Soft sensing method of residual chlorine in water treatment system with structure of multiple pipelines corresponding to multiple clean-water reservoirs

Abstract

The invention discloses a soft sensing method of residual chlorine in a water treatment system with a structure of multiple pipelines corresponding to multiple clean-water reservoirs. The soft sensing method includes following steps: 1), obtaining flux of respective clean-water reservoir entrance according to flow distribution calculation formula of the structure of the multiple pipelines corresponding to the multiple clean-water reservoirs; 2), obtaining fall time tji from a j dosing point to an i clean-water reservoir entrance according to flux of clean-water reservoir entrances and flux of the pipelines; and 3), obtaining chlorine content Cli of the i clean-water reservoir entrance according to residual chlorine mixture formula. By the aid of the method, acquisition of effect-controlling core parameters of the residual chlorine at multiple clean-water reservoir entrances can be achieved under the condition of no residual chlorine detection devices, control precision is improved, the method plays an important role in stabilizing and improving water quality, and hardware input can be saved and the method has obvious economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of water treatment and information processing, and in particular relates to a residual chlorine soft measurement method of a water treatment system with a multi-pipeline corresponding to multi-clear water pool structure. Background technique [0002] At present, due to the process of industrialization and urbanization, the pollution of water source water quality is becoming more and more severe. However, the people's requirements for water quality are greatly increasing, and they are no longer satisfied with low-quality tap water. Consumption and stable water supply require water treatment companies to continuously improve automation and detection technology. [0003] However, my country's waterworks are basically established after the founding of the People's Republic of China, the equipment is relatively old, and there are not many testing instruments, or because the waterworks are small in scale, they can...
