Description
Technical field
The invention belongs to technical field of sewage, a kind of sewage in expressway service integrated treatment dress is more particularly to
Put, it is adaptable to the improvement and maintenance of Expressway Service ecological environment.
Background technology
With the fast development in transport development field, China has built numerous highways, correspondingly also builds
Substantial amounts of service area.These service areas are mostly away from the municipal pipeline in city, it is impossible to using the sewage disposal system of city planting ductwork.
Currently, the unprocessed direct discharge mostly of service area sewage, not only causes surrounding enviroment water pollution and soil pollution, also creates
Water resource serious waste.
In recent years, with the raising that governments at all levels are realized to highway environment protection, existing a small amount of area starts the service area to along
Carry out sewage disposal.Current Expressway Service uses traditional wastewater treatment technology substantially, general to use bioanalysis technique, should
The defect of technique is that Installed capital cost is high, water requirement is big, anti-shock loading is poor, maintenance management is complicated.Due to highway
The features such as service area sewage has that the fluctuation of small water, water quality and water is big, concentration of nitrogen and phosphorus is high in sewage, it is difficult to find suitable place
Reason equipment.
Sewage in expressway service source includes that flush the toilet draining, food and drink draining, carwash draining, road of communal bathroom is clear
Wash the parts such as draining, wherein water is big, pollutant concentration is high mainly flush the toilet draining and food and drink draining.Due to service area sewage
Nitrogen and phosphorus content is high, typically about the 3 of sanitary sewage times (ammonia nitrogen peak value is up to 150mg/L), routine biochemistry treatment water outlet total nitrogen
It is down to below 50mg/L and all there is larger difficulty.Additionally, service area sewage TP contents are also very high, synchronous high-efficiency dephosphorization is realized,
Difficulty is also very big.For urban wastewater treatment firm pollutant emission standard, service area sewage disposal it is important that realizing efficiently de-
Nitrogen dephosphorization, wherein denitrogenation are crucial.
The difficult point of sewage in expressway service denitrogenation is COD removals uncoordinated with total nitrogen removal.Due to service area
Sewage is mainly food and drink and toilet-flushing sewage, and biodegradability is good.Organic matter degradation is obtained quickly in conventional water treatment process, COD compared with
Easy qualified discharge.But after organic matter degradation, the nitrifying process of ammonia nitrogen needs the longer residence time.And ammonium oxidation is produced
Raw nitrate needs the organic carbon source could to complete denitrification denitrogenation.In Practical Project, due to the fast degradation of COD, cause
Denitrification denitrogenation process carbon source is not enough, and nitrogen removal rate is very low.Existing handling process water outlet ammonia nitrogen, total nitrogen can not be simultaneously up to standard
It is critical only that the unbalanced supply of the carbon source in nitrification, denitrifying carbon source demand and processing procedure, carbon source it is too early treated
It is consumed in journey.It is additionally to add carbon source during sewage denitrification generally to solve the unbalance method of carbon source.But it is extra to throw
Plus carbon source needs medicament expense higher to use, and dramatically increases processing cost.
Therefore, the small sewage treatment equipment of small investment is badly in need of in Expressway Service.On the one hand, it is desirable to this kind of small-sized dirt
Water treatment facilities investment is little, is easy to safeguard, disposal ability is strong, and effect is good, and discharge standard is met after sewage disposal；The opposing party
Face, it is desirable to service area sewage can be back to after being processed through regeneration flush the toilet, afforest, road is rinsed etc., reduces clear water resource consumption,
Reach water saving, emission reduction, ecology, the effect of environmental protection.

Nitration reaction, wetland effluent proceeds denitrification into horizontal baffling wetland immediately, and then realizes ammonia nitrogen, total nitrogen synchronous high-efficiency
Removal.
2) horizontal baffling wetland effluent flows into Synthetic Biological Pond through open channel.The various submerged plants of companion planting in Synthetic Biological Pond,
On the one hand, because hypoxgia is dissolved in current wetland water outlet, directly discharge can cause receiving water body fishes and shrimps dead, through Synthetic Biological Pond
Can qualified discharge after reoxygenation；On the other hand, Synthetic Biological Pond implants can also further absorb Dissolve N and P, adsorption particle
Thing, improves water transparency.Synthetic Biological Pond effluent reuse is flushed the toilet in service area, carwash, greening irrigation etc., reduces service area clear
Water resources consumption, water saving, emission reduction.
It should be appreciated that for those of ordinary skills, can according to the above description be improved or converted,
And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
