Description

A kind of ecological technique is purification of air regenerating unit and the method for core
Technical field
The present invention relates to the device and method of a kind of purification of air regeneration, specifically a kind of take ecological technique as multi-stage treatment units and the method for air being carried out to purifying regeneration of core.
Background technology
Air is one of basic guarantee condition of human survival, and the height of air quality has a strong impact on the quality of working life of people.Along with the high speed development of industrialization and urbanization, China's major part city is just suffering the pollution of serious sulfur dioxide, nitrogen oxide and coal smoke-photochemistry haze at present.For indoor environment, problem is also very serious, and especially with the VOC organic pollution accumulation that benzene, formaldehyde are representative, concentration is up to outdoor more than ten times.The Cure of Sick Building Syndrome (SickBuilding Syndrome, SBS) that new wind is not enough, air quality is poor etc. causes has become the key factor of the healthy and operating efficiency of impact.In the urgent need to developing advanced practical purification of air regenerating unit and method.
From the composition of air, nitrogen and oxygen are topmost compositions, oxygen is the nutrient that human body erythrocyte normally runs, lower than 18% in air, hypoxic conditions will be caused, other compositions, such as gas concentration lwevel is generally in hundreds of ppm (1,000,000/), concentration rising can have a strong impact on the physiological status of people, and benzene homologues, formaldehyde etc. are very big to human health damage, and long-term exposure can increase risk of cancer.
For these problems, the treatment technology studying application at present comprises: absorption process, absorption method, bioanalysis, low-temperature plasma method, photocatalytic method etc.Be that the physical-chemical process of representative develops comparative maturity at present with absorption method, pollutant removal has played important function.Active carbon adsorption is one of most popular method, and active carbon has the unique texture of flourishing gap structure, huge specific area and special surface functional group, makes it have good adsorptivity, can multiple pollutant effectively in Adsorption air.Such as ZL 200910017520.2, ZL200910091748.6, the disclosure of the invention such as ZL201310351413.X can the effective sorbing material preparation and application of formaldehyde and other harmful substance in absorbed air, it take photocatalysis as the harmful substance removal device of core and the air cleaning unit of this removal device of use that ZL 201110072528.6 discloses a kind of, and ZL 201120184086.X discloses a kind of apparatus for physical Chemical treating be made up of dust filter unit, Electrostatic adsorption unit, charcoal absorption+photocatalyst filter unit, UV lamp tube unit.But these devices and technology, cannot solve the decomposition of adsorbing saturated after stain thing, oxygen concentration deficiency waits air regenesis problem, and oxidation reaction class technology easily generates the noxious products such as ozone, sour aldehyde causes secondary pollution.
Bioanalysis is by utilizing the metabolism of the nature such as microorganism, the plant producer, pollutant, carbon dioxide etc. are changed into oxygen, it is a kind of technology of green ecological, there is wide application potential, especially can form effective working in coordination with physico-chemical process to strengthen, reach the object of purification of air regeneration.Propose a kind of plant-supported biological filtration purifier in Chinese patent ZL 200520067034.9, this utility model sucks air, through water, filtrate and potted plant synergy, and circularly purifying room air.In this utility model, first air is blasted tank by air blast and washs, and then is entered the flowerpot being filled with the filtrate such as active carbon, zeolite by gas distribution pipe, and plant cultivating, among flowerpot, is that one is significantly attempted; A kind of air purification method and system is disclosed in Chinese patent CN 103386245 A, natural plants and physico-chemical purification combine with technique get up by this invention, utilize the soil of planting as filter, air is made to carry out pretreatment through soil, pretreated air carries out advanced treating through air-purifying module again, discharges cleaned air finally by air outlet.But can see from claims, this invention is due to without plant and bacterial classification preferred disposition, a plant number few (individual plant), inanimate object control measure (temperature and humidity conditions, nutriment supply), estimate that the biological agent in this patented technology is limited, main treatment effect is still by the air physical chemical cleaning method module described in invention, the technology such as such as nano photo catalyzed oxidation, anion technology, silver ion technology complete, and effectively can not solve aforesaid materialization technology Problems existing.
