Example 3
The wood chips of the raw material storage yard are taken and distributed in 4 storage boxes with 8L (each box is 800g of wood chips) and sealed. After 10 days, after the wood chips are naturally fermented, measuring the content of the peculiar smell gas at the top in the storage box. As shown in FIG. 1, FIG. 1 is a diagram of an experimental apparatus in example 3 of the present invention; as can be seen from table 1, during the natural fermentation of wood chips, the gas mainly produced is acid gas such as acetic acid. After the compositions for reducing the peculiar smell of the wood chip storage yard, which are prepared in the embodiment 2 and the comparative examples 4 to 13 of the invention, are added according to different volumes, the amount of generated acid gas is reduced.
