Abstract

An on-line monitoring instrument of COD concentration by a UV method relates to a piece of monitoring equipment of the COD concentration and belongs to the field of environment water quality monitoring. The equipment is to solve problems of complicated operation, long response time and production of secondary pollution existing in the prior COD monitoring methods. The invention consists of a light path system, a water way system, a circuit system and an embedded system; the light path system is arranged in the water way system; the light path system is connected with the circuit system; the circuit system is connected with the embedded system; the circuit system amplifies the weak electric signal of the light path system, converts into digital signal and sends to the embedded system; the embedded system analyzes and calculates the received digital signal, saves the result and sends to a display module to display to the user in forms of digits or tables. The on-line monitoring instrument has the advantages of easiness in operation and maintenance, low failure rate, no need of adding chemical reagent, no secondary pollution, short test time, response time generally within 1min and capability of realizing real on-line monitoring.

Description

technical field [0001] The invention relates to a device for monitoring COD concentration, which belongs to the field of environmental water quality monitoring. Background technique [0002] In water quality monitoring, COD (Chemical Oxygen Demand, chemical oxygen demand) monitoring is an important item in environmental monitoring. COD refers to the amount of strong oxidant consumed by reducing substances in the water when wastewater is treated with a strong oxidant under certain conditions, and the result is converted into oxygen content (in mg / L). COD is an important index to evaluate the pollution degree of water body by organic matter, and it is an important parameter for the research of river and industrial wastewater and the evaluation of the treatment effect of sewage treatment plants. The smaller its value, the lighter the water pollution. [0003] There are many methods for the determination of COD, which are mainly divided into chemical methods and physical metho...
