Abstract
The present invention discloses a biofilm aeration reactor, which comprises a reactor, wherein the lower portion of the reactor is provided with a water inlet, the top portion is provided with a water outlet, the bottom portion is provided with a deslagging port, the internal of the reactor is divided into two zones through a separation plate, the biological reaction zone 1 is arranged on the lower portion and is filled with a first-stage microbial filler, the biological reaction zone 2 is arranged on the upper portion and is filled with a second-stage microbial filler, and the top portion of the reactor is provided with an aeration pipe. According to the present invention, the two groups of the microbial fillers are added, such that the water treatment can achieve the new standard, the two microbial fillers can select the aerobic microorganisms, and can further select the aerobic microorganisms and the anaerobic microorganisms; the two groups of the microorganisms are used to treat the water, such that the COD is significantly lower than the COD of the sewage treated by the one microorganism; and the size of the reactor is not different from the traditional reactor size, such that the treatment effect is substantially improved while the occupation area is not expanded.
Description
Technical field
The invention belongs to field of Environment Protection, be specifically related to a kind of biofilm aeration reactor.
Background technology
MBBR (MBBR) is directly added in aeration tank as microbic activity carrier using the floating stuffing of proportion close to water, rely on the castering action of the aeration in aeration tank and current and be in fluidized state, when microorganic adhesion is on carrier, floating carrier moves freely along with the convolution inverting action of mixed solution in reactor, thus reaches the object of sewage disposal.As a kind of technique that the activated sludge process of suspension growth and the biomembrance process of apposition growth combine, current MBBR reactor has both advantages concurrently, but also also exist that filler easily runs off, filler easily piles up at water outlet problems such as causing filler distribution uneven.
Summary of the invention
Goal of the invention: the object of the invention is to, provides a kind of biofilm aeration reactor for the deficiencies in the prior art.
Technical scheme: in order to achieve the above object, the present invention is specifically achieved like this: a kind of biofilm aeration reactor, comprise reactor, reactor lower part is provided with water inlet, top is provided with water outlet, bottom is provided with slag-drip opening, inside reactor is by being divided into two regions by dividing plate, below for biological respinse one district, in be filled with one-level microbe stuffing, top be biological respinse two district, in be filled with secondary microbe stuffing, described reactor head is provided with aeration tube.
Wherein, described one-level microbe stuffing diameter is greater than secondary microbe stuffing diameter.
Beneficial effect: the present invention is compared with conventional art, water treatment is made to reach a new standard by adding 2 groups of microbe stuffings, two kinds of microbe stuffings all can choose oxygen animalcule, also can select a kind of is anaerobion for aerobic microbiological is another kind of, utilize 2 groups of microbiological treatment water bodys, COD is starkly lower than a kind of sewage of microbiological treatment, meanwhile, reactor is still as good as with traditional size, while not expanding floor space, substantially increase treatment effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
A kind of biofilm aeration reactor as shown in Figure 1, comprise reactor 1, reactor 1 bottom is provided with water inlet 2, top is provided with water outlet 3, bottom is provided with slag-drip opening 4, reactor 1 inside is divided into two regions by by dividing plate 5, below for biological respinse one district 6, in be filled with one-level microbe stuffing 61, top for biological respinse two district 7, in be filled with secondary microbe stuffing 71, described reactor 1 top is provided with aeration tube 8; Described one-level microbe stuffing 61 diameter is greater than secondary microbe stuffing diameter 71.
