How to establish a pollutant investigation mechanism in chemical plants?
Establishing a pollution investigation mechanism for chemical plants requires institutionalization, normalization, and technologization as the core, through clarifying the responsibility system, standardizing processes, and introducing intelligent means, to achieve a transformation from passive response to active prevention and control.
The investigation of pollutants in chemical enterprises is not a one-time task, but should establish a long-term management mechanism that is executable, traceable, and optimizable. This mechanism needs to cover four dimensions: organizational support, institutional design, technical support, and continuous improvement, to ensure controllable environmental risks and sustainable compliant operations.
1、 Establish a sound organizational structure and responsibility system
Clarifying who will investigate and who is responsible is the prerequisite for the implementation of the mechanism:
Establish an environmental hazard investigation leading group led by the main person in charge of the enterprise, to coordinate and coordinate departments such as environmental protection, production, and equipment
As the main body of daily execution, the safety and environmental department shall establish dedicated environmental inspectors to implement the responsibility of "grid based" management
Implement a hierarchical responsibility system: daily team inspections → weekly workshop inspections → monthly comprehensive company inspections → quarterly expert consultations
According to the requirements of the "Guidelines for the Investigation of Soil Pollution Hazards in Key Supervision Units", the investigation responsibilities will be included in the job responsibility system and performance evaluation.
2、 Develop standardized inspection system and process
Unified standards are necessary to ensure the quality and comparability of inspections
Develop the 'Guidelines for Pollutant Screening Operations'
Clearly define the scope of investigation (such as tank storage areas, sewage tanks, hazardous waste warehouses), frequency (daily/special/seasonal), methods (visual+instrument+ledger), and record format.
Establish a closed-loop management mechanism for "three orders"
Problem List: Record the discovered issues such as leakage, corrosion, and missing identification
Responsibility List: Clearly identify the person responsible for rectification and the deadline for completion
Cancellation list: Only after rectification and retesting to meet the standards can it be closed, forming a closed loop
Implement a dynamic update mechanism
Timely update the list of key pollutants and high-risk locations based on process changes, new construction and expansion projects, or regulatory requirements.
3、 Integrating technological means to enhance investigation efficiency
Upgrade from "human defense first" to "technical defense priority" to enhance the ability to identify problems:
Promote LDAR (Leak Detection and Repair) technology
Conduct periodic VOCs testing on controlled sealing points such as valves and flanges, establish electronic ledgers, and achieve digital management

Deploy online monitoring system
Install automatic monitoring equipment at key locations such as wastewater discharge outlets, exhaust chimneys, and groundwater monitoring wells to monitor real-time changes in pollutant concentrations.
Application intelligent analysis platform
By utilizing big data and machine learning technologies, we can construct a "emission pattern portrait" of enterprises, identify abnormal emission behaviors, and achieve accurate off-site warning.
Lanzhou Petrochemical has achieved real-time locking of exhaust gas components through on-site analysis using a portable GC-MS analyzer, greatly improving the efficiency of investigation.
