Introduction
1. Background and significance of standard formulation
GB/T 39793.2—2020 "Basic Methods of Technical Guidelines for Ecological and Environmental Damage Identification and Assessment Part 2: Virtual Treatment Cost Method for Water Pollution" was formulated to implement the "Civil Code of the People's Republic of China", "Environmental Protection Law of the People's Republic of China" and other laws and regulations, and to standardize the identification and assessment of surface water environmental pollution damage.
2. Comparative analysis of standard frameworks
| Standard Dimensions | Scope of Application | Key Terms | Assessment Methods |
|---|---|---|---|
| Virtual Treatment Cost Method (VAC) | Applicable to situations where the facts of wastewater or solid waste discharge are clear, but the scope and extent of damage are unclear. | - Unit governance cost - Emission quantity - Adjustment coefficient | D = E × C × γ |
| Actual governance cost method (ACC) | Applicable to situations where the actual governance costs are clear and can be directly calculated. | - Governance facility investment - Operation cost - Waste disposal fee | Direct calculation based on actual data |
| Market value method (MVC) | Applicable to situations where ecological and environmental service functions can be marketed. | - Ecological value of water bodies - Scope of pollution impact | Indirect assessment based on market prices |
3. Standard implementation procedures
Case study: Virtual governance cost method assessment of wastewater discharge incident in an industrial park
- Applicability analysis:Confirm that the fact of wastewater discharge is clear, but the scope and extent of damage are unclear.
- Determine unit governance cost:Obtain the average governance cost of the same industry through actual investigation method.
- Verify the discharge quantity:Calculate the total amount of wastewater by combining on-site measurement and material balance method.
- Determine the adjustment coefficient:According to the water body function (drinking water source) and the hazard of pollutants (category 1), take the maximum hazard coefficient and environmental function coefficient.
- Calculate the amount of damage:Based on the formula D = E × C × γ, the specific amount of damage is obtained.
4. Implementation suggestions and precautions
In practical applications, the following points should be focused on:
- Data accuracy:Ensure that the calculation basis of emission quantity, unit governance cost and adjustment coefficient is sufficient and reliable.
- Method applicability:Choose the appropriate method according to the specific situation, and pay attention to the connection with other assessment methods.
- Environmental function zoning:According to the functions of different water bodies (such as drinking water sources, fishery water, etc.), reasonably select environmental function coefficients.
- Policy connection:During the implementation process, ensure consistency with relevant laws, regulations and policy documents.
