Abstract
The invention provides a method for filtration deodorization by utilizing biological soil. The method is characterized in that obnoxious gas is collected and humidified and then is evenly distributed onto the bottom of the biological soil by a gas distributing device, and purification on obnoxious gas is realized by absorption of the biological soil and micro organism in the biological soil; and the micro organism in the biological soil is mainly pseudomonas and thiophilic bacillus. The invention also provides a filtration deodorization device utilizing the biological soil. The invention adopts biological filtration method to remove odour, hydrogen sulphide and organic gas in odour are absorbed on the surface of particle of soil filtering layer and on the surface of micro organism cell in the filtering layer, odour is absorbed by micro organism, organic gas participates micro organism metabolism and is oxidated into carbon dioxide and water; odour and soil provide oxygen, moisture and mineral nutrient components for metabolism of micro organism, deodorization effect is good, and no secondary pollution is produced.
Description
Technical field
The invention belongs to environmental protection, exhaust-gas treatment field, be specifically related to a kind of method and device that utilizes the biological soil filtration deodorization.
Background technology
The enhancing of the environmental consciousness of Along with people's, also increasingly high to the requirement of environmental quality, also responsive more to the pollution that stench brings.Stench is meant that gaseous material passes through a kind of psychological unplessantness displeasure or the detest sense of people's sense of smell generation, and odor pollution is a kind of sensation public hazards, has become one of seven overall situation public hazards in the world.Urban wastewater treatment firm has stronger foul smell to produce in running, has a strong impact on surrounding environment, and the health of staff and surrounding resident has been caused harm.
Existing deodorization technology and treating apparatus are generally: the biofilter utilizes organic media filtration deodorizing, the deodorizing of ion generator ion method, plant extraction liquid deodorizing.Organic media filtration deodorizing must be changed filtrate in per 2～5 years again, along with the lengthening of running time, and the hardening of filtrate, resistance constantly increases, and the gas short circuit can take place in system, influences treatment effect; Odor removal is by cloth gas-bearing formation, pond, ph appearance, pickling or alkaline cleaner, be made up of equipment such as machine filter body, biological nutrient liquid, water circulating pumps, complex structure, and operating cost is high; Except the equipment and the installation cost of disposable input, every 2-5 must change filtrate and carry out culture of strains, and the installation of repetition and replacing filtrate have increased operating cost, and the filtrate under changing need be handled, and causes secondary pollution easily; Whole device is a container-type or tower, can not afforest, and influences the integrated greening of entire sewage treatment plant.Ion deodorization can only be used for less tolerance (like pumping plant), and is inapplicable for Sewage Plant atm number (like mud district, aeration tank etc.); Gas after the processing need be concentrated discharging (as adopting exhaust chimney), except the required electricity consumption of fan operation, also will utilize electric energy to produce ion, and operating cost is high, energetic ion generator rapid wear, and the life-span is low.The plant extraction liquid deodorizing; The composite liquid that forms of the juice that from plant, extracts; Be adsorbed on after the atomizing on the odor causing substance, the generation displacement waits chemical reaction need continuously spray extract and generally is applied in public arenas change air components such as hotel, hotel, market, office building, produces S
2-, SO
4 2-, there is potential hazard in human body.
Summary of the invention
The object of the present invention is to provide a kind of process equipment simple, the method for utilizing the biological soil filtration deodorization that operating cost is low.
Another object of the present invention is to provide this device that utilizes the biological soil filtration deodorization.
The objective of the invention is to realize: a kind of method of utilizing the biological soil filtration deodorization through following technical scheme; It is characterized in that: after foul gas is collected; Humidification; Be distributed to the bottom of biological soil again through distribution device equably, realize purification foul gas through the microorganism in absorption, absorption and the biological soil of biological soil; Microorganism in the said biological soil mainly is pseudomonad (Pseudomonas Thiobacillus) and has a liking for Thiobacillus (Microbialenzyme) etc. that according to detecting, the microorganism of biological soil surface coverage is up to 1,000,000,000/gram.
The reaction equation of microbial degradation foul smell can be reduced to: microorganism+organic foul smell molecule → CO
2+ H
2The O+ cell mass
Microbial inoculant method in the soil is: at the disposable spray concentration of biological soil initial start stage is 1～10% microorganism stoste, in order to activate the microorganism in the soil; Periodically sprinkle microorganism stoste is as required replenished the microorganism in the soil then.Microorganism stoste is from soil, to extract, and Main Ingredients and Appearance is pseudomonad (Pseudomonas Thiobacillus), have a liking for Thiobacillus (Microbial enzyme).Disposable sprinkling when starting usually, the later stage need not to spray.Only if odor removal is out of service more than one month, in the time of need restarting, need to spray once more.
In order to make good filtration effect, said biological soil be porosity 20%～40%, pore diameter is 0.01～0.10 millimeter the sandy soil with better filterability.
For good deodorization effect, on said biological soil, plant and be implanted with vegetation, be generally lawn or leguminous forage.
Another object of the present invention is achieved in that a kind of device that utilizes the biological soil filtration deodorization; It is characterized in that: mainly comprise blower unit, damping device, distribution device and biological soil device four parts, said biological soil device mainly is made up of housing and the cobblestone layer, the biological soil layer that are arranged in the housing; Said cobblestone layer is arranged on the bottom in the said housing, is biological soil horizon on it; Microorganism in the said biological soil layer mainly is pseudomonad and has a liking for Thiobacillus etc.;
Said blower unit is collected pending foul gas, behind the damping device humidification, blasts distribution device; Said distribution device is provided with in the said cobblestone layer.
In order to make good filtration effect, the biological soil in the said biological soil layer be porosity 20%～40%, pore diameter is 0.01～0.10 millimeter the sandy soil with filterability.
In order to make good deodorization effect, above said biological soil layer, plant and be implanted with vegetation, be generally lawn or leguminous forage.
Above said biological soil device, also be provided with water injector, except water spray in soil, also can regularly contain the microorganism soup, not only keep soil moisture but also effectively replenish odor removal desired microorganisms amount to the biological soil sprinkling.
Biological soil deodorizing principle of the present invention is: the foul smell of collecting from each structures is at first sucked by blower unit; Blower unit adopts air blast usually; Foul smell gets into distribution device after keeping the skin wet through damping device, generally adopts the perforated pipe gas distribution, and foul smell is at leisure upwards through the biological soil filtering layer; Hydrogen sulfide in the foul smell and organic gas are adsorbed on the microbial cell surface in soil filtering layer particle surface and the filtering layer; Be oxidized to carbon dioxide and water through the microbial metabolism effect, finally leave from the biological soil filtering laminar surface, thereby foul smell obtains handling with the form of diffusion air-flow.Foul smell and soil provide oxygen, moisture and mineral nutrition composition for microorganism metabolism.
The present invention has good effect of removing to foul gas, and the embodiment of the present invention method is to the removal effect test result such as the table 1 of foul gas:
