摘　　要：目的探讨高等学校污水再生利用的可行性。方法以陕西某高校为例,采用类比分析法和效益分析方法。结果某高校除去部分较难处理污水,如冲厕所产生污水、厨房污水等,可用污水为2 528 m3/d,占总污水量的67%,经处理后得到可用水约2 000 m3/d,完全满足该校区1 658 m3/d杂用水量的预算。该校区如果实施污水再生利用,每年可以节省绿化、洗车等杂水费用约52.2万元,20年收益为1 044万元。其污水再生处理工艺适合采用生物接触氧化法。结论在高等学校实施污水再生利用是必要的,而且技术是可行的。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 m^3/ d,composing 67% of total wastewater. And water able to be used after cleansed in 2 000 m^3/d,which can satisfy the budget amount of 1 658 m^3/d of the university. If the wastewater is recycled,5.22 × 10^5 RMB per year can be saved, and the total benefits of 20 years will reach 1. 044 × 10^7. The best technology of wastewater recycle is biological contact oxidation. Conclusion Wastewater recycle in university is necessary and feasible in technology.
