2.Some new technological measures,such as new reactors,gel method to remove silicon,direct dissolve acid to recrystallizate and direct calcine from zirconyl chloride,were used to reform zirconium dioxide production process.As a result,the materials consumption and energy consumption were reduced and the wastewater discharge was decreased.Meanwhile the rubbish were recovered and utilized to prepare into a by-product as silica aerosol.The pollution prevention and control in production process were achieved.
3.Abstract: Some new technological measures,such as new reactors,gel method to remove silicon,direct dissolve acid to recrystallizate and direct calcine from zirconyl chloride,were used to reform zirconium dioxide production process.As a result,the materials consumption and energy consumption were reduced and the wastewater discharge was decreased.Meanwhile the rubbish were recovered and utilized to prepare into a by-product as silica aerosol.The pollution prevention and control in production process were achieved.
4.Although CR is replaced by competitive materials, the consumption for CR in the world still increases, and its prise also rises.
5.Article 18 New construction, construction renovation and expansion projects shall conduct environmental impact assessments with respect to analysis and assessment of use of raw materials, resource consumption, comprehensive utilization of resources, as well as generation of pollutants and their treatment; shall accord priority to adopting cleaner production technologies, processes and equipment, which maximize the resource utilization rate and generate few pollutants.
8.Through Literature materials,the author analysed the total of the college student?s sport consumption is increassing,and among those,the material objects consumption is chief,the trend of participating in consumption is upwards,the people of consumption in viewing and admiring is more and more,Furthermore the author proposed some appropriate tactics.
9.This paper is to develop a model on synthesis reaction of methanol using material and thermodynamics balance, and to utilize MATLAB to solve multielement nonlinear equation set on proposed model, so calculate balance composition of reactions, parameters of various materials, various process criteria such as methanol output and consumption according to given operation conditions, thereby can quantitatively analyze the effect of various operation conditions on process criteria, so that direct the actual chemical operation, thus assist to determine the optimal operating conditions of synthesis, consequently could forecast various criteria such as yield and consumption according to given conditions of feeds.
10.To use insulating materials in non-working section of chromeplating hanging fixture can prominently cut down the consumption of chromic acid and electric power, and also raise production efficiency.
