This paper discusses the controlling limit of the formulating emission standard of air pollutants for cement industry in Guangdong Province by analyzing the Emission Standard of Air Pollutants for Cement Industry(GB4915-2004) and the relevant standards abroad,and combining the results of researching and the presented technology of controlling dust,sulfur dioxide, nitrogen oxides,fluoride,etc.It is proposed that there is still some room,but not large,for the emission standards of local cement in Guangdong Province to be strict.Treating Pearl River Delta and other mountains areas differently,making a difference between the existing cement plants and the new-built ones by different time,guiding the cement industry to introduce new technologies and transfering to the base of clinker are still needed,and this will be a highlight in pollutant emission standards of cement industry in Guangdong Province to achieve the environmental planning requirements of the"Eleventh Five-Year".
