Introduction

Standard Background and Technological Evolution

As a key technical support document for the pollutant emission permit system for the non-ferrous metal industry, this standard is formulated based on the requirements of laws and regulations such as the Environmental Protection Law and the Air Pollution Prevention and Control Law. It is the first time that the pollutant emission permit management of the nickel smelting industry is systematically regulated, filling the gap in the nickel smelting pollution prevention and control technology system.

Core Management Requirements

Management Dimensions	Pyrometallurgical Process	Hydrometallurgical Process
Main Emission Outlets	Acid Tail Gas Chimney, Environmental Smoke Collection Chimney	Leaching Tank, Electrolytic Cell Exhaust Outlet
Characteristic Pollutants	SO₂, Nickel and Its Compounds, Arsenic and Its Compounds	Sulfuric Acid Mist, Heavy Metal Ions
Benchmark Exhaust Volume	12,000-18,000m³/tproduct	2m³/tproduct

Feasible technologies for pollution prevention and control

Waste gas treatment technology case

A nickel smelting enterprise adopts flash furnace with lime-gypsum desulfurization + electric bag composite dust removal, and the SO₂ emission concentration is stably controlled below 50mg/m³, which is 60% lower than the standard limit.

Comparison of wastewater treatment technologies

Wastewater treatment: Combination of sulfidation and lime neutralization process, heavy metal removal rate＞99.5%
Acidic wastewater: The biological agent treatment cost is 30% lower than that of traditional processes

Implementation suggestions

Establish a pollution source ledger for the entire process, focusing on recording the operating parameters of key equipment such as roasting furnaces and electrolyzers
Configure automatic monitoring equipment for particulate matter and SO₂, and keep data for ≥3 years
Carry out fugitive emission monitoring every quarter, focusing on the concentration of nickel and its compounds at the factory boundary
