The environmental protection measures for realizing resource utilization of organic fertilizer equipment in the production process mainly include the following aspects:
1. Pretreatment of raw materials: through the steps of impurity removal, grinding, mixing, etc., to ensure that the raw materials are suitable for the subsequent fermentation process. After pretreatment, the water content of perishable waste is adjusted to 45%-65%, and then it is composted at high temperature.
2. Control of fermentation process: Use reactor composting technology to carry out aerobic fermentation. By controlling the fermentation temperature and time, the organic matter can be fully decomposed and the pathogenic bacteria can be inactivated.
3. Odor and leachate treatment: Odor and leachate produced in the fermentation process are treated by special treatment equipment to reduce the impact on the environment.
4. Resource utilization: the fermented organic matter can be used as organic fertilizer or cultivation substrate to achieve the recycling of resources. In the case of Guangze County, Nanping City, Fujian province, the annual output of organic fertilizer is about 24 tons, mainly for free use by surrounding farmers, and the leachate is stored and fermented and returned to the field.
Through the above measures, the production process of organic fertilizer production line can not only reduce environmental pollution, but also improve the efficiency of resource utilization and promote the sustainable development of agriculture.
