Description
Technical field
The invention belongs to and adopt the chemical-biological easy rancid organic waste of method process and agricultural fertilizer field, be specifically related to perishable oxidation operation agent and treatment system and the preparation method containing humic acid fertilizer.
Background technology
Humatite source humic acid (humic acid from organic minerals) is the humic acid being comprised the processing preparations such as weathered coal, brown coal, peat by mineral raw material, is called for short coal humic acid or humic acid in peat
Non-mineral source biomass humic acid (humic acid from nom-mineral biomass) is the byproduct produced with agriculture and forestry, industrial organic detritus, waste liquid etc. are raw material, adopt humic acid prepared by biotechnology and employed physico-chemical techniques.Be called for short biological humic or biochemical humic acid.
The bioremediation that city domestic sewage treatment plant of China mainly adopts is activated sludge process, and in activated sludge process processing procedure, a part of mud recycles as contact, is called returned sludge (return sludge); The needs remained go process be called excess sludge (excrss sludge).In excess sludge, solids is based on organic matter, comprise fat, protein and carbohydrate etc., account for 55% ~ 70% of solid sludges content, the solid matter of excess sludge has 5 parts to form, respectively: activated micropopulation, the microorganism autoxidation residue being difficult to degrade, difficult inert organic matter, inorganic matter, the organic matter that is easily degraded decomposed by Institute of Micro-biology.Mainly containing harmful substances in mud is heavy metal, pathogen microorganism and organic poison.Wherein the confined main reason of the extensive Land_use change of mud is exactly heavy metal.Excess sludge water content 97% ~ 99%, through concentration, removes the interstitial water in mud, moisture percentage in sewage sludge can be made to be reduced to 94% ~ 96%, and the volume-diminished of mud, to original about 1/4, is still working fluid, easy corruption is smelly, is unfavorable for transport and process.Current most domestic Sewage Plant adopts organic polymer and centrifuge or filter press to dewater further to mud, to moisture content about 80%.Dewatered sludge, volume-diminished is to 1/4 of thickened sludge, and volume greatly reduces, and the content of the utilized material of mud increases, and decreases expense and the amount of landfill of outward transport.But owing to disposing indefinite, the most of dewatered sludge of target without stabilization processes, because containing heavy metal, easily biodegradable organics, odorant, pathogen etc., make pollutant transfer to land from sewage, cause pollutant to spread further.Still there is easy corruption, smelly problem in dewatered sludge, the environmental malodors event that various places are caused due to mud takes place frequently, mud is arbitrarily stacked and the pollution that causes day by day highlights with pollution problem again, and cause the concern of society, the environmental benefit building up the large quantities of sewage treatment facilities put into operation is had a greatly reduced quality, carries out the inevitable choice that sludge deep process is Treatment of Sludge development.
The dewatered sludge of current China Sewage Plant, landfill accounts for 60% ~ 65%, sludge aerobic fermentation+agriculturally account for 10% ~ 15%, mud nature mummification comprehensive utilization accounts for 4% ~ 6%, sludge incineration accounts for 2% ~ 3%, mud air storage and outward transport account for 15% ~ 20%.In fact, the mud of landfill, air storage and outward transport belongs to random disposal in China's overwhelming majority, and the ratio really realizing safe disposal is no more than 20%.
A research according to Nanjing soil research institute of the Chinese Academy of Sciences finds, after on the soil of its test, continuous administration mud reaches 10 years, Cadmium in Soil, zinc, copper content are all very high, and the paddy rice of plantation, vegetables are subject to serious pollution.The farmland of applying sludge, although the soil organism obviously increases, soil aciditiy is substantially unchanged, and the mercury in soil, cadmium pollution seriously, can cause the pollution of wheat, corn.
Sludge stabilization technology mainly contains the fermentation of high-temperature aerobic wet type, anaerobic fermentation and aerobic compost etc., wherein high-temperature aerobic wet type fermentation, anaerobic fermentation, core technology equipment mainly relies on developed countries, and investment is large, account for 1/3 ~ 1/2 of Sewage Plant gross investment, be difficult to promote in China; Aerobic compost investment is little, and technology and equipment also all realizes production domesticization, but due to compost floor space large, the biofermentation deodorizing cycle is long, causes certain harmful effect to environment.The heavy metal wherein contained, is difficult to remove in composting process, also limit the application of its resource, particularly Land_use change.
Antibiotic just can suppress or affect with humble concentration the chemical substance that it plants biological function.China is antibiotic production and uses big country, within 2012, produces about 210,000 tons of antibiotic raw material per year, produces bacterium slag about 5,000,000 tons (moisture content 80%).The Ministry of Agriculture of the People's Republic of China, MOA in 2002 No. 176 bulletin, listed in various antibiotic filter residue wherein in " forbidding the types of drugs catalogue used in feed and animal drinking water ".The mycelia waste residue producing antibiotics generation is listed in as " hazardous waste " " National Hazard refuse register ".
On February 19th, 2013, U.S.'s New York Times has reprinted " dialogue " magazine article that Australian associated university establishes, this article points out the danger " unrestricted " using antibiotic to bring in Chinese pig farm, " may be spread to the whole world by muck and fertilizer residue thing ".
Article refer to a research report of eight China and U.S.A scientists.This research report is pointed out, Chinese pig farm uses antibiotic to cause the appearance of antibiotic resistance genes in a large number, gives " whole world mankind bring potential health risk ".
Analyze the muck in three China Business pig farms together from the Chinese Scientists of the Chinese Academy of Sciences and their colleague in Michigan State University---they by these muck be not fed through from those of China antibiotic pig manure and with from " not comtaminated forest " inner soil, compare.Final result is: they have found the antibiotic resistance genes of 149 kinds " uniquenesses " in the pig manure on business pig farm.
Research shows, due to abuse of antibiotics in husbandry sector, can cause in pasture ambient air and soil, surface water and groundwater and in the meat of retail and bird, or even be flooded with antibiotic everywhere in wild animal body.These antibiotic can by all means, at people's body accumulation.It not only can cause organ generation pathology, and human body can be become the subenvironment of a cultivation " superbacteria ", thus harm humans and animal itself.More fearful, abuse of antibiotics also can cause the exhaustion of antibiotic resource." new ' superbacteria ' also can occur successively, and in perhaps 10 years ~ 20 years, now all antibiotic all will lose effect to them." plant's periphery sewage flows over, foul smell sky, have a strong impact on ecological environment and view, the daily life of resident and the health of health, directly cause pollution of area source and body eutrophication; The residual soil that enter such as agricultural chemicals, veterinary drug and heavy metal, have influence on the quality of agricultural product on the one hand, increase the drug resistance of edaphon on the other hand.
Along with the expanding day of city size and the fast development of economy, the quantum of output of municipal sludge constantly increases, and bio-pharmaceuticals, intensive culture industry development, the organic waste of annual generation, not only containing a large amount of N P and K and medium trace element, total nutrient (pure amount) about 7,000 ten thousand tons, the national chemical fertilizer application total amount 6,600 ten thousand tons (pure amount) more than 2012." vitalize storage, make good use of increment ", if the innoxious and resource of fine organic waste, not only solve the environmental pollution caused thus, also can leave some natural resources for descendants.
The method of current removal heavy metal mainly contains chemical method and bioanalysis.Chemical method first the acidity of mud is reduced with sulfuric acid, salt action, chelating agent and surface acid or nitric acid, pass through dissolution, then chlorination, ion exchange, acidization is passed through with complexing agents such as EDTA, heavy metal is wherein separated, makes the metallic compound of indissoluble state form soluble metal ion and metal complex.Biological method mainly refers to bioleaching, utilize the direct effect of microorganism or the indirectly-acting of its metabolite, produce oxidation, reduction, complexing, absorption or dissolution, slightly solubility heavy metal in mud is extracted into liquid phase from solid phase, then is removed by Separation of Solid and Liquid.

2can active hydroxyl free radical be produced, thus cause and propagate radical chain reaction, accelerate the oxidation of organic matter and reducing substances.Be swift in response because Fenton reagent has, the reaction condition such as temperature and pressure relaxes and the advantages such as non-secondary pollution, over nearly 30 years, its application in Industrial Wastewater Treatment is more and more subject to extensive attention both domestic and external.Be specially adapted to that some refractory is managed or to the virose industrial wastewater of biology process.Because Fe
2+existence form is in the solution limited by the pH value of solution, so Fenton reagent is only had an effect in acid condition, in neutrality and alkaline environment, and Fe
2+can not catalysis H
2o
2produce OH.Researcher generally believes, when pH value is in 2 ~ 4 scopes, oxidized waste water treatment effect is better, when optimum efficiency appears at pH=3.Therefore first need to add mineral acid acidified mud, make Treatment of Sludge operating cost high.
The organic wastes such as sewage plant sludge, bio-pharmaceuticals factory zymophyte slag, plant's fowl and animal excrement are class high-quality organic resources, but due to the heavy metal, the antibiotic residue that wherein contain, existing composting technology, floor space is large, easily pollute surrounding enviroment, and composting technology is difficult to remove to the heavy metal in organic waste, limit the application of its resource, particularly Land_use change.
Be disclosed on June 30th, 2010, patent CN101759337A discloses the method that a kind of biological acidification-fenton-type reagent coupling improves excess sludge dewatering, in the method, by adding acidophilic bacteria in sulphur powder, ferrous sulfate domestication sewage in primary mud, comprise the acidophilic bacterias such as the bacillus of Thiobacillus ferrooxidans and sulfur oxide sulphur, make primary mud acidifying drop to pH2 ~ 3, then add H
2o
2, thus form Fenton reagent, cause the partially oxidized decomposition of sludge bacteria soma, thus improve activated sludge thalline dewatering efficiency, obtain moisture content 65 ~ 75% dewatered sludge.This patent is used for excess sludge and improves dewatering, solves traditional F enton agent treatment sewage and need add inorganic acid adjustment pH, reduce operating cost.The bacillus of Thiobacillus ferrooxidans and sulfur oxide sulphur belongs to aerobic bacteria, excess sludge solid content is less than 5%, ventilation oxygen supply can be adopted to realize the biological acidification of excess sludge, and the solid contents of dewatered sludge, bio-pharmaceuticals zymophyte slag, fowl and animal excrement is generally 15% ~ 20%, be difficult to reach aerobic fermentation.Again because excess sludge volume is large, be more than 8 times of dewatered sludge volume, also containing various pathogen, cause that acidifying acclimation period is long, equipment investment is large.
Be disclosed on August 16th, 2006, the a kind of of patent CN1817819A can prepare the method for organic fertilizer by rotten organic waste without fermentation process, disclose one and add acidolysis agent the mixed solution of nitric acid or hydrochloric acid or sulfuric acid or the described material---, add nertralizer again---ammonium hydrogen sulfate or calcium magnesium phosphate or magnesia or calcium oxide, then drying produces the method for fertilizer.This method has the fast advantage of processing speed than physics and microbiological treatment mode, but adopts acid solution to process organic waste, and because organic waste material particle is uneven, therefore, process exists uneven, affects product quality.Heavy metal and other material stripping also to be caused in organic pollution in organic materials, and not easily separated, the corrosion that equipment is very large can be caused again.
