Description

For the deodorant of the bioactive enzyme cordate houttuynia for the treatment of of urban garbage

Technical field

The present invention relates to a kind of deodorant of the bioactive enzyme cordate houttuynia for treatment of urban garbage.

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 that plant area can be corroded, affects work, the living environment of Sewage Plant and nearby residents, also causes huge to the healthy of people 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, to the foul gas that these regions produce purified treatment is carried out, and 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.It is with compost 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.Generally existing nitrogen is damaged during During High-Temperature Composting 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, the burst size of ammonia is very big in composting process, 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 discharge early stage anaerobic composting process, such 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 Fertilizer and recycle it is outer, wherein more than 90% is transported to refuse landfill and is processed.Rubbish is in the stacking of landfill yard, handling, flat Paving, in compacting process, it is inevitable to produce odor pollution due to the rotten decomposition of wherein organic matter.

At present method conventional both at home and abroad has absorption method, combustion method, energetic ion method and bioanalysis.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 there is 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 The deodorant of the wide bioactive enzyme cordate houttuynia for treatment of urban garbage.

The object of the present invention is achieved like this：

A kind of deodorant of the bioactive enzyme cordate houttuynia for treatment of urban garbage, the biology for treatment of urban garbage The deodorant of organized enzyme cordate houttuynia is made up of microbial bacterial agent, plant extracts, algae extract, bioactive enzyme and water；

The Lactobacillus plantarum of the microbial bacterial agent including 15%-35%, the brewer's yeast of 15%-35%, the Bifidobacterium of 2%-6%, The nitrobacteria of 2%-6% and the streptococcus lactis of 3%-5%；

The plant extracts includes that extract from pine needles, the houttuynia extract of 4%-15% and the peppermint of 3%-8% of 4%-15% carries Take thing；

The algae extract is the brown alga extraction thing of 0.5-2.5%；

Above percentage is mass percent.

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

The present invention is used for the deodorant low cost of the bioactive enzyme cordate houttuynia for the treatment of of urban garbage, and high efficiency adapts to wide, in tool It is very useful in body production.

Specific embodiment
