Description
Technical field
The present invention relates to environmental technology fields, and in particular to the production method of deodoring materials, the deodoring materials of acquisition and its
Purposes and device.
Background technique
Continuous improvement with people to environmental quality requirement, various regions have created more and more environmental protection facilities, such as dirty
Water treatment plant, destructor plant etc..Each processing unit of these facilities can all generate stink.Stench not only seriously affects sewage
The work for the treatment of plant staff also influences the life of nearby residents.
Stench is a kind of perception pollution, it is distributed extensively, is influenced greatly, in addition to the olfactory organ of stimulation people makes one to feel unhappy
Outside, also the digestive system of people, endocrine system, nervous system and spirit are had adverse effect on.China gives off foul smell
Platform relevant regulations, such as " emission standard for odor pollutants " (6814 554-93), " urban wastewater treatment firm pollutant emission
Standard " (GB18918-2002), " household refuse landfill sites control standard " (GB16889-2008), " consumer waste incineration pollution
Control standard " (GB 18485-2014), odor treatment has become a urgent task.
It is different for the pollution sources for generating foul smell, equipment investment and operating cost are combined, foul gas is mainly controlled
Reason technology has: physical method masking method, dilutes diffusion method, combustion method flame combustion method, Production by Catalytic Combustion Process, absorption method, chemical oxidation
Method Ozonation, catalytic oxidation and other oxidizing process, washing method, biofiltration process, biological island, zinc cation method etc.
And plasma method.
Biological deodorization is the important technique measure of modern deodorization technology, it by the characteristic of microorganism, will mainly be deposited
It is absorbed and is converted in the stink substances of odorous gas, be changed into nonirritant gas and harmless substance, such as two
Carbonoxide and water etc., the effect of biological deodorization clearly, while having the characteristics that save resource, environment-friendly high-efficiency.Its by
The attention of sanitation project has obtained huge development.Compared with other materilization freatment methods, advantage is mainly reflected in always bioanalysis
Low energy consumption for body, operation and maintenance cost is few and less the problem of secondary pollution and across medium pollution transfer occurs.These advantages make it
Research and development it is rapid, become the important development direction of odor treatment.
But there is also some disadvantages are anxious to be resolved for biological odor removal method.The treatment effect of biology deodorization technique is also by foul smell
The many factors such as source, flow and temperature influence, and are often difficult to make simultaneously using single deodorization technology complicated and changeable smelly
Gas governance for reaching standard if selection combined type treatment process will make processing system complicated, and increases investment and operating cost.
Filler is the core component of biological deodorizing device, is the carrier of attached growth of microorganisms, substance transmitting, and performance is straight
It connects and affects waste gas purification effect.Ideal filler should have following characteristics: 1. suitable particle size, porosity, specific surface
Product, best carrier should have columned shape；2. higher nutrition supply ability；3. retentiveness is strong；4. buffer capacity is strong,
Biggish pH value is avoided to change；5. mechanical toughness is strong, and has chemical inertness and stability, it is suitable for microorganism carry, growth
Deng.Traditional filler organic material, such as soil, compost, peat, sawdust, bark, corncob, in the process of running Chang Yinyou
The decomposition of machine substance and cause packing layer to collapse, be compacted, is hardened, resistance coefficient increase, to cause biofiltration tower
Odor removal efficient decline；Inorganic material, such as porous ceramic grain, calcining cristobalite, perlite, because being not easy to be compacted with light, firm
The advantages that be also selected frequently as the filler of biofiltration tower, but since these material adsorptivity abilities are small, poor water retention property and nothing
Method provides nutrition etc. for microbial growth, generally require during processing the nutrition such as addition carbon source and phosphorous first rope at
Point.
Domestic waste increases sharply, land occupation, pollutes the situation of environment and the influence to health of people is also got over
Add obvious.Msw water content and biodegradable high organic content, keep garbage disposal more and more difficult, and China will realize city
The industrialization of city's house refuse, recycling, minimizing and innoxious, must just break through these problems from technical matters.
