At present, the total annual fecal production of domestic chickens and other poultry in China is as high as 580 million tons, and the total annual discharge of fecal water is as high as 6 billion tons. However, the amount of fecal water treated by engineering measures in the city only accounts for 25% of the emissions. Due to insufficient funding, the vast majority of these chicken farms have inadequate treatment and utilization of their manure, resulting in increasingly serious pollution of the surrounding environment. Many chicken farms have a foul odor, swarms of mosquitoes and flies, serious nitrate levels in groundwater, and the prevalence of infectious and parasitic diseases in a few areas. The large-scale sewage treatment has reached a point where it is necessary to treat it.
The process flow of harmless treatment of chicken manure for organic fertilizer production equipment: After the fermentation of organic fertilizer raw materials is completed, they enter the organic fertilizer crusher and are crushed into powder. The powder enters the organic fertilizer mixer and auxiliary materials are added for stirring. After stirring evenly, it enters the organic fertilizer granulator to make particles. The particles are then dried in the dryer to reduce the moisture content of the particles to 10-20%, and then cooled in the cooling machine, After the cooling is completed, it enters the screening machine for screening. The unqualified products screened out are re fed into the crusher for crushing using a return belt conveyor. The finished products screened out can be directly packaged.
The production line of chicken manure organic fertilizer has a compact structure and advanced technology. It uses harmless live bacterial preparations to treat livestock and poultry manure, and undergoes biological fermentation under the action of various beneficial microorganisms. After fully decomposing the organic matter, nutrients are released, and the resulting biological heat and high-temperature fermentation process can kill bacteria and insect eggs, detoxify and deodorize, purify the environment, and achieve harmless, resource-based, and industrialized treatment. The energy consumption is low, and the product quality is stable.
The complete set of organic fertilizer equipment is not what we imagine to be a fixed equipment, but needs to be determined based on the on-site site and materials. For example, chicken manure has a relatively high moisture content, and during fermentation, the moisture must be reduced. Corn cobs and other materials that can be crushed with straw can be added, otherwise they cannot be granulated. Sheep manure is relatively dry, and if the moisture is controlled during fermentation, it can be directly granulated without the need for straw, The equipment used varies depending on the process.
