Description

Time-sharing independent BOD detection device

Technical Field

The utility model relates to an environment water quality testing technical field especially relates to an independent BOD detection device of time sharing.

Background

In the process of protecting the water environment, the water quality detection and the water quality treatment play a vital role. It is known that a great variety of organic pollutants exist in industrial and domestic wastewater, and after a water body is polluted by the organic matters, the water body needs to consume a large amount of dissolved oxygen when decomposing the organic matters, so that the water body balance is damaged, the water body is deteriorated, fish and other aquatic organisms die due to oxygen deficiency, and the pollution accidents are frequently reported at present. The species of organic matters in the water body are complex and various, and single components of the organic matters cannot be measured, but the content of the organic matters in the water body is indirectly expressed by using oxygen consumed by the organic matters in water under specific conditions, and the biochemical oxygen demand belongs to such important indexes.

BOD Chinese name Biochemical Oxygen Demand (Biochemical Oxygen Demand). BOD refers to dissolved oxygen consumed by biochemical processes that microbially break down certain oxidizable substances in water, particularly organic matter, under specified conditions.

BOD 5: since the biological oxidation process of BOD takes a long time to perform, it takes more than 100 days to complete the process if cultured at 20 ℃. At present, the BOD5 value is generally selected at home and abroad as the BOD value. BOD5 means that the amount of dissolved oxygen consumed by culturing the sample in the dark at (20. + -.1) ℃ for 5 d. + -.4 h, generally corresponds to about 70% of the total BOD.

The main methods of the instruments for detecting BOD on the market at present are a dissolved oxygen detection dilution inoculation method, a biosensor method, a coulometer method, a mercury pressure difference method, a mercury-free pressure difference sensing method and the like. At present, the universal standard of BOD detection in China is 'determination dilution and inoculation method of five-day biochemical oxygen demand (BOD5) of HJ 505-2009 water quality'. Combining the standard, considering the factors of simple operation, accuracy of detection result, safety of experiment and the like, the BOD detection instrument of the current mercury-free differential pressure sensing method is the most suitable instrument for BOD detection.

When a BOD detection instrument of the mercury-free differential pressure sensing method detects BOD, a water sample is directly added for detection, and the operation is simple; the main working principle of the instrument for detecting BOD by the mercury-free differential pressure sensing method on the market at present is to simulate the natural degradation of BOD in a sealed culture bottle, and a pressure sensing device is arranged above the culture bottle or is connected to the pressure sensing device of a host machine through a sealing pipe, so that the pressure change in a sample of the culture bottle is detected.

The detection process of the existing BOD detection instrument can not be interrupted, and the samples can not be increased midway.
