Description

A kind of efficiently up-flow anisotropic flow inclined-plate clarifying basin
Technical field
The present invention relates to a kind of water treatment technology equipment, especially relate to a kind of efficiently up-flow anisotropic flow sloping plate deposition Pond.
Background technology
The sedimentation tank kind using sewage disposal has a lot, can be divided into flat flow, hard streaming, spoke from drainage flow mode Flow settling pond, but this sedimentation tank floor space is big, and deposition efficiency is the highest.Inclined-plate clarifying basin has removal efficiency height, stops Time is short, floor space is little etc. a little, and its hydraulic surface loading is 2 times of conventional precipitation pond.Traditional inclined-plate clarifying basin often exists Original Sewage Plant uses when expanding disposal ability transformation.But swash plate meeting cooperating microorganisms in tradition inclined-plate clarifying basin, to highly concentrated The mud-water separation poor effect of degree, effluent quality is unstable, is not suitable for using as second pond.Additionally, traditional water outlet triangle The scum silica frost on weir with current flow out, construct the best in the case of the problems such as short stream easily occur.
Summary of the invention
Because the drawbacks described above of prior art, the present invention provide a kind of efficiently up-flow anisotropic flow inclined-plate clarifying basin and Using method, this invention uses backwashing system, is sedimentation tank second pond in high impurity waste water and sewage disposal, adopts With Air Weir as sedimentation tank outlet system, prevent scum silica frost from flowing out with current, and avoid tradition effluent weir for construction not Good caused short stream etc..
The purpose of the present invention can be achieved through the following technical solutions:
A kind of efficiently up-flow anisotropic flow inclined-plate clarifying basin, described sedimentation tank includes sludge bucket, water distribution the most successively District, sloping plate deposition district and clear water zone, described sludge bucket is sequentially provided with a mud return line, a sludge reflux sky from bottom to up Trachea, a discharge pipeline, two sparge pipes and a set of backwash gas equipment;Described a set of backwash gas equipment level is positioned over dirt Above mud return duct;Described sloping plate deposition district be provided with some be parallel to each other, spaced swash plate;Described clear water zone is provided with sewage Overflow pipe and Air Weir;Described sewage overflow pipe can the preposition regulating reservoir of UNICOM or sump;Described Air Weir is positioned at swash plate and sinks Between shallow lake district and design water level.
Described Air Weir comprises four water inlet pipes, an air inlet/outlet and a total outlet pipe.
Described sludge bucket is in tetragonous cone table.
Vertically downward, discharge pipeline is provided with electromagnetism horizontal through sludge bucket, the pipe section outside sludge bucket to the described spoil disposal mouth of pipe Valve.
Described two sparge pipes are between the sludge reflux mouth of pipe and mud return line, and water-distributing gap is positioned at rectangle sedimentation tank and cuts The center in face.
The air hose of described backwash gas equipment uses two ends to interlock and wears φ 3 hole, and between hole, spacing is 200mm.
Swash plate oblique angle, described sloping plate deposition district uses 55 °, and the vertical interval of every piece of swash plate is 100mm.
Four water inlet pipe mouth horizontal vertical of described Air Weir are downward;Described outlet pipe uses the water inlet of reverse U shape vertical UNICOM Pipe and outlet pipe, outlet pipe is horizontal through body of wall.
The using method of described a kind of efficient up-flow anisotropic flow inclined-plate clarifying basin, its step is as follows:
Step (a): sparge pipe is intake 23 hours according to sedimentation tank design load, muddy water mixed solution is sufficient in water distributing area Mix homogeneously, enters sloping plate deposition district, and activated sludge sufficiently separates at this, and the mud after sedimentation is by under action of gravity progressively It is down to sludge bucket;
Step (b): the water inlet cycle is 23 hours, while water inlet, air inlet (giving vent to anger) mouth of Air Weir constantly extracts sky out Gas, causes the water inlet pipe of Air Weir and the fluid communication of outfall sewer, owing to whole Air Weir is positioned at below design water body, and muddy water Waste water up to standard after separation is discharged by outfall sewer.Sludge reflux air hose is passed through appropriate air, by the side of air stripping Formula operating sludge reflux;
Step (c): the whole cycle of cutting off the water remains 1 hour, air inlet (giving vent to anger) mouth of Air Weir is constantly extracted air out, is caused The water inlet pipe of Air Weir and the liquid cutout of outfall sewer, waste water up to standard stops outer discharge.Simultaneously, sparge pipe stops toward heavy The draining of pond, shallow lake.Cut off the water in the cycle first 15 minutes, keep and blast appropriate air toward backwash gas system, the deposit to swash plate district Rinse, prevent growing of microorganism.Cut off the water in the cycle latter 45 minutes, stop backwash gas system aeration so that mud is the most heavy Amass to sludge bucket.
Beneficial effects of the present invention: the present invention uses backwashing system, is that sedimentation tank is at high impurity waste water and sewage Second pond in reason, uses Air Weir as sedimentation tank outlet system, prevents scum silica frost from flowing out with current, and avoid tradition and go out Mill weir is for constructing bad caused short stream etc..
