Description
Technical field
The present invention relates to the municipal engineering fields, the routine inspection well of replacing specifically in existing sewage conduct is the oxygenation manhole, and by the sewage conduct oxygenation of this automatic oxygenation manhole to this manhole downstream, improve the pipeline dissolved oxygen, strengthen microbial activity in sewage, purify waste water in the sewage transport process.
Background technology
The drainage system system in China city is comparatively complicated at present, the old town in city is because the age problem has adopted the even not treated system that also directly enters the urban sewage system of industrial wastewater of confluence of rainwater and sewage mostly, and the harm of its interflow discharging is more and more obvious although this method has superiority economically.Industrial wastewater without certain processing directly enter municipal sewage pipe network due to its contain complicated pollutant component to urban pipe network even the normal operation of Sewage Plant all can bring serious harm.
And the direct discharging of rainwater flows into foul sewer system and also has certain defective, because the degree of contamination of rainwater is far away from sanitary sewage and industrial wastewater and the shortage of water resource at present is more and more serious.Therefore so this discharging modes have highlighted the waste to water resource, to adopt the segregation system discharging be industrial wastewater more enters sewage network and collaborate finally to enter Wastewater Treatment Plant with sanitary sewage and obtain harmless treatment through certain processing in the design of present Novel urban drainage pipeline networks; Rainwater adopts separately a cover drainage pipeline networks rainwater can be entered 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 residential quarter pipe network is collected the remittance city planting ductwork and is relied on transferring of city planting ductwork to enter Wastewater Treatment Plant, enters natural water after harmless treatment.
Pollutant component in sewage comes from resident's daily life mostly, sanitary sewage refers to the water used in people's daily life, the water of comprise from the lavatory, bathroom, lavatory, dining room and laundry etc. being discharged, the pollutant component of this class sewage contains more organic matter, also contain soap and synthetic detergent etc. as protein, animals and plants fat, carbohydrate, urea and ammonia nitrogen etc., and the pathogenic microorganism that occurs in the ight soil of being everlasting, be disease carrying germ etc. as parasitic ovum and intestines.Because therefore the complicated component of this class sewage needs just can enter water body after treatment.
Present sewage arrives Wastewater Treatment Plant from resident family and adopts pipeline to carry, because the construction of Sewage Plant generally all will be beneficial to the normal operation that its timely discharging of processing water guarantees treatment plant near the river, institute need be through the conveying of very long distance in order to caused sewage to arrive Wastewater Treatment Plant from resident family.
For the sewage conduct in city old city due to long neglected and in disrepair, sewage will certainly be in duct bottom generation depositional phenomenon through conveying year in year out, and along with the ducted circulation of air of the increase meeting of deposition becomes very difficult so can cause the environment that can occur anoxic in the deposit of duct bottom, this is an excellent breeding chance for the anaerobe in sewage.
Anaerobe carries out anaerobic digestion to organic matter in anaerobic environment can produce stench and the incendive gases such as hydrogen sulfide, methane.If can not get certain dilution because ducted oxygen is not enough, this class gas accumulates for a long time the accident that may meet accident.For example on May 26th, 2011, blasted at a sewage conduct in North Star village, the north suburb, Xi'an the morning, and near directly causing, resident's glass housing is broken.And be a place Wastewater Treatment Plant outside demolition point hundreds of rice, this just explosion hazard gases accumulate for a long time so that concentration has reached upper explosion limit and produced ill effect.The harmfulness of the explosion hazard gases that accumulates in sewage conduct although this incident does not cause casualties has been beaten alarm bell to the municipal administration personnel.
Even the foul gas that accumulates in pipeline is without explosion danger, but the lower well operations impact for the pipeline maintenance personnel is very large, in case in manhole, oxygen concentration is too low, and intoxicating phenomenon probably occurs after crossing going into the well of staff at most in the hydrogen sulfide gas that the bottom anaerobism produces, serious harm maintainer's normal operation, this type of event also is common in all kinds of news report.
The conveying of sewage all needs the Flows through long distance, and pipe present in so remote course of conveying does not take full advantage of pipeline space to only having played the effect of transferring sewage.Pipeline is only the effect of transferring for sewage but is a good reaction vessel for each quasi-microorganism in sewage, such as producing all kinds of pernicious gases because the anaerobe in the serious therefore bed mud of anaerobic condition reacts through the oneself in pipeline, aerobic microbiological can be because the restriction of living environment can't be carried out self-reproduction.If the aerobic capacity of decomposition of the aerobic microbiological in sewage can be applied to the decomposition to sewage in pipeline, this will give full play to pipeline as the effect of the reaction vessel of microorganism, make its each quasi-microorganism carry out therein normal vital movement, organic load in organic decomposition and then reduction sewage in promotion sewage, and then also can directly suppress the activity of anaerobe, be beneficial to the environment that improves pipe interior.
If but to improve self capacity of decomposition of aerobic microbiological, must be to increase in sewage oxygen content as prerequisite.The requirement of only having oxygen concentration to reach the microorganism normal activities just can be given full play to its capacity of decomposition and promote organic decomposition in sewage, and in pipeline, microorganism will directly promote the decline of the processing load of Sewage Plant to organic decomposition, improve the disposal ability of Sewage Plant, reduce the cost of production of Sewage Plant.
The prerequisite that improves microbial activity is to increase oxygen content in sewage, and present ducted sewage content roughly has following source:
1. carry at present the non-flowing full of the many employings of pipeline of sewage to carry, thereby can leave free space this part space and can accumulate the part air more than the pipeline middle water level, rely on the dissolubility of self to make the sewage oxygen content be increased in can slowly being dissolved in sewage at the flow process Air of current.
2. everywhere pipeline junction often has and drop is set in order to make upstream line access downstream line smoothly advances in the city, advances to locate in drop the drop that upper water fails to be convened for lack of a quorum due to height and produces the phenomenon that drops rapidly, and water velocity moment strengthens.Current contact with air and directly produce current and carry large quantity of air secretly and enter downstream line in its accelerator, have increased oxygen content in sewage.
3. current can produce the whirlpool phenomenon at the manhole place when entering the downstream by the upstream, and these whirlpools can produce interlaced flow phenomenon in various degree.The dissolving of more oxygen just can occur in whirlpool place at this moment, directly increases the vital movement that oxygen content in sewage is beneficial to aerobic microbiological.
But all there is certain defect problem in three kinds of above-mentioned oxygenation modes:
1. first kind oxygenation mode is to rely on the ducted air of non-flowing full to dissolve gradually to increase oxygen content, even but for present 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 present 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.
2. the oxygenation mode of Equations of The Second Kind and the 3rd class is to rely on the draught effect of manhole by drop or whirlpool, air to be brought into to make sewage obtain oxygenation, but this mode can produce the manhole proportion of drop or whirlpool phenomenon in the overall pipe network in city be not too many, so its oxidation effect neither be obvious especially.So be badly in need of a kind of technical scheme of promoting and better implementing of being easy under such real background.
