Introduction

Analysis of standard technical framework

This standard innovatively proposes two technical paths: sintering-blast furnace metallurgy method and roasting and leaching method, covering the resource recovery treatment of electroplating sludge with chromium content ≥ 0.4%. Core indicator comparison:

Technical parameters	Sintering-blast furnace metallurgy method	Roasting and leaching method
Applicable chromium content	≥0.4%	Full content range
End products	Chromium-containing pig iron/alloy	Sodium dichromate
Core temperature range	1700-2000℃	1150-1200℃
Resource utilization rate	Comprehensive recovery rate of iron and chromium>92%	Chromium conversion rate>85%

Detailed explanation of sintering - blast furnace metallurgy technology

This technology achieves deep reduction of heavy metals through three-stage temperature control:

Drying process: 700-850℃ to evaporate water
Sintering process: 1350℃ to form sintered ore
Blast furnace smelting: 2000℃ to separate iron and chromium

Key control points: pellet size 8-12mm, bursting temperature ≥380℃, basicity ratio 1.2-1.8.

Technological innovation of roasting and leaching method

Using chromite co-treatment technology, electroplating sludge and chromite are mixed and roasted in a ratio of (0-15):100. Typical case:

A company adopts a rotary kiln-wet grinding combined process to increase the trivalent chromium oxidation efficiency by 40%, and all the mirabilite waste residue is used for sodium sulfide production, achieving zero wastewater discharge.

Key points for environmental protection compliance

According to the requirements of GB18597, the following must be met:

Dust emission concentration ≤30mg/m³
Total chromium content in wastewater ≤1.5mg/L
Establish a full life cycle ledger (storage period ≥5 years)

Implementation suggestions

Enterprises should consider the following when choosing a technical route:

For chromium content <1%, roasting method is preferred
Blast furnace method that can be integrated with steel production capacity
Establish an online monitoring system to monitor dioxin emissions
