- Abstract:
- According to the Code for Urban Wastewater and Stormwater Engineering Planning (GB 50318-2017), the wastewater treatment plant (WWTP) should be set up with a health protection zone (HPZ) of not less than 150 m. However, the main treatment facilities of underground WWTP are located in sealed boxes, and the odorous pollutants generated during operation are not easy to spread, meaning that they have little impact on the surrounding environment, and the impact is much less after collection and treatment. Therefore, its setting requirements of HPZ are different from those of traditional WWTP. This paper summarized the setting requirements and existing problems of HPZ in WWTPs based on the development of relevant codes and standards, and introduced the derivation method of HPZ of WWTP combined with atmospheric environment requirements and environmental impact assessment. Based on the investigation of some similar engineering cases, the requirements for setting HPZ of underground WWTPs were summarized, which was generally not less than 100 m, and should be calculated from the diffusion boundary of fugitively discharge pollution sources. In addition, the specific methods for odor pollution control in underground WWTPs were introduced exemplified by engineering cases.
