Embodiment Construction

[0018] The purpose of the present invention is to establish a set of an oxidation ditch intelligent control system based on influent changes to realize efficient and stable synchronous nitrification and denitrification processes in the oxidation ditch according to the water quality characteristics and daily variation rules of sewage water quality in different cities in my country.

[0019] At present, the sewage treatment plants in operation are basically equipped with a relatively complete PLC control system. The system can realize the monitoring data collection of the online monitoring equipment of each construction unit in the process flow of the sewage treatment plant, and the implementation of the control strategies of different control units. It mainly includes pretreatment control, aeration and push flow control, return sludge and sludge discharge control, and sludge treatment unit control, etc. If an auxiliary chemical phosphorus removal unit is added, an automatic contr...

Abstract

The invention discloses an oxidation channel intelligent control system, which bases on the digging water change and belongs to the water pollution controlling technical field in the environmental protection. The system consists of a digging-water monitoring system, an operation decision support system, a control system and a process on-line monitoring system. According to the dynamic change of the digging water, the system timely monitors the change and collects dynamic data information into the decision support system. Through the simulation analysis of the decision support system, corresponding suitable operation conditions and control strategies are generated. The running state of the system is determined. Then, the process operation is regulated through the controlling system. And system operation parameters are monitored by on-line monitoring equipments and are fed back to the control system and the operation decision system. The feedback verification and the decision correctionare implemented on the system running strategies to guarantee the successful application of the simultaneous nitrification and denitrification of the oxidation channel process. Both the application of the advanced technology in the sewage treatment process is guaranteed and great energy saving and consumption reduction are realized. The larger treatment potentiality of water plants is exploited.

Description

technical field [0001] The invention belongs to the technical field of water pollution control in environmental protection. In particular, it involves the upgrade and transformation of the existing oxidation ditch process, optimizes the process operation control strategy, improves the performance of the control system and optimizes the design of the new oxidation ditch process, improves the sewage treatment effect and operational stability of the oxidation ditch process, and at the same time can achieve substantial energy savings. An intelligent control system of oxidation ditch based on the change of influent water consumption. Background technique [0002] At present, the problem of environmental pollution in my country is serious, and the problem of eutrophication of water bodies is becoming more and more serious. At the same time, with the rapid development of my country's economy, the demand for energy is also increasing day by day. Key factor. Urban sewage treatment i...
