Embodiment 1

[0030] A kind of method utilizing composite bacterial agent to control rubbish odor, it comprises the steps:

[0031] 1) Add the compound bacterial agent to 10 times the weight of water at 30-35°C, and stir at 200rpm for 10min to obtain a dilution;

[0032] 2) Spread the garbage to a thickness of 30cm, and then spray it with 90g of diluent per square meter, and the treatment time is 72h;

[0033] The composite microbial agent is prepared according to the following process:

[0034] Aspergillus niger seed liquid (1 × 10 8 cfu / ml) and Trichoderma viride seed solution (1×10 8 cfu / ml) were mixed according to the volume ratio of 1:3, and then transferred to the fermenter for 24 hours according to the inoculation amount of 10% volume ratio to obtain the mixed fermentation broth of Aspergillus niger-Trichoderma viride;

[0035] The culture medium components of the fermenter are: molasses 10wt%, cornstarch 3.5wt%, glucose 2.0wt%, sodium dihydrogen phosphate 0.2wt%, magnesium sulfat...

Embodiment 2

[0042]A kind of method utilizing composite bacterial agent to control rubbish odor, it comprises the steps:

[0043] 1) Add the compound bacterial agent to 10 times the weight of water at 30-35°C, and stir at 200rpm for 10min to obtain a dilution;

[0044] 2) Spread the garbage to a thickness of 40cm, and then spray it with 90g of diluent per square meter, and the treatment time is 72h;

[0045] The composite microbial agent is prepared according to the following process:

[0046] Aspergillus niger seed liquid (1 × 10 8 cfu / ml) and Trichoderma viride seed solution (1×10 8 cfu / ml) were mixed according to the volume ratio of 1:3, and then transferred to the fermenter for 24 hours according to the inoculation amount of 10% volume ratio to obtain the mixed fermentation broth of Aspergillus niger-Trichoderma viride;

[0047] The culture medium components of the fermenter are: molasses 10wt%, cornstarch 3.5wt%, glucose 2.0wt%, sodium dihydrogen phosphate 0.2wt%, magnesium sulfate...

Embodiment 3

[0054] The deodorizing effect test of the composite bacterial agent prepared by the embodiment of the present invention 1:

[0055] Mix 3000kg of rotten municipal solid waste evenly, divide them into 3 parts on average, each 1000kg, and place them in 3 closed rooms of the same size respectively, which are the test group, the positive control group and the blank control group; the treatment method of the experimental group can be found in Example 1, the positive control group uses commercially available EM composite bacterial agents, and the control group does not add any bacterial agents. After 72 hours, take samples at different collection points around the garbage, and measure NH 3 、H 2 S removal rate, odor concentration. NH 3 Using sodium hypochlorite-salicylic acid spectrophotometry, H 2 S adopts polyvinyl alcohol ammonium phosphate absorption-methylene blue colorimetric method, and the odor concentration is measured by XP-329IIIR aroma and odor concentration detector....

Abstract

The invention belongs to the technical field of environmental protection and discloses a method for managing the rubbish stink through complex microbial inoculants. The method comprises the following steps that (1) the complex microbial inoculants are added into 30-35 DEG C water of the weight of 10 times that of the complex microbial inoculants, stirring is conducted for 10 min at 200 rpm, and a diluent is obtained; and (2) rubbish is spread into the thickness of 40 cm, then spraying is conducted according to the adding amount that 90 g of diluent is used in each square meter, and treating time is 72 h. According to the method, the complex microbial inoculants are adopted for treating the rubbish stink, ammonia, hydrogen sulfide and other gases can be removed effectively, the stink removing effect is good, and operation is simple and feasible.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a method for treating garbage odor by using a compound bacterial agent. Background technique [0002] With the continuous development of the urbanization process, more and more people gather in the city, and the municipal solid waste is also increasing at a rate of more than 10% per year. The generation of municipal solid waste and the environmental pollution it brings have attracted people's attention, especially at the garbage collection point in the city center and the transfer station of urban solid waste. It will have a certain impact on the quality of life of residents and the local ecological environment. If the management of municipal solid waste collection and transfer is not standardized, it will seriously damage the ecology of the city and cause people's psychological unhappiness. [0003] At present, the commonly used methods at home and...
