Water conveyance conduit improves structure chart.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
In conjunction with specific embodiments, the utility model is further described in face.
The embodiments of the present invention provides a kind of novel adjusting pH device (following letter for leachate equalization basin
Claim " device "), referring to Fig. 1 comprising: leachate collection pool 1, leachate collection pool pass through percolate raw water pipeline 2
It is connected to leachate equalization basin 3, leachate collection pool passes through percolate raw water pipeline for the percolate of leachate collection pool
It is transported to leachate equalization basin.
And be to reach the purpose for reconciling leachate collection pool output percolate pH value, referring to Fig. 1, whole device further includes sulphur
Sour dosing container 4, sulfuric acid dosing container include but are not limited to sulfuric acid dosing tank or sulfuric acid medicine-adding bin, sulfuric acid dosing container 4
It is connected to percolate raw water pipeline 2 by adjusting pipeline 5, pipeline 5 is adjusted and is provided with sulfuric acid dosing pump 6 and check-valves 7,
Check-valves is set to the output end of sulfuric acid dosing pump, and sulfuric acid dosing pump 6 is metering pump.The sulphur accommodated in sulfuric acid dosing container 4
Acid solution be conveyed to percolate raw water pipeline in case of need and to flow through the percolate of percolate conveyance conduit into
Row pH is adjusted.
In Fig. 1, it is set to the adjusting pipeline access port and percolate raw water pipeline of percolate raw water pipeline 2
Mixer 9 between delivery outlet can effectively promote the mixing efficiency of percolate and sulfuric acid solution, be more fully mixed.Mixing
The output end of device is provided with pH detector 10, which can be with percolate in real-time detection percolate raw water pipeline
PH value then carries out foreign intervention by the way that sulfuric acid solution is added, so that the pH value of percolate is adjusted to pre- when being more than preset value
If range.
The device is to realize that intelligentized control method may be incorporated into control element 8, is connected to sulfuric acid dosing pump 6, pH detection
Instrument 10, control element 8 can choose PLC controller, and PLC controller receives the detection signal from pH detector 10, and according to
