《城镇地下式污水处理厂技术规程》要点简析
- Title:
- Synopsis of Key Points for Technical Specification for Urban Underground Wastewater Treatment Plant
- 摘要:
- 地下式污水处理厂具有占地面积小、环境友好、二次污染少、不影响周边土地价值等优点，同时也存在建设投资高、运行能耗高、维护管理成本高等问题。地下式污水处理厂通风及排烟条件差、易受潮腐蚀，设备检修不便，设计和建设不当易发生受淹、中毒、燃爆以及逃生困难等重大危害。2021年1月，中国工程建设标准化协会发布实施《城镇地下式污水处理厂技术规程》（T/CECS 729—2020），以规范我国地下式污水厂的设计、建设和运维管理。从编制背景、编制思路、编制内容三方面对该规程进行重点解读，以利于工程技术人员深入理解地下式污水厂设计的关键技术要点，促进行业发展和技术进步。
- 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.
