Description
Technical field
The present invention relates to a kind of optic probe, relate in particular to a kind of probe that is applied to the portable COD monitor of sewage detection.
Background technology
Chemical oxygen demand (COD) Chemical-Oxygen-Demand is called for short COD, is meant the content that easily is converted to oxygen in the water by the amount result of the oxygenant that reducing substances consumed of strong oxidizer oxidation, in mg/L.It is the overall target of reducing substances in the expression water body, and reducing substances comprises in the water: organism, and nitrite, ferrous salt, sulfide etc., the organic pollutants in the water body are very general.Therefore COD becomes one of index of organism relative content, also is an important indicator of environment monitoring.Organism dissolved oxygen DO and cause the loss of oxygen in biodegradation process in natural circulation, the disappearance of dissolved oxygen DO can destroy environment and biocenological balance, and brings harmful effect, thereby causes that water body worsens.Therefore, COD is as the research of river and industrial waste water, and an important parameters of sewage treatment plant, is subjected to the attention of each country.On Dec 8th, 2000; point out in the environment supervision instrument development guide of State Environmental Protection Administration's issue; at present in the environment supervision instrument that China gives priority to; comprise the COD on-line monitoring analytical instrument that is used for industrial pollution source or Sewage outlet; point out simultaneously environmental monitoring and monitoring instrument development trend for present artificial sample and lab analysis serve as main to; automation and intelligentification and network turn to main monitoring direction development; environment supervision instrument will be to high-quality; multi-functional; integrated; robotization, systematization and the development of intelligentized aspect.Environment supervision instrument is to physics, chemistry, biology, the high-tech sector development that technological synthesiss such as electron optics are used.
Existing portable COD mainly is made up of optical system and Measurement and Control System.Optical system is made up of fibre-optical probe and spectrometer.The ultraviolet-visible that light source sends enters probe, and the survey sewage of the probe of being flowed through absorbs, and the light that carries tested sewage absorption information is coupled into optical fiber after lens converge, send into spectrometer through Optical Fiber Transmission and carry out beam split, sampling, obtains the absorption spectrum of sewage.Fibre-optical probe is by optical fiber, and collimating mirror and catoptron are formed.Twin-core fiber single core end one end wherein connects pulse xenon lamp, and the other end connects fiber spectrometer; The twin-core end links to each other with collimating mirror.Light is sent by the light source pulse xenon lamp, and after collimating mirror was dispersed, toward mirror after mirror reflects, was injected fiber spectrometer.Existing sonde configuration is comparatively complicated, and catoptron and collimating mirror directly distance are non-adjustable, and the COD that is not suitable under the multiple environment detects.
Summary of the invention
For the technological deficiency that the probe that solves above-mentioned portable COD monitor exists, the purpose of this invention is to provide a kind of probe of portable COD monitor, the characteristics of the testing environment of simple in structure, suitable multiple complexity that this probe has.
In order to realize above-mentioned technical purpose, the present invention has adopted following technical scheme:
Portable probe of chemical oxygen demand (COD) monitor, this probe comprise reflection probe tube, mirror unit, reflecting optics, collimating mirror, waterproof terminal and push rod; The reflection probe tube is provided with upper shaft hole and lower shaft hole, and the sidewall of reflection probe tube is provided with two openings, and two openings are symmetrical arranged and are communicated with lower shaft hole respectively, and on the sidewall of reflection probe tube the arc connector are set, and the arc connector connects two openings; Described mirror unit is arranged in the lower shaft hole, mirror unit and axis hole threaded engagement or be slidingly matched, and described push rod is fixedly installed on the lower end of mirror unit, and the upper end of mirror unit is provided with the slide glass hole, and described reflecting optics is arranged in the slide glass hole; Described collimating mirror is fixedly installed on the upper shaft hole, and the waterproof terminal is arranged on the upper end of collimating mirror.
As preferably, two above-mentioned openings are respectively runway shape, and the lower end of opening is an arcwall face.As preferred again, this probe also comprises optical fiber, and optical fiber connects collimating mirror by the waterproof terminal.
The present invention has characteristic of simple structure owing to adopted above-mentioned technical scheme, and it is thick to change water by the distance between change catoptron and the collimating mirror, and then changes range, can be suitable for the testing environment of multiple complexity.
