Abstract


The environment is the material basis of the economy , protect the environment, promote economic development , but also restricts the role of the environment to the economy , and promote economic development on the environment . This shows that the environment is essentially an economic issue , environmental issues must be considered together with economic and social problems , in order to obtain the economic, social and environmental development . High concentrations of arsenic-containing waste water treatment is a difficult environment treatment project , three different processing methods of the lime - molysite law , and - oxidation - flocculation and sulfide precipitation of high concentrations of arsenic-contaminated wastewater pilot study Applied environmental Economics of the basic theory of three different treatment methods for waste water containing arsenic pollution costs, benefits , costs of environmental economic analysis and evaluation , and focus on the benefit-cost analysis of the basic principle of the waste water containing arsenic analysis of qualitative description and quantitative research . Through a system of of arsenic wastewater treatment technology analysis and experimental research , the loss estimates of pollution and pollution control benefit analysis . The benefit-cost ratio of different treatment programs than the election, and the lowest cost of processing and the best treatment effect for control indicators , and finally to determine the best solution for high concentrations of arsenic wastewater treatment and - oxidation - flocculation . For of arsenic pollution control and governance , effective protection of the environment to provide an economically viable passing .
