Description
Technical field
The utility model relates to a kind of COD water quality on-line monitoring system, belongs to environmental monitoring technology field.
Background technology
Chemical oxygen demand (COD) (COD) is under certain conditions, when adopting certain strong oxidizer process water sample, and the oxidant content consumed.It is the index representing that in water, reducing substances is how many.Reducing substances in water has various organism, nitrite, sulfide, ferrous salt etc., but importantly organism.Therefore, chemical oxygen demand (COD) (COD) is again often as weighing the how many index of Organic substance in water matter content.Chemical oxygen demand (COD) is larger, illustrates that water body is more serious by organic pollution.The measuring method of current COD mainly contains chemical method and Physical two kinds.Chemical method is with strong oxidizer by the reducing substances oxidation in water sample, then calculates the consumption of oxygenant, is finally converted to the amount of oxygen consumed.Potassium dichromate and permanganate indices method measure the typical method of COD in current chemical method.Permanganimetric method is used for analyzing cleaner surface water, underground water, potable water, and namely low strength COD is measured; Potassium dichromate method is used for the analysis of industrial waste water and sanitary sewage, and namely the COD of higher concentration measures.Be widely used in Coulomb equation, colourimetry, Catalytic digestion method, TOC scaling method, Microwave Digestion etc. in addition that laboratory COD measures.Physical mainly based on the ultraviolet absorptivity method of Lambert-Beer law, i.e. UV (Ultraviolet) method.Current COD measuring instrument both domestic and external mostly adopts double UV check method, same light source is divided into two bundles by double UV check method, respectively through two monochromators (254nm and 546nm), obtain the monochromatic light of two bundle different wave lengths, utilize chopper to make two-beam alternately irradiate same absorption cell with certain frequency, then received by detecting device.The treated system-computed of signal draws the absorbance difference of two wavelength, and namely absorbance difference is directly proportional to sample concentration.To the device that the COD of water body measures, such as Chinese patent literature CN201974376U discloses a kind of COD online water analysis instrument, measures chemical oxygen demand value by the change of water sample color.
In prior art, only once gather the current of a certain period and once analyze during usual on-line monitoring water quality, this makes the possibility occurring error greatly improve, a single monitoring device or trace routine breaks down or flaw, is easy to cause monitoring error.
Utility model content
Therefore, the purpose of this utility model is to overcome defect of the prior art, provides one by once adopting water, repeated detection, thus can reduce the COD water quality on-line monitoring system of monitor and feedback.
To achieve these goals, a kind of COD water quality on-line monitoring system of the present utility model, comprise water sampling system and multiple COD online water analysis instrument, described water sampling system comprises end to end multiple U-shaped pipe successively, and the quantity of described U-shaped pipe is consistent with the quantity of described COD online water analysis instrument; The first end of first of multiple described U-shaped pipe is connected with intake pipe, and last one end of last of multiple described U-shaped pipe is connected with water pump; The lower end, middle part of multiple described U-shaped pipe is respectively arranged with the chamber that connecting pipe is communicated with described U-shaped pipe, and described connecting pipe is provided with valve; Multiple described connecting pipe correspondence is connected to multiple described COD online water analysis instrument.
Described COD online water analysis instrument is three.
Also filtrator is provided with between described U-shaped pipe and described water pump.
Described water pump is provided with return pipe away from one end of described U-shaped pipe.
Adopt technique scheme, COD water quality on-line monitoring system of the present utility model, sampled by the current of water sampling system to the same period, draw water in particular by water pump, water sample is by entering multiple U-shaped pipe successively after intake pipe, then by opening valve, water sample in U-shaped pipe correspondence flows in multiple COD online water analysis instrument and detects, by machine or manually calculate mean value after testing result draws.Usually three COD online water analysis instrument can be used.And between described U-shaped pipe and described water pump, be also provided with filtrator, the impurity in water sample can be filtered, avoid damaging water pump.By return pipe, unnecessary water sample is drained back in current, need not subsequent treatment cost be increased, without the need to other waste water reclamation apparatus.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, set forth the utility model further.In the following detailed description, the mode only by illustrating describes some one exemplary embodiment of the present utility model.Undoubtedly, those of ordinary skill in the art can recognize, when not departing from spirit and scope of the present utility model, can revise by various different mode to described embodiment.Therefore, accompanying drawing is illustrative with being described in essence, instead of for limiting the protection domain of claim.
As shown in Figure 1, the present embodiment provides a kind of COD water quality on-line monitoring system, comprise water sampling system 1 and multiple COD online water analysis instrument 2, described water sampling system 1 comprises end to end multiple U-shaped pipe 11 successively, and the quantity of described U-shaped pipe 11 is consistent with the quantity of described COD online water analysis instrument 2; The first end of first of multiple described U-shaped pipe 11 is connected with intake pipe 12, and last one end of last of multiple described U-shaped pipe 11 is connected with water pump 13; The lower end, middle part of multiple described U-shaped pipe 11 is respectively arranged with the chamber that connecting pipe 14 is communicated with described U-shaped pipe 11, and described connecting pipe 14 is provided with valve 15; Multiple described connecting pipe 14 correspondence is connected to multiple described COD online water analysis instrument 2, and described COD online water analysis instrument 2 can be a kind of COD water quality analyser of the prior art.
