that not playing optimal effectiveness prolongs sewage time of staying in sedimentation basin.In addition, because size is identical, make most of precipitate in a plurality of precipitation unit in the independently precipitation unit that waterwall 3 and sedimentation basin 1 formed, bring inconvenience, increased a large amount of production costs for collecting, handle and dig out in the future.
Summary of the invention
The present invention has designed a kind of iron ore concentrate slurry sedimentation basin of sewage disposal, and the technical problem of its solution is that existing sedimentation basin structure fails to improve greatly deposition efficiency and the precipitate distribution inequality is unfavorable for removing.
In order to solve the technical problem of above-mentioned existence, the present invention has adopted following scheme:
A kind of iron ore concentrate slurry sedimentation basin of sewage disposal; Comprise sedimentation basin (1), be distributed with sewage import (4) and outlet of sewer (4) at said sedimentation basin (1) two ends; In said sedimentation basin (1), improve and be provided with polylith waterwall (3) sedimentation basin (1) is divided into a plurality of precipitation unit; It is characterized in that: on said waterwall (3), add and build one deck water stop (6); Said water stop (6) one ends are connected with said sedimentation basin (1) pool wall; The other end and said sedimentation basin (1) pool wall form outlet pass (8), and the distance between any two adjacent outlet passes (8) is for the longest.
Further, a plurality of precipitation unit volumes between said sewage import (4) and the said outlet of sewer (4) reduce successively.
Further, the precipitation unit body volume that is positioned at of said sewage import (4) accounts for more than 1/3rd of whole said sedimentation basin (1).
This iron ore concentrate slurry sedimentation basin of sewage disposal is compared with traditional sedimentation basin, has following beneficial effect:
(1) the present invention adds one section water stop of block on original waterwall; The direction that block changes current that adds through water stop; Make water (flow) direction by original be that the oblique line of end points flows to water inlet and delivery port; Changing into broken line flows to; So just make the approach of current increase by one times; Be that sewage has increased by one times in the sedimentation time of sedimentation basin, improved deposition efficiency greatly.
(2) the present invention is through calculating effluent flow rate and iron ore concentrate settling velocity; Thereby confirm the volume of the precipitation unit that the sewage import is positioned at; Make the iron ore concentrate major part be deposited in the precipitation unit that the sewage import is arranged in, be convenient to dig in the future fortune and remove the iron ore concentrate sediment.

The specific embodiment
Below in conjunction with Fig. 3 and Fig. 4, the present invention is further specified:
A kind of iron ore concentrate slurry sedimentation basin of sewage disposal; Comprise sedimentation basin 1, be distributed with sewage import 4 and outlet of sewer 4 at sedimentation basin 1 two ends; In sedimentation basin 1, improve and be provided with polylith waterwall 3 sedimentation basin 1 is divided into a plurality of precipitation unit; On waterwall 3, add and build one deck water stop 6; Water stop 6 one ends are connected with sedimentation basin 1 pool wall; The other end and sedimentation basin 1 pool wall form outlet pass 8, and the distance between any two adjacent outlet passes 8 is for the longest.
The effect of waterwall is: the first, the blocking-up solid material is along with flow makes its better deposition; The second, allow in more material has been deposited in first little pond convenient the collection.
A plurality of precipitation unit volumes between sewage import 4 and the outlet of sewer 4 reduce successively.Specifically, the precipitation unit body volume that is positioned at of sewage import 4 accounts for more than 1/3rd of whole sedimentation basin 1.
On waterwall 3, add and build one deck water stop 6, only need on original waterwall 3, add with cement and brick as shown in Figure 3 and build the high wall of 15CM, assurance water can not flow through and get final product, and outlet pass 8 length of reserving are 2M.After such transformation, changed the trend of current, so just make the approach of current increase by one times, promptly sewage has increased by one times in the sedimentation time of sedimentation basin, has improved deposition efficiency greatly.
Combine accompanying drawing that the present invention has been carried out exemplary description above; Obvious realization of the present invention is not subjected to the restriction of aforesaid way; As long as the various improvement of having adopted method design of the present invention and technical scheme to carry out; Or design of the present invention and technical scheme are directly applied to other occasion without improving, all in protection scope of the present invention.
