Detailed description of the invention
As shown in Figure 1 and Figure 2, the present embodiment is regulated and stored system with bionical breast-stroke air bag for a kind of city river discharge outlet, pretreatment system, bionical breast-stroke air bag system two parts of regulating and storing are constituted, and all build on riverbank 12；Pretreatment system can dam major part combined sewer overflow water or early-stage rainwater, and intercepting sewage carries out preliminary treatment, removes large particulate matter and gravel, protects follow-up bionical breast-stroke air bag to regulate and store system；Bionical breast-stroke air bag regulate and store system work time, air bag is in river water body 11, is not take up the space on riverbank 12.
Pretreatment system is made up of Vatch basin 1, coarse rack 2, fine fack 3, setting pot 4 successively.
Vatch basin 1 is arranged at discharge outlet, dams the water body that discharge outlet precontamination is serious, enters air bag and regulates and stores system, and during big rainfall, the draining overflow in later stage enters river course.
The grid gap 20～40mm of coarse rack 2, dams to large particulate matter in the sewage dammed.
The grid gap 5～10mm of fine fack 3, dams to the sewage small particles material dammed.
The design time of staying of setting pot 4 is design discharge 20s in rainy season, for precipitating the sand grains removed in sewage.Being provided with big pipe a and two outlet conduits of tubule b in setting pot, tubule b is directly accessed city planting ductwork or treatment in situ system, at discharge outlet flow hour, the water outlet after sand setting directly receives pipe or process, and does not enter bionical breast-stroke air bag and regulates and stores system；Big pipe a accesses bionical breast-stroke air bag and regulates and stores system, pipe arranges valve c, induction apparatus 5 controls, and when wet-weather flow is big, and setting pot inflow is beyond b pipeability, valve c opens, and the bionical breast-stroke air bag system of regulating and storing of unnecessary water yield importing is stored.
Bionical breast-stroke air bag system of regulating and storing is made up of induction apparatus 5, air compressor machine 6, gasbag chamber 7, air bag 8, air bleeding valve 9, submersible sewage pump 10 successively.
Induction apparatus 5 is arranged in setting pot, by Liquid level, has two kinds of operating modes:
1) water yield hour, owing to the big pipe a in setting pot 4 is controlled to be closed by valve c, setting pot 4 flow of inlet water is little, and water inlet all imports treatment in situ system by tubule b, and setting pot 4 water level keeps low water level, and induction apparatus 5 does not has signal；
2) when rainy season, the water yield was big, setting pot 4 flow of inlet water exceeds tubule b conveyance capacity, and setting pot 4 water level rises, during to certain water level, induction apparatus 4 receives default water level signal, valve c on big pipe a in setting pot 4 is opened, meanwhile, starts air compressor machine 6, start to inflate for air bag 8, discharge outlet sewage enters air bag 8 and stores, and after rainfall terminates, the sewage pump stored in air bag 8 is entered submersible sewage pump 10 city planting ductwork or treatment in situ system processes.Meanwhile, on the big pipe a in setting pot 4, valve c closes, and the air bleeding valve on air bag 8 is opened, and in air bag 8, sewage gradually decreases, in air bag 8 gradually retraction gasbag chamber 7.
Air compressor machine 6 rises at the water level of setting pot 4, induction apparatus 5 starts when sending signal, inflate for air bag 8, setting pot 4 water level decreasing, after certain water level, induction apparatus 5 is closed when sending signal, run duration, and air compressor machine 6 is according to air bag 8 inflation situation and air bag 8 and the situation intermittent duty of river water body hydraulic pressure difference.
Gasbag chamber 7, for storing and protect the cavity of air bag 8, can be made by brick, steel, concrete etc..
Originally system of regulating and storing uses bionic principle, the male frog in bionical Rana nigromaculata, and it is respectively arranged with a pair air bag on bicker both sides, is in contraction state at ordinary times, and when Rana nigromaculata sounding, air bag bloats, and is equivalent to resonance chamber, and the sound making Rana nigromaculata vocal cords be sent expands because of sympathetic response.Originally regulate and store system constructing intraocular balloon, made by the organic material with anti-stab performance, not inflating, do not store sewage, air bag 8 is in contraction state, it is stored in gasbag chamber 7, when wet-weather flow is big, when induction apparatus 5 sends signal, air compressor machine 6 starts inflation, air bag 8 bloats from gasbag chamber 7, stores sewage.The advantage of system of originally regulating and storing be air bag 8 flat time be in contraction state, for soft structures, it is to avoid tradition is regulated and stored system hard structure, and floor space is big, and construction cost is high, the shortcomings such as difficulty of construction is big.
Air bleeding valve 9 is arranged on air bag, during air bag 8 stores sewage, suitably opens aerofluxus according to air pressure, keeps air bag 8 water inlet smooth-going, and discharges excessive gas when air bag shrinks.
Submersible sewage pump 10 is connected by being arranged on the drain pipe bottom air bag 8, and sewage lifting to the sewage network stored in by air bag 8 enters Sewage Plant and focuses on or enter scattered treatment in situ system.Due to regulating and storing of air bag 8, the sewage in air bag slowly can be extracted out after rainfall terminates by the submersible sewage pump 10 that system is configured with miniaturization.
The present embodiment in practice, first should according to basic data, differentiate different time sections (dry season, rainy season, in the daytime, night) discharge outlet flow, and hydraulic condition of river condition, including flow velocity, water level, the depth of water etc..Carry out discharge outlet measurement again, Combining with terrain figure data, pretreatment system and air bag is selected to regulate and store the position of system and scale, especially it should be noted that the size of setting pot 4 outlet pipe (big pipe a and tubule b), tubule b depend on air bag emptying time, sewage disposal in dry season scale, treatment in situ facility size；Big pipe a depends on Vatch basin flow of inlet water, and air bag is regulated and stored system scale；The unlatching of big pipe a is achieved by the valve c on the induction apparatus 5 in setting pot 4, big pipe a.Air bag system scale of regulating and storing depends on designing raindrop type, return period size, discharge outlet pollutant levels, urban river water environmental carrying capacity, subsequent treatment facility scale etc.; scale should be appropriate; too small river training water quality is had little significance; excessive increase construction investment, also easily to urban river water environment overprotection.For avoiding taking river flood control section and flood erosion, gas-bag system is arranged in city river and the river course concave bank that gate dam controls as far as possible.
