Abstract
The invention discloses a biological deodorant. The biological deodorant comprises, by weight, 10-15 parts of photosynthetic bacteria, 30-50 parts of lactic acid bacteria, 20-30 parts of microzyme, 10-20 parts of nitrobacteria and 10-15 parts of actinomyces. The invention also discloses a preparation method of the above biological agent. The biological deodorant can absorb and convert ammonia gas and other stink gases, has fast effect and strong adaptability. Self fermentation acid production of the original biological agent makes the pH value be reduced to 3-4, so substances generating stink are absorbed and decomposed, thereby the deodorization effect is efficient and stable; and generation of stink is fundamentally inhibited to a certain degree with colonization of microbes in the biological agent in a stink source.
Description
Technical field
The invention belongs to microorganism field, be specifically related to a kind of microbial deodorant and preparation method thereof.
Background technology
Along with social progress, economic development, people's environmental consciousness strengthen and the improving constantly of quality of life, foul gas controls more and more to be paid attention to process problem.Gas is some sulfur-containing compound and nitrogen-containing compounds etc. mainly, as hydrogen sulfide, methanthiol, thioether, ammonia, VOC etc., there is strong impulse abnormal flavour, very harmful to human body, human body can be entered through different approaches such as respiratory tract, eye, skins, make people's giddy, feel bad, stay wherein for a long time, very big to the nervous system damage of human body.Foul gas not only can corrode the equipment of plant area, affects the work of Sewage Plant and nearby residents, living environment, also causes huge harm to the healthy of people, causes nausea, vomits, even likely causes the effects such as distortion, canceration.Wherein particularly evident with the toxicity of hydrogen sulfide, people sucks 70 ~ 150mg/m3/1 ~ 2 hour, occurs respiratory tract and Eye irritation symptom, inhales olfactory fatigue after 2 ~ 5 minutes, no longer smells foul smell.Suck 300mg/m3/1 hour, go out to lose face acute irritation symptoms for 6 ~ 8 minutes, and slightly Long contact time causes pulmonary edema.Suck 760mg/m3/15 ~ 60 minute, pulmonary edema, bronchitis and pneumonia, headache, giddy, instability of gait, Nausea and vomiting occur.Suck the 1000mg/m3/ several seconds, occur acute poisoning very soon, respiratory paralysis after accelerated breathing and dead.Therefore, must practical ways be taked, purified treatment be carried out to the foul gas that these regions produce, improves the environmental quality of its space and periphery.
The source produced at foul smell mainly contains sewage treatment plant, refuse landfill, also has compost factory etc.For compost, wherein the composition of foul smell mainly contains sulfur-containing compound, nitrogen-containing compound and volatile organic contaminant (VOCs).Nitrogenous odorant mainly contains ammonia, amine, indole and scatol, and wherein ammonia is of greatest concern.The phenomenon of ubiquity nitrogen loss in During High-Temperature Composting process, general nitrogen loss rate can reach 30%-50%, even up to 68% in sludge composting.Ammonia can produce in protein and amino acid whose aerobic and anaerobic degradation, in composting process, the burst size of ammonia is very large, in sludge composting process, the concentration of ammonia can up to 1000mg/kg, but the foul smell threshold value of ammonia is relatively high, it has been generally acknowledged that it is relatively secondary odorant.Although the generation of sulfur-containing foul compound as hydrogen sulfide, methanthiol, methyl sulfide and Methyl disulfide (DMDS) is less than NH3, their threshold value is very low, thus very large to total stench contribution.VOCs is the VOC of a series of vapour pressure >0.01kPa at 20 DEG C, and Eitzer studies discovery, most of VOCs in the early stage release of anaerobic composting process, as in dump plaftorm, pulverizer and initial activation compost region.China's domestic waste year amount of clearing is about 1.4 hundred million tons, except small part is burned, except compost and recycling, wherein more than 90% is transported to refuse landfill and processes.Rubbish, in the stacking of landfill yard, handling, tiling, compacting process, due to wherein organic rotten decomposition, unavoidably must produce odor pollution.
Country has formulated " emission standard for odor pollutants " (GB14554-1993) for 1993, but due to technical limitation, only in part sector application, especially closely bound up with common people Municipal Industry not real implementing is promoted." urban wastewater treatment firm pollutant emission standard " (GB18918-2002) of December in 2002 issue on the 4th, provide clear and definite index request for material factory circle discharge maximum permissible concentrations such as NH3, H2S, odor concentration, methane.The sewage treatment plant of (comprise change, extend) for building before Abgasvorschriften on June 30th, 2003, the time of implementation criteria is on January 1st, 2006;
Play the urban wastewater treatment firm of newly-built (comprise change, extend) on July 1st, 2003, start to perform from this standard is implemented.
Sludge composting (biological dewatered) does not formulate special standard though project is existing, should include above-mentioned standard criterion category in yet.
Method conventional both at home and abroad at present has absorption method, combustion method, energetic ion method and bioanalysis.Absorption method comprises acid _ _ alkali liquid medicine washing and activated carbon adsorption, and the former needs to consume a large amount of chemical agent, and latter easily blocks, and change frequent, maintenance cost is higher; Combustion method is suitable for the organic exhaust gas of high concentration, high heating value, and general deodorization engineering is seldom applied; The ozone that energetic ion method produces directly discharges, and likely can endanger Environmental security, and its ion produced has strong oxidation, has corrosiveness, and also have certain injury to the person to equipment; Bioanalysis comprises biological filtering tower combined working, and also have biological deodorant, general cost is lower, and the former needs debug time, and latter needs more complicated condition of culture, just has efficient deodorizing effect.So, for the process of foul gas, a cost must be found low, efficiently high, the method for wide adaptability.
