Description

Garbage disposal microbial deodorant is fixed in city

Technical field

The present invention relates to garbage disposal microbial deodorant is fixed in a kind of city.

Background technology

As social progress, economic development, people's environment know enhancing and the continuous improvement of quality of life, foul gass control Increasingly paid attention to process problem.Gas is mainly some sulfur-containing compounds and nitrogen-containing compound etc., such as hydrogen sulfide, first sulfur Alcohol, thioether, ammonia etc., with strong impulse abnormal flavour, to the very harmful of human body, can the difference such as Jing respiratory tracts, eye, skin Approach enters human body, makes one dizzy, feels bad, stays for a long time wherein, very big to the nervous system damage of human body.Foul gass are not only The equipment of plant area can be corroded, work, the living environment of Sewage Plant and nearby residents is affected, huge is caused to the healthy of people also Harm, cause Nausea and vomiting, it could even be possible to causing distortion, canceration etc. to act on.Therefore, it is necessary to take practicable doing The foul gass that these regions produce are carried out purified treatment, improve the environmental quality of its space and periphery by method.

Mainly there are sewage treatment plant, also refuse landfill, compost factory etc. in the source produced in foul smell.With compost it is Example, wherein the composition of foul smell mainly has sulfur-containing compound, nitrogen-containing compound and volatile organic contaminant（VOCs).Nitrogenous stench Material mainly has ammonia, amine, indole and scatol, and wherein ammonia is of greatest concern.During During High-Temperature Composting, generally existing nitrogen is damaged The phenomenon of mistake, general nitrogen loss rate can reach 30% 50%, even as high as 68% in sludge composting.Ammonia is in protein and ammonia Can produce in the aerobic and anaerobic degradation of base acid, in composting process, the burst size of ammonia is very big, ammonia during sludge composting Concentration may be up to 1000 mg/kg, but the foul smell threshold value of ammonia is of a relatively high, it is generally recognized that it is relatively secondary odorant. Although sulfur-containing foul compound such as hydrogen sulfide, methanthiol, methyl sulfide and Methyl disulfide（The yield of DMDQ is less than NH3, but it Threshold value it is very low, thus to total stench contribute it is very big.VOCs is a series of in 20 °C of lower vapour pressures>The volatilization of 0. 01 Ua Property organic compound, Eitzer research find, most of VOCs are discharged early stage anaerobic composting process, such as in dump plaftorm, powder Broken machine and initial activation compost region.About 1.4 hundred million tons of China's domestic waste year amount of clearing, except small part burning, heap Fertilizer and recycling are outer, and wherein more than 90% is transported to refuse landfill is processed.Rubbish is in the stacking of landfill yard, handling, flat Paving, in compacting process, it is due to the rotten decomposition of wherein Organic substance, inevitable to produce odor pollution.

Method conventional both at home and abroad has absorption method, combustion method, energetic ion method and bioanalysises at present.Absorption method includes acid Alkali liquid medicine is washed and activated carbon adsorption, and the former needs to consume a large amount of chemical agents, and the latter Ze Yi blockings are changed frequent, safeguarded It is costly；Combustion method is suitable for the organic exhaust gas of high concentration, high heating value, seldom applies in general deodorization engineering；High energy The ozone that ion method is produced directly is discharged, it is possible to can endanger Environmental security, and its ion for producing has strong oxidation, right Equipment has corrosiveness, and also has certain injury to the person；Bioanalysises include biological filtering tower combined working, also biological deodorant, one As cost it is relatively low, the former needs debug time, the latter then to need more complicated condition of culture, just has efficient deodorizing effect.Institute With for the process of foul gass, it is necessary to find a low cost, high efficiency adapts to wide method.

The content of the invention

It is an object of the invention to overcome above-mentioned deficiency, there is provided a kind of cheap, efficiency high and subject range is very Garbage disposal microbial deodorant is fixed in wide city.

The object of the present invention is achieved like this：

Garbage disposal microbial deodorant is fixed in a kind of city, and garbage disposal microbial deodorant is fixed by micro- in the city Bacteria agent, plant extract, algae extract, bioactive enzyme and water composition；

The microbial bacterial agent includes the Lactobacillus plantarum of 15%-35%, the beer yeast of 15%-35%, the bacillus bifiduss of 2%-6%, The improvement denitrifying bacterium and the streptococcus acidi lactici of 3%-5% of 2%-6%；

The plant extract includes the Rhizoma Zingiberis Recens extract of the Flos Chrysanthemi of 5%-12%, the Herba Houttuyniae extract of 4%-15% and 3%-8%；

Spirulina extract of the algae extract for 0.5-2.5%；

Above percentage ratio is mass percent.

Compared with prior art, the invention has the beneficial effects as follows：

Garbage disposal microbial deodorant low cost is fixed in city of the present invention, and high efficiency adapts to wide, in concrete production very It is practical.

Specific embodiment

The formula of fixation garbage disposal microbial deodorant in city of the present invention includes specific as follows：

Garbage disposal microbial deodorant is fixed by microbial bacterial agent, plant extract, algae extract, biology in the city Organized enzyme and water composition；

The microbial bacterial agent includes the Lactobacillus plantarum of 15%-35%, the beer yeast of 15%-35%, the bacillus bifiduss of 2%-6%, The improvement denitrifying bacterium and the streptococcus acidi lactici of 3%-5% of 2%-6%；

The plant extract includes the Rhizoma Zingiberis Recens extract of the Flos Chrysanthemi of 5%-12%, the Herba Houttuyniae extract of 4%-15% and 3%-8%；

Spirulina extract of the algae extract for 0.5-2.5%；

Above percentage ratio is mass percent；

City is fixed the preparation method of garbage disposal microbial deodorant and is comprised the following steps：

（1）Expanding propagation culture

Strain in microbial bacterial agent is according to type inoculated in multiple fluid mediums respectively, under the conditions of 25 DEG C -35 DEG C Culture；The viable count of strain is checked respectively for after 24h, then according to ratio is mixed to get microbial bacterial agent；

（2）Ferment in second time

Microbial bacterial agent is seeded in molasses culture medium, under the conditions of 25 DEG C -35 DEG C, then pH value is adjusted by sealing culture 2 weeks Just odor control agent composition is obtained to 3-4；Molasses culture medium includes molasses and water, and the microbial bacterial agent accounts for 3%-5%, molasses accounting 10%-15%, is wherein water；

（3）Mixing

The water of 15-20 part plant extracts, 5-10 part algae extracts, 1-3 parts bioactive enzyme and 900-950 parts is mixed To extract mixtures, by above-mentioned steps（2）The odor control agent composition that obtains and the extract mixtures are according to 1.5:1 mass ratio It is mixed to get biological deodorant.

It is high that garbage disposal microbial deodorant living bacteria count is fixed in city of the present invention, deodorizing rate up to more than 96%, effect Significantly.Garbage disposal is fixed with city of the present invention to be tested in Guangdong Province with microbial deodorant, experimental field for area be 1 Thousand square metres of house refuse, through 15 days fermentative deodorizings, stink reduced 85%；After 25 days, odorless is reached；After testing, it is dirty Ni Dui surfaces living bacteria count about 100,000,000/g, the living bacteria count about 30,000,000/g of 30 centimetres of depths, less than 50 centimetres Deep living bacteria count is ten thousand/g of 500-800.
