摘要
介绍了国内典型的A2/C氧化沟、奥贝尔氧化沟和DE氧化沟的工作原理及其特点,总结各自的结构及工艺对脱氮除磷效果的影响。最后指出,生物除磷脱氮技术的发展和提高氧化沟中微生物活性是氧化沟未来发展的重要推动力;今后要进一步提高研究氧化沟设备性能和监控技术,减少占地面积和工程造价。
An introduction is given to the working principle and characteristics of some typical oxidation ditches, such as the A^2/C oxidation ditch, Orbal oxidation ditch, and DE oxidation ditch, and the effects of their structures and techniques on nitrogen and phosphor removal are analyzed. It is pointed out that the development of the nitrogen and phosphor removal technique and improvement of the microbial activity in oxidation ditches are the main impetuses to the further development of oxidation ditches, and that it is necessary to improve the performance of devices of oxidation ditches and their monitoring technique, so that the occupied area and engineering cost can be reduced.
