Abstract

The invention relates to a water quality on-line permanganate index monitor, comprising a chassis, wherein a touch display is mounted on the chassis; an industrial control machine, a digestion unit, atitration unit, a sampling unit, a liquid adding unit and a drainage storage unit are mounted in the chassis; the digestion unit, the titration unit, the sampling unit, the liquid adding unit and thedrainage storage unit are respectively connected to the industrial control machine; a sulfuric acid quantification bottle, a sodium oxalate quantification bottle, a pure water quantification bottle and a water sample quantification bottle are all mounted with capacitive sensors. The monitor can achieve independent injection and drainage, and a semi-closed digestion pool can perform high temperature digestion of a sample to resolve metal ions; the solution can be mixed thoroughly by means of a stirring motor, and electrodes can be well cleaned. The invention also relates to a detecting methodof the water quality on-line permanganate index monitor, which can achieve continuous monitoring of an on-line water quality permanganate index to reflect the change of the water quality permanganateindex at any time, thereby reducing the workload of monitoring personnel.

Description

technical field [0001] The invention relates to a water quality on-line permanganate index monitor and a detection method, belonging to the technical field of water quality detection. Background technique [0002] Permanganate index refers to the amount of oxidant consumed when treating water samples with potassium permanganate as oxidant in acidic or alkaline medium, and is mainly used to control the quality of drinking water and surface water. [0003] In the prior art, the detection of water quality permanganate index is usually carried out by taking water samples and sending them to the laboratory. The original samples need to be digested, distilled, and then manually titrated. The efficiency is low, the operation is complicated, and it is easy to misuse, and the water The secondary pollution caused by the sample transportation process will affect the objectivity of the test results. [0004] ORP titration is a titration analysis method based on electron transfer betwee...
