Abstract
An application of luffa in preparing the dynamic membrane used in dynamic-membrane bioreactor is disclosed. Its advantages are high water permeability, low cost and biodegradable.
Description
Technical field
The present invention relates to a kind of application of netural plant luffa network.
Background technology
Sponge gourd is the annual plant that climbs up by holding on to, and all there is cultivation all parts of the country.Except that sponge gourd meat was edible, because Vegetable Sponge of Luffa (claiming chalina again) is the network body of eclipsed form, Vegetable Sponge of Luffa can be used for shoe-pad class, bath article class, as: 1, patent No. CN00100043.8, denomination of invention: health-care medical shoe pad of vegetable sponge and preparation method thereof.2, the patent No.: CN91220236.X, denomination of invention: natural Skin care bath towel belongs to daily bath article.
Present known bioreactor of dynamic membrane (or claims membrane bioreactor, mainly be divided into integral type, split type two big classes) be mostly that the organic polymer membrane module of bioreactor system and synthetic constitutes, membrane module (or claiming Dynamic Membrane) is by the vacuum pump suction or utilize the head pressure reduction water outlet on membrane module top.Common bioreactor of dynamic membrane has two main drawbacks: 1, adopting the organic polymer material of artificial preparation is base material, the outside seals with bolting silk, cause the dynamic membrane filtering resistance big, aquifer yield is little, price is comparatively expensive, the aged filter material forms secondary pollution, and its treatment and disposal is difficulty very, to the environment structure potential hazard.2, weak, the heavy contamination of film of the backwash rate of split type MBR film, film permeability rate are lower, and the unit surface membrane flux generally only is 50-80L/m
2H.
Present known filtering material adopts the difference of raw material according to it, can be divided into inorganic filtrate, organic polymer filtrate and plant type filtrate, common inorganic filtrate has haydite, coke, quartz sand, gac, expansion silico-aluminate etc., and the organic polymer filtrate has polystyrene, polyvinyl chloride, polypropylene etc.The organic polymer filtrate is easily aging to come off, and easily pollutes, and easily stops up, and costs an arm and a leg, and forms secondary pollution easily.Quartz sand in the natural inorganic filtrate is because density is big, and specific surface area is little, porosity is little, when effluent stream during through filtering layer resistance very big, biomass is few, so filter loading is not high, head loss is big, that uses now is few.Light ceramic filtrate specific surface area and porosity are big, biomass is big, so filter loading is big, head loss is less, the convenience, cheap, domestic more to its research of drawing materials.The plant type filtrate is mainly based on the dried shell of nuts such as nut-shell.
Summary of the invention
The object of the present invention is to provide a kind of application of netural plant luffa tubular fibre material, this netural plant luffa tubular fibre material is applied in the bioreactor of dynamic membrane as Dynamic Membrane, has film permeability rate height, characteristics that cost is low.
To achieve these goals, technical scheme of the present invention is: a kind of application of netural plant luffa tubular fibre material, it is characterized in that: netural plant luffa mature fruit or half ripe fruit are processed into Vegetable Sponge of Luffa, are that the Dynamic Membrane of base material is applied in the bioreactor of dynamic membrane with the Vegetable Sponge of Luffa.
Because Vegetable Sponge of Luffa is the network body structure of eclipsed form, netural plant luffa tubular fibre material of the present invention (being Vegetable Sponge of Luffa) is applied in the bioreactor of dynamic membrane as Dynamic Membrane, have following characteristics: 1. renewable performance: mature fruit or half ripe fruit by netural plant luffa make, preparation cost is cheap, belongs to renewable resources; 2. has good biodegradable performance: when being used as the Dynamic Membrane of biological sewage treatment, after passing through certain duration of service, can grow aerobic cellulose-decomposing bacterium and anaerobism gemma clostridium automatically at netural plant luffa tubular fibre material surface, be CO with this material breakdown
2And H
2Materials such as O (when being used for other field and need changing, can add and contain aerobic cellulose-decomposing bacterium or anaerobism gemma clostridial active sludge, finish its thorough degraded) can not form secondary pollution; 3. good microorganism colonization performance: because this netural plant luffa tubular fibre material has good vegetable active, microorganism is easy to stick to its surface, can effectively reduce the microorganism colonization time, reduces the operation control accuracy, operation energy consumption is lower, and performance is better; 4. be the network body structure of eclipsed form, its surface irregularity, many micropores, the intensity height, porosity is big, specific surface area is big, as Dynamic Membrane, its permeability rate height, it is low to handle energy consumption; 5. the chemistry of this netural plant luffa tubular fibre material and physical stability are good, compare with the Dynamic Membrane of regular shape such as polyvinyl chloride, have advantages such as functional; 6. the flow-shape of this netural plant luffa tubular fibre material is good, filtration cycle long, back flushing is carried out easily, retaining power is strong.
