T/CPCIF 0343-2024 Soil Microbial Leaching Technique Specification for Chromium Contamination

Scope

Scope: This document specifies the technical requirements for microbial leaching of chromium-contaminated soil, including pollutants and pollution loads, general requirements, process design, main process equipment and materials, testing and process control, construction, and operation and maintenance. This document applies to the engineering design, construction, and operation management of ex situ remediation of chromium-contaminated soil using microbial leaching. **Main Technical Content**: 5.1 General Requirements 5.1.1 The design, construction, and operation of microbial leaching projects for chromium-contaminated soil shall comply with the relevant provisions of current national laws, regulations, and standards. 5.1.2 The remediation plan shall be formulated based on the investigation report on soil pollution status, the hydrological and geological survey report of the site, and the risk assessment report of soil pollution. 5.1.3 The remediation target values shall be determined based on the site investigation, risk assessment, remediation and risk control plans, and the requirements for soil environmental function classification, and shall serve as the basis for acceptance of the remediation of chromium-contaminated soil. 5.1.4 The microorganisms used shall undergo environmental safety evaluation in accordance with HJ/T 415. 5.1.5 The materials used in the remediation process shall be safe and environmentally friendly and shall not react with the microbial solution. 5.1.6 Secondary pollution control measures shall be taken during the microbial leaching of chromium-contaminated soil to collect and properly handle wastewater, waste gas, and solid waste generated during the construction and leaching process. When discharging wastewater and waste gas into the environment, they shall comply with the requirements of GB 8978, GB 16297, and local pollutant discharge standards; noise control shall comply with the requirements of GB 12348. 5.1.7 Aft
