水泥工业的环境负荷及控制途径

水泥生产过程中资源和能源的消耗、污染物的排放等问题是关系到水泥工业可持续发展的重要问题。针对这些问题进行了宏观分析和研究．并探讨了低环境负荷型水泥的生产技术。研究表明：水泥工业对环境负荷影响最大的因素一是燃料、电力、石灰石等能源、资源负荷；一是粉尘，CO2，SO2，NOx排放及噪声污染负荷。在预分解窑工艺条件下，要实现生产低环境负荷的熟料，解决我国水泥工业的环境负荷问题，可以从优化配料方案并最大限度地利用工业废弃渣，研发高效燃烧器，研制高活性功能胶凝材料以及研发高效益低能耗粉磨系统等方面进行技术探讨。

Study on environmental load and the control approach in cement industry

The consumption of material source and energy source and the emission of pollutant etc.in cement production process is an important problem about cement industry sustainable development. Aiming at these problem, macro analysis and research are carried out and the technology of producting low-environmental-load and high-performance cement is discussed. The research shows that the most effect factor of cement industry to environmental load is enery source and material source such as fuel,power and limestone etc. and emission of dust,CO2, SO2,and NOx and the noise pollution. In condition of precalciner kiln technology, to realize low-environmental-load clinker and to solve environmental load problem of China cement industry, it can be discussed by aspects as optimize proportion to utilization industry waste mostly, develop high-efficency burner and high-activity functional cementing material and high-benefit low-energy-consumption grinding system etc.
