It also covers all places, equipment or devices that may generate waste gas, waste water, noise, solid waste pollutants, Source strength accounting should cover all pollutants discharged from various sources, see Tables 1~4. 4.3 Determination of pollutants The determination of pollutants of various pollution sources in the fertilizer industry construction project shall include GB 8978, GB 9078, GB 13458, GB 14554, GB 15580, The pollutants in national and local emission standards such as GB 16297 and GB 26132 are shown in Tables 1 to 4. May be produced for the production process but the country Or pollutants not listed in the local pollutant discharge standards may be based on environmental quality standards, other industry standards, other national emission standards, Environmental quality improvement needs of local people's governments or ecological environment authorities, according to raw and auxiliary materials and fuel use, production process, production The analysis of products and by-products is determined. 4.4 Accounting method selection The methods for calculating the source of pollution of chemical fertilizer industry construction projects include material balance algorithm, analogy method, actual measurement method and pollution production coefficient method, etc. The method and selection order are shown in Tables 1~4. Source-based accounting methods should be selected in order of priority. If the priority method cannot be used, the reasons should be explained. Nucleus For the calculation method, see Chapter 5, Chapter 6, Chapter 7, Chapter 8, Chapter 9. 4 Existing engineering pollution sources are not manually monitored according to relevant management requirements, automatic monitoring equipment for installation of pollutants or automatic monitoring equipment is not In compliance with the regulations, in the process of environmental impact assessment management, it shall be rectified according to law and calculated according to the methods in Tables 1~4; In accordance with the relevant provisions of the discharge permit for accounting. Analogy method 2. Pollution coefficient method 3. Material balance algorithm Measured method a Nitrogen oxides are controlled by the manufacturer's manufacturer to control the concentration guarantee value or analogous equipment concentration values. b When the existing project pollution sources are strongly accounted for, when there are multiple pollution sources of the same type in the same enterprise, other pollution sources can be compared with the same type of pollution sources of the same type of pollution source. According to the accounting source. Exhaust gas When the pollution source of the new (reconstruction and expansion) construction project is normally discharged, the strong calculation of the source of nitrogen oxides generated during the combustion process of the organized exhaust gas is preferred to use the analogy method, followed by the pollution production coefficient. Method; the nitrogen oxides produced by the non-combustion process are preferentially based on the material balance algorithm, followed by the analogy method, the fouling coefficient method; particulate matter, fluoride The source strong accounting takes the analogy method first, followed by the material balance algorithm and the pollution yield coefficient method; the other pollutant source strong calculation takes the material balance algorithm first. Secondly, the analogy method and the pollution coefficient method are adopted. In the case of abnormal emissions, the material balance algorithm is preferred for the strong source of pollutants in the organized exhaust gas, followed by the analogy method and the pollution yield coefficient method. The strong source of particulate matter in unorganized exhaust gas is preferably analogous, followed by the material balance algorithm; other pollutant sources are prioritized. The material balance algorithm is used, followed by other feasible methods such as analogy or pollution coefficient method. Existing engineering pollution source In the normal discharge, the measured method of the organized exhaust gas source is measured by the actual method. In the case of abnormal emissions, the sulfur dioxide source in the organized exhaust gas is highly optimized. Firstly, the actual measurement method is adopted. When there is no actual measurement condition, the material balance algorithm or the pollution yield coefficient method is adopted; the nitrogen oxide source in the organized exhaust gas is strongly registered. The actual measurement method is adopted, and the analogy method or the pollution generation coefficient method is adopted when the actual measurement conditions are not available; the material balance algorithm and the pollution generation coefficient method are used for the calculation of other pollutant sources. When using the actual measurement method to calculate the actual discharge amount, the self-monitoring technical guide for the pollutant discharge unit of the fertilizer industry and the sewage discharge permit for the pollutant discharge unit Such as the use of automatic monitoring of pollution factors, only effective automatic monitoring data can be used for accounting; for the fertilizer industry The monitoring technical guide and the pollutant discharge permit of the pollutant discharge unit do not require the automatic monitoring of pollution factors, and the effective automatic monitoring data is preferred. Second, manual monitoring of data is used. When there are multiple sources of organized exhaust gas pollution of the same enterprise, other sources of pollution can be compared to the enterprise. The measured data of the same type of organized exhaust gas pollution source is strong. The strong accounting of volatile organic matter in unorganized exhaust pollutants is preferably measured by the actual method, followed by analogy or pollution coefficient method. Feasible methods; other pollutant sources are strongly accounted for by other methods such as analogy or pollution coefficient method. Waste water New (reconstruction, expansion) construction project pollution source The material balance algorithm is used to calculate the source of heavy metal pollutants in the wastewater discharge port of the workshop or production facility and the total discharge port of the wastewater; other pollutants The source-weighted calculation uses the material-weighting algorithm first, followed by the analogy method and the pollution-producing coefficient method. Existing engineering pollution source The measured source of the pollutants in the total discharge port of the wastewater, the discharge port of the workshop or the production facility (if required) is measured by the actual method. Measured by actual measurement In actual emissions, automatic monitoring is required for the self-monitoring technical guide of the pollutant discharge unit of the fertilizer industry and the pollutant discharge permit of the pollutant discharge unit. The pollution factor can only be counted by effective automatic monitoring data; the technical guide and row for self-monitoring of pollutant discharge units in the fertilizer industry Pollution units such as sewage units do not require the use of automatic monitoring of pollution factors, the use of automatic monitoring data is preferred, followed by manual monitoring of data. noise New (reconstruction, expansion) construction project pollution source The strong source of noise pollution is calculated by analogy. Existing engineering pollution source The strong source of noise pollution is preferred by the actual measurement method, followed by the analogy method. Solid Waste New (reconstruction, expansion) construction project pollution source The solid waste source strength calculation adopts the material balance algorithm first, followed by the analogy method and the pollution production coefficient method. Existing engineering pollution source The solid waste source strength calculation takes precedence over the actual measurement method, followed by the material balance algorithm. 4.5 Parameter selection The engineering design data may be taken from the strong accounting parameters of the new (reconstruction, expansion) construction equipment or facility pollution source. Existing engineering production equipment or The strong accounting parameters of the facility pollution sources can take effective monitoring data during the accounting period. 4.6 Source strength accounting Exhaust gas The source of the exhaust gas pollutants is calculated as the sum of the source and the source of the normal and abnormal conditions of all the pollution sources, and is calculated by the formula (1). 4.7 Summary of accounting results See Appendix A for the summary format of the strong source accounting results.
