Description

Solid life refuse microbial deodorant

Technical field

The present invention relates to a kind of solid life refuse microbial deodorant.

Background technology

Along with improving constantly of social progress, economic development, the knowledge enhancing of people's environment and quality of life, foul gas controls The most increasingly paid attention to process problem.Gas is mainly some sulfur-containing compound and nitrogen-containing compounds etc., such as hydrogen sulfide, first sulfur Alcohol, thioether, ammonia etc., have strong impulse abnormal flavour, very harmful to human body, can be through differences such as respiratory tract, eye, skins Approach enters human body, makes that people is dizzy, feel bad, stay wherein for a long time, very big to the nervous system damage of human body.Foul gas is not only The equipment of plant area can be corroded, affect Sewage Plant and the work of nearby residents, living environment, also people healthy be caused huge Harm, cause Nausea and vomiting it could even be possible to cause distortion, canceration etc. to act on.Therefore, it is necessary to take practicable doing Method, the foul gas producing these regions carries out purified treatment, improves the environmental quality of its space and periphery.

Mainly there are sewage treatment plant, refuse landfill, also compost factory etc. in the source produced at 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.Generally there is nitrogen during During High-Temperature Composting to damage The phenomenon lost, general nitrogen loss rate can reach 30% 50%, in sludge composting even as high as 68%.Ammonia is at 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 the most secondary odorant. Although sulfur-containing foul compound such as hydrogen sulfide, methanthiol, methyl sulfide and Methyl disulfide (the generation amount of DMDQ is less than NH3, but it Threshold value the lowest, thus to total stench contribution the biggest.VOCs is a series of vapour pressures under 20 ° of C > volatilization of 0. 01 Ua Property organic compound, Eitzer studies discovery, and most of VOCs discharge anaerobic composting process early stage, as at dump plaftorm, powder Broken machine and initial activation compost region.China's domestic waste year amount of clearing is about 1.4 hundred million tons, except small part burning, heap Fertile and outside recycling, wherein more than 90% it is transported to refuse landfill and processes.Rubbish landfill yard stacking, load and unload, flat Paving, in compacting process, due to the most organic rotten decomposition, inevitable must produce odor pollution.

The most conventional method has absorption method, combustion method, energetic ion method and bioanalysis.Absorption method includes acid The washing of alkali liquid medicine and activated carbon adsorption, the former needs to consume a large amount of chemical agent, the latter Ze Yi blocking, changes frequently, safeguard 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 produces directly discharges, it is possible to can endanger Environmental security, and its ion produced 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 relatively low, the former needs the debugging time, and the latter then needs 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, adapt to wide method.

Summary of the invention

It is an object of the invention to overcome above-mentioned deficiency, it is provided that a kind of cheap, efficiency is high and subject range very Wide solid life refuse microbial deodorant.

The object of the present invention is achieved like this:

A kind of solid life refuse microbial deodorant, described solid life refuse microbial deodorant is by microbial bacteria Agent, plant extract, algae extract, bioactive enzyme and water composition；

Described microbial bacterial agent includes the Lactobacillus plantarum of 15%-35%, the beer yeast of 15%-35%, and the Composite Photosynthetic of 2%-6% is thin Bacterium, the improvement denitrifying bacterium of 2%-6% and the actinomycetes of 3%-5%；

Described plant extract includes that the Borneolum Syntheticum of the Rhizoma Zingiberis Recens extract of 5%-15%, the Herba Houttuyniae extract of 4%-15% and 3%-8% carries Take thing；

Described algae extract is the spirulina extract of 0.5-2.5%；

Above percentage ratio is mass percent.

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

Solid life refuse microbial deodorant low cost of the present invention, high efficiency, adapt to wide, the most real in concrete production With.

Detailed description of the invention

The formula of solid life refuse microbial deodorant of the present invention includes specific as follows:

Described solid life refuse microbial deodorant is by microbial bacterial agent, plant extract, algae extract, biological activity Enzyme and water composition；

Described microbial bacterial agent includes the Lactobacillus plantarum of 15%-35%, the beer yeast of 15%-35%, and the Composite Photosynthetic of 2%-6% is thin Bacterium, the improvement denitrifying bacterium of 2%-6% and the actinomycetes of 3%-5%；

Described plant extract includes that the Borneolum Syntheticum of the Rhizoma Zingiberis Recens extract of 5%-15%, the Herba Houttuyniae extract of 4%-15% and 3%-8% carries Take thing；

Described algae extract is the spirulina extract of 0.5-2.5%；

Above percentage ratio is mass percent；

The preparation method of solid life refuse microbial deodorant comprises the following steps:

(1) expanding propagation is cultivated

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

(2) ferment in second time

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

(3) mixing

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

Solid life refuse microbial deodorant living bacteria count of the present invention is high, and deodorization rate reaches more than 96%, and effect shows Write.Tested in Guangdong Province with solid life refuse microbial deodorant of the present invention, be experimental field 1,000 squares for area The house refuse of rice, through 15 days fermentative deodorizings, stink reduced 85%；After 25 days, reach odorless；After testing, sludge table Face living bacteria count 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 having Effect viable count is ten thousand/g of 500-800.
