2. Type II water quality: The water quality is slightly polluted. After conventional purification treatment (such as flocculation, sedimentation, filtration, disinfection, etc.), the water quality is available to consumers.

 

3. Three types of water quality: Suitable for secondary protection areas, general fish protection areas, and swimming areas for centralized drinking water sources.

 

4. Four types of water quality: Applicable to general industrial protection areas and recreational water areas where the human body is not in direct contact.
