4.1 Accounting procedures The strong source accounting procedures include pollution source identification and pollutant determination, accounting methods and parameter selection, source strength accounting, 3 Accounting results, etc. See HJ 884 for details. Identification of pollution sources and determination of pollutants should also comply with HJ 2.1, HJ 2.2, HJ/T 2.3, HJ 2.4, HJ 708 and other technical guidelines and related emission standards. The discharge of pollutants should include normal and abnormal conditions (including sintering machine (pellet equipment) start-up, exhaust gas) Governance facility failure) Pollutant emissions in both cases. 4.2 Principles of accounting methods 4.2.1 General requirements Strong source accounting methods include material balance algorithm, analogy method, pollution production coefficient method, sewage coefficient method and actual measurement method, etc. The methods for calculating the source of each pollution source are selected in the order specified in Appendix A. 4.2.2 Exhaust gas a) New (reconstruction, expansion) construction project pollution source Particulate matter is preferentially accounted for by the analogy method, followed by the blowdown coefficient method. Sulfur dioxide and fluoride are preferentially calculated using the material balance algorithm, followed by analogy. Nitrogen oxides are accounted for using an analogy method. The other feature factor source strong accounting method selects the priority order as the material balance algorithm and the analogy method. The unorganized source of exhaust gas is accounted for by analogy or other feasible methods. b) Existing engineering pollution sources The organized source strength of the exhaust gas is preferentially calculated by the actual measurement method, and the second particle is calculated by the analogy method, sulfur dioxide and fluorine.
