A study on how to deal with wastewater recycle in instifutions of higher learning

Aim Feasibility of wastewater recycle in university was discussed.Methods Take one university of Shaanxi as an example,analogical analysis and cost-benefit way were used.Results Except some wastewater difficult to be dealt with such as toilet wastewater and kitchen wastewater,wastewater able to be recycled is 2 528 m3/d,composing 67% of total wastewater.And water able to be used after cleansed in 2 000 m3/d,which can satisfy the budget amount of 1 658 m3/d of the university.If the wastewater is recycled,5.22×105 RMB per year can be saved,and the total benefits of 20 years will reach 1.044×107.The best technology of wastewater recycle is biological contact oxidation.Conclusion Wastewater recycle in university is necessary and feasible in technology.
