Collection device for treating N2O on water level of treatment unit in sewage treatment plant and sampling method

Abstract

The invention discloses a collection device for treating N2O on a water level of a treatment unit in a sewage treatment plant and a sampling method, and belongs to the technical field of sewage sampling. The upper part of a collection flux box is of a hemispherical top type, and the lower part of the collection flux box is cylindrical; a baffle is arranged at the connecting part of the upper part and the lower part; the lower part of the baffle can be arranged in a floating plate in a sleeving manner; a small-size fan is arranged at the top of the baffle. According to the device, relevant sensors and pumps of a gas sampling system and a liquid sampling system are respectively integrated in two small-size equipment boxes, and the sealing property is high. The device is also provided with an in-box gas pressure meter, a gas thermometer and a liquid thermometer, so that relevant parameters can be measured in real time and are displayed in a text display of an on-line monitoring and control system; meanwhile, a control panel of the on-line monitoring and control system can be switched on to set the flow of a gas sampling pump and a liquid sampling pump. The device provided by the invention is simple in structure, high in integrality, convenient to carry and easy to operate, and can realize collection and measurement on release and dissolving N2O of the sewage treatment unit.

Description

technical field [0001] The invention relates to N 2 O and soluble N 2 O collection device and sampling method, suitable for monitoring sewage treatment plant N 2 O greenhouse gas emission, which belongs to the technical field of sewage sampling. Background technique [0002] N 2 O is a powerful greenhouse gas with a greenhouse effect about that of CO 2 310 times, and will cause strong damage to the ozone layer. In recent years, human activities have caused N 2 O Greenhouse gas emissions are increasing year by year, of which the N emitted during the denitrification process of sewage treatment plants 2 O deserves attention. So far, the world's response to N 2 A lot of experimental research work has been done on the source and sink of O, but due to the limitations of research methods and research conditions, the N in the sewage treatment system 2 There is still a lack of detailed and quantitative research on O emission. At present, for the N produced in the laboratory...

So far, the world's response to N 2 A lot of experimental research work has been done on the source and sink of O, but due to the limitations of research methods and research conditions, the N in the sewage treatment system 2 There is still a lack of detailed and quantitative research on the emission of O

At present, for the N produced in the laboratory and pilot reactor sewage treatment process 2 O collection and measurement have a certain research basis, but for the actual scale of N discharged from sewage treatment plants 2 O still lacks in-depth research
