Facing the incorporation of high-tech, such as bio-tech andinfo-tech, into agricultural scientific fields and entry of China into WTO, our agriculturehas met some new problems and challenge. Among many agricultural scientific fields,plant protection science is incorporated with more advanced scientific technology and hasa close relation to the international trade.
To solve this problem, by using patent technology of de-sulphurization (Xian Xiangde Environmental Protection Science and Technology Co.,Ltd. ) to treat acid wastewater, the result shown that purified water pH volume is between 9~10, sulfide concentration is less than 60mg/L, ammonia nitrogen concentration is more than 600mg/L .
Based on the objects, property and theoretic foundation of land protection science, this paper dissertates it's content system and study methods,and then puts forward the relationship between the land protection science and related disciplines.
They may be seen both as a vbridge and as a buffer zone protection science from getting completely absorbed by the market.
Reviewing the science and technology achievements in the past 20 years in Shanghai were presented, such as: scored great successes, gathered together strong science and technology forces, modernised the scientific research equipment's gradually, formed environmental protection science and technology information network, obtained a remarkable achievement in international co-operation, and made clear the leading thought of environmental protection work furtherly. Taking the view of science and...
Reviewing the science and technology achievements in the past 20 years in Shanghai were presented, such as: scored great successes, gathered together strong science and technology forces, modernised the scientific research equipment's gradually, formed environmental protection science and technology information network, obtained a remarkable achievement in international co-operation, and made clear the leading thought of environmental protection work furtherly. Taking the view of science and technology as the first productive force, to recognise the environment, manage the environment and construct the enuironment, highly concentrated on constructing Shanghai as an international city with harmonising human being and nature to develop science and technology works. Carrying out sustainable development strategy on environmental protection science and technology works to the whole process for deepening reform and promoting the development of environmental science and technology works. The author discussed on the major points of environmental science and technology works: priority development category, constructing decision ability on environmental administration, clean technology and production, production and consumption of sustainable energy resources, sustainable agricultural engineering, control of environmental pollution, protection of natural resources and utilisation of wastes, basic research on environmental category, study on international cooperation of environmental protection science and technology. Finally, put forward of targets and major tasks in 3 stages, i.e. 1993-1995, 1996-2000 and 2001-2010.
It indicates the principal environmental problems existing in the petrochemical industry during the Ninth Five-year Plan period ,puts forward some technologies which should be emphasized in their development in order to solve these problems as well as suggestions on the promotion of research and development of environmental protection science and technology.
Abstract This article summarizes the trends in global petroleum industry's science and technology development of corrosion and protection discussed in the 13th international corrosion congress. The congress confirms that some progress has been made in the aspect of theory, technology and management method, including considering corrosion problem through industry ecology, corrosion assessment method for assessing underground facility in three stage, progress achieved by cathode protection theory and practice,...
Abstract This article summarizes the trends in global petroleum industry's science and technology development of corrosion and protection discussed in the 13th international corrosion congress. The congress confirms that some progress has been made in the aspect of theory, technology and management method, including considering corrosion problem through industry ecology, corrosion assessment method for assessing underground facility in three stage, progress achieved by cathode protection theory and practice, and the development of corrosion layer technology etc. Combining with current condition of corrosion and protection technology development in domestic petroleum industry, it raises some knowledges for corrosion and protection science and technology development.
