Under the conditions of separation of ownership, the pay given to managers should be linked with their performance. Therefore, it is extremely important to establish a scientific and effective performance evaluation system for managers. Many companies began to try to establish short-term and long-term incentive plan for managers. The purpose is to through the introduction of a new payroll system promote the behavior of managers remaining consistent with corporate benefits. But the real realization of the plan relies on running of performance evaluation system. Only scientific and fair assessment of manager performance can we implement various salary system on only reliable basis, which is the key importance for the manager performance evaluation.展开更多

Pressures caused by variability in water supply cycles, droughts, pollution, industrialization, increasing domestic and commercial demand, inadequate infrastructure, intense urbanization and population growth, and decrepit distribution networks have led to the increasing exploitation of industrial wastewater. Most industrial process has some negative impacts on the environment especially on a catchment scale i.e. water, air and soil quality. In the context of water resources and environmental protection measures, the term ＂sustainable development＂, a development that is compatible with the future gains and environmental protection, is regulated more and more by law. To comply with these emission-based limit values, so-called ＂end-of-pipe-techniques＂ are used. Experimental results show CBT （continuous biological treatment） processes present secondary measures to purify highly contaminated industrial wastewater.展开更多
