Abstract
A method and system for biologically cleaning indoor air features that after the efficient composite photosynthesizing bacteria are cultured in photoreactor, they are pumped in an air cleaning equipment to clean the indoor air. Its advantaegs are high effect and no secondary pollution.
Description
Technical field
The present invention relates to a kind of method and indoor air-purification device of indoor air purification, particularly relating to a kind of is the method and apparatus of control techniques with the photosynthetic bacteria biology.
Background technology
The people all one's life nearly 70%-90% time spend indoor.Good and bad healthy and life, the work quality that directly influences people of IAQ.Because the enclosure effect of construction material, particularly along with raising energy-conservation, the temperature and humidity comfort requirement, the airtight degree of building constantly increases, and the room air pollution degree surpasses outdoor tens times and even hundreds of times.The IAQ problem is more and more paid close attention to by the government and the public.Therefore, air cleaning begins to be used to control room air pollution.
At present, indoor air purification method of having used and device mainly contain three classes: the one, and physical method and device thereof, according to the design of physical property method, have functions such as filtration, adsorption treatment impurity, the suspension in can partly purifying the air of a room and a small amount of harmful substance.But it is powerless to the odor smell in the room air, pathogen, virus and organic chemistry air pollution.Simultaneously, these adopt physical method to implement the product that purifies, slowly can be saturated until losing effect in filtration and adsorption process.The 2nd, on the basis of aforementioned physical property, functions such as electrostatic precipitation, anion generation, ozone generation have been increased, make it not only can smoke abatement and dust control, and functions such as part sterilization, sterilization are arranged, but still can not decompose the maximum organic pollution of human body harm.And anion combines the contaminant particles heavy ion one by one that can become certain polarity with dust and dirt in the air that pollutes, aggravated the harm of original airborne pollutant to human body on the contrary.Ozone exposure also is harmful to health.Multiple disease such as ozone exposure and lung cancer has necessarily gets in touch.The 3rd, photocatalysis method, catalyst is adopted nano material, based on polynary heterogeneous catalysis, in conjunction with hyperfiltration, make it change chemisorbed into by simple physical absorption, decompose while adsorbing, improved kind and the adsorption efficiency and the saturated capacity of absorption pollutant, can carry out the part catalytic decomposition indoor ammonia, hydrogen sulfide, aldehydes etc.Though but on the function of removing indoor harmful gas, improve to some extent, also not remarkable to the clean-up effect that the indoor degree of depth is polluted, can not desirablely solve the purification that the air organic matter pollutes.And the life-span of catalysis material also is very limited.Therefore, at present, the room air pollution purifying problem also lacks desirable method and apparatus and solves.
Summary of the invention
The object of the present invention is to provide the special biology of a kind of usefulness, promptly photosynthetic bacteria effectively solves the method and apparatus that room air pollution purifies.This method and apparatus is applicable to the various indoor place that various office office buildings, meeting room, hotel, school, hospital, cultural facility, commercial facility, wait (machine, ship hall etc.) and dwelling house etc. are established centralized air-conditioning.
Technical scheme of the present invention is formed (seeing Figure of description Fig. 1 and Fig. 2) by photosynthetic bacteria used for light reaction technology and device+photosynthetic bacteria air purifying process with device
1. select degraded air-polluting photosynthetic bacteria (Photosynthetic Bacteria) bacterial classification.This bacterium goes up ownership according to the BergeyShi Bacteria Identification handbook the 8th edition of publication in 1974 and is the luminous energy bacterial nutrition.Rhodospirillum (Rhodospirillum) and red false unit cell that this programme is chosen the thin Rhodospirillaceae of Rhodospirillales belong to (Rhodopseudomonas) two genus totally 15 kinds of integrated bacterial classifications of mixed high-efficient.

310 grams, sodium acetate 50 grams are dissolved in 1000 ml waters promptly.
This culture medium best prescription is formed (per hundred kilograms of culture medium consumptions): sodium acetate 900 grams, sodium propionate 90 grams, potassium dihydrogen phosphate 60 grams, diammonium hydrogen phosphate 90 grams, magnesium sulfate 20 grams, calcium chloride 50 grams, urea 30 grams, salt 10 grams, yeast extract 30 grams, 100 milliliters of trace element solutions.。The ratio of strain liquid and liquid medium is 1:1-1:10, is made into integrated photosynthetic bacteria nutrient solution.
3. the integrated photosynthetic bacteria nutrient solution that will prepare pumps into photosynthetic bacteria reaction unit (seeing Figure of description Fig. 2, Fig. 3) and cultivated 10-30 days.Reach absorbance 0.8-1.8, bacteria containing amount 500,000,000-1,000,000,000/ml becomes the air-cleaning function bacterium.
4. air-cleaning function bacterium liquid pump is gone into photosynthetic bacterium air cleaning unit, carry out indoor air filtration, degraded purification work according to photosynthetic bacteria air cleaning unit operation principle.The matching ratio of indoor air purification volume and function bacterium liquid is approximately 1m
3: 50-500ml.
5. to carry out general about 30 days of service time of air cleaning be one-period to the function bacterium in the photosynthetic bacteria air cleaning unit.As reach poor efficiency function bacterium standard, and promptly absorbance is reduced to below 0.6, and bacterial concentration then needs function bacterium liquid is upgraded below 200,000,000/ml.During renewal, poor efficiency function bacterium liquid pump is gone into device for storing liquid, the efficient function bacterium liquid pump of photosynthetic bacteria apparatus for photoreaction is gone into photosynthetic bacterium air cleaning unit, continue to carry out air cleaning work.Poor efficiency function bacterium liquid then pumps into photosynthetic bacteria apparatus for photoreaction adjustment bacterial concentration and is cultured to the efficient function bacterium liquid standard that reaches.Above cycling.
6. the photosynthetic bacteria apparatus for photoreaction is to adopt high printing opacity soft pipeline, is connected with structures such as flange, ball valve, plastic pumps by hard tube.Support with light steelframe, good natural lighting or artificial daylight can be arranged, circulation and the fully device of light reaction function automatically.High printing opacity pipeline material selection polyester (PET) or PVC plastic material in the base, pipe thickness 0.1-0.5mm, light transmittance 70%-95%, caliber 10-30cm.Its structure sees Figure of description Fig. 1 and description of reference numerals for details.
7. the photosynthetic bacteria air cleaning unit is to adopt high light transmissive material manufacturing, connects and control photosynthetic bacteria liquid with pipeline and ball valve to pass in and out exchange, air-conditioning wind turnover exchange, controls circulation sealing air filter automatically.Wherein high light transmissive material of sealing device material selection alkali resistance such as the contour light-passing plastic of PET.It is some to establish session in the casing, and session and casing periphery are put the incandescent lamp light source.Air-conditioning input contaminated air air port is lower than the bacterium fluid level, and the air port of filtering degraded purification back output pure air is higher than the bacterium fluid level.Box sealing is tight, promotes air input and output with machine power.Its structure sees Figure of description Fig. 2 and description of reference numerals for details.In addition, the sediment of room air pollution filtration treatment can also recycling.
8. apparatus of the present invention connect the central air-conditioning air system plumbing by flange and pipeline, ball valve control, can carry out indoor air purification work.Device can be provided with outdoor as the roof, uses lamp, can also be provided with indoorly, operates with artificial light source.
Beneficial effect
