Description

technical field

[0001] The invention relates to an on-line monitor for biochemical oxygen demand (BOD) of water quality, in particular to a sensor-type on-line monitor for biochemical oxygen demand. Background technique

[0002] Biochemical oxygen demand is an important indicator for analyzing the content of organic pollutants in water bodies, and is one of the most important parameters in routine monitoring of water quality. The current standard dilution method (BOD 5 method) has many deficiencies, such as long time, heavy workload, cumbersome operation, many interference factors, poor repeatability, and cannot reflect water quality changes in time, and cannot realize online monitoring of water quality.

[0003] In recent years, some new measurement methods have appeared one after another, among which microbial film sensors and microbial reactors are the main ones. Microbial reactor type rapid BOD analyzer, representative products such as Biomonitor produced by German LAR...
