Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings.

[0037] Such as figure 1 As shown, an online detection system for available chlorine in a water disinfection process includes a plunger pump 13 and a multi-channel exhaust valve. The multi-channel exhaust valve has a central channel and several sub-channels, and several sub-channels are connected to the central channel. Connected, electromagnetic valves are respectively arranged on the pipelines of the sub-channels; the plunger pump 13 is connected with the central channel through pipelines, and six sub-channels are respectively connected to water samples, dilution devices, cleaning channels through pipelines in the several sub-channels. Liquid, detection device, waste liquid tank and atmosphere, one sub-channel is connected to pure water through pipelines, pure water and plunger pump 13 are connected through pipelines, and the remaining two sub-channels are respectivel...

Abstract

The invention discloses an online detection system and method for available chlorine in a water quality disinfection process. The method comprises the following steps: 1, diluting a high-concentrationwater sample (if the concentration is low, skipping this step); 2, quantitatively conveying the diluted water sample into a reaction tank, and detecting the light intensity penetrating through the water sample; 3, quantitatively conveying a detection reagent into the reaction tank, performing blowing, bubbling and stirring, standing the water sample for 5 minutes, and detecting the light intensity penetrating through the mixed solution; and 4, calculating the absorbance according to the light intensity values before and after dosing, and calculating the effective chlorine content according tothe linear curve of the absorbance and the effective chlorine content. Compared with a traditional titration method, the online detection system and method for available chlorine provided by the invention have the advantages of rapidness, simplicity, convenience, short measurement period, high sensitivity, less reagent consumption, online detection and the like.

Description

technical field [0001] The invention relates to an online detection system and method for available chlorine in a water quality disinfection process, belonging to the technical field of available chlorine testing. Background technique [0002] Chlorine-containing preparations are the earliest chemical disinfectants used for drinking water disinfection, and they are also the most widely used drinking water disinfectants. The concept of available chlorine in chlorine-containing preparations as drinking water disinfectants is based on chlorine gas, which is a method to characterize the oxidation capacity of chlorine-containing disinfectants. Specifically, it refers to the interaction between a certain amount of chlorine-containing disinfectants and acids. Its oxidizing ability is equivalent to the oxidizing ability of how much weight chlorine. The higher the chlorine content of available chlorine in the disinfectant, the stronger the disinfection ability, and the more effectiv...
