Description

Garbage-cleaning complex microorganism deodorant

Technical field

The present invention relates to a kind of garbage-cleaning complex microorganism deodorant.

Background technology

With the continuous improvement of social progress, economic development, the knowledge enhancing of people's environment and quality of life, foul gas controls 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., have strong impulse peculiar smell, very harmful to human body, can be through differences such as respiratory tract, eye, skins Approach enters human body, makes one dizzy, feels bad, stays wherein for a long time, very big to the nervous system damage of human body.Foul gas is not only Can corrode the equipment of plant area, the work of impact Sewage Plant and nearby residents, living environment, also to people healthy cause huge 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, the foul gas that these regions are produced 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 producing 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 damages The phenomenon lost, 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 very low, thus to total stench contribute 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 finds, most of VOCs discharges early stage anaerobic composting process, as in 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 recycling is 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, due to the rotten decomposition of wherein organic matter, inevitable must produce odor pollution.

The method commonly used both at home and abroad at present has absorption method, combustion method, energetic ion method and bioanalysis.Absorption method includes acid The washing of alkali liquid medicine and charcoal absorption, the former needs to consume a large amount of chemical agents, and the latter Ze Yi blocks, and changes frequently, safeguards 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 produces directly discharges it is possible to Environmental security can be endangered, and its ion 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, and one As cost relatively low, the former needs debug time, and the latter then needs more complicated condition of culture, just has efficient deodorizing effect.Institute So that the process for foul gas, it is necessary to one low cost of searching, high efficiency, adapts to wide method.

Content of the invention

It is an object of the invention to overcoming above-mentioned deficiency, a kind of cheap, efficiency high being provided and accommodation is very Wide garbage-cleaning complex microorganism deodorant.

The object of the present invention is achieved like this：

A kind of garbage-cleaning complex microorganism deodorant, described garbage-cleaning complex microorganism deodorant is by microbial bacterial agent, plant Thing extract, algae extract, bacteria activator and water composition；

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

The garden burnet that described plant extracts includes the Ginger P.E of 6%-12%, the houttuynia extract of 4%-15% and 3%-8% carries Take thing；

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

Above percentage is mass percent.

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

Garbage-cleaning complex microorganism deodorant low cost of the present invention, high efficiency, adapt to wide, very useful in concrete production.

Specific embodiment

The formula of garbage-cleaning complex microorganism deodorant of the present invention includes specific as follows：
