The fuel of microbiological fuel cell comprises sanitary sewage, high concentrated organic wastewater etc.It is had correlative study as waste disposal plant, a kind of microbiological fuel cell pile is disclosed as disclosing among the CN201117727Y among the direct microbiological fuel cell of a kind of continuous deflector type, the CN101315985B, they improve output rating and COD removal effect by the mode of series connection, still remain to be improved aspect self production capacity taking full advantage of.
Summary of the invention
The purpose of this utility model provides a kind of organic sewage treatment unit that comprises microbiological fuel cell that effectively utilizes self production capacity.
In order to solve the problems of the technologies described above, the utility model provides a kind of organic sewage treatment unit that comprises microbiological fuel cell, and it is achieved through the following technical solutions:
A kind of organic sewage treatment unit that comprises microbiological fuel cell, described microbiological fuel cell comprises that at least one comprises the combined electrode of anode, negative electrode and ion-exchange membrane, it is characterized in that, described battery also comprises a treatment sewage entrance and a processing back sewage outlet, there is a liquid thrust unit described treatment sewage ingress, the flow velocity that is used for the control treatment sewage, the power supply of described thrust unit are connected in the energy storage device of described microbiological fuel cell, an external source in parallel also simultaneously.
According to the utility model, described liquid thrust unit is pump.
According to the utility model, the number of described combined electrode is more than or equal to 2, and is connected in series; Preferably, the number of described combined electrode is 4; More preferably, the number of described combined electrode is 8.
The utility model can be used for handling multiple organic sewage, waste disposal plant of the present utility model has following beneficial effect: (1) realizes the temperature control of pending organic sewage by self production capacity, thereby realize the energy conversion process of microorganism better, effectively improve output rating and COD removal effect; (2) system operation is easy flexibly, and treatment effect is secure; (3) system's occupation of land is few, and capital cost is low.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Description of drawings
Fig. 1 is the structural representation of waste disposal plant of the present utility model.
Wherein the implication of each Reference numeral is as follows:
1 groove; 2 microbiological fuel cells; 3 combined electrodes; 4 water inlets; 5 water outlets; 6 temperature-control devices; 7 heating units; 8 energy storage devices; 9 entrances; 10 liquid thrust units; 11 outlets; 12 external sources.
Embodiment
The utility model is made detailed description by the invention of following embodiment.But the utility model is not limited to described embodiment, and many distortion can also be arranged.Those skilled in the art change or change from the institute that content disclosed by the invention directly derives or associates, and all fall into protection scope of the present invention.
According to the utility model, as shown in Figure 1, described waste disposal plant comprises that one holds the groove 1 of microbiological fuel cell, described groove 1 has a water inlet 4, a water outlet 5 and a temperature-control device 6, heating unit 7 in the described temperature-control device is the negative electrode of at least one combined electrode 3 of being connected described microbiological fuel cell 2 and at least one resistance wire between the anode, and this resistance wire is arranged in the water of described groove.When the temperature of water in the groove was lower than design temperature, temperature-control device starting resistance silk began heating, stopped heating behind the arrival design temperature.By such setting, realized taking full advantage of of self production capacity, simplified equipment, saved fund; In addition, realize the temperature control of pending organic sewage by self production capacity, thereby realize the energy conversion process of microorganism better, effectively improve output rating and COD removal effect.
Described microbiological fuel cell 2 comprises at least one combined electrode that comprises anode, negative electrode and ion-exchange membrane 3, comprise a treatment sewage entrance 9 and a processing back sewage outlet 11, there are a liquid thrust unit 10(such as pump in described treatment sewage ingress), the flow velocity that is used for the control treatment sewage, the power supply of described thrust unit 10 are connected in the energy storage device 8 of described microbiological fuel cell, an external source 12 in parallel also simultaneously.Therefore, the electricity (being the energy storage device 8 that power supply is connected in microbiological fuel cell, as resistance box) that the kinetic energy of described thrust unit 10 produces from microbiological fuel cell on the one hand is on the other hand from external source 12.When the waste disposal plant initial start stage, because the electrogenesis quantity not sufficient of microbiological fuel cell, the then main outer power supply power supply that connects of this thrust unit is in case but after microbiological fuel cell began normal electrogenesis, this thrust unit was just main by fuel cell-powered.Realized taking full advantage of of self production capacity.
The combined electrode 3 of described microbiological fuel cell can arrange one, preferably can connect to arrange at least two, more preferably arranges four, more preferably arranges eight or more.Thereby the output rating and the COD that improve battery remove efficient.
Be example with the beer waste water specifically, use device of the present utility model, can handle this waste water continuously and stably, the operational excellence of described temperature-control device and liquid thrust unit, electrogenesis is also stable, and the COD before handling in the waste water is 2800mg/L, and the COD after the processing is lower than 250mg/L.
