Specifically, being connected between the duct type static mixer 4 and water-distributing device 510 by water pipe.

Specifically, being connected between the river water elevator pump 2 and air inlet injector 301 by water pipe.

The river purifying processing device, when in use, when river water elevator pump 2 open after, swiftly flowing sewage by into When gas blowout 301 mixing chamber of emitter, vacuum is formed in mixing chamber, large quantity of air is sucked by air intlet 302, air enters mixing chamber Afterwards, it is vigorously mixed at 301 trunnion of air inlet injector with sewage, air is cut into micro air bubble by sewage, under a certain pressure Air quickly dissolves in water, generates sharp impacts in air water and friction will be attached to the organic matter of surface particles simultaneously in sewage Separation forms gas, liquid, solid mixture, is discharged into 3 ontology of eddy flow oxygenator by 301 diffuser of air inlet injector and barrel is at cutting Enter eddy flow oxygenator 3 to eddy flow.It is centrifugal force that sewage containing air-liquid, solid mixture generates during swirling motion, centripetal Under the action of power and Fluid pressure, solid particulate matter is deposited to equipment cone bottom quickly, under pressure by bottom sand removing hole 303 Discharge can be directly discharged into city planting ductwork 7 by muddy water after grit water separator retains sand grains；And have the dissolved oxygen organic matter of micro air bubble Sewage rapid increase under cyclonic action is arranged from 3 top discharge outlet 304 of eddy flow oxygenator with the operating pressure not less than 0.2MPa Enter duct type static mixer 4.Eddy flow oxygenator 3 in addition to the sand grains in decontaminated water, because gas-liquid mixed is abundant, is passed rapidly and efficiently Matter effect is good, and the oxygen uptake rate of air microbubble is high, plays oxygenation, effective degradation of organic substances to sewage.Duct type is quiet State mixer 4 is the efficient mixing arrangement that dosing coagulant is made instantaneously to mix in pipeline, which is mix monomer element It is that two one group of combined crosswises are fixed in pipeline, is not required to additionaling power, water flow is generated by mixer is shunted in pairs, intersects and mix It closes and reversed eddy flow three acts on, the mixed effect of medicament and water is abundant, and head loss is less than 0.3m.Coagulant is existed by metering pump Coagulant access port 401 on 4 inlet tube of duct type static mixer is pumped into, and flocculation aid is by metering pump in duct type static mixing Flocculation aid access port 402 on device 4 is pumped into, and fierce collision, shearing in duct type static mixer 4, medical fluid, sewage and gas are more Further mixing.Gas-liquid mixed sewage through duct type static mixer 4 enters 5 bottom water-distributing device 510 of river clarifier, into Row water distribution uniformity, water velocity reduce, and slowly enter high concentration coagulation area, carry out thorough coagulating, floc particle by Gradually formed, under the action of waterpower and dissolved air water, in sewage based on microorganism, the suspended matter of easy floating that density is small Rise after coagulating with water flow, the effect through I and II settling zone, work of the heavy bulky grain wadding body of density ratio water in gravity It is slid down under, while the wadding body slid is under the hydraulic action of water conservancy diversion, automatically into the sludge hopper of river clarifier 5, It is discharged through automatic sludge discharger 511, is discharged into city by sludge-drainage time control 512 timing of automatic valve of setting by PLC control system Political affairs pipe network 7, the partial density flocs float lighter than water to top supernatant area 503 forms dross in the water surface, such as the bath class in sewage The dross that organic matter is formed, dross is discharged into collection mud sump or nearest city planting ductwork 7 after the collection of scum collector 504, to prevent from floating Slag escapes with water flow and is equipped with scum board 506 after top effluent overflow weir water plate 505；The a small amount of and watertight contained in the clear water of top It spends essentially identical small wadding body and enters filtering area 507 with water flow, be filtered from top to down by filtering layer, the small wadding in water Body is intercepted by filtering layer, is filtered.Filtered clear water is collected to the clear water zone of bottom of device, and is returned at the top of device by communicating pipe Filtered water tank, and it is discharged into downstream river course 6 from filtered water tank water outlet 509, sewage filters filtering after a certain period of time by filter layer The resistance of layer is gradually increased, and when filter pressure rises to water level close to 5 top water level of river clarifier, that is, is started by automatic anti- 508 automatic back-washing of cleaning device is stored under the water level static pressure of top filtered water tank in filtering area and accelerates backwash rapidly, clear in device Water is returned according to path opposite direction is operated normally, and starts to backwash filter layer when clear water passes through filtering area, when clear When pool water level decreasing to certain water level, it is automatically stopped backwash, backwash water outlet is discharged into city planting ductwork 7.

Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic It is equivalently replaced, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on, It should be included within the scope of protection of this utility model.
