Embodiment 1

[0027] The evaluation object of this embodiment is the removal effect of nitrogen-containing organic matter in 6 urban domestic sewage treatment plants of actual scale in Jiangsu Province. The main processes of the 6 urban domestic sewage treatment plants evaluated are all anaerobic / anoxic / good Oxygen process, the sewage water samples used for evaluation are the influent water of 6 urban domestic sewage treatment plants, the effluent water of each unit of anaerobic / anoxic / aerobic process section, and the effluent water of sewage treatment plants. The daily treatment capacity of the six urban domestic sewage treatment plants is 43,800 cubic meters per day for sewage plant f1, 61,300 cubic meters per day for sewage plant f2, 3,200 cubic meters per day for sewage plant f3, and 16,600 cubic meters per day for sewage plant f4 cubic meters per day, sewage plant f5 is 6,800 cubic meters per day, and sewage plant f6 is 38,100 cubic meters per day. The evaluation steps for the removal ...

Embodiment 2

[0044] The difference with Example 1 is that the evaluation objects of this embodiment are 5 urban domestic sewage treatment plants of actual scale in the Pearl River Delta, and the main processes of the 5 urban domestic sewage treatment plants evaluated are all oxidation ditch processes, which are used to The sewage water samples evaluated were the influent of 5 urban domestic sewage treatment plants, the effluent of oxidation ditch process section, and the effluent of sewage treatment plants. The daily treatment capacity of the five urban domestic sewage treatment plants is 47,600 cubic meters per day for sewage plant f1, 44,000 cubic meters per day for sewage plant f2, 84,300 cubic meters per day for sewage plant f3, and 4,200 cubic meters per day for sewage plant f4 cubic meters per day, and sewage plant f5 is 26,300 cubic meters per day. Using high-resolution mass spectrometry and unsupervised feature dimensionality reduction analysis technology, the evaluation method est...

Embodiment 3

[0054] Different from Example 1, the evaluation objects of this embodiment are 7 industrial sewage treatment plants of actual scale in Jiangsu Province, and the main processes of the 7 industrial sewage treatment plants evaluated are all anoxic / aerobic processes. The sewage water samples for evaluation are the influent of 7 industrial sewage treatment plants, the effluent of each unit of anoxic / aerobic process section, and the effluent of sewage treatment plants. The daily treatment capacity of the 7 industrial sewage treatment plants is that the sewage plant f1 is 10,100 cubic meters per day, the sewage plant f2 is 44,400 cubic meters per day, the sewage plant f3 is 13,700 cubic meters per day, and the sewage plant f4 is 7,100 cubic meters m / day, sewage plant f5 is 14,600 cubic meters / day, sewage plant f6 is 1,600 cubic meters / day, and sewage plant f7 is 36,000 cubic meters / day. The evaluation of the removal effect of nitrogen-containing organic matter in 7 industrial sewage ...

Abstract

The invention discloses a sewage plant nitrogen-containing organic matter removal effect evaluation method based on high-resolution mass spectrometry, and belongs to the technical field of sewage treatment, the evaluation method comprises the following steps: (1) pretreating a sewage sample, and enriching nitrogen-containing organic matters in the sewage sample by using a solid phase extraction method; (2) analyzing and detecting nitrogen-containing organic matters in the sewage sample by adopting a Fourier transform ion cyclotron resonance mass spectrometer; (3) constructing a section data set of nitrogen-containing organic matter response peaks according to the nitrogen-containing organic matter spectrogram obtained in the step (2), and calculating and sequencing nitrogen-containing organic matter removal effects by adopting an unsupervised characteristic dimension reduction analysis technology; and (4) evaluating the removal effect of the nitrogen-containing organic matters in the sewage treatment plant according to the sequencing result. The evaluation method provided by the invention has the advantages of strong evaluation result integrity, high consistency and the like, and can be used for comprehensive comparison and evaluation of treatment effects of multiple sewage treatment plants.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and more specifically relates to a method for evaluating the removal effect of nitrogen-containing organic matter in sewage plants based on high-resolution mass spectrometry. Background technique [0002] Nitrogen-containing organic matter in sewage treatment plants refers to various organic compounds containing nitrogen functional groups, including dissolved nitrogen-containing organic matter, colloidal nitrogen-containing organic matter, and granular nitrogen-containing organic matter. In the process of sewage treatment, colloidal nitrogen-containing organic matter and particulate nitrogen-containing organic matter can be removed by hydrolysis, etc., or converted into dissolved nitrogen-containing organic matter, resulting in dissolved nitrogen-containing organic matter becoming the main nitrogen-containing organic matter in the sewage treatment process. Dissolved nitrogen-containing o...
