Description
Technical field
The present invention relates to a kind of bio-reactor, be specifically related to a kind of ecological type membrane bioreactor, be particularly useful for processing and the reuse of the high sewage of organism and nutritive substance concentration, belong to water-treatment technology field.
Background technology
Contain a large amount of organism and nutritive substance in the sanitary sewage, this class sewage also can cause the huge waste of water resources if just directly draining into natural water body without effective processing not only pollutes the environment, is detrimental to health.Membrane bioreactor has advantages such as biodegradability is strong, effluent quality good, floor space is little, surplus sludge volume is few, yet the existence that film pollutes has seriously limited applying rapidly of this technology.
Summary of the invention
The objective of the invention 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 the aeration tank, transform traditional membrane bioreactor as the 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, the sewage after the processing can be used for spraying road, afforests, flushes the toilet etc.For Rural areas far away, distance municipal sewage plant because can handle nearby sewage, reuse nearby, this technology has more wide application prospect.
The objective of the invention is to be achieved through the following technical solutions: a kind of ecological type membrane bioreactor, this reactor comprises a housing, and the aeration tank is arranged in the housing; Described housing has water inlet pipe, rising pipe and air-supply duct and the shore pipe that is connected with housing outward, it is characterized in that: be mounted with membrane module in the described housing, membrane module is submerged in the water; Described membrane module is micro-filtration membrane module or hyperfiltration membrane assembly, and the position is equipped with aeration head at the bottom of pond below the membrane module; Cultivating in the described aeration tank has 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 the film water-out manners is suction type or gravity type boat davit.
Cultivating in the described aeration tank has active sludge and kind to be implanted with waterplant, and described waterplant is emergent, submerged plant, pleuston or floatingleaved plant, organism and nutritive substance in the former water of the common degraded of the waterplant of active sludge and plantation.
Described air-supply duct is delivered to aeration head with air.
Advantage of the present invention is: the ecological type membrane bioreactor can effectively be finished biological degradation and mud-water separation, the processing efficiency height, and effluent quality is good: the activated sludge concentration height in the membrane bioreactor, biodegradability is strong.In addition, waterplant can further be removed organism and the nutritive substance in the water, therefore, compares with traditional membrane bioreactor, and biodegradability of the present invention is stronger, and effluent quality is better; The preventing membrane pollution ability is strong: the present invention can more effectively remove the dissolved organic matter in the former water, and this material has been proved to be one of important substance that causes the film pollution.In addition, because the introducing of waterplant, the active sludge physicals in the reactor can improve, and the filtration resistance of film surface cake layer can be minimized, and therefore, the present invention effectively controlling diaphragm pollutes.
Description of drawings
Below in conjunction with drawings and Examples the present invention is done and to describe in further detail:
Fig. 1 is the structural representation of ecological type membrane bioreactor of the present invention;
Among 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 by steel plate, and 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 the aeration tank 2, and membrane module 4 is submerged in the water.
Pending former water enters aeration tank 2 through water inlet pipe 1.
Cultivating in the aeration tank 2 has active sludge, the organism in the pending former water and other pollution substances to obtain removing under the acting in conjunction of active sludge and waterplant.
Mixed solution in the aeration tank 2 realizes that after membrane module 4 filters solid, liquid separates, 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 be controlled water inlet, water outlet, aeration, spoil disposal of reactor etc. automatically.
The processing mechanism of ecological type membrane bioreactor of the present invention:
A. activated sludge process
Cultivating in the aeration tank has certain density active sludge, perches a large amount of microorganisms on the active sludge, and under the metabolism of microorganism, the organism in the water and nutritive substance can obtain degraded.
B. phytoremediation technology
Waterplant can directly absorb pollution substance in the water and the component of assimilate into self.In addition, root system of plant is perched a large amount of microorganisms, and under the metabolism of these microorganisms, the organism in the water and nutrient concentrations can be minimized.In addition, the specific surface area of root system of plant is bigger, and adsorptive power is stronger, also is conducive to the removal of pollution substance.
C. membrane sepn effect
Under the sieving effect, but the equal tunicle of the material that the particle diameter ratio membrane pore size is big in the water is held back.Therefore, the mixed solution in the aeration tank is flowed through behind the membrane module, and effluent quality can further improve.
The working mechanism of ecological type membrane bioreactor of the present invention:
After entering aeration tank 2 from the pending former water of water inlet pipe 1, under the acting in conjunction of active sludge and waterplant 3, organism in the former water and nutritive substance can effectively be removed, and mixed solution realizes that after membrane module 4 filters solid, liquid separates, and is obtained the final outflow water of reactor by rising pipe 8.Aeration head 5 is installed in membrane module 4 belows, and the bubble that aeration head 5 discharges can provide essential dissolved oxygen for microorganism, can stir water body again, and matrix is fully contacted with waterplant with active sludge, can also wash away the film surface, suppresses film and pollutes.Air-supply duct 6 provides air to aeration head 5, and the excess sludge that reactor produces is regularly discharged by shore pipe 7.
Ecological type membrane bioreactor of the present invention can be used for the purifying treatment of sewage, and the regeneration that is particularly useful for the high sewage of organism and nutritive substance concentration is handled.
Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention is not limited to above-mentioned giving an example, those skilled in the art, and in essential scope of the present invention, the variation of making, remodeling, interpolation or replacement all should belong to protection scope of the present invention.
