Research on Advanced Available Techniques of Air pollution Prevention and Control in Building Ceramics Industry in China

Abstract

The flue gas emission of the building ceramics industry accounts for 85% of the whole ceramic industry in China, and it is the critical sector of air pollution control in the ceramic industry. The advanced available techniques (AAT) of air pollution prevention and control are of considerable significance to promote the upgrade of pollution prevention measures and technological progress. The paper studied and established the method of screening and evaluating the AAT for the prevention and control of air pollution in the building ceramics industry. Through collection and analysis of three normal pollutant emission concentrations of ten available techniques (AT), to select the AAT that meet at least one pollutant of all the plants was lower than 50% of the national standard emission concentration threshold in China. Based on the experience of the European Union and the comprehensive evaluation of industry associations, research institutions, and pollution control experts, five AAT were selected. The findings will provide an essential reference for the building ceramics industry to select advanced techniques, and provide significant technical support for the revision of the ceramic industrial pollutant emission standard for and selection of pollution prevention and control techniques (PPT and PCT) for pollutant discharge permission management.
