Livestock manure is one the main sources of pollution of the environment, but also a valuable feed or fertilizer resources, through the processing of organic fertilizer equipment can be made into feed or organic compound fertilizer, not only can turn waste into treasure, but also can reduce environmental pollution, prevent the spread of disease, livestock manure harmless treatment common technology:
First, the return of livestock and poultry manure to the field by land reduction method is an important link in China's traditional agriculture, which plays an important role in improving soil and improving crop yield. The soil can obtain fertilizer and purify the manure at the same time, saving the disposal cost of the manure.
Compost fermentation treatment is currently a more traditional and feasible method for the treatment and utilization of livestock and poultry manure. The manure is stacked and fermented, and the temperature generated by itself is used to kill eggs and pathogens, so as to achieve the purpose of harmless treatment.
Third, feed technology (fermentation treatment) livestock manure contains a lot of undigested protein, B vitamins, mineral elements, crude fat and a certain amount of carbohydrates, especially the crude protein content is high, the manure after fermentation by starter culture can become a better animal feed resources.
Fourth, the biological decomposition method uses lower animals such as maggots, earthworms and snails to decompose livestock and poultry feces to achieve the purpose of providing animal protein and processing livestock and poultry feces. First, cattle manure and feed residue were mixed to retting to achieve the physical and chemical indexes required for earthworms to lay eggs, hatch and grow. Then, the decomposed material was laid on the ground with appropriate thickness and put into earthworms for reproduction.
The septic tank is a equipment for treating feces and filtering precipitation. The principle is that the solidified material decomposing and flowing away at the bottom of the pool prevents pipeline blockage and gives the solidified object enough time to hydrolyze. Septic tank is a treatment method to remove suspended organic matter in domestic sewage by using the principles of precipitation, anaerobic and fermentation. The sewage enters the septic tank after 12 to 24 hours of treatment, and the precipitated sludge goes through anaerobic digestion for more than 3 months, so that the organic matter in the sludge is decomposed into stable inorganic matter, and the treated sewage can be purified.
