Embodiment Construction
[0018] Combine below image 3 and Figure 4 , the present invention is further described:
[0019] A settling tank for iron concentrate slurry sewage treatment, comprising a settling tank 1, a sewage inlet 4 and a sewage outlet 4 are arranged at both ends of the settling tank 1, and a plurality of water retaining walls 3 are provided in the settling tank 1 to deposit The pool 1 is divided into multiple sedimentation units, and a layer of cutoff wall 6 is built on the retaining wall 3. One end of the cutoff wall 6 is connected to the wall of the sedimentation tank 1, and the other end forms a water outlet 8 with the wall of the sedimentation tank 1. The distance between two adjacent water outlets 8 is the longest.
[0020] The function of the water retaining wall is: first, to block the solid material from flowing with the water to make it settle better; second, to allow more material to settle in the first small pool for easy collection.
[0021] The volumes of the multiple...

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 [0001] The invention relates to a settling pond, in particular to a settling pond for treating iron concentrate slurry sewage. Background technique [0002] The sewage treatment link that will be generated during the dehydration of the iron concentrate slurry, the existing treatment method will use the sedimentation tank, the traditional sedimentation tank structure is as follows figure 1 As shown, it includes a sedimentation tank 1, a water retaining wall 3, a sewage inlet 2 and a sewage overflow 4, wherein the height of the water retaining wall 3 is lower than that of the sedimentation tank 1 wall. like figure 2 As shown, the original water flow direction 5 flows in from the upper left corner of the sedimentation tank 1, and flows out from the overflow port of the lower right corner of the sedimentation tank 1 after sedimentation. [0003] It can be seen that although the sedimentation tank of the traditional structure is provided with a water retaining ...
