Description
Technical field
The utility model belongs to technical field of sewage, and in particular to a kind of tunnel sewage purification processing system.
Background technology
With the rapid development of railway construction in China, in Railway Construction Projects, it is increasing that tunnel occupies ratio.And tunnel
The construction of road engineering inevitably changes original ambient condition, and environment may be made to be sent out to the direction for being unfavorable for the mankind
Exhibition, so as to cause environmental pollution.
At present, the sewage water treatment method of generally use is by mechanical pump drainage or to draw sewage in hole in China's constructing tunnel
Tunnel portal sedimentation basin is flow to, sewage is stopped certain time in hole sedimentation basin, is discharged after suspension precipitation.Due to by tunnel
Road hole place limits, and utilizable area is fairly limited, sets large-scale sedimentation basin extremely difficult, causes the settlement of sewage time
Deficiency, in sewage about 30%~50% suspension can only be removed, therefore constructing tunnel sewage is typically discharge beyond standards.
Up to the present, it is still the vast Railway Environment protection work of puzzlement that the processing of China railways constructing tunnel sewage is up to standard
The a great problem of author, this does not only have the reason for fund aspect, and immature also turn into of technical elements hinders tunnel sewage
One big bottleneck of processing.
The content of the invention
System imperfection during current tunnel the dirty water decontamination handles, effect be poor, sewage row in order to solve for the utility model
Put the problems such as not up to standard, there is provided a kind of tunnel sewage purification processing system.
The utility model adopts the following technical scheme that：
A kind of tunnel sewage purification processing system, including some fixed pump stations, sedimentation basin, automatic feeding device and gravity type
Valveless filtering pool, the sedimentation basin include first order sedimentation basin, the second level sedimentation basin and the 3rd set gradually according to water (flow) direction
Level sedimentation basin, the automatic feeding device include the molten medicine-chest with control system, and molten medicine-chest side wall is provided with discharge nozzle, discharge nozzle
Measuring pump and valve are provided with, fixed pump station is connected with the water inlet of first order sedimentation basin, and the water inlet of first order sedimentation basin is set
There is automatic feeding device, the delivery port of second level sedimentation basin is provided with automatic feeding device, and gravity valveless filter sinks with the third level
Shallow lake pond connects.
Barricade is provided among the first order sedimentation basin and second level sedimentation basin.
Barricade is provided among the second level sedimentation basin and third level sedimentation basin.
Slope is provided with the first order sedimentation basin.
The molten medicine-chest is provided with stirring rod.
The beneficial effects of the utility model are as follows：
A kind of novel system of the utility model as Tunnel Engineering the dirty water decontamination handles, precipitation from wastewater suspended substance,
PH value, environmental protection etc. are neutralized, compared with traditional sewage water treatment method, the system has compact-sized, simple to operate and high
The characteristics of imitating low consumption, it is often more important that reached environmental requirement, protected environment.Therefore the perfect traditional sense of system supplement
On tunnel sewage disposal system, make China constructing tunnel horizontal and improve a step, there is extensive promotional value.
