Description
Technical field
The present invention relates to oxygenating technology automatically in urban sewage pipe sewage, be specifically related to a kind of manhole that relies on the water body flow automatic oxygenating of sewage conduct downstream, the autonomous waterwheel that pumps up water rotated by built-in dependence flow power in manhole, the sewage in main sewer road in manhole that constantly makes to flow through carries out oxygenation, the riser tubing dissolved oxygen levels, strengthen the degrading activity of the aerobic microbiological in sewage, make in sewage flowing in pipeline constantly by the microbial consumption organic pollution, reach and reduce pollutant index, the effect of purifying waste water.
Background technology
The Water drainage system design mechanism in China city is comparatively complicated at present, especially the old town in city, due to the problem of design year for existence, mostly adopted the even not treated design mechanism that also directly enters urban sewage system of industrial wastewater of confluence of rainwater and sewage, although this mode has the advantage that expense is low on building, the harm of its interflow discharge is more and more obvious; And lower rainwater adopts the discharge mode of confluence of rainwater and sewage by degree of contamination, for the water resource be becoming tight current day, this is also a kind of waste, is not suitable for the long-run development in city; And the old industrial area in some cities may occur due to the supervision not tight, some producers directly enter urban duct by production waste.Variety of problems may appear in above urban sewage pipe, adopts the discharge mode of combined system: the total amount of disposing of sewage that for a moment increases Wastewater Treatment Plant; Second make the sewage pollution characteristic that enters Sewage Plant become more complicated, promote its intractability, increased the operating load of Sewage Plant.
Therefore, the design of current Novel urban drainage pipeline networks, adopt segregation system discharge is that the discharge of industrial wastewater must reach and finally enter Wastewater Treatment Plant with the sanitary sewage interflow again to the sewage network in the city of being allowed for access after the standard of urban sewage pipe discharge and processed through its inner certain processing more; Rainwater adopts separately a set of drainage pipeline networks rainwater can be entered to urban landscape river rainwater is fully used.
The composition of drainage system comprises that sewage network, municipal wastewater pipe network, Wastewater Treatment Plant's three parts of resident residential community form at present.At first the community pipe network imports city planting ductwork by Domestic sewage collecting, relies on transferring of city planting ductwork to enter Wastewater Treatment Plant, enters natural water after harmless treatment.
Pollutant component in municipal wastewater comes from resident's daily life sewage mostly, sanitary sewage refers to the water of using in people's daily life, the water of comprise from lavatory, bathroom, lavatory etc. being discharged, the pollutant component of this class sewage is organic matter mostly, as protein, animals and plants fat, carbohydrate, urea and ammonia nitrogen etc. also contain soap and synthetic detergent etc., sanitary sewage all needs to process and just can discharge and enter natural water through Sewage Plant.
Current municipal wastewater arrives Wastewater Treatment Plant from resident family and adopts pipeline to carry, the construction of Sewage Plant is general all near river, be beneficial to the normal operation that its timely discharge of processing water guarantees Wastewater Treatment Plant, therefore municipal wastewater need be through long distance, the long conveying from arrival Wastewater Treatment Plant of resident family, in this flow process, in municipal wastewater, there is sufficient nutriment to digest and assimilate for microorganism, be beneficial to the propagation of self.
Sewage conduct for the city old city, due to long neglected and in disrepair, sewage the depositional phenomenon of larger particles will certainly occur in duct bottom through conveying year in year out, and along with the increase of bed mud deposition, dissolubility oxygen in bed mud can reduce gradually, for a long time, to occurring the environment of anoxic in can causing the bed mud in duct bottom under dissolved oxygen depletion, anoxia condition only can be beneficial to the growth and breeding of anaerobe, and suppresses the vital movement of aerobic quasi-microorganism.
Anaerobe carries out anaerobic digestion to organic matter in anaerobic environment, can produce stench and the incendive gases such as hydrogen sulfide, methane.This class gas can not get certain dilution because ducted oxygen is not enough, if accumulate for a long time the accident that may meet accident.For example on June 23rd, 2012, in the one place's sewage conduct maintenance desilting process of Jinan City, Shandong Province, the constructor falls in a swoon suddenly because anoxic is poisoning when lower well operations, and aboveground personnel also in succession fall in a swoon because of anoxic in the process of suing and labouring of going into the well.On August 12nd, 2010 is in Yangzhou development zone, Jiangsu Province, and the constructor causes 3 people all rescue measures proved ineffectual when maintenance of underground breaks sewage conduct because anoxic is poisoning dead.Above two routine accidents are all because accumulating a large amount of methane class toxic and harmfuls in sewage conduct, cause oxygen content deficiency in the sewage conduct of down-hole, cause the anoxic poisoning symptom in the unwitting situation of operating personnel.Reach finite concentration and work as methane concentration, in the situation that meet naked light, danger that even can be explosion caused, cause serious people's property loss.
The conveying of sewage all needs the Flows through long distance, and in the course of conveying of long distance, current pipeline only works to transfer sewage, the inner space of pipeline is not taken full advantage of.Pipeline is only to transfer but be a good reaction vessel for each quasi-microorganism in sewage for sewage, such as in pipeline, not only having anaerobic environment but also abundant nutriment is arranged as source of nutrition, therefore the decomposition active of anaerobe just can very active meeting discharge poisonous class gas with this understanding; And the aerobic microbiological be present in equally in sewage is originated owing to lacking sufficient dissolved oxygen, cause the vital movement of aerobic microbiological to be suppressed, can't carry out conventional innoxious decomposition to the organic matter in water.
Therefore for promoting self capacity of decomposition of aerobic microbiological, must take that increasing oxygen content in sewage is prerequisite.Only have dissolved oxygen concentration to reach the requirement of microorganism normal activities, just can give full play to the ability of its decomposing organic matter, to promote it to organic decomposition in sewage, and in pipeline, microorganism will directly promote the organic matter of Sewage Plant to process the decline of load to organic decomposition, improve the disposal ability of Sewage Plant, reduce the cost of production of Sewage Plant.
Dissolved oxygen for how in lifting sewage, the oxygen content in sewage conduct roughly has following source at present:
1, in the junction in main sewer road; often have in the branch sewer access main pipeline of side; the exit position of branch sewer generally all can be higher than main pipeline, and when sewage flows into main pipeline from arm, current can form the air that the fierce ponding drop at this moment of impacting manhole of drop can be brought a large amount of external worlds into like this.
2, carry the non-flowing full of the many employings of pipeline of sewage to carry, thereby can more than the pipeline middle water level, leave this part space of segment space and can accumulate the air that the external world enters, the dissolubility self had at the flow process Air of water body makes the sewage oxygen content be increased in can slowly being dissolved in sewage.
3, current can produce the whirlpool phenomenon when by upstream, entering downstream at the manhole place, and these whirlpools can produce interlaced flow phenomenon in various degree, stir air-flow and enter water body, oxygenous dissolving.
4, in city, pipeline junction everywhere often has drop well is set in order to make upstream line access downstream line smoothly, and the drop failed to be convened for lack of a quorum due to height at drop well place upper water produces the phenomenon that drops rapidly, and water velocity moment strengthens.In its accelerator, current contact with air and directly make current carry large quantity of air secretly to enter downstream line.
But all there is certain defect in four kinds of above-mentioned oxygenation modes:
1) the formed air of impact force that the oxygenation mode of the 1st class relatively is confined to the arm current is brought in, and when current, the weak air dissolves that can drive of hour its impact force is more limited.
2) the 2nd class oxygenation mode is to rely on the ducted air of non-flowing full to dissolve gradually to increase oxygen content, even but for current municipal pipeline the non-flowing full of pipeline but its inner oxygen content is seldom little to the sewage oxidation effect, after in the maintenance of current municipal pipeline, the normal personnel that occur enter in manhole, the gassing phenomenon occurs, its reason is exactly to lodge in ducted factor because inner oxygen content is very few and generate the toxic gas such as hydrogen sulfide due to the decomposition active of the anaerobe in sewage.
3) the oxygenation mode of the 3rd class and the 4th class is to rely on the draught effect of manhole by drop or whirlpool, air to be brought into and made sewage obtain oxygenation, but it is not too many that this mode can produce the manhole proportion of drop or whirlpool phenomenon in the overall pipe network in city, so its oxidation effect neither be obvious especially.
The restriction of the existing defect of above a few class oxygenation measure and suffered pipeline therefore, is badly in need of convenient, the reliable and efficient oxygenating technical measures of a class to promote supplementing of its dissolved oxygen in actual environment.
Summary of the invention
For current municipal wastewater pipeline is inner in course of conveying, containing hypoxgia, cause aerobic microbiological to can not get good growth in pipeline, and pipeline has only played the effect of transportation sewage, wasted the problem that section carries out the effect of sewerage treatment within it, the object of the invention is to, a kind of manhole that relies on the water body flow automatic oxygenating of sewage conduct downstream is provided, the waterpower agitating device is installed in this manhole, being used for stirring current supplements and enters in downstream line rapidly to drive outside air, thereby the vigor of the aerobic microbiological in the raising downstream line, make it decompose absorption to organic pollution in sewage, obtain the effect that reduces water pollutant content, and the processing load reduction that makes Wastewater Treatment Plant is to help the processing cost that reduces Wastewater Treatment Plant.
In order to realize above-mentioned task, the present invention takes following technical solution:
A kind of manhole that relies on the water body flow automatic oxygenating of sewage conduct downstream, comprise manhole, a side at the manhole inwall has the upstream branch sewer, the bottom of manhole is the main sewer road, flow into the main sewer road under the current direction of upstream branch sewer, it is characterized in that, in the manhole bottom, the waterwheel that pumps up water is installed, this waterwheel that pumps up water is positioned on the water surface in main sewer road, and by fixed support, is fixed on the borehole wall of manhole both sides.
The manhole of the dependence water body flow of the present invention automatic oxygenating of sewage conduct downstream, simple in structure, easy for installation, be convenient to carry out detachable maintaining.The waterwheel that pumps up water used possesses certain buoyancy can suitably be adjusted at the depth of immersion in manhole with the height of pipeline middle water level, prevent that water level is too low and the waterwheel that causes pumping up water stops operating, and the rotational energy of the waterwheel that pumps up water source does not provide power to save a set of complete energy supply device, convenient construction for ducted water velocity does not need outside.Its advantage is:
1, rely on the rotary action of the waterwheel that pumps up water to play the oxidation effect good to sewage, the growth and breeding that makes the sewage oxygen content obviously increase to aerobic quasi-microorganism has played positive role.
2, owing to having promoted the oxygen content advanced in factory's sewage after the sewage oxygenation, can the aeration rate of favourable minimizing in the aeration in sewage treatment process of Sewage Plant, to reducing the Sewage Plant energy consumption, be very helpful.
3, in pipeline the increase of oxygen content to the pernicious gas that accumulates in pipeline such as: the gases such as methane, hydrogen sulfide, carbon monoxide have certain diluting effect, in order to avoid these pernicious gas over-burdens produce when negative effect is as usual some pipe-line maintenance workmans to pipeline maintenance due to the too high intoxicating phenomenon that occurs of ducted harmful gas concentration.
