The features such as toxicity, carcinogenicity, mutagenicity.Traditional hexavalent chromium-treatments method mainly utilizes Chemical Physics method by Cr VI
It is reduced to trivalent chromium, but these methods can not play good real-time monitoring effect, it would be highly desirable to improve.
Summary of the invention
The purpose of this utility model is that in view of the drawbacks of the prior art and insufficient, provide that a kind of structure is simple, and design is closed
Reason, the prior-warning device easy to use for hexavalent chromium concentration in industrial wastewater, wastewater treatment efficiency is obvious, concentration monitor is quasi-
Really, it can be very good to detect national standard for the threshold value of content of 6-valence Cr ions in industrial wastewater.
In order to achieve the above purposes, the technical solution adopted by the utility model is:, and it is adopted comprising anode chamber, cathode chamber, data
Storage, computer, alarm；Wherein anode chamber is organic matter activated sludge, and cathode chamber is industrial wastewater；Anode chamber and cathode chamber
It is all set in same container, and cathode chamber is set to the top of anode chamber；It is connected between anode chamber and cathode chamber using conducting wire,
And data collector is in series in connecting wire, data collector is connect with computer, and computer is connect with alarm.
Further, resistance is parallel between the conducting wire connected between the anode chamber and cathode chamber.
After adopting the above structure, the utility model has the beneficial effect that described in the utility model a kind of for industrial wastewater
The prior-warning device of middle hexavalent chromium concentration, wastewater treatment efficiency is obvious, concentration monitor is accurate, can be very good to detect national standard
For the threshold value of content of 6-valence Cr ions in industrial wastewater, the utility model has structure simple, and rationally, it is excellent that cost of manufacture is low etc. for setting
Point.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only

Description of symbols:
Anode chamber 1, cathode chamber 2, data collector 3, computer 4, alarm 5, resistance 6.
Specific embodiment
The utility model will be further described below with reference to the accompanying drawings.
Referring to as shown in Figure 1, present embodiment the technical solution adopted is that: it include anode chamber 1, cathode chamber 2, number
According to collector 3, computer 4, alarm 5；Wherein anode chamber 1 is organic matter activated sludge, and cathode chamber 2 is industrial wastewater；Anode
Room 1 and cathode chamber 2 are all set in same container (internal to contain organic matter using measuring cup as container in present embodiment
Activated sludge constitutes anode chamber 1；Industrial wastewater is contained in the top of organic matter activated sludge, constitutes cathode chamber 2), and cathode chamber
2 are set to the top of anode chamber 1；It is connected between anode chamber 1 and cathode chamber 2 using conducting wire, and is in series with data in connecting wire
Collector 3, data collector 3 are connect with computer 4, and computer 4 is connect with alarm 5.
Further, it is parallel with resistance 6 between the conducting wire connected between the anode chamber 1 and cathode chamber 2, for protecting
Entire circuit.
The working principle of this specific embodiment:: anode chamber 1 is the activated sludge rich in organic matter, and cathode chamber 2 is to be checked
The Cr VI industrial wastewater of survey is connected anode chamber 1 and cathode chamber 2 by conducting wire, generates electron transmission, so that electric current is generated,
The current acquisition is sent to computer 4 by data collector 3, by the analysis software in computer 4 in electric current and waste water
Mathematical model is established between middle hexavalent chromium concentration, linear relationship is as follows: voltage=20.11 × concentration+153.61, related coefficient=
0.9935, the intuitive content that Cr VI is reacted by electric signal then triggers the alarm of alarm 5 when a threshold is exceeded, using sinking
The working principle of product object fuel cell, that is, using industry, sanitary sewage etc. is used as raw material, be it is a kind of can will be in organic matter
Chemical energy is converted into the device of electric energy under the action of microorganism；It has raw material extensive, mild condition, clean and effective etc.
Advantage；Using the principle of deposit fuel cell, Cr VI is generated as cathode electronics receptor by microbiological fuel cell
Electric signal, indicates the concentration of Cr VI in industrial wastewater, to reach good real-time monitoring effect, plays certain early warning and makees
With.
After adopting the above structure, present embodiment has the beneficial effect that one kind described in present embodiment is used for
The prior-warning device of hexavalent chromium concentration in industrial wastewater, wastewater treatment efficiency is obvious, concentration monitor is accurate, can be very good to detect
For national standard for the threshold value (0.5mg/L) of content of 6-valence Cr ions in industrial wastewater, present embodiment is simple with structure, if
The advantages that it is reasonable to set, low manufacture cost.
The above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, those of ordinary skill in the art couple
The other modifications or equivalent replacement that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope should all cover in the scope of the claims of the utility model.
