Problems solved by technology

Traditional BOD 5 The measurement method has a long measurement cycle, many interference factors, poor repeatability, and large errors, which cannot reflect changes in seawater quality in time
In order to solve this problem, there have been many new detection BOD 5 A method wherein BOD is measured using a microbial sensor 5 The method is widely used, but due to the harsh selection conditions for microbial species, the broad spectrum of organic matter degradation is poor, and the microorganisms in the water sample will also affect the types and quantities of fixed microorganisms, resulting in unstable measurement results and unsatisfactory measurement results.

Abstract

The invention discloses a seawater measurement method based on a seawater in-situ culture microbial film, which comprises the following steps of carrying out microbial culture on an aerated seawater sample to obtain a microbial film, measuring the endogenous respiration value of the microbial film, measuring the exogenous respiration value of the microbial film of the water sample to be measured, and measuring the biochemical oxygen demand of the water sample to be measured. The seawater measurement method based on the seawater in-situ culture microbial film achieves the technical effect of simple and reliable measurement.

Description

technical field [0001] The invention relates to the field of water body pollution measurement, in particular to a seawater measurement method based on seawater in-situ cultivation of microbial films. Background technique [0002] At present, water pollution has become a worldwide problem. Domestic industrial wastewater contains various organic and inorganic substances, which are discharged into the sea without proper treatment, which has brought negative impacts on marine organisms and aquatic resources, and damaged the water environment. Biochemical oxygen demand (BOD), one of the important indicators to measure the degree of water pollution, refers to the dissolved oxygen consumed in the biochemical process of decomposing certain oxidizable substances in water under specified conditions, especially in the biochemical process of decomposing organic matter. Generally, 5 days are used as the standard time for determining biochemical oxygen demand, which is called five-day bio...
