2 Terms
2.0.1 Sound screen
The facility set between the sound source and the receiving terminal to weaken the sound wave and reduce the noise impact at receiving terminal.
2.0.2 Background concentration
The background concentration is also known as environmental background concentration, which means the concentration of various pollutants in the environment before the environment is directly polluted by the project.
2.0.3 Pollution coefficient
The ratio of the frequency in a certain wind direction to the average wind speed in this direction.
2.0.4 Sound absorption
Sound absorption refers to the process that the sound energy is reduced or changed into other energy when the sound wave passes through a certain kind of medium or radiates onto a certain dielectric surface.
2.0.5 Sound insulation
Sound insulation refers to the measure taken to consume the energy of sound wave by using endergonic materials when the sound wave propagates in the air so as to make the sound energy be blocked during the propagation route and not pass through directly.
2.0.6 Noise elimination
Noise elimination refers to the process that various silencers are used to weaken or eliminate the sound generated from the sound source.
3 Basic Requirement

3.0.2 The design of environmental protection engineering of cement plant shall meet the requirements of cleaner production, recycling economy, and energy conservation and emission reduction, the pollution control shall adopt reliable and advanced production process and technical equipments in combination with the innovation of production process.
3.0.3 The design of environmental protection engineering of cement plant shall be combined with the comprehensive resource utilization, energy conservation and water conservation, shall positively popularize the utilization of alternative raw materials and fuel, and shall popularize the utilization technologies of such resources as waste heat.
3.0.4 The waste heat utilization scheme of cement plant shall be in accordance with the local conditions. The matching low temperature waste heat power generation project may constructed or the construction land may be reserved according to the conditions of water, heat and electricity resources in the plant building area, or the waste heat of production may be transformed into heat for living or other utilization measures may be taken.
3.0.5 When the cement plant disposes or cooperates to dispose the hazardous wastes, industrial wastes and other wastes, the safe and effective disposal scheme shall be taken. The content of toxic and hazardous substances in products and the concentration of toxic and hazardous substances in emissions shall meet the relevant provisions of corresponding current national standards for the products and pollutant emission.
3.0.6 The environmental protection facilities shall include the following contents:
1 Dedusting facilities;
2 Flue gas and waste gas purification facilities;
3 Chimney (or exhaust funnel);
