Description
Technical field
The invention belongs to water treatment field more particularly to a kind of filler oxidation ditch suitable for samll cities and towns cage filler and
Its ciculation fluidized method.
Background technology
Microculture needs 30 days or so time in the prior art, and the samll cities and towns area in China is generally deficient of at sewage
The cost is relatively high for the professional technician of reason, engineering debugging and operation early period, to solve facility startup and sludge training early period
The problem of supporting is arranged cage filler, and carries out microorganism preculture, and cage filler can quickly start integration apparatus, contract significantly
The time of short microculture can be shorten to 5-7 days using the time of microculture after cage filler.
Invention content
Goal of the invention：In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of filling out suitable for samll cities and towns
Expect oxidation ditch cage filler.
Another object of the present invention is to provide a kind of cycles of the filler oxidation ditch cage filler suitable for samll cities and towns
Fluidizing method.
Technical solution：In order to reach foregoing invention purpose, the present invention is such completion：It is a kind of suitable for samll cities and towns
Filler oxidation ditch cage filler, including three-dimensional cylindrical frame, it is empty to form stereoscopic column shape for connection perforation net on three-dimensional cylindrical frame
Chamber, three-dimensional column cavity inside place floating stuffing；It is set below three-dimensional cylindrical frame there are two symmetrical adjutage, two symmetrical
Adjutage between be connected with bottom plate, place film-type aeration tube on bottom plate.
Further, the filling proportion of the floating stuffing is 60-the 80% of three-dimensional column cavity volume, too low filling
Cause the fluidisation of filler uneven than regular meeting, efficiency is low, and excessively high filling proportion can cause filler to accumulate to form dead zone on top.
Further, the top of the three-dimensional cylindrical cavity and the deflector that the angle of one of side wall is 1/4 circular arc,
The accumulation and acceleration of filler are internal ciculation fluidized in order to prevent, the downslide convenient for filler and fluidisation.
Further, three-dimensional column cavity bottom side corresponding with deflector is equipped with boring aeration pipe.
Further, the aeration quantity of the boring aeration pipe is 2-4m3/m2.h, floating stuffing is met in cage babinet
Interior is even fluidizing.
Further, the bubble diameter that the boring aeration pipe exposes is 0.8-1.2mm, and tiny bubble can improve
Dissolved oxygen in aerobic tank reduces the aerobic zone aeration quantity in non-filler region, to save energy consumption.
Further, the hole of the perforation net is laser punching.
Further, the aperture in the hole of the perforation net is 6-10mm, is on the one hand so that filler is not lost in, on the other hand
It is to prevent filler card in hole intraocular, and for it is with optimum flow rate and minimum resistance that uniform fluid flow, which passes through cage filler,
Power.
Further, the three-dimensional cylindrical frame is cylindrical body or square body frame.
A kind of filler oxidation ditch suitable for samll cities and towns ciculation fluidized method of cage filler, includes the following steps, will
The angle of the top of three-dimensional cylindrical cavity and one of side wall is set as the deflector of 1/4 circular arc, at three-dimensional cylindrical cavity bottom
Portion side corresponding with deflector is equipped with boring aeration pipe, and the aeration intensity of control punch aeration tube is in 2-4m3/m2.h、
The bubble diameter exposed is 0.8-1.2mm；Floating stuffing is positioned in the three-dimensional cylindrical cavity, the packing ratio of floating stuffing
Example is 60-the 80% of three-dimensional column cavity volume, and floating stuffing is located in cage, is exposed in horizontal plug-flow, hydraulic mixing and aeration tube
Circulated under the action of gas, floating stuffing to when flowing to three-dimensional cylindrical cavity top, glide under the action of deflector and
Fluidisation, recycles under boring aeration pipe aeration effect upward when slipping down to lower section, constantly move in circles, and floating stuffing mutually it
Between, floating stuffing and perforation net between constantly rub and collide.
Beneficial effects of the present invention：Compared with traditional technology, the invention has the advantages that：
1, the domestication cultivation cycle of microorganism fungus kind is short, be greatly saved the debugging of samll cities and towns oxidation ditch engineerings and operation early period at
This；
2, the sludge quantity in biochemistry pool is improved, while increasing the efficiency of aerobic nitrification；
3, cage filler generally cage construction, floating stuffing are located in cage, and are aerated in horizontal plug-flow, hydraulic mixing and bottom
Under the action of circulate, and pass through between filler and filler and perforation net between friction, collision effect realize biomembrane
Replacement, it is ensured that the normal growth of filler surface microorganism is bred.During operation, floating stuffing is respectively positioned on inside cage construction,
Compared with conventional fillers arrangement, for floating stuffing to other facilities in raceway groove, destruction is relatively small, can reduce to aeration
The protection requirement of the sensing units such as head, blender, cable, instrument or equipment.
