Description
Technical field
The present invention relates to environmental project technical field of sewage, more particularly, to the one vertical wetland sewage of backflow
Process technique and device.
Background technology
Artificial swamp can divide surface stream and the big class of current wetland two.It is low that surface current artificial wetland builds operating cost, can have
Effect relaxes the impact of waterpower pollutional load, but floor space is big, and designed breeding is inaccurate.Drowned flow artificial wet land divides again level to dive
Stream and vertical subsurface flow, its expenditure of construction relatively surface current artificial wetland is high, but can make full use of Wetland Space play plant, matrix and
Synergy between the key elements such as microorganism, improves the ability removing removal organic polluter, wherein vertical current constructed wetland reoxygenation energy
Power is relatively strong, and nitrification is good, and horizontal drowned flow artificial wet land is due to sewage bottom horizontal flow sheet under matrix, and reoxygenation ability is poor, easily
Being formed based on anaerobe or the environment of amphimicrobe, its denitrification is preferable.
The artificial swamp of single type is often unable to reach water treatment requirement, the most domestic has engendered various combination
Type artificial swamp, to reducing floor space and improving contaminant removal efficiency.The China of Application No. 200303157161.1

System etc..But system disclosed in above-mentioned document is limited only on horizontal structure different types of artificial swamp is combined string
Connection, the problem that actual solution wetland floor space is big, and all it is unable to reach the purpose quickly removing pollutant, its waterpower
The time of staying, often beyond more than 1d, greatly reduces the treatment effeciency of sewage, even too much due to the wetland configuration of series connection, leads
Cause difficult management, labor management is required higher.
Artificial swamp is preferable to the removal effect of ammoniacal nitrogen pollutant, but the most very manages the removal effect of nitrate nitrogen contaminants
Thinking, even in negative removal efficiency, the removal efficiency ultimately resulting in total nitrogen is low.The Chinese patent Shen of Publication No. 101423297
Please disclose a kind of composite vertical current artificial wetland oxygenation system, the method is by arranging emptying bottom vertical current constructed wetland
Pipe carries out intermittent aerating, creates the aerobic and environmental condition of anaerobism alternately change, but this system needs manual adjustment air pressure
The ratio aeration rate of contracting machine and manual start-stop, regular job is relatively complicated and plant running parameter is difficult to regulation.How to ensure
While high denitrification effect, it is achieved the automatic operating of device and the easy problem of management be technical barrier that this area is to be solved and

Combined artificial marsh sewage treatment system etc..But above-mentioned relate to artificial wetland effluent backflow wet land technique be all to follow
Ring pump is placed in and constantly runs the operating mode drawn water, and its electric energy loss is more, and the service life of circulating pump is the longest, how to control reflux pump
Service condition to reduce energy consumption cost, and to reach optimal removal effect be another technical barrier that this area is to be solved.
Additionally, along with the detection in water body environment such as trace toxic pollutant such as agricultural chemicals, medicine and incretion interferent
Frequency and concentrations constantly raise, and cause poisonous effect and enrichment that this pollutant is had by people, and
Highest attention to aquatic ecosystem 26S Proteasome Structure and Function stabilizing influence.Artificial swamp is as a kind of novel ecological sewage treatment
Technology, is used widely in the water of China processes, but compared with external progress, domestic artificial still in research
Wetland removes efficiency and the mechanism stage of Conventional pollution, removes the artificial swamp work of trace toxic pollutant about artificial swamp
Skill not yet has been reported that.

Ground is internal to be blocked.
Sewage flow velocity in the vertical wet field facilities for treating sewage of reverse-flow type can be by regulation vertical current constructed wetland water outlet
The valve of pipe and the valve of horizontal drowned flow artificial wet land outlet pipe are controlled, and coutroi velocity ensures that pollutant is the most fully degraded
Effluent cycle number of times with necessary, finally ensures removal effect.
The removal process of pollutant is mainly included by the vertical wet field facilities for treating sewage of reverse-flow type, and circulating pump draws water at single
During realize the oxygenation to sewage, improve the biodegradability of sewage；Plant absorption in vertical current constructed wetland, absorption dirt
Nutriment in water, and by photosynthetic oxygen evolution, water body is carried out oxygenation, reduce the organic loading of sewage；Top layer gravel matrix is cut
Stay the suspended particulate substance in sewage；Owing to haydite specific surface area is relatively big, beneficially growth of microorganism, when oozing under sewage to haydite layer,
Ammonia nitrogen class material in sewage and organic matter generation Quick Oxidation effect, NH4 +～N is to NO2 -～N and NO3 -～N converts, organic matter
Oxidation forms carbon dioxide；Additionally, due to gravel and the suction-operated of haydite, heavy metal and difficult degradation class material in sewage are equal
Can effectively remove, at horizontal drowned flow artificial wet land, these pollutants will occur further suction-operated；At perpendicular flow artificial
The NO converted in wetland2 -～N and NO3 -～N horizontal drowned flow artificial wet land based on amphimicrobe in the environment of
Denitrification is occurred to change into nitrogen；Sewage iterates through the vertical wet field facilities for treating sewage of reverse-flow type thus finally realizes out
Water water quality up to standard.
Use the inventive method, summed up by the attenuation change monitoring each pollutant and show that every batch sewage disposal time is
About 6h i.e. can reach the optimal removal effect of pollutant, apparatus of the present invention continuously-running, can process 4 batch sewage every day.
