Abstract
The invention discloses a sewage biochemical oxygen demand (BOD) scattering detecting table.The sewage BOD scattering detecting table comprises a scattering detecting device and a detecting table sewage pipe, wherein the scattering detecting device and the detecting table sewage pipe are arranged on a sewage pipe of a sewage tank; a scattering LED single-color light source, a transparent detecting chamber, a lens and a photoelectric sensor are arranged inside the scattering detecting device, and an output signal is transmitted to a computer through a filter amplifier and a microprocessor.Sewage performance parameters can be comprehensively, rapidly and accurately tested through the sewage BOD scattering detecting table, so that the performance of a water body is improved.
Description
Technical field
The present invention relates to performance testing device, especially sewage BOD scattering formula monitor station.
Background technology
The life of the mankind and production activity all be unable to do without water, the water taken from nature is contaminated owing to having infiltrated various pollutant, change the physics that natural water is original, chemical or biological composition and character, even lose use value, then outer row is discarded, this water going out of use outer row is called sewage. sewage is originated by it, sanitary sewage and the big class of trade effluent two can be divided into, in general, the index of sewage is checked to have following: COD, BOD, colourity, float, heavy metal etc..
Sewage physics parameter test method all uses sensor on-line testing at present, but owing to sewage contains significantly high stickup liquid, have on sensor and be stained with mucus, make sensor lose sensitivity, optic test can at a high speed, detect in real time, be the developing direction of sewage discharge performance test.
Currently without sewage performance parameter is carried out optic test tester and method of testing.
Therefore design sewage scattering formula testboard, has important meaning for grasping its performance parameter, improving cesspool clean-up effect.
Summary of the invention
It is an object of the invention to provide a kind of sewage BOD scattering formula monitor station, can real-time, efficient detection wastewater parameters.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of sewage BOD scattering formula monitor station, including the soil pipe being arranged on the right side of cesspool, the right side of soil pipe is connected with the water inlet of transparent sensing chamber, consolidates with outlet pipe on the right side of transparent sensing chamber；Described transparent sensing chamber is arranged on the middle part of scattering formula detecting device frame, is provided with scattering formula LED monochromater, transparent sensing chamber, lens, photoelectric sensor successively from top to bottom in described scattering formula detecting device frame；The output signal of photoelectric sensor delivers to computer by filter amplifier, dsp processor.
Described emitter scattering formula LED monochromater launches the light of specific wavelength, and LED monochromater is installed with photoelectric sensor straight line each other, and photoelectric sensor is arranged in the focus of lens.
The tail water passage of described soil pipe composition is mutually perpendicular to layout with detection light paths of LEDs monochromater, transparent sensing chamber, lens, photoelectric sensor.
Described transparent sensing chamber is circular configuration, and diameter is more than the diameter of soil pipe and outlet pipe.
Compared with prior art, the invention has the beneficial effects as follows: owing to adopting technique scheme, it is possible to detecting the parameter of sewage, therefore the present invention reaches the purpose of test sewage performance parameter comprehensive, quick, accurate.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
In order to make technical scheme become apparent from, below in conjunction with accompanying drawing 1, the present invention is described in detail.It should be appreciated that the detailed description of the invention described in this specification is only used to explain the present invention, it is not intended to limit protection scope of the present invention.
The invention discloses a kind of sewage BOD scattering formula monitor station, including the soil pipe 3 being arranged on the right side of cesspool 2, the right side of soil pipe 3 is connected with the water inlet of transparent sensing chamber 10, consolidates with outlet pipe 11 on the right side of transparent sensing chamber 10；Described transparent sensing chamber 10 is arranged on the middle part of scattering formula detecting device frame 4, is provided with scattering formula LED monochromater 5, transparent sensing chamber 10, lens 6, photoelectric sensor 7 successively from top to bottom in described scattering formula detecting device frame 4；The output signal of photoelectric sensor 7 delivers to computer 1 by filter amplifier 8, dsp processor 9.
Described emitter scattering formula LED monochromater 5 launches the light of specific wavelength, and LED monochromater 5 is installed with photoelectric sensor 7 straight line, and photoelectric sensor 7 is arranged in the focus of lens 6.
The tail water passage of described soil pipe 3 composition is mutually perpendicular to layout with detection light paths of LEDs monochromater 5, transparent sensing chamber 10, lens 6, photoelectric sensor 7.
Described transparent sensing chamber 10 is circular configuration, and diameter is more than the diameter of soil pipe 3 and outlet pipe 11.
The work process of the present invention is: cesspool 2 rotating speed, load are controlled by computer control system 1, is accessed in scattering formula detecting device by sewage by cesspool soil pipe 3, measures each component content in draining, and data are uploaded to computer 1.
Scattering formula detecting device work process is: using scattering formula LED monochromater 5 as emitter, photoelectric sensor 7 is as receptor, the light that scattering formula LED monochromater 5 sends is irradiated to transparent sensing chamber 10, when sewage is by transparent sensing chamber 10, the intensity of light will change, and light is received by photoelectric sensor 7 after lens 6, produce the electric impulse signal that the size with particulate matter is ratio, by filter amplifier 8, dsp processor 9 sampling processing, signal is delivered in computer 1.
Preferably, the present invention adopts correlation type detection mode, and mutual to emitter and receptor correlation is installed, and makes the luminous energy that emitter sends enter receptor.When there being detection object to enter between emitter and receptor, measured object will shield lights and cause that the light quantity entering receptor reduces, just can detect the content of measured object according to the change of receptor light quantity.The method stability is high, response is fast, it is smaller to affect.
