- Abstract:
- Underground wastewater treatment plants have the advantages of small footprint, environmental friendliness, less secondary pollution, and no influence on the value of surrounding land. But it also has disadvantages such as high investment of construction, high energy consumption of operation, high cost of maintenance and management. In addition， the underground wastewater treatment plants have the following problems: (i) Ventilation and smoke exhaust conditions are poor. (ii) Facilities are susceptible to humidity and corrosion. (iii) Equipment maintenance is not convenient. (iv) Improper design and construction can easily lead to serious dangers such as floods, poisoning, explosions and difficulties in escape. In January 2021, the China Engineering Construction Standardization Association has issued the Technical Specification for Urban Underground Wastewater Treatment Plant (T/CECS 729-2020). The design, construction and operation system of the underground WWTP was standardized. The establishment background, ideas and contents of the regulations are mainly interpreted, which is helpful for engineers and technicians to deeply understand the key technical points of underground WWTP design, promoting profession development and technological progress.
