Description
Technical field
The utility model belongs to calcium carbonate production technical field, the sewage disposal being related in calcium carbonate production, and specially one
Sewage disposal system in kind calcium carbonate production.
Background technology
In calcium carbonate production, wastewater source is in sanitary sewage, gas washing waste water and plate compression waste water, and gas washing
The yield of waste water and plate compression waste water is very big, and due to gas washing waste water slant acidity, plate compression waste water meta-alkalescence,
And can not be removed containing a large amount of calcium and magnesium ions, oily substance and larger molecular organics, direct emission not only pollutes environment, and
And water resource serious waste is caused, and the production that reuse also can be because of oily substance and larger molecular organics to calcium carbonate if producing
And qualitative effects, cause production to endanger, it is therefore necessary to treatment for reuse.
Invention content
Sewage disposal system in being produced the technical problem to be solved by the utility model is to provide a kind of calcium carbonate, to life
After production waste water is effectively treated, reuse and discharge standard can be fully achieved.
In order to solve the above technical problems, technical solution used by the utility model is：A kind of dirt in calcium carbonate production
Water treatment system, including sewage collecting pool are sequentially connected processing pond, sedimentation basin, the first filter plant, the by pipeline and pump
The bottom of two filter plants and clear water reserviors, wherein sewage collecting pool, processing pond and sedimentation basin is all connected to sludge concentration tank, described
Processing pond is rectangular, and two bottom sides are equipped with main line aerated conduit, is mutually parallel between the main aerated conduit of both sides, and the two it
Between be connected with more branch line aerated conduits, be mutually parallel between branch line aerated conduit, and vertical with main line aerated conduit；Main line exposes
It is equipped with solarization air cap on feed channel and branch line aerated conduit.
Further, the system also includes medicament addition devices, are connect respectively with processing pond and sedimentation basin.
Further, first filter plant is flame filter press, and the second filter plant is ceramic membrane filter machine.
Further, the sludge concentration tank is also associated with centrifuge, and liquid outlet is connected to dirt by pipeline and pump
Water collecting pit.
Further, sewage collecting pool is connected to processing pond by overflow pipe.
Further, buffer pool is additionally provided between the first filter plant and the second filter plant, buffer pool is equipped with backwash tube
Road is connected to the first filter plant, and clear water reserviors are connected to the second filter plant equipped with backwash pipeline.
The flow setting of the utility model is reasonable, simple in structure, and the waste water in calcium carbonate production process can be effectively treated,
Since the solid content in calcium carbonate waste water is high, by the multistep treatment of sewage collecting pool, processing pond and sedimentation basin, and handling
Medicament is added in pond and sedimentation basin to be handled, most of solid matter in waste water can be quickly and effectively removed, is the later stage
It is primary filtering and secondary filter lighten the load.In addition, aeration pipeline is arranged by processing pond, the water in pond is aerated,
Play the double effects of stirring and aeration, promote waste water and medicament react and the removal of organic matter.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structure top view of processing pond.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and examples：
As Figure 1-Figure 2, the sewage disposal system in a kind of calcium carbonate production, including sewage collecting pool 1, pass through pipe
Road and pump are sequentially connected processing pond 2, sedimentation basin 3, the first filter plant 4, the second filter plant 5 and clear water reserviors 6, and wherein sewage is received
The bottom in collection pond 1, processing pond 2 and sedimentation basin 3 is all connected to sludge concentration tank 7, and the processing pond is rectangular, and two bottom sides are set
There is main line aerated conduit 21, be mutually parallel between the main aerated conduit of both sides, and is connected with more branch line aeration tubes between the two
Road 22 is mutually parallel between branch line aerated conduit, and vertical with main line aerated conduit；Main line aerated conduit and branch line aerated conduit
On be equipped with solarization air cap.
Preferably, the system also includes medicament addition devices 8, are connect respectively with processing pond 2 and sedimentation basin 3.It is used
Medicament be flocculant, such as what PAM flocculant of PAC coagulant.
Preferably, first filter plant 4 is flame filter press, and the second filter plant is ceramic membrane filter machine.From heavy
Form sediment separation, plate-frame filtering to ceramic membrane filter, and filtering rank is by finely, flow setting is reasonable, can subtract as far as possible roughly
The load of light fine filtering apparatus, and filter from simple to complex, the removal effect of impurity is more preferable.
Preferably, the sludge concentration tank 7 is also associated with centrifuge 9, and liquid outlet is connected to dirt by pipeline and pump
Water collecting pit 1.Since the solid content in calcium carbonate sewage is high, the mud of early period is collected by the way that sludge concentration tank is arranged, then into
Row centrifugation, can quickly and effectively reduce sewage solid content.Filter cake after centrifugation can pull away carry out landfill disposal.
Preferably, sewage collecting pool 1 is connected to processing pond by overflow pipe.It, can by the overflow of sewage collecting pool
The bottom for avoiding solid content big enters in processing pond, mitigates processing load.
Preferably, buffer pool 10 is additionally provided between the first filter plant 4 and the second filter plant 5, buffer pool is equipped with backwash
Pipeline is connected to the first filter plant 4, and clear water reserviors 6 are connected to the second filter plant 5 equipped with backwash pipeline.First filter plant
Filtered water can be used for the cleaning of the first filter plant, the water of the second filter plant filtering can be used for the second filter plant or
