Description

House refuse high efficiency composition deodorant

Technical field

The present invention relates to a kind of house refuse high efficiency composition deodorant.

Background technology

As social progress, economic development, people's environment know enhancing and the continuous improvement of quality of life, foul gas control Increasingly paid attention to process problem.Gas is mainly some sulfur-containing compounds and nitrogen-containing compound etc., such as hydrogen sulfide, first sulphur Alcohol, thioether, ammonia etc., with strong impulse peculiar smell, 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 gas is 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 Method, carries out purified treatment to the foul gas that these regions produce, improves the environmental quality of its space and periphery.

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, indoles 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, methyl mercaptan, methyl sulfide and DMDS（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 matter, inevitable to produce odor pollution.

Method conventional both at home and abroad has absorption method, combustion method, energetic ion method and bioanalysis at present.Absorption method includes acid Alkali liquid medicine is washed and charcoal absorption, 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 deodorant 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；Bioanalysis includes 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 gas, 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 accommodation is very Wide house refuse high efficiency composition deodorant.

The object of the present invention is achieved like this：

A kind of house refuse high efficiency composition deodorant, the house refuse high efficiency composition deodorant are carried by microbial bacterial agent, plant Take thing, algae extract, bacteria activator and water composition；

The microbial bacterial agent includes the Lactobacillus plantarum of 15%-35%, and the brewer's yeast of 15%-35%, the Composite Photosynthetic of 2%-6% are thin The azotobacter chroococcum of bacterium, the nitrobacteria of 2%-6% and 3%-5%；

The plant extracts includes that borneol extract, the houttuynia extract of 4%-15% and the peppermint of 3%-8% of 5%-10% carries Take thing；

Brown alga extraction thing of the algae extract for 0.5-2.5%；

Above percentage is mass percent.

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

House refuse high efficiency composition deodorant low cost of the present invention, high efficiency adapt to wide, very useful in concrete production.

Specific embodiment

The formula of house refuse high efficiency composition deodorant of the present invention includes specific as follows：

The house refuse high efficiency composition deodorant by microbial bacterial agent, plant extracts, algae extract, bacteria activator and Water is constituted；

The microbial bacterial agent includes the Lactobacillus plantarum of 15%-35%, and the brewer's yeast of 15%-35%, the Composite Photosynthetic of 2%-6% are thin The azotobacter chroococcum of bacterium, the nitrobacteria of 2%-6% and 3%-5%；

The plant extracts includes that borneol extract, the houttuynia extract of 4%-15% and the peppermint of 3%-8% of 5%-10% carries Take thing；

Brown alga extraction thing of the algae extract for 0.5-2.5%；

Above percentage is mass percent；

The preparation method of house refuse high efficiency composition deodorant is comprised the following steps：

（1）Expand numerous culture

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

（2）Secondary fermentation

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 bacteria activator 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.

House refuse high efficiency composition deodorant living bacteria count of the present invention is high, deodorizing rate up to more than 96%, effect is significant.With House refuse high efficiency composition deodorant of the present invention is tested in Guangdong Province, is experimental field life that area is 1,000 square metres Rubbish, through 15 days fermentative deodorizings, stink reduced 85%；After 25 days, odorless is reached；After testing, sludge surface is effectively lived Bacterium number is about 100,000,000/g, and the living bacteria count of 30 centimetres of depths is about 30,000,000/g, less than 50 centimetres deep living bacteria counts For ten thousand/g of 500-800.
