Non-contact type pollutant concentration diffusion detection system and method

Abstract

The invention discloses a non-contact type pollutant concentration diffusion detection system and method. A device part comprises a water-groove still water simulation device, a jet flow simulation device and a camera. The water-groove still water simulation device comprises a water storage box, an experiment water groove, a first constant-flow pump, a first flow guiding channel, a second flow guiding channel, a third flow guiding channel, an overflow channel, a valve, a flow weir plate, a support, a waste liquid collecting box, a water barrel and an LGY-II propeller-type current meter. The jet flow simulation device comprises a liquid storage box, a fourth flow guiding channel, a rotor flow meter, a flow control valve, a T-type porous diffusion device and a jet flow pipe. The non-contact type pollutant concentration diffusion detection system is simple and reasonable in structure, high in generality, convenient to maintain and capable of simulating the concentration diffusion of water body pollution under external conditions; a low-cost free-pollution chemiluminescence reagent is used for replacing an existing fluorescent solution to determine the concentration field of pollutant discharging, the requirement of the device is lowered, and energy is saved.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a non-contact pollutant concentration diffusion detection system based on the principle of chemiluminescence and a method thereof. Background technique [0002] In recent years, due to the rapid development of my country's social economy, the problem of environmental pollution has become increasingly serious. Due to the strong flow characteristics of rivers, river ecosystems are easily affected by external pollution. Moreover, once a surface water pollution incident occurs, it is easy to affect the entire river basin. At the same time, after the surface water is polluted, it will further affect the ecology of the surrounding land, affect the ecology of lakes and reservoirs in the basin, and also affect the ecosystems of downstream estuaries, bays, and oceans. Therefore, the pollution of river water environment is far more harmful than static water bodies such as lakes an...

Problems solved by technology

However, the traditional detection method of ion concentration is mostly a contact single-point concentration measurement method, which is difficult to quickly and intuitively obtain the concentration distribution of ions in space.

In recent years, advanced flow display and measurement methods developed at home and abroad, such as PIV technology, laser-induced fluorescence and holographic interference technology, etc., are due to small measurement areas (generally only a few square centimeters), high prices, and harsh requirements for the use environment. Greatly limit its application in concentration field measurement
