Description
Technical Field
The utility model relates to a sewage treatment field, specifically speaking, the utility model relates to a prevent two heavy pond activated sludge along with device of water loss.
Background
The main effect of the secondary sedimentation tank of the phenol-cyanogen sewage treatment station in the coking enterprise is to carry out mud-water separation, the sludge is not smoothly discharged due to the abnormal operation of a sludge dewatering device, the backflow sludge amount is not adjusted, the retention time is long, the sludge dead angle at the bottom of the secondary sedimentation tank is not collected by a sludge scraper, and the like, so that the sludge denitrification reaction is released to generate gas or sludge to float upwards, and the COD in the secondary sedimentation tank is increased due to the increase of suspended solids in the effluent of the secondary sedimentation tank, and also due to the reduction of the sludge concentration of a biochemical system.
Disclosure of Invention
The utility model aims to solve the technical problem that a device that can be quick, effectual will float and break up, subside and prevent to subside the in-process along with water loss at the mud on two heavy pond surfaces is provided.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the utility model provides a prevent device that two heavy pond activated sludge runs off along with water, includes two heavy ponds, peripheral transmission mud scraper working bridge, water-collecting weir, spray set and fender, peripheral transmission mud scraper working bridge is installed on the pool face in two heavy ponds, and one side at peripheral transmission mud scraper working bridge is fixed to angle steel for the spray set, and the water-collecting weir links to each other with two heavy ponds, and the fender is fixed on the water-collecting weir.
Preferably, the spraying device comprises a spraying pipeline and a water pump, the spraying pipeline is arranged on one side face of the peripheral transmission mud scraper working bridge and is provided with a hole, the spraying pipeline is connected with the water pump, the water pump is placed below the water surface of the secondary sedimentation tank, and clear liquid in the secondary sedimentation tank is directly extracted for pressurization spraying.
Preferably, the mud guard is connected with a water collecting weir of the secondary sedimentation tank, the highest point of the mud guard is horizontal to the water collecting weir, and the lowest point of the mud guard extends 500mm below the water surface.
Adopt the technical scheme of the utility model, can obtain following beneficial effect:
the utility model discloses prevent that two from sinking pond activated sludge along with water loss's device simple structure, be convenient for maintain, can effectually hold back the activated sludge on two heavy pond surfaces, prevent because of mud along with water loss, influence two heavy pond play water quality of water and good oxygen pond sludge concentration.
Drawings
The contents of the description and the references in the drawings are briefly described as follows:
FIG. 1 is a schematic structural view of the apparatus;
the labels in the above figures are: 1. a secondary sedimentation tank; 2. a peripheral transmission mud scraper working bridge; 3. a water collection weir; 4. a spraying device; 5. a fender is provided.
Detailed Description
The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings, in which the shapes, structures, mutual positions and connection relationships of the respective members, the functions of the respective portions, the operation principles, and the like of the respective members are described.
As shown in fig. 1, the device for preventing the active sludge in the secondary sedimentation tank from running off along with water comprises a secondary sedimentation tank 1, a peripheral transmission mud scraper working bridge 2, a water collecting weir 3, a spraying device 4 and a mud guard 5, wherein the peripheral transmission mud scraper working bridge 2 is arranged on the surface of the secondary sedimentation tank 1, the spraying device 4 is fixed on one side of the peripheral transmission mud scraper working bridge 2 by angle steel, the water collecting weir 3 is connected with the secondary sedimentation tank 1, and the mud guard 5 is fixed on the water collecting weir 3.
As shown in fig. 1, the spraying device 4 further comprises a spraying pipeline and a water pump, holes on the spraying pipeline are 5mm, the distance between the holes is 10cm, the holes and the water surface form an angle of 45 degrees, the spraying pipeline is connected with the water pump, the water pump is placed below the water surface of the secondary sedimentation tank 1, and the clear liquid in the secondary sedimentation tank 1 is directly extracted for pressurized spraying.
As shown in figure 1, the thickness of the mud guard 5 is 1.5mm, the material is 304 stainless steel plate, the mud guard is cut into 500mm, the mud guard is fixed for a circle along the water collecting weir 3, and the height of the mud guard 5 is consistent with that of the water collecting weir 3.
The main function of the secondary sedimentation tank 1 is mud-water separation, activated sludge has certain residence time in the secondary sedimentation tank 1, denitrification reaction can occur to generate gas, the sludge attached with bubbles can become light and float upwards, the sludge floating on the water surface of the secondary sedimentation tank 1 is scattered through the spraying device 4 and releases bubbles, the sludge can be precipitated by self gravity, and the sludge near the water collection weir 3 in the secondary sedimentation tank 1 is intercepted by the sludge baffle 5 to prevent loss along with water. This prevent two device that sink pond activated sludge and run off along with water simple structure, the maintenance of being convenient for can effectually hold back the activated sludge on two sink pond 1 surfaces, prevents to influence two sink 1 play water quality of water and good oxygen pond sludge concentration because of mud runs off along with water.
The device is suitable for the secondary sedimentation tank 1, the peripheral transmission mud scraper working bridge keeps rotating at a constant speed and drives the spraying device 4 to rotate along with the rotation, the spraying water breaks up the sludge floating on the water surface of the secondary sedimentation tank 1 and releases bubbles, the sludge can be precipitated by the self gravity, and the sludge near the secondary sedimentation tank water collection weir 3 is intercepted by the mud baffle plate 5 to prevent the loss along with the water.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without modification to the method and technical solution of the present invention, or the present invention can be directly applied to other occasions without modification, all within the scope of the present invention.
