Currently, the demand for Chinese environmental protection talents has following features: The work field of environmental protection moves down, so the basic level of environmental protection talents are much needed. Also, the construction and management on urban environmental protection infrastructure is enhanced, so the facility operation and management personnel are much needed. And the structure of environmental protection industry becomes increasingly complicated, so the new type of interdisciplinary talents are much needed. In order to meet the demand for environmental protection talents, the countermeasures about talent training are shown as below: we shall timely adjust the overall arrangement of subject and major based on the demand for environmental protection industry, and the stakeholders shall have a comprehensive cooperation to establish a long-term mechanism for environmental protection talents training. © (2014) Trans Tech Publications, Switzerland.

An analytical model is established to predict the seepage performance of the liner system composed of a compacted clay liner (CCL) covered by a geomembrane (GM). The contaminant of Pb2+ diffusing through the geomembrane is assumed to be a steady-state process. The liner systems with low leakage performance are usually utilized in the municipal solid waste landfills to prevent the contaminants of the leachate from polluting the groundwater and soil beneath the landfill. To investigate the seepage rate of the Pb2+ in the liner systems of the landfill considering the effects of the geomembrance, the influence of the geomembrance on the seepage performance of the liner system is studied. Parametric analyses are conducted to study the effects of the thickness of GM and the number of defects in the GM on the leakage performance of the liner system. In conclusion, some suggestions for the design of the municipal solid waste landfills are proposed based on the analyses results. © (2014) Trans Tech Publications, Switzerland.

During the last decades, especially the Eleventh Five-Year Plan period, China vocational education on environmental protection has made remarkable progresses. The vocational education on environmental protection has developed fast and spread widely, and formed an integrity system with various kinds of types. On the basis of analyzing the development status of vocational education in the field of China environmental protection and the cooperative mechanism and operative mode of production, teaching, research and application of partial higher vocational environmental education and environmental majors at home, this paper describes the history and development of vocational education on environmental protection in China and conducted a case study of vocational education on Changsha Environmental Protection Vocational College (CEPVC). The purpose is to identify lessons from past experience in vocational education to inform future development. The retrospective nature of this paper focuses attention on what has been done in the past, and to a lesser extent on the nature of current state. There are significant issues in vocational education, for example, the contribution of training to informal sector employment, that fall largely outside of vocational education experience, this is important for the future. © (2012) Trans Tech Publications, Switzerland.

With the rapid development of science and technology, we could enjoy more and more convenience of modern technology, we have to face the negative influence of modern technology on environment. The Kitakyushu city used to be one of most heavily air-polluted regions in Japan. Through decades of improvement on the environmental education, the Kitakyushu city become the 'Demonstration city on environment protect of Japan' and the 'Typical city of environmental governance' award by the United Nation. These effective measures include increasing the investment in the environmental education and scientific research, extensively conducting environmental education to improve the public awareness of environmental protection and promoting the integration and transformation of production, knowledge and research on environmental protection. This paper studied the main steps that the Kitakyushu city take to improve its environment pollution and analyze the revelation of these useful measures to China's environmental education. © (2012) Trans Tech Publications, Switzerland.

The municipal solid waste (MSW) landfills commonly utilize a low permeability liner system to control the escape of contaminants from the landfill. The clogging of the liner system because of leachate mound leads to increased hydraulic head of the leachate collection system, which results in higher pressure for the anti-pollution performance of the liner system. To study the anti-pollution performance of the geomembrane (GM) over a compact clay layer (CCL) liner system considering leachate mound, the minimum requirements for the design of the liner systems are introduced based on the specifations from three countries, including China, USA, and Germany. Then we adopt the one-dimensional finite layer model to analyze the anti-pollution performance of the GM+CCL liner systems. Parametric analyses are conducted to study the influence of the thickness of GM and the thickness of CCL etc, on the anti-pollution performance of the liner system. It is concluded that the GM+CCL liner system designed according to the minimum design requirements of Germany provide the best anti-pollution performance. The key factors affecting the critical time of the liner system are the hydraulic head, the number of defects on the GM, the thickness of the CCL and the hydraulic conductivity. In addition, some advices for the corresponding design provisions are proposed based on the parametric analyses. © 2013, EJGE.
