Background technology
Frequent day by day along with the human production activity brings various pollutions, as soot, lavatory, plant, slaughterhouse etc., can produce various stenches, serious environment pollution.Because floor spaces such as soot, plant are big, general deodorizer can not be effective at all, and the deodorization time is also quite slow.At present, also do not have specially, and in the current society more and more higher environmental quality requirement at the deodorization technology of driving away these place stinks, to these large tracts of land stink sources carry out effectively, fast deodorization becomes and presses for.
Summary of the invention
The objective of the invention is to problem at the prior art existence, invent and a kind ofly be used for the soot with sodium humate/potassium as biochemical deodorizer and carry out deodorization, this deodorizer preparation and deodorizing method, the deodorizer raw material sources that adopted are wide, low cost of manufacture, deodorization is rapid, effective.
At first, we analyze the generation of foul smell such as soot, plant.These foul smell mainly result from the corruption of the organic component in the refuse and decompose, and generally be divided into three phases: the phase I is the hydrolysis acidification stage, and second stage is for producing methane phase, CH in the gas
4Account for more than 50% of cumulative volume, its character and characteristics have influenced the main character of gas.
Phase III, most of degradable Organic substance transforms NH
3And CO
2After be released in the air, be the steady statue of gas.
Analyze this gas, its composition is broadly divided into three classes:
The main component of the first kind comprises methane CH
4With carbon dioxide CO
2, account for more than 95% of gas gross, there is the collection of specialty to utilize pipeline to methane gas in the general refuse landfill.
Second class comprises H
2S, NH
3, SO
2Deng foul smell gas, account for below 5% of gas gross.H
2S is a kind of colourless have zest and asphyxiant toxic gas, and it mainly enters body by respiratory tract, people's death by poisoning is died after sucking a large amount of hydrogen sulfide.NH
3Very harmful to the mankind, moderate intoxication can cause diseases such as pneumonia, and severe patient may be gone into a coma, shock or reflexive respiratory arrest.SO
2Be a kind of colourless toxic gas that penetrating odor is arranged, serious poisoner can cause the stupor of suffocating.
The 3rd class is a micro constitutent, as organic acids, saccharide and sulfur-bearing, nitrogen compound, accounts for 1% of gas gross, and they also can give out unpleasant foul smell.Though this type of gas constituent content is low, toxicity is very strong, has multiple " three cause " material, and health is had serious threat.
At above-mentioned character, the composition of odorous gas, the present invention realizes the object of the invention by the following technical solutions:
The present invention adopts sodium humate/potassium to be applied to the biochemical deodorization in soot as deodorizer.
This biochemistry deodorizer select mud coal, brown coal and weathered coal for use any one be raw material, add alkali again, by the ratio of coal, alkali, water is 100: 8.5～9.5: 400～500 to react in the reactor of belt stirrer, in about 1 hour of response time, temperature is controlled at 70～130 ℃, and pH value is controlled at 9～11, after reaction is finished, stop heating, leave standstill, allow its precipitation obtain the gluey deodorizer of sodium humate/potassium.
If further drying, make that humic acids content is greater than 50% in the solids behind powder or graininess sodium humate/potassium deodorizer raw material drying, water-insoluble is less than 15% in the solids.
It is as follows to utilize above-mentioned deodorizer to carry out the deodorant method:
When deodorizer is sodium humate/potassium Colloidal fluid, be 1 just with sodium humate/potassium Colloidal fluid deodorizer and water weight ratio: the 50-100 dissolving, be sprayed on the rubbish, carry out deodorization.
After sodium humate/the potassium Colloidal fluid had passed through drying, then with powder or graininess sodium humate deodorizer and water 1: 10 by weight～20, composite was Colloidal fluid, and be 1 by Colloidal fluid and water weight ratio again: 10-20 is sprayed on the rubbish, carries out deodorization.
In order to reach better deodorizing effect, powder sodium humate/the potassium of also available 1 part of weight and 25-150 part water, adding about 1 portion of sucrose or fructose, pack in the sealed container, anaerobic fermentation is about 20 days, to producing sour-sweet wine flavour, as the activating solution of deodorizer under 25 ℃ of-35 ℃ of conditions, after pressing activating solution and water weight ratio 1: 30-80 preparation again, sprinkling rubbish is earthed up then and is rolled.Through biofermentation, its Use Limitation fruit is better like this.
The resulting sodium humate of the present invention/potassium deodorizer is to be primary raw material with mud coal, brown coal, weathered coal.Humic acids is a kind of natural organic macromolecule chemical compound, it is generally acknowledged that it is a complex complicated, the inhomogenous hydroxy benzenes carboxylic acid of molecular weight, and its mean molecule quantity is between 1000-1400.Its main component is: carbon C, oxygen O, hydrogen H, nitrogen N and sulfur S, and the molecular formula of humic acids simply is expressed as:
