Solution | Comprehensive Water Quality Monitoring Solution for the Petroleum and Petrochemical Industry

2024-12-26

01 REFERENCE STANDARDS

1. Comprehensive Sewage Discharge Standards (GB 8978-1996): Specifies monitoring indicators and standards for wastewater discharge points in petroleum refining industries.

2. Petroleum Refining Industry Pollutant Emission Standards (GB 31570-2015): Clarifies the maximum allowable concentrations of petroleum substances in wastewater, such as the maximum allowable concentration of oil in wastewater being 1mg/L under Class A standards, and 5mg/L under Class B standards in urban sewage treatment plants.

Key pollutant discharge units play a critical role in environmental protection. They are responsible for ensuring that their self-monitoring of pollutant discharge meets national regulations and monitoring specifications. These units must install automatic monitoring equipment, ensure the proper functioning of the equipment, and maintain original monitoring records.

1. Self-Monitoring Technical Guidelines for Pollutant Discharge Units - Petrochemical Industry (HJ974-2018): Requires automatic monitoring of flow, chemical oxygen demand (COD), and ammonia nitrogen at the wastewater discharge point in the petrochemical and synthetic resin industries (direct discharge).

2. Self-Monitoring Technical Guidelines for Pollutant Discharge Units - Onshore Oil and Gas Extraction Industry (HJ1248-2022): Requires automatic monitoring of flow, COD, and ammonia nitrogen at wastewater discharge points (both direct and indirect discharge).

3. Self-Monitoring Technical Guidelines for Pollutant Discharge Units - Oil Storage and Gas Stations (HJ1249-2022): Key pollutant discharge units must comply with regulations and use automatic monitoring equipment.

4. Self-Monitoring Technical Guidelines for Pollutant Discharge Units - Petroleum Refining Industry (HJ880-2017): Requires automatic monitoring of flow, COD, and ammonia nitrogen at wastewater discharge points (direct discharge).

02 MONITORING CONTENT EXTRACTION

Monitoring Points

Pollutant discharge units must set monitoring points at the following locations:

Wastewater discharge points (total discharge)
Wastewater discharge points from workshops or production facilities
Rainwater discharge points

Monitoring Parameters

Wastewater discharge points: Chemical oxygen demand (COD), ammonia nitrogen, flow rate
Rainwater discharge points: pH, chemical oxygen demand (COD), ammonia nitrogen, petroleum substances, suspended solids

03 INDUSTRY WASTEWATER MONITORING APPROACH

Based on the Treatment Process:

1. Raw Water Treatment Stage: The water quality status needs to be understood as it provides basic data for subsequent treatment processes, making it a critical stage for water quality monitoring.

2. Treatment Process Stage: Monitoring the changes in BOD and COD is essential to adjust the process in time and improve treatment efficiency, as well as optimize the treatment process and cost control.

3. Wastewater Discharge Stage: Based on the potential environmental risks posed by various pollutants, a range of comprehensive indicators such as COD and BOD is used to monitor whether the wastewater meets discharge standards.

Environmental Risk Prevention:

1. Rainwater Discharge Points: Considering the risk of oil leakage and other environmental risks in petroleum and petrochemical industries, rainwater runoff may carry pollutants into the rainwater discharge system, contaminating the external environment. Monitoring water quality at rainwater discharge points is necessary to prevent this.

2. Oil and Gas Field Storage Stations: During the storage and transportation of oil and gas, leakage of oil products may contaminate surrounding water bodies. Monitoring the water quality around storage stations can effectively control the extent and scope of pollution from an environmental risk prevention perspective.
