Description

A kind of automatically cleaning fluidized bed bioreactor
Technical field
The present invention relates to microdisk electrode technical field, especially a kind of automatically cleaning fluidized bed bioreactor.
Background technique
Microalgae is photosynthetic autotrophs biology, is widely distributed in tellurian fresh water, ocean and various soil, has growth Rapidly, photosynthetic efficiency is high, adaptable and the features such as pass through vegetative propagation.Microalgae can be using luminous energy, CO2, organic in waste water The substances such as carbon, ammonia nitrogen, organic phosphorus are carbon source, nitrogen source and phosphorus source, and adsorb heavy metal purification waste water;Also it can absorb in atmosphere The gases such as CO2 generate O2 and purify air as own metabolism carbon source;Contain a variety of high added value biological active matters in microalgae simultaneously Matter, such as polyunsaturated fatty acid, algal polysaccharides, algocyan, astaxanthin, carrotene have antibiotic, anti-cardiovascular disease Medical values and the healthcare functions such as disease, strengthen immunity, antitumor, anti-radiation, anti-mutation and anti-AIDS, to human diseases It prevents, treats and healthcare function.Microalgae is as industries such as feed, medical treatment, bioengineering, food, light industry, bio-fuels Important source material, industrialization production are more paid attention to by people with utilization.
Activated sludge is to modernize depth biological treatment in sewage treatment plant necessarily to use, containing big in activated sludge The microorganism of amount, including bite phosphorus bacterium, nitrite bacteria, nitrobacteria etc., sewage treatment plant always exists asking greatly for three aspects Topic, the i.e. energy of 1. aerobic tanks aeration consumption, 60% or more sewage treatment plant;2. the expansion of activated sludge, increase of becoming morally degenerate Operation difficulty with it is professional;3. residual active sludge cross contain cause excess sludge processing cost increase with to the secondary of environment Pollution.At present almost 80% or more sewage treatment production there is problem above, research and develop new sewage treatment process, Reduce cost of sewage disposal and operation difficulty be need most at present exploration and research, this be also to environmental protection must It asks.
For the microalgae energy exploitation in terms of, current main direction of studying both domestic and external is to utilize microalgae processing waste water, micro- Algae all biological sequestration, micro-algae large-scale cultivation and high added value product extraction direction, and processing of the microalgae to waste water, scale Change in cultivation and the extraction of high added value product, has the following problems, 1. microalgaes need light that could convert CO2 and carbon source to O2 carries out biological sequestration;2. microalgae is limited to the COD degradation of sewage, the COD more than sewage after a certain period of time can also become in increasing Gesture, but to nutrient such as N, P etc., degradation effect is prominent;3. microalgae is smaller, and is difficult to settle, this also results in microalgae and exists The cost collected under suspended state will greatly increase, this is also the main reason for restricting micro-algae large-scale cultivation;4. microalgae is handled The residence time is longer in water required for waste water, and cannot remove microalgae well after having handled sewage, cause water body turbidity, Coloration etc. increases;5. the biological sequestration amount of microalgae is lower, because the CO2 under suspended state in air needs to enter from air dielectric Liquid culture medium free diffusing enters frustule, can just be absorbed fixed later and photosynthesis occurs under the action of light, will CO2 is converted into O2, but the solubility of CO2 in a liquid is lower, to improve the solubility of CO2 in the medium, must be just Culture medium is in alkalinity, but since the pH range of microalgae suitable growth is in 6-10 or so, so the biological fixation of CO2 is still by very big It restricts and influences.
Currently, microalgae can be combined with the processing of sewage and industrial waste gas, closed while handling sewage and industrial waste gas At high assignments substance, toxigenic capacity is reduced.Research direction be mainly probe into microalgae cultural method and different Waste types with not Lotus root with microalgae type is closed, for how to realize waste liquid fermentation production integrated with microdisk electrode, recycling, excess sludge surplus etc. The problems such as on, pay close attention to it is less, therefore, it is necessary to propose a kind of automatically cleaning fluidized bed bioreactor realize waste liquid fermentation and The integration production such as microdisk electrode, recycling and excess sludge surplus purifies useless water and air to reduce production cost.
