Problems solved by technology

However, due to the influence of climate and source, there will be certain differences in the types and quantities of microorganisms in different batches of natural fillers, and it is difficult to guarantee the effect and time of direct use
Moreover, traditional argillaceous fillers (soil, compost, peat, etc.) are easy to be compacted after a period of use, resulting in high resistance, and the fine particles formed by the decomposition of argillaceous minerals by microorganisms are easy to lose with the liquid phase; woody fillers (sawdust, bark, etc.) plant fibers are perishable and prone to collapse after running for a period of time; sintered inert fillers such as ceramsite and perlite lack nutrients, have low porosity and high cost

Embodiment 1

[0019] 1. Preparation of biocomposite fillers.

[0020] The filler main body is a mixture of 75% calcium carbonate, 2.5% diammonium hydrogen phosphate, 20% bark powder and 2.5% urea.

[0021] Binder by weight percentage, ethylene / vinyl acetate 30%, Na 2 O nSiO 2 / K 2 O nSiO 2 For a mixture of 70%, the total amount of binder is 30% of the filler body by weight.

[0022] Mix the filler body in the container for 10 minutes, add the binder, and then add water that is 80% by weight of the filler body. Put the mixture into a mold and extrude it into pellets, and then dry it at 90°C for 1 hour for later use.

[0023] 2. Fermentation of deodorizing compound bacterial agent.

[0024] (1) Prepare liquid medium. The liquid culture medium is an aqueous solution containing 0.5% of glucose, 0.5% of beef extract, 0.5% of sodium thiosulfate, 0.2% of potassium dihydrogen phosphate, and 0.02% of magnesium chloride (containing 6 parts of crystal water) by weight percentage, and does not ...

Embodiment 2

[0029] 1. Preparation of biocomposite fillers.

[0030] The main body of the filler is a mixture of 80% calcium carbonate, 5% diammonium hydrogen phosphate, 10% bark powder and 5% soybean meal powder in terms of weight percentage.

[0031] The binder is 100% ethylene / vinyl acetate by weight percentage, and the total amount of the binder is 20% of the filler main body by weight percentage.

[0032] The filler body was mixed in the container for 15 minutes, the binder was added, and then 70% water by weight of the filler body was added. Put the mixture into a mold and extrude it into a cylindrical shape, and dry it at 60°C for 5 hours before use.

[0033]2. Fermentation of deodorizing compound bacterial agent.

[0034] (1) Prepare liquid medium. The liquid medium is an aqueous solution containing 1.0% of glucose, 1.0% of beef extract, 0.5% of sodium thiosulfate, 0.2% of potassium dihydrogen phosphate, and 0.02% of magnesium chloride (containing 6 parts of crystal water) by we...

Embodiment 3

[0039] Put equal volumes of the biological composite filler (biological filter bed A) and bark (biological filter bed B) into two identical biological filter bed test devices, and adopt natural stacking method without compaction. The filler used in A is prepared according to the method described in Example 2, and the deodorizing composite bacterial agent (prepared according to the method described in Example 2) that accounts for 0.3% of the total volume of the biofilter tank filler is added; the bark used in B does not add any deal with. The air flow rate during the test is 1m 3 / h, containing hydrogen sulfide 500mg / m 3 , Ammonia 500mg / m 3 , continuously fed for 10 weeks, the removal effect of the two filter beds on hydrogen sulfide and ammonia and the pH value of the system are shown in figure 1 and figure 2 .

[0040] Compared with the biological filter bed of group B using only bark, the hydrogen sulfide removal effect of group A using the biological composite filler ...

Abstract

The invention discloses a deodorization composite biological stuffing as well as a preparation method and application of the same. The deodorization composite biological stuffing comprises a stuffing main body and an adhesion agent, wherein the adhesion agent takes account for 10-40% of the stuffing main body in usage amount by weight percentage; in percent by weight, the stuffing main body comprises 70-80% of calcium carbonate, 5-10% of diammonium phosphate, 10-20% of bark powder, 0-5% of urea and 0-5% of the soybean meal; and in percent by weight, the adhesion agent comprises one or more of 30-100% of ethylene / vinyl acetate, and 20-70% of Na2O nSiO2 / K2O nSiO. By the steps of mixing, extrusion forming, drying and the like, the stuffing main body and the adhesion agent are prepared to the deodorization composite biological stuffing. The stuffing is matched with deodorization microorganism for use, second fermentation liquor obtained from the deodorization microorganism which is subject to seed cultivation and fermenter cultivation is uniformly scattered on the stuffing, and after growing, the microorganism can be used for deodorization work. The deodorization composite biological stuffing has the advantages of being excellent in deodorization effect and long in using time which is improved by 30% compared with that of the way using bark as stuffing.

Description

technical field [0001] The present invention relates to a deodorizing filler and its preparation method and application, in particular to a deodorizing composite biological filler and its preparation method and application. Background technique [0002] All substances that stimulate the smell of olfactory organs are called odor pollutants, among which hydrogen sulfide, ammonia, methane, mercaptans and phenols are more harmful to humans. In addition to causing unpleasant feelings such as psychological disgust, foul-smelling pollutants can also cause symptoms such as nausea, headache, and loss of appetite. Biological filtration method is a relatively new air pollution control method, which uses microorganisms to degrade or transform volatile organic compounds, hydrogen sulfide, and ammonia. It has high treatment efficiency, low infrastructure and operating costs, no need to add chemical reagents, and no secondary pollution. Etc. [0003] In the biological filtration method, ...
