Embodiment 1

[0055] In view of the above-mentioned defects, this embodiment provides a sewage treatment data traceability system. On the basis of the existing sewage treatment SCADA system, a process control subsystem and an OPC interface system are added, wherein the process control subsystem is used to connect The processing unit of the system, the OPC interface system is used to integrate the original SCADA system and the newly added process control subsystem; in addition, a business data recording subsystem is added to integrate maintenance personnel's "manual" operation, instrumentation and equipment failure repair Information and other business data such as maintenance information (such as personnel and expenses) closely related to the sewage treatment process. In this way, the process data and business data involved in the sewage process are integrated, and various historical states and behaviors of sewage treatment are systematically and comprehensively recorded, so as to realize th...

Embodiment 2

[0119] Image 6 A flowchart showing a sewage treatment data backtracking method according to an embodiment of the present application.

[0120] refer to Image 6 , in step S10, collect real-time operating data of the first sewage treatment unit.

[0121] The sewage treatment system may include a first sewage treatment unit and a second sewage treatment unit; preferably, the real-time operation data of the first sewage treatment unit is collected through a SCADA data acquisition subsystem.

[0122] For example, the SCADA data acquisition subsystem can be directly connected to various sensors and instruments at the bottom of the process flow of the first sewage treatment unit, or can be indirectly connected to various sensors and instruments through PLC to collect real-time data detected by sensors and instruments. Operating data.

[0123] In step S20, real-time operation data of the second sewage treatment unit is collected.

[0124] Preferably, the real-time operation data...

Abstract

The invention discloses a sewage treatment data backtracking method and system. The sewage treatment data backtracking method comprises the steps that real-time operating data of a first sewage treatment unit is collected; real-time operating data of a second sewage treatment unit is collected; the real-time operating data of the first sewage treatment unit and the real-time operating data of thesecond sewage treatment unit are merged to serve as process data, and the process data is stored into a process database; service data of the first sewage treatment unit and the second sewage treatment unit is recorded, and the service data is stored into a service database; and the process data and the service data are processed, so that backtracking of the process data and the service data is realized. Through the sewage treatment data backtracking method and system, integration of the process data and the service data can be realized, and effective backtracking is realized on the data in the whole sewage treatment process.

Description

technical field [0001] The present application generally relates to the technical field of sewage treatment, and more specifically, relates to a sewage treatment data backtracking method and system. Background technique [0002] With the development of industry and the increase of population, the problem of water pollution has become increasingly prominent, and the sewage treatment industry has developed rapidly. At present, the automatic control of most sewage treatment plants has covered most of the treatment processes in the whole process of influent sedimentation, biochemical treatment, chemical dosing and disinfection, and sludge dehydration, and can be mainly divided into three levels. The uppermost layer mostly adopts data acquisition and supervisory control (SCADA) system, which is placed in the central control room to monitor the operation of the instruments and equipment in the whole plant. The middle layer uses a programmable logic controller (PLC) to complete th...
