Environmental Cost-benefit Investigation And Analysis Of Sewage Polution-free Treatment Projects In S Farms

In recent years,with the improvement of living standards,Chinese consumers have increased their demand for meat,eggs,and milk,both in terms of quality and quantity,along with the vigorous development of animal husbandry.It is the heavy burden that the livestock husbandry pollution causes on the ecological environment.The first national update of pollution source census shows that the major water pollutant COD in animal husbandry in C hina has surpassed the industrial discharge of this pollutant.At the same time,animal husbandry is also an important source of gas pollution.The data shows that if the use of land for animal husbandry occupies land and changes in land use are taken into account,the major greenhouse gas emissions from animal husbandry have reached more than 10% of the total human greenhouse gas emissions.It can be seen that the animal husbandry has been a huge threat to the ecological environment at present,and extensive feeding methods for livestock and poultry need to be improved.With the improvement of China's industrial structure and transformation and upgrading,the society has gradually paid attention to the pollution of animal husbandry.Through the scheduling of livestock husbandry and environmental protection agencies,the government and large,medium,and small-scale farms are investing more and more funds to control livestock.Industry pollution.However,when we pay a large amount of environmental protection costs,the degree of pollution in the animal husbandry has been improved to a certain extent.This paper focuses on this issue and tries to provide some theoretical help for the pollution control of livestock husbandry through field investigations and research and analysis.This article first investigates and analyzes the cost and effectiveness of environmental protection of S farms from a microscopic level,then collects and collates the relevant data of the site,and finally summarizes and summarizes the current pollution control ideas and society in animal husbandry in our province.The contradiction of the status quo,based on advanced foreign theories,combined with the actual situation in our province,the overall consideration of the healthy development of animal husbandry and the growing awareness of environmental protection work,and put forward a good policy for the sustainable development of animal husbandry for the whole society.
