Abstract

The invention discloses a system for minimizing chemical oxygen demand (COD) discharge of a pesticide production waste liquid incinerator, comprising a field intelligent instrument connected with the pesticide production waste liquid incinerator, a DCS system and a host computer. The host computer comprises a standardized processing module for collecting training samples TX of key system variables from a database and the chemical oxygen demand data Y corresponding to the training samples TX and standardized processing the training samples TX, a support vector machine (SVM) module for soft-sensor modeling and a particle swarm algorithm module for solving the following minimum problem with the pgK obtained when iteration is ended being the operating variable with minimum chemical oxygen demand. The invention also discloses a method for minimizing the chemical oxygen demand (COD) discharge of the pesticide production waste liquid incinerator. The invention provides a system and a method for minimizing the chemical oxygen demand (COD) discharge of the pesticide production waste liquid incinerator, which can measure the COD online and effectively monitor whether the COD exceeds standard.

Description

technical field [0001] The invention relates to the field of pesticide production, in particular to a system and method for minimizing chemical oxygen demand (COD) discharge from a pesticide production waste liquid incinerator. Background technique [0002] With the rapid development of the pesticide industry, the environmental pollution of emissions has attracted great attention from governments and corresponding environmental protection departments. Researching and solving the standard discharge control and harmless minimization of pesticide organic waste liquid has not only become a difficulty and hot spot in scientific research in various countries, but also a scientific proposition that is urgently needed by the country related to the sustainable development of society. [0003] Incineration is currently the most effective, thorough and widely used method for dealing with pesticide residues and waste residues. The chemical oxygen demand of incinerated wastewater is the...
