Research On The Faeces Pollution Of Livestock And Poultry In Huhhot

Animal husbandry industry plays an important role in agriculture and the whole national economy., However, in recent years, with the explosive growth of the Animal industry,potential environmental pollutioncaused becomes more serious as people's environmental protection awareness increases by raising of animal husbandry. Currently, Pollution caused by livestock and poultry breeding has been one of the leadingsources of environmental pollution in rural areas of China. It engenders direct or indirect negative effects to water, atmosphere, soil, human health and ecosystems.Huhhot is the the capital of Inner Mongolian Autonomous Region. Resently,the consumptive structures changed rapidly owing to economic development and improvement of living conditions. As a result, livestock developed very quickly and became a pillar industry in rural economy. At the same time, many Livestock and poultry manure became contaminative sources without decontaminating function from croplands. The environmental pollution problems became increasingly serious. In the study,According to the calendar year of livestock and poultry data, Reference to relevant literature at home and abroad, Consider the situation of local animal husbandry. through the estimation methods of yearly discharge amount of animal manure and the determination of excretion parameter of animal manure, and take into account Huhhot animal husbandry. Used pig fecal equivalent and effective area under culti-vation, and calculated the loading amounts of domestic animal feces in Huhhot, The loading amounts of domestic animal feces pig fecal equivalent and effective area under culti-vation, The average value of Equivalent loading amount of pig dropping is 29.5 t/hm~2. most areas Beyond the average value. The N and P loading of dorncstic animal feces per area,Average Value is 0.20 t/hm~2,0.06 t/hm~2. The distribution in accord with pig fecal equivalent and effective area under culti-vation。At the same time, we had selected the two farms for production of sewage pollution coefficient and determination of the accuracy of the estimates for research. Moreover, analysis the reason of the serious pollution in recent years for livestock and poultry from the existing policies and regulations.keeping the layout and the use of bases and so on. And make suggestions for the treatment of the faeces pollution of livestock and poultry.In Management,We need to strengthen the comprehensive management of livestock and poultry manure, and Pollution Control act to develop animal husbandry, livestock and poultry manure to improve and support the comprehensive management of facilities.In Technology, We need to Improve the technical of resources for the realization reduction, and eco-friendly. The formation of rational layout, facilities, cleaner production, emission standards new pattern of livestock production.
