How many kilometers is the pollution range of vanadium and titanium industry in Fiona Fang, and what is the pollution mode?

From the environmental point of view, the pollution modes of vanadium-titanium industry are mainly divided into four categories: atmospheric environmental impact, acoustic environmental impact, water environmental impact and solid waste impact.

Atmospheric environmental impact: The pollution sources that may have pollution impact on the surrounding atmospheric environment mainly include: dusty waste gas generated in the process of coal storage, transportation, crushing and crushing, flue gas generated in the process of coal charging and coke pushing, flue gas generated in the combustion of coke ovens and tubular furnaces using blast furnace gas and coke oven gas as fuel, and dusty waste gas generated in the process of coke dry quenching and coke screening. Dust-bearing waste gas produced in the process of fuel crushing, batching, flux, fuel, ore return and other materials mixing, flue gas from sintering section and cooling section of sintering machine, dust-bearing waste gas produced in the process of discharging from the tail of sintering machine, single-roller crushing and grading screening. Waste gas produced by charging system during ironmaking, dusty flue gas produced by blast furnace tapping yard, flue gas produced by pulverized coal preparation system, and purified blast furnace gas used as fuel combustion flue gas for hot blast stove. Waste gas generated by bulk material supply during steelmaking, hot metal pretreatment flue gas, converter secondary flue gas, refining flue gas outside the furnace and converter primary flue gas. Waste gas produced by finishing rolling in the process of steel rolling, and flue gas produced by burning purified gas in the heating furnace of steel rolling. Waste gas from vanadium product preparation, waste gas from ferrovanadium electric arc furnace, waste gas from vanadium trioxide drying and deamination, waste gas from vanadium pentoxide melting furnace, waste gas from rotary kiln, waste gas from vanadium trioxide deamination and waste gas from vanadium pentoxide deamination.

Acoustic environmental impact: The pollution sources that may have pollution impact on the surrounding acoustic environment mainly include equipment noise generated by pulverizers, vibrating screens, various pumps and fans.

Water environmental impact: The pollution sources that may pollute the water environment mainly include: production wastewater mainly includes sewage from clean circulating water system and phenol-cyanogen wastewater generated during coking production; The equipment produced in the process of sintering and ironmaking indirectly cools clean wastewater; Equipment in the steelmaking process cools the sewage from the purified water system; Continuous casting turbid circulating water system and primary flue gas purification turbid circulating water system sewage; And sewage from the indirect cooling system of steel rolling process equipment; Direct cooling water of high-pressure water dephosphorization station, roller table and other equipment, as well as wastewater generated in the production process of vanadium products. And domestic sewage generated by corresponding office and living facilities.

Impact of solid waste on environment: tar residue produced by gas purification system during coking, sludge produced by phenol-cyanogen wastewater treatment station, blast furnace slag, steel slag and scale, scale produced during steelmaking and rolling, vanadium product leaching residue, waste mineral oil, etc. And dust collected by various dust removal systems.

As for the environmental pollution scope of the vanadium-titanium project, it should be determined according to the production scale of the project, and we dare not talk nonsense.
