For the shortcoming that oxidation ditch floor space is large, the stereoscopic circulation integrated oxidation ditch technology of exploitation, the purification of the aeration of conventional oxidation ditch and the precipitation of mixed solution/be separated merge integrally by it, achieve mud without pump reflux; Change the plane circulation of conventional oxidation ditch into stereo circulating, this technology decreases the operation energy consumption of floor space and backflow compared with conventional oxidation ditch technology.
The sludge reflux of stereoscopic circulation integrated oxidation ditch is gordian technique unit, and how providing the power of backflow to form automatic back flow and how controlling sludge reflux is the key issue needing to solve.Based on this, invent a kind of stereoscopic circulation integrated oxidation ditch solid-liquid separator, for strengthening the effect of solid-liquid separation.
Summary of the invention:
The invention provides a kind of stereoscopic circulation integrated oxidation ditch solid-liquid separator, is the key equipment of stereoscopic circulation integrated oxidation ditch, effectively can solve the dynamical problem of sludge reflux and control the inlet of muddy water.
Described stereoscopic circulation integrated oxidation ditch solid-liquid separator, be connected with the tap drain of stereoscopic circulation integrated oxidation ditch, this stereoscopic circulation integrated oxidation ditch solid-liquid separator comprises solid-liquid separator casing, the mixed solution being positioned at solid-liquid separator casing enters weir, pipeline, sludge reflux mouth and the underwater propeller be arranged in tap drain, described mixed solution enters the top water surface site that weir is arranged on the joint face of solid-liquid separator casing and tap drain, described mixed solution enters weir is provided with and leads to the pipeline of solid-liquid separator casing away from tap drain end, described sludge reflux mouth is positioned at solid-liquid separator casing and is connected with tap drain the bottom in face, described underwater propeller is arranged in tap drain, be positioned at the front of sludge reflux mouth.
It is adjustable weir that described mixed solution enters weir, weir plate adjustable-height, is controlled the inlet of muddy water by regulating weir plate height.Enter mixed solution in weir by pipeline flow to solid-liquid separator casing and tap drain away from end, and mixed solution is flow to solid-liquid separator casing and tap drain by pipeline can prevent and treat solid-liquid separator rear end mud do not flow away from holding.
The obliquity of described pipeline is 30-60 degree, and distance solid-liquid separator casing and tap drain are away from the limit wall 0.5-2m held.
The operation steps of described stereoscopic circulation integrated oxidation ditch solid-liquid separator is as follows:
1, the muddy water mixed solution of tap drain enters weir by mixed solution, through Cemented filling to solid-liquid separator casing and tap drain away from end, its flow is controlled by the height of weir plate;
2, muddy water is after solid-liquid separator is separated, and precipitating sludge is back to tap drain by sludge reflux mouth, and underwater propeller promotes water (flow) direction away from solid-liquid separator, provide the power that precipitating sludge refluxes, and power is controlled.
Beneficial effect:
1, stereoscopic circulation integrated oxidation ditch solid-liquid separator system construction of the present invention is succinct, and operation is very simple with maintenance;
2, stereoscopic circulation integrated oxidation ditch solid-liquid separator of the present invention can save mud scraper, reduces investment outlay;
3, muddy water inlet and backflow power all controlled, improve stability and the efficiency of solid-liquid separator.

Embodiment:
Embodiment 1: a kind of stereoscopic circulation integrated oxidation ditch solid-liquid separator
Stereoscopic circulation integrated oxidation ditch solid-liquid separator II is connected with stereoscopic circulation integrated oxidation ditch tap drain I.
Described stereoscopic circulation integrated oxidation ditch solid-liquid separator II enters weir 1, pipeline 2, precipitating sludge refluxing opening 3 and underwater propeller 4 by solid-liquid separator casing 5, mixed solution and forms.
Mixed solution enters weir 1 and is positioned at solid-liquid separator casing 5 and is connected with stereoscopic circulation integrated oxidation ditch tap drain I the top water surface site in face, for adjustable weir, weir plate adjustable-height, enter mixed solution in weir by pipeline 2 flow to solid-liquid separator casing 5 and tap drain away from end, the gradient of pipeline 2 is at 45 degree, and distance solid-liquid separator and tap drain are away from holding limit wall 1m.
Precipitating sludge refluxing opening 3 is positioned at solid-liquid separator casing 5 and is connected with stereoscopic circulation integrated oxidation ditch tap drain I basifacial, and up crack from the bottom of pond, the width cracked is 1/15 of the depth of water.In stereoscopic circulation integrated oxidation ditch tap drain I, underwater propeller 4 is installed in the front end of refluxing opening 3, and it is away from solid-liquid separator casing 5 that underwater propeller 4 promotes water (flow) direction.
