The organic waste used in organic fertilizer equipment is mainly corrosive substances, so we must use closed transport vehicles when collecting and transporting these wastes. These organic wastes are easy to emit odors, which not only causes certain pollution to the environment, but also brings great harm to the human body. Therefore, we must collect and utilize these organic wastes in time.

Although auxiliary materials such as rice husks and sawdust do not produce odor, dust will be generated during the unloading of raw materials. In addition, when using a crusher to crush rice husks, dust and water vapor will be generated during the process of moving rice husks to the storage tank, around the crusher, and when the crushed rice husks are transported.

When crushing prunings, if a shearing crusher is used, basically no dust will be generated, but if the prunings are crushed by a combination of high-speed rotary crushing and air conveying, a considerable amount of dust and noise will be generated. In the mixing equipment, various raw materials are put into the mixer, especially when the compost return material with low water content and the discharge of mixed raw materials, odor and dust will also be generated.

During the fermentation process of organic fertilizer production equipment, the decomposition of organic matter will produce odor mainly composed of ammonia. After various raw materials are put into the one-time fermentation facility, the compost is discharged from the one-time fermentation facility, and repeated operations are performed in the secondary fermentation tank, odor and dust are generated. Due to the decomposition of organic matter, the temperature of raw materials rises, which will produce a large amount of water vapor.

During the repeated operation process, odor, water vapor, high temperature and dust are mixed together, and the water vapor generated in the fermentation chamber will cause the entire fermentation chamber to appear in a state of white fog. The odor and water vapor generated during the fermentation process will be significantly reduced with the end of the first fermentation, and basically disappear when the second fermentation is completed. The compost with less water is accompanied by a decrease in water, and then dust is generated. During the repeated use of the secondary fermentation facility, water-based gas and dust will be generated at the same time.
