Scope

Scope: This document specifies the raw materials, finished product requirements, test methods, inspection rules, labeling, packaging, transportation, and storage requirements for salt sludge mixed stabilized materials. This document applies to the production and use of salt sludge mixed stabilized materials made primarily from salt sludge, and is only intended for the backfilling and utilization of Class II industrial land (including urban construction land for industrial use (M), logistics and warehousing land (W), and road and traffic facilities land (S)) where the groundwater salt content exceeds 1 g/L. Main technical content: - HJ 766: Determination of Metal Elements in Solid Waste by Inductively Coupled Plasma Mass Spectrometry - HJ 962: Determination of pH Value in Soil - HJ 1082: Determination of Hexavalent Chromium in Soil and Sediment - HJ 1091: Guidelines for Pollution Prevention and Control in the Recycling and Reuse of Solid Waste - "Notice on the Guidelines for Comprehensive Environmental Supervision of Solid Waste in Jiangsu Province" (Suehu Ban [2024] No. 16) 3. Terms and Definitions The following terms and definitions apply to this document. 3.1 Salt sludge: A solid material containing salts produced during the ion-membrane caustic soda process in the refining section of the chlor-alkali industry. 3.2 Salt sludge mixed stabilized materials: A material made by crushing and mixing salt sludge, silt, fly ash, and curing agents, which has certain compressive strength and can form a material that meets environmental standards and maintains long-term stability. 4. Raw material requirements 4.1 Before using salt sludge as a raw material, its source and other properties should be understood, and dangerous waste should be excluded through identification. The material should meet the requirements of environmental management and comprehensive utilization according to its properties. The pollutant control indicators and physical and c
