Online monitoring system for ammonia nitrogen in water quality

Abstract

The invention discloses an online monitoring system for ammonia nitrogen in water quality. The system comprises a closed hollow reaction body, a water sample addition component, a reagent addition component, a gas addition component and a detection component, wherein the water sample addition component and the reagent addition component are connected with the reaction body through a water pipe and a reagent pipe respectively; the gas addition component and the detection component are connected with the reaction body through a first gas pipe and a second gas pipe respectively; an ammonia sensor is arranged on the second gas pipe, and the reagent addition component is used for adding a solution of sodium hydroxide into the reaction body. The online monitoring system for the ammonia nitrogen in the water quality is simple and reasonable in structure, and an operating method is simple; the ammonia nitrogen content of a water sample can be detected with only an alkaline solution rather than other reagents, and the system has the advantages of reagent saving, reduction in manual reagent replacement frequency and running cost, elimination of waste liquor waste and the like.

Description

technical field [0001] The invention relates to the technical field of water quality detection equipment, in particular to an online monitoring system for water quality ammonia nitrogen. Background technique [0002] Water is a precious resource for human production and development, an important part of all living organisms, and one of the most basic and active elements in the environmental system (atmosphere, bio-soil, lithosphere surface). In recent years, with the rapid economic development and the acceleration of the urban process, the pollution of rivers and the deterioration of the ecological environment have caused 50% of the world's water resources to be polluted to varying degrees, resulting in a shortage of fresh water resources. At the same time, due to the application of complex chemical reagents, the problem of water environmental pollution has become increasingly complex and diverse, and the water environment is facing a more severe situation. In order to alle...
