Problems solved by technology

[0010] The purpose of the present invention is to solve the problem that the existing shale gas wastewater treatment cannot realize the real-time adjustment of the influencing parameters as the process parameters change. This patent especially relates to the influence of the pollutant removal rate in the wastewater treatment process by the water temperature and water volume, which is different from the prior art. Compared with the fixed water intake indicators such as water temperature and water volume, they can be adjusted and controlled by feedback, and the subsequent feedback control of water quality can ensure that the water quality of the effluent is up to standard, so as to achieve economical and efficient wastewater treatment.

Embodiment Construction

[0052] A double loop feedback control system for water resources, the structure of the system is as follows Figure 6 As shown, including machines subject to dual-loop feedback control, a dual-loop temperature feedback controller and a dual-loop flow feedback controller are set behind the dual-loop feedback control machine to form an inner loop. A double-loop COD feedback controller and a double-loop BOD feedback controller are set outside to form an outer loop.

[0053] Because the dual-loop feedback controller adopts the same structure, so taking the dual-loop temperature feedback controller as an example, as Figure 7 As shown, the temperature sensor is set in the dual-loop temperature feedback controller, the temperature sensor is connected with the optimizer and the machine learning controller, the machine learning simulator is set after the optimizer, the machine learning controller is connected with the machine learning simulator and the valve, An error regulator is se...

Abstract

The invention discloses a water resource double-circulation feedback control system and method. The system comprises a double-circulation feedback control machine. The output end of the double-circulation feedback control machine is connected with the input end of a double-circulation temperature feedback controller and the input end of a double-circulation flow feedback controller. The output end of the double-circulation temperature feedback controller is connected with the input end of a double-circulation COD feedback controller and the input end of a double-circulation BOD feedback controller, and the output end of the double-circulation COD feedback controller and the output end of the double-circulation BOD feedback controller are connected with the input end of the double-circulation feedback control machine.

Description

technical field [0001] The invention belongs to the technical field of water circulation control, and in particular relates to a water circulation technology based on double-circulation feedback and temperature and flow regulation and capable of controlling COD and BOD indexes. Background technique [0002] With the continuous development of my country's economy, on the one hand, industrialization and infrastructure construction need to be deepened to meet people's growing living needs, but the extensive economic development in the past has caused great pressure on the ecological environment, especially the urban water environment; On the other hand, with the acceleration of urbanization and the improvement of people's living standards, the water consumption of urban life has also increased, and the resulting domestic sewage has not been effectively treated, such as clothing washing, catering, bathing, heating, etc. Toxic and harmful chemicals produced by household sewage, per...
