How does livestock and poultry dung pollution handle environmental protection？

The common problem of manure treatment farms is probably the problem of livestock and poultry waste treatment. One is that there is no space for accumulation, and the other is that we do not know how to deal with it. The accumulation of livestock and poultry waste for a long time will breed many bacteria, posing a threat to the safety of people and livestock and poultry.  As a waste treatment equipment manufacturers, tongda heavy industry to talk to you about the process of waste treatment. 

1. Chicken manure, as the main decaying material, has a large moisture content, so excess moisture needs to be removed and dried. However, because the drying process is easy to stick, the effect of moisture removal is not very good.  Therefore, we can choose to add straw, rice husk, slag and other auxiliary materials with low water content, and use the organic fertilizer crusher to crush these large auxiliary materials into 3-5cm diameter, so that in the composting process, the porosity of the heap can be increased, which is conducive to the entry of oxygen, and is very beneficial to the propagation of fermentation agent.  

2. During composting, with the increase of composting time and temperature, the porosity of the composting body decreases continuously, oxygen supply begins to be insufficient, fermentation reaction slowly declines, and even anaerobic reaction produces odor. Such composting process does not meet the requirements of environmental protection production.  Therefore, during the temperature rise, it is necessary to use the hydraulic tank turning pile machine to turn the pile, and the height of the turning pile machine can be adjusted according to the number of compost, which is low cost and easy to operate.  

3. After the fermentation and stacking, it can be pulverized again to remove excess debris and bulk materials, so that the processed pig manure fertilizer can be used directly as a base fertilizer.  Chicken manure can also be granulated, processed into chicken manure organic fertilizer granular fertilizer.  If the output of chicken manure organic fertilizer production line is large or you want to achieve automatic production of organic fertilizer, organic fertilizer processing equipment can be added in the later stage: drum dryer, cooler, packaging scale.  Pig manure wants to process and produce organic fertilizer roughly needs to go through the following processes:  

Chicken manure treatment (crushing, turning pile) - raw material screening (sundry treatment) - chicken manure granulation, drying - pig manure organic fertilizer finished product packaging sealing (computer quantitative packaging) - finished product inspection warehousing (laboratory).
