Turning Cow Dung Into Treasure To Form A Circular Economy

A friend who raises cattle often complains that "the environmental protection department has sent a message that if cow dung is not properly handled, the cattle farm cannot go on.". Indeed, in recent years, the cattle industry has developed rapidly. With the development of large-scale cattle farms, the problem of cattle pollution is becoming increasingly serious. The prominent issue is how to deal with cow dung from farms. Many cow dung is left untreated on open spaces, causing air pollution, breeding a large number of mosquitoes and flies, and affecting the surrounding living environment. How to deal with cow dung on the farm, and how to use cow dung for beef cattle breeding?
Treatment method for cow manure in livestock farms: Biogas tank construction: Biogas tank construction is a method of treating cow manure in small cattle farms, using cow manure and pollutants from the cattle farm as raw materials, with an investment of thousands of yuan. This not only solves the fuel source for the masses, but also enables the full decomposition of cow manure. The residue and liquid of biogas are very good organic fertilizers, which can improve the internal quality of fruits and vegetables and reduce investment. However, the small biogas digesters currently built have no power generation function, and are generally suitable for calf farms. Cow dung dehydration: Solid-liquid separation of cow dung is performed using a solid-liquid separator to reduce the weight and processing difficulty of cow dung. The cow dung after solid-liquid separation is more conducive to further processing and transportation.
Cattle manure cultivation and breeding: The combination of cattle farming and planting is a good way to treat cow manure, but the investment needs to increase significantly. A cow should be planted on 3-5 mu of land, which can not only meet the roughage source for raising cattle, but also consume cow dung. Although the overall investment has increased, the cost of raising cattle and cultivating land has declined separately. It is worth noting that cow dung needs to be fully fermented and decomposed before being put into the ground to avoid burning the seedlings. This is also a commonly used method for handling cow dung. Cow dung organic fertilizer: cow dung has high nutrient content, and can be turned into organic fertilizer products after fermentation, which can fluff the soil, improve the soil hardening, chelate trace elements in the soil, and improve soil fertility. At the same time, using cow manure as raw material to produce organic fertilizer has low cost, stable quality, and large market space. Currently, treating cow manure to produce organic fertilizer is a valuable method.
Currently, the effective method for fermenting organic fertilizer with cow manure is to use cow manure fermentation tanks. It is necessary to add fermentation bacteria, and after high-temperature aerobic fermentation, use the thermal energy of microorganisms to assist in electrical energy to carry out three-level atomization deodorization. The discharged air meets the standard, greatly reducing harmful gas emissions and environmental pollution, and fully meeting the requirements of modern green ecological environmental protection.
