(2) measures to protect the ecological environment

1. Prevention and control of air pollution. Strictly implement the requirements of the opinions on promoting the implementation of Ultra-low Emission in the Iron and Steel Industry (Huanwei (2019) 35) and the air pollution prevention and control measures put forward in the report, and build high-efficiency desulphurization, denitrification and dust removal facilities for Synchronize. The treatment capacity and efficiency of each treatment facility should meet the needs, fine desulphurization of blast furnace gas should be carried out, and sintering machine flue gas circulation should be carried out in combination with layout and process optimization. No flue gas bypass shall be set up, and the height of the exhaust cylinder shall meet the requirements of environmental assessment and comply with the relevant regulations; comprehensively strengthen the unorganized emission control of material storage, transportation and production process, and adopt effective control measures such as sealing and sealing, so as to effectively improve the waste gas collection rate, there shall be no visible smoke and dust escape from the dust production point and workshop. To implement the requirements for clean transportation of bulk materials and products, bulk or powdered materials such as ores should be airtight transported by means of tubular belt conveyors, or closed transportation by means of belt corridors; if automobile transportation is really needed, all new energy vehicles or vehicles that meet the sixth national emission standards should be adopted, closed carriages or covers should be used for bulk or powdered materials, and dust suppression measures such as humidification should be taken when loading and unloading vehicles.

Organized measures for the prevention and control of waste gas pollution:

(1) Raw material yard process: unloading waste gas, receiving waste gas, mixing waste gas and transporting dust removal waste gas are collected by gas collecting cover and then treated by bag dust collector with film-coated filter material.

(2) Sintering process: the flue gas of the sintering machine head is treated by "double-chamber four-electric field Static precipitator + circulating fluidized bed flue gas desulfurization + cloth bag dedusting (coated filter material) + SCR denitrification", and the sintering mixed waste gas is treated by high efficiency wet dust collector. Fuel flux crushing and screening waste gas, sintering batching waste gas, sintering machine tail gas, whole grain screening waste gas, sintering product transfer waste gas, finished product ore trough waste gas and so on are all treated by film-coated filter bag dust collector.

(3) ironmaking process: blast furnace coke trough material distribution, iron field, furnace top material distribution, pulverized coal preparation and injection are all treated by film-coated filter bag dust collector; the waste gas of iron casting machine is removed by bag dust collector; blast furnace gas is refined desulphurized by "gravity dust collector + bag dust collector + blast furnace gas hydrolysis + alkali injection desulphurization"; blast furnace hot blast furnace adopts purified blast furnace gas as fuel + low nitrogen combustion process.

(4) steelmaking and continuous casting process: the primary flue gas of converter and dephosphorization pretreatment furnace is treated by LT dry dedusting; the secondary flue gas of converter, dephosphorization and desulphurization pretreatment furnace, converter tertiary flue gas, alloy melting furnace, refining furnace feeding flue gas, flame cutting machine flue gas and grinding machine flue gas are all treated by coated filter bag dust collector.

General industrial solid waste should be fully utilized. General industrial solid wastes such as iron oxide scale, slag flushing pool sludge, central wastewater station sludge and dust removal from various processes are returned to the sintering system or partially sold, scrap and casting residue are reused in steelmaking workshop, steel slag, desulphurization slag, blast furnace slag and waste refractories are used for export and comprehensive utilization. The waste carbon-based desulfurizer for fine desulfurization of blast furnace gas, the waste manganese catalyst for denitrification, the waste ion exchange resin and the abolition of dust cloth bags (except for hazardous characteristics identification) are recycled by manufacturers. After the domestic waste is collected, it will be handed over to the local sanitation department for disposal.

Waste oil buckets, waste engine oil and hazardous wastes such as converter, dephosphorization pre-treatment furnace and AOD furnace shall be collected and stored in a standardized manner, and qualified units shall be entrusted to dispose of or recycle them. Light dust removal ash from sintering machine head, blast furnace gas ash and its abolishing dust cloth bag, as well as converter, dephosphorization pre-treatment furnace and AOD furnace waste dust removal cloth bag should be identified, and should be disposed according to the standard of identification results, and hazardous waste management should be carried out before identification.

5. Implement measures to prevent and control noise pollution. The layout of high noise equipment should be optimized, low noise equipment should be given priority, and measures such as noise elimination, sound insulation and shock reduction should be taken to reduce noise. The noise at the factory boundary must meet the requirements of the "Environmental noise Emission Standard for Industrial Enterprises" (GB12348-2008), so as to ensure that the environmental quality of environmental sensitive points is up to the standard and prevent noise from disturbing people.

6. Environmental risk prevention. Strengthen the essential safety management of the project, strengthen environmental risk prevention and emergency measures. Automatic gas leakage detection and alarm devices are set up in the storage, transportation and use areas of gas-related risky substances such as coal gas, sulfuric acid, hydrochloric acid, sodium hypochlorite and natural gas to ensure timely detection and effective disposal of toxic and harmful gas leakage accidents; set up a sufficient volume of self-flow environmental accident emergency pool, equipped with perfect accident wastewater interception and diversion facilities to ensure the effective transportation and recovery of accident waste water; Chemical tank area cofferdams, rain (sewage) pipe ditches, initial Rain Water collection pools, Rain Water discharge outlets and other environmental risk facilities and prevention and control links, such as production wastewater treatment facilities, shall be equipped with switching valves and connected with the accident emergency pool to ensure that the waste water from the emergency disposal of the accident is not discharged.
