Description
Technical field
The utility model relates to a kind of bio-reactor, is specifically related to a kind of ecological type membrane bioreactor, is particularly useful for the treatment and reuse of the sewage that organism and nutritive substance concentration are high, belongs to water-treatment technology field.
Background technology
In sanitary sewage, contain a large amount of organism and nutritive substance, if just this class sewage directly drains into natural water body and not only pollutes the environment, is detrimental to health without effectively processing, also can cause the huge waste of water resources.Membrane bioreactor has the advantages such as biodegradability is strong, effluent quality good, floor space is little, surplus sludge volume is few, but the existence that film pollutes has seriously limited applying rapidly of this technology.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art part, a kind of ecological type membrane bioreactor is provided, phytoremediation technology and membrane Bio-reactor Technology are organically combined, by planting aquatic plants in aeration tank, transform traditional membrane bioreactor as ecological type membrane bioreactor, not only can further improve reactor to organic biodegradability, raising effluent quality, effectively controlling diaphragm pollutes.Its technical process is short, floor space is little, simple to operate, easy to maintenance, sewage after treatment can be used for spraying road, afforests, flushes the toilet etc.For for compare Yuan Rural areas, municipal sewage plant, owing to can sewage be processed nearby, reuse nearby, this technology has more wide application prospect.
The purpose of this utility model is achieved by the following technical solution: a kind of ecological type membrane bioreactor, and this reactor comprises a housing, has aeration tank in housing; Described housing has water inlet pipe, rising pipe and the air-supply duct and the shore pipe that are connected with housing outward, it is characterized in that: in described housing, be mounted with membrane module, membrane module is submerged in water; Described membrane module is micro-filtration membrane module or hyperfiltration membrane assembly, and below membrane module, at the bottom of pond, position is provided with aeration head; In described aeration tank, cultivate and have active sludge and kind to be implanted with waterplant.
The pattern of described membrane module film is hollow-fibre membrane or flat sheet membrane, and film water-out manners is suction type or gravity type boat davit.
In described aeration tank, cultivate and have active sludge and kind to be implanted with waterplant, described waterplant is emergent, submerged plant, pleuston or floatingleaved plant, organism and nutritive substance in the former water of the common degraded of waterplant of active sludge and plantation.
Air is delivered to aeration head by described air-supply duct.
The utility model has the advantages that: ecological type membrane bioreactor can effectively complete biological degradation and mud-water separation, and processing efficiency is high, and effluent quality is good: the activated sludge concentration in membrane bioreactor is high, and biodegradability is strong.In addition, waterplant can further be removed organism and the nutritive substance in water, and therefore, compared with traditional membrane bioreactor, biodegradability of the present utility model is stronger, and effluent quality is better; Preventing membrane pollution ability is strong, can more effectively remove the dissolved organic matter in former water, and this material has been proved to be one of important substance causing film pollution.In addition, due to the introducing of waterplant, the active sludge physicals in reactor can improve, and the filtration resistance of film surface cake layer can be minimized, and effectively controlling diaphragm pollutes.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model ecological type membrane bioreactor;
In Fig. 1: 1. water inlet pipe; 2. aeration tank; 3. waterplant; 4. membrane module; 5. aeration head; 6. air-supply duct; 7. shore pipe; 8. rising pipe; 9. housing.
Embodiment
As shown in the figure: housing 9 is made up of steel plate, planeform is rectangle, and hull outside connects water inlet pipe 1, air-supply duct 6, shore pipe 7, rising pipe 8, and enclosure interior is aeration tank 2, settles waterplant 3 and membrane module 4 in aeration tank 2, and membrane module 4 is submerged in water.
Pending former water enters aeration tank 2 through water inlet pipe 1.
In aeration tank 2, cultivate and have active sludge, organism and other pollution substances in pending former water are removed under the acting in conjunction of active sludge and waterplant.
Mixed solution in aeration tank 2 is realized solid, liquid and is separated after membrane module 4 filters, and is obtained the final outflow water of reactor by rising pipe 8.
Shore pipe 7 is used for getting rid of the excess sludge that reactor produces.
The configurable automatic control system of this reactor, can control water inlet, water outlet, aeration, spoil disposal of reactor etc. automatically.
The processing mechanism of the utility model ecological type membrane bioreactor:
A. activated sludge process
In aeration tank, cultivate and have certain density active sludge, perch a large amount of microorganisms on active sludge, under the metabolism of microorganism, the organism in water and nutritive substance can be degraded.
B. phytoremediation technology
Waterplant can directly absorb the pollution substance in water and assimilate into the component of self.In addition, root system of plant is perched a large amount of microorganisms, and under the metabolism of these microorganisms, the organism in water and the concentration of nutritive substance can be minimized.In addition, the specific surface area of root system of plant is larger, and adsorptive power is stronger, is also conducive to the removal of pollution substance.
C. membrane sepn effect
Under sieving effect, the material that in water, particle diameter ratio membrane pore size is large all can be held back by tunicle.Therefore, the mixed solution in aeration tank is flowed through after membrane module, and effluent quality can further improve.
