Abstract
The utility model provides a water conservancy cavitation mud decrement device, belongs to sewage treatment technical field. The device's second bottom of gullet connects gradually efflux intake pump, ejector and first basin, and outlet water pump is connected to the bottom of first basin. Two heavy ponds are arranged mud and are come water to enter into the ejector after the pressurization of efflux intake pump, because the choked flow effect of orifice plate, the increase of water rate of flow of fluid, the pressure decrease, when differential pressure to vapour pressure or even negative pressure, the gas that dissolves in the fluid can release, the fluid is vaporized and is produced a large amount of cavitations bubble simultaneously, the liquid ambient pressure resumes to spray the expansion rapidly afterwards, the cavitation bubble is vanished in the twinkling of an eye, thereby produce cavitation, aquatic mud cell disruption cell wall, release composition and cytoplasm that the intracellular contains, so that further degradation, the output of mud has been reduced. The mud decrement 50 60%, sewage after the mud decrement enters into first basin, handles in sending sewage biochemical treatment device to with the sewage pump, can effectively improve the biodegradability of sewage simultaneously.
Description
Technical field
The utility model relates to a kind of hydrodynamic cavitation mud decrement device, belongs to technical field of sewage.
Background technology
In the biological treatment process of activated sludge process sewage, produce substantial amounts of biological sludge, need separated, stable, digest, be dehydrated and the step such as disposal.This needs substantial amounts of capital expenditure and high operating cost.
Hydrodynamic cavitation is that fluid is when flowing through a fluidic device, choked flow effect due to orifice plate, flow rate of liquid increases, pressure reduces, when pressure is down to vapour pressure even negative pressure, dissolve gas in a fluid can discharge, simultaneously fluid vaporization and produce a large amount of cavitation bubble, liquid perimeter pressure recovers rapidly injection expansion subsequently, cavitation bubble moment vanishes, thus produces cavitation.
Hydrodynamic cavitation produces cavitation by continuous print compression and dilating effect, and this acts on the formation with microbubble, grows and rupture and embody in the solution, with this fracturing cell walls, discharges intracellular contained composition and cytoplasm, in order to degrade further.When sludge recirculation system, the degradability of cell can be strengthened, decrease the yield of mud, it is achieved the mud decrement of sewage treatment plant.
Summary of the invention
In order to overcome problems of the prior art, the utility model provides a kind of hydrodynamic cavitation mud decrement device, this mud decrement device Hydrodynamic cavitation compresses and expands generation cavitation by continuous print, this acts on the formation with microbubble, grows and rupture and embody in the solution, with this fracturing cell walls, discharge intracellular contained composition and cytoplasm, in order to degrade further.When sludge recirculation system, the degradability of cell can be strengthened, decrease the yield of mud, it is achieved the mud decrement of sewage treatment plant.
The technical solution adopted in the utility model is: a kind of hydrodynamic cavitation mud decrement device, it includes the first tank and the second tank, it also includes an ejector, described second tank is provided with sludge from final clarifier and carrys out water pipe, the bottom of the second tank is sequentially connected with jet intake pump, ejector and the first tank by pipeline, the bottom of described first tank connects water pump by pipeline, goes out water pump and connects biochemical treatment tank by pipeline.
The beneficial effects of the utility model are: this hydrodynamic cavitation mud decrement device includes the first tank, the second tank and ejector, the bottom of the second tank is sequentially connected with jet intake pump, ejector and the first tank by pipeline, the bottom of the first tank connects water pump by pipeline, goes out water pump and connects biochemical treatment tank by pipeline.From activated sludge process biochemistry pool water outlet after second pond separates, muddy water is settled from flowing in the second tank bottom it, enter in ejector after jet intake pump pressurizes, choked flow effect due to orifice plate, aqueous fluid flow velocity increases, pressure reduces, when pressure is down to vapour pressure even negative pressure, dissolve gas in a fluid can discharge, simultaneously fluid vaporization and produce a large amount of cavitation bubble, liquid perimeter pressure recovers rapidly injection expansion subsequently, cavitation bubble moment vanishes, mud clasmatosis cell membrane in water, discharge intracellular contained composition and cytoplasm, to degrade further, decrease the yield of mud, realize the mud decrement of sewage treatment plant.Mud decrement 50-60%, the sewage after mud decrement, enter in the first tank, deliver to biochemical sewage treatment device processes with sewage pump, the biodegradability of sewage can be effectively improved simultaneously.
Accompanying drawing explanation
Fig. 1 is the work system figure of a kind of hydrodynamic cavitation mud decrement device.
In figure: 1, the first tank, the 2, second tank, 3, jet intake pump, 4, ejector, 5, go out water pump.
Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the utility model is illustrated:
Fig. 1 shows the work system figure of a kind of hydrodynamic cavitation mud decrement device.In figure, this hydrodynamic cavitation mud decrement device includes the first tank the 1, second tank 2 and ejector 5, second tank 2 is provided with sludge from final clarifier and carrys out water pipe, the bottom of the second tank 2 is sequentially connected with jet intake pump 3, ejector 4 and the first tank 1 by pipeline, the bottom of the first tank 1 connects water pump 5 by pipeline, goes out water pump 5 and connects biochemical treatment tank by pipeline.
Use above-mentioned technical scheme, when fluid flows through this device, Hydrodynamic cavitation produces cavitation by continuous print compression and dilating effect, this acts on the formation with microbubble, grows and rupture and embody in the solution, with this fracturing cell walls, discharge intracellular contained composition and cytoplasm, in order to degrade further.When sludge recirculation system, the degradability of cell can be strengthened, decrease the yield of mud, it is achieved the mud decrement of sewage treatment plant.
From activated sludge process biochemistry pool water outlet after second pond separates, muddy water is settled from flowing in the second tank 2 bottom it, enter in ejector 4 after jet intake pump 3 pressurizes, during entering fluidic device, choked flow effect due to orifice plate, aqueous fluid flow velocity increases, pressure reduces, when pressure is down to vapour pressure even negative pressure, dissolve gas in a fluid can discharge, simultaneously fluid vaporization and produce a large amount of cavitation bubble, liquid perimeter pressure recovers rapidly injection expansion subsequently, cavitation bubble moment vanishes, thus produce cavitation, mud clasmatosis cell membrane in water, discharge intracellular contained composition and cytoplasm, to degrade further, decrease the yield of mud, realize the mud decrement of sewage treatment plant.Mud decrement 50-60%, the sewage after mud decrement, enter in the first tank 1, deliver to biochemical sewage treatment device processes with sewage pump 5, the biodegradability of sewage can be effectively improved simultaneously.
