An optimal design of wastewater reuse for a University is concerned in this paper. The raw water and the capacity of wastewater reuse were determined according to the wastewater characteristic of a university; the treatment process was chosen by building a cost-benefit model; and the modeling test was performed about the operation effect of the proposed project and the recommended water quality of reclaimed water. It is estimated that 3.4×10^5 m^3/a tap water and 6.1×10^5 Yuan/a will be saved if the project was put into operation and the proposed project will reduce the total quantity of pollutant efficiently and bring lots of social and economic benefits. 展开更多

Based on the panel data of China's 34 industrial sectors during 2005-2013, this paper tests the water pollution effects of SOE ownership diversification in China. The result shows that in general, greater state ownership and less private ownership in a sector will lead to lower water pollution intensity. Test of threshold effect shows that, irrespective of its current level, an increase in state ownership helps improve the environment by different degrees. When pollution intensity is low, ownership diversification helps reduce pollution intensity; when pollution intensity is high, state ownership is the optimal choice for mitigating pollution. This paper's findings suggest that while advancing the mixedownership reform of SOEs, China cannot relax the environmental responsibilities of SOEs, and still less should economic interests override environmental concerns. 展开更多
