Embodiment
In order to illustrate more clearly of content of the present utility model, the drawings and specific embodiments will be combined and described in detail.
As shown in figure 1, a kind of small-sized biological membrane reactor of this implementation, for handling the decentralized point pollution such as country sewage
Water body, including buried small contact oxidation pond, each contact-oxidation pool include being embedded in the outer tank 3 of subsurface and position in the inner
The inner cylinder 2 in portion, the inner cylinder 2 is fiberglass cylinder, the top cylinder 7 of small diameter that cylinder includes being sequentially connected, transition
Middle part cone cylinder 8, larger-diameter bottom cylinder 9, top cylinder 7 are that open form is fixed with the top of outer tank 3 with bolt, bottom circle
9 lower ends of cylinder are open form, are connected with fixed plate with outer tank 3.
The bottom cylinder 9 is catalytic oxidation tank main body, and top is connected with water inlet pipe 1, and inner vertical is provided with filler 4,
Lower section has aerator 5, has outlet pipe 6 at the top of the outer tank, highly essentially identical with the water inlet pipe.
The setting of glass reinforced plastic inner cylinder 2 causes this contact-oxidation pool to have similar pulling flow type flow pattern, adds the walking of sewage
Length, it is to avoid the sewage that flows into from water inlet pipe 1 is unprocessed just directly to discharge from outlet pipe 6, drastically increases processing and imitates
Rate.
The outer tank 3 is cylinder glass cylinder of steel body, is produced using fiberglass Mechanical entanglement burning into sand forming technique, is by interior
Outer layer glass steel construction and the three-decker of middle burning into sand formation, the firm of fiberglass tank body is substantially increased by burning into sand
Degree, substantially increase the anti-earthwork lateral pressure ability of outer tank 3, under equality strength, tank body wall thickness reduce, reduce equipment into
This.
Gap between the outer tank 3 and inner cylinder 2 is H, and the span of this value is 120~200mm, meets upflow velocity
It is required that, it is reasonable to set, and the mixture of sludge and water can smoothly enter next structures, for example next stage contact-oxidation pool or
Sedimentation basin, without sludgd deposition in the bottom of outer tank 3 or the phenomenon of blocking outlet pipe 6.
The filler 4 is helical packing, is through machine by the special fibre with strongly hydrophilic and good sludge adhesion property
Tool processing weaving is formed, and shape is in the shape of a spiral.Helical packing biofilm is fast, removes pollutant ability by force, anti-variation water quality ability is strong,
And with efficient denitrogenation, dephosphorization ability, therefore helical packing drastically increases the removal ability of pollutant.
The aerator 5 is boring aeration pipeline, is UPVC pipelines, wherein aeration supervisor is provided with downward 45 ° of outlet
Hole, is arranged on the lower section of helical packing positioned at bottom in outer tank 3.Not only oxygen supply is abundant for the boring aeration pipeline, and to life
Thing film serves agitaion, accelerates the renewal of biomembrane, improves biomembrane activity, while being aerated the turbulent flow formed, makes
The biomembrane being fixed on filler 4 can continuously, equably with sewage be in contact so that bio-contact oxidation is more abundant.In addition,
Because the perforate of boring aeration pipe is located at the obliquely downward of aeration tube, therefore the sludge of the tank bottom of outer tank 3 can fully be stirred evenly, tank bottom without
Sludgd deposition, thus in the absence of sludge bulking.
Water inlet pipe 1 and outlet pipe 6 in the contact-oxidation pool are glass reinforced plastic pipe.
In addition, the small-sized biological membrane reactor in this implementation may include multiple small contact oxidation ponds, pass through the string of pond body
Connection formed one section of contact-oxidation pool, two sections, three sections even four sections so that processing after water outlet reach one-level B, one-level A etc.
National standard.
The operation principle of the small-sized biological membrane reactor of the present embodiment is as follows：
Sewage is flowed into the bottom cylinder 9 of inner cylinder 2 by water inlet pipe 1 first, flows through the filler 4 for being fixed with biomembrane, with
The water level in the bottom that gravity drops to outer tank 3, outer tank 3 to gradually rise up to be further separated at the bottom opening of bottom cylinder 9
In the gap of inner cylinder 2 and outer tank and inner cylinder.Sewage carries out Aerobic Process for Treatment when contacting filler 4, under biomembrane effect in sewage
Biochemical composition carry out aerobic reaction, remove pollutant, while the bottom of outer tank 3 aerator 5 persistently be aerated, sewage is entered
Row Air Exposure, the oxygen of abundance is provided for aerobic reaction, promotes the stirring and renewal of biomembrane, maintains the activity of biomembrane,
Ensure treatment effeciency, and the sludge of the bottom of outer tank 3 is stirred evenly, tank bottom is without sludgd deposition.Finally, when the water level in gap
The height of outlet pipe 6 on the top of outer tank 3 is risen to, the sewage after processing is flowed out outside contact-oxidation pool through outlet pipe 6, into next section
Contact-oxidation pool or other processing ponds, until reaching requirement standard.
In summary, a kind of small contact oxidation pond of the present utility model is mainly used in the small of small-scale sewage and point pollution
Type sewage-treatment plant, can according to the characteristics of small-sized contaminant water, in the case where giving full play to biological contact oxidation process advantage,
Using advanced film oxidative treatment technique, and optimize apparatus structure, reduce cost, improve device service life, improve processing effect
Rate, efficiently solves small-scale sewage governing problem.
