Intelligent pressure-sensitive type biochemical oxygen demand (BOD) measuring instrument

Abstract

The invention discloses an intelligent pressure-sensitive type biochemical oxygen demand (BOD) measuring instrument and belongs to the field of environment monitoring. The instrument adopts a pressure-sensitive principle, combines a pressure-sensitive integration module, a DIP constant-temperature reaction bottle and a microwave transmission module, and intelligently executes and prompts to finish process control flow by utilizing a microcomputer control and man-machine communication system, wherein the DIP constant-temperature reaction bottle performs complete stirring, quick oxygen inflation and constant-temperature adjustment on a water sample, and pressure-sensitive and temperature modules perform mutual correction, so that the dissolved oxygen and the temperature of the water sample achieve balance and dynamic balance; the pressure value of each reaction bottle is recorded by the pressure-sensitive module continuously and accurately, is transmitted to the measuring instrument in a microwave wireless transmission mode, is converted into the BOD value of each water sample by the measuring instrument, and then is synchronously displayed, mapped, printed, stored and transmitted; the measuring result is transmitted back to the pressure-sensitive integration module, and the BOD results of the measured water samples in respective reaction bottles can be displayed independently. The intelligent pressure-sensitive type BOD measuring instrument has the advantages of wide measuring range, high precision, simple and safe operation and the like, and is suitable for being generally popularized and applied.

Description

technical field [0001] The invention relates to a pressure-sensitive BOD measuring instrument for monitoring water quality pollution, in particular to an intelligent pressure-sensitive BOD measuring instrument. It belongs to the field of environmental water pollution monitoring. Background technique [0002] With the progress and rapid development of society and science and technology, various environmental protection issues that affect the living environment of human beings have attracted the attention of countries all over the world. Chemical, printing and dyeing, manufacturing and other industrial wastewater and people's daily domestic sewage discharge directly affect surface water and groundwater resources. These are all related to human health and the survival of animals and plants. We know that there are a wide variety of organic pollutants in industrial and domestic wastewater, and it is very difficult to determine the content of a certain component alone. However,...
