Background
The foul smell is a general name for all gases which stimulate olfactory organs to cause people to be unpleasant and harm the living environment of people. Malodor is one of seven public hazards recognized in the world, second only to noise. The malodor can cause nausea, dizziness, vomiting and other reactions, and can also cause respiratory diseases, cardiovascular diseases and other diseases of human beings seriously. Due to high water content and high organic matter content, the kitchen waste is extremely easy to decay, odor is emitted, and insect flies are bred.
There are three main methods of deodorization at present: physical, chemical and biological methods. The physical method and the chemical method are suitable for occasions with high odor pollutant concentration, and have the advantages of high odor treatment efficiency, short treatment residence time, quick start and the like; but also has the defects of easy secondary pollution caused by treatment, high equipment cost, high operation requirement and the like.
Compared with physical and chemical methods, the biological deodorization method does not need to add chemical substances in the process, can be carried out at normal temperature (10-40 ℃) and pressure, has lower cost and simpler operation compared with the physical method and the chemical method. And the microbial degradation is usually oxidation reaction, and the final products of odor are carbon dioxide, water, sulfate, nitrate and the like, so that secondary pollution can not be caused. The microbial deodorization mode adopted by refuse disposal places such as refuse landfills, refuse compression stations and refuse compression vehicles is similar to the deodorization mode of livestock farms, and the microbial deodorization mode is mainly used for spraying biological viable bacteria.

Patent document CN 110314529 a discloses a composite microorganism deodorant, comprising composite microorganisms and an enzyme activator, wherein the composite microorganisms consist of 17-23% of pediococcus acidilactici, 19-22% of lactobacillus bifidus, 18-21% of lactobacillus acidophilus, 22-28% of alcaligenes faecalis, and 13-19% of rhodopseudomonas palustris; the selected microorganisms mainly comprise garbage filtrate original bacteria and have strong environmental adaptability. The use condition of the microbial deodorant requires that the pH value is 6.5-8.5, the temperature is 28-37 ℃, the deodorization time is 60h, and the use amount is 5-8 vt%.

Crushing the fresh kitchen waste by a stirrer, subpackaging the crushed fresh kitchen waste into 500ml triangular flasks, subpackaging 100g (wet weight) of the fresh kitchen waste into each flask, and setting three parallels in each group of experiments. Then, the microbial inoculum prepared in the example is added in an amount of 10 g/bottle, and only 100g of fresh kitchen waste is added as a blank control. The mixture was left at a constant temperature of 28 ℃ for 48 hours, during which the concentrations of hydrogen sulfide and ammonia gas were measured every 8 hours.
The hydrogen sulfide determination method comprises the following steps: the measurement was carried out with a portable complex gas analyzer PTM-600 in Egyun.

Example 3 Airtight deodorization test Using kitchen waste as substrate
Crushing fresh kitchen waste by using a stirrer, subpackaging the crushed fresh kitchen waste into 500ml triangular flasks, subpackaging 100g (wet weight) of fresh kitchen waste into each triangular flask, and setting three parallels in each group of experiments. Then, the microbial inoculum prepared in example 2 was added in an amount of 10 g/bottle, and a blank control was set. Then the bottle is sealed by three layers of preservative films, and the bottle mouth is fastened by a rubber band. The mixture was placed in an incubator at 28 ℃ and the concentrations of ammonia and hydrogen sulfide were measured after 24 hours.
Three groups of parallel tests show that the degradation rate of the biological deodorization bactericide for hydrogen sulfide in the kitchen waste after being inoculated for 24 hours is 79.23%, and the degradation rate of ammonia gas is 25.71%. From the experimental results, the biological deodorant microbial inoculum prepared from the pichia guilliermondii has obvious degradation effect on odor generated by the kitchen waste, and has better application potential.
Example 4 open odor control test Using kitchen waste as substrate
Crushing fresh kitchen waste by using a stirrer, subpackaging the crushed fresh kitchen waste into 500ml triangular flasks, subpackaging 100g (wet weight) of fresh kitchen waste into each triangular flask, and setting three parallels in each group of experiments. Then, the microbial inoculum prepared in example 2 was added in an amount of 10 g/bottle, and a blank control was set. The sample was placed in a 28 ℃ incubator, the concentration change of hydrogen sulfide and ammonia gas was measured within 48 hours, and the gas concentration was measured every 8 hours, and the experimental results are shown in fig. 3 and 4.
The experimental result shows that the microbial agent has a good inhibition effect on hydrogen sulfide, the concentration of the hydrogen sulfide in the kitchen waste is obviously reduced, and in addition, the microbial agent has a certain inhibition effect on ammonia gas.
Example 5 comparison of odor concentration at different pH with kitchen waste as substrate
Smash fresh kitchen garbage and split charging in 500ml triangular flask with the mixer, every triangular flask partial charging 100g (wet weight) fresh kitchen garbage sets up three experiment group: the pH was adjusted to 6.0, 7.0, 8.0, then 10g of the inoculum prepared in example 2 was added per bottle, three replicates per set of experiments were set up. The changes in hydrogen sulfide and ammonia concentrations were measured over 48 hours, and the gas concentrations were measured every 8 hours, with the results shown in FIGS. 5 and 6.
From the results of the examples it can be seen that the microbial agents release hydrogen sulfide at pH6.0 at concentrations slightly below pH7.0 and 8.0. The ammonia gas concentration is the lowest when the pH value is 6.0, and the ammonia gas concentration is increased along with the increase of the pH value, which also accords with the ammonia gas release rule that the ammonia gas release amount is larger as the pH value is higher, so the odor gas concentration generated by using the microbial inoculum under the condition of the pH value of 6.0 is the lowest.
Example 6 comparison of odor concentration at different temperatures using kitchen waste as substrate
Smash fresh kitchen garbage and split charging in 500ml triangular flask with the mixer, every triangular flask partial charging 100g (wet weight) fresh kitchen garbage, add the microbial inoculum that embodiment 2 prepared with the dosage of 10 g/bottle, set up three group's experiments: the culture medium is respectively placed in constant temperature incubators at 28 ℃, 37 ℃ and 45 ℃, and three experiments in each group are arranged in parallel. The changes in hydrogen sulfide and ammonia gas concentrations were measured over 48 hours, and the gas concentrations were measured every 8 hours, with the results shown in FIGS. 7 and 8.
From the results of the examples it can be seen that the microbial agents release hydrogen sulphide at 28 ℃ at lower concentrations than at 37 ℃ and at 45 ℃. The ammonia gas concentration is the lowest at 28 ℃, and the ammonia gas concentration is increased along with the temperature increase, which also accords with the ammonia gas release rule that the ammonia gas release amount is larger as the temperature is higher, so the odor released by the microbial inoculum at 28 ℃ is lower.
Example 7 influence of microbial inoculum with different inoculum sizes on kitchen waste odor concentration
Smash fresh kitchen garbage and split charging in 500ml triangular flask with the mixer, every triangular flask partial charging 100g (wet weight) fresh kitchen garbage sets up three experiment group: 1%, 2%, 5% and 10% of the inoculum (w/w) were added, three replicates per set of experiments were set up. The hydrogen sulfide and ammonia gas concentration changes within 48h are measured in a constant temperature incubator at 28 ℃, the gas concentration is measured every 24h, and the experimental results are shown in tables 1 and 2.
From the results of the examples, it can be seen that the effect of 10% inoculation is better than that of other experimental groups, and the effect of the inoculation is better for odor concentration.
