Embodiment 1

[0033] This example illustrates the specific structure and structure of the chlorella microbial fuel cell reactor of the present invention, as well as its working principle.

[0034] Chlorella microbial fuel cell reactor of the present invention such as figure 1 As described above, it is mainly composed of an anode chamber 1, a cathode chamber 2, an anode electrode 3, a cathode electrode 4, a wire 5, a load 6, a proton exchange membrane 7, and a three-phase separator 13; the anode chamber 1 communicates with the cathode chamber 2 And separated by proton exchange membrane 7; anode electrode 3 is arranged in the chamber of anode chamber 1, cathode electrode 4 is arranged in the chamber of cathode chamber 2, anode electrode 3 and cathode electrode 4 are arranged on the anode through wire 5 The external circuits outside the chamber 1 and the cathode chamber 2 are respectively connected to both ends of the load 6; the bottom side opening of the cathode chamber 2 is provided with a ...

Embodiment 2

[0044] This embodiment combines figure 2 A low-cost method for treating high-concentration organic wastewater using the chlorella cathode microbial fuel cell described in Example 1 is described.

[0045] 1) Start the reactor:

[0046] At room temperature, the domestic sewage or the anode effluent of the microbial fuel cell (as a bacterial source) and the anolyte are respectively injected into the anode chamber 1 through the water inlet 8 of the anode chamber 1; for OD 680 =0.5), and inject phosphate buffered saline (NaH 2 PO 4 2.452 g / L, Na 2 HPO 4 4.576 g / L, KCl 0.13 g / L, pH=7.0) and BG11 medium formula solution; the load 6 is connected between the anode electrode 3 and the cathode electrode 4 as a fixed-value resistor of 1000Ω to monitor the change of the resistance voltage. Domestic sewage with different initial COD concentrations or anode effluent from microbial fuel cells domesticate the anode flora step by step. / L, finally when the initial COD concentration is...

Abstract

The invention relates to a Chlorella microbiological fuel cell reactor, which belongs to the technical field of biological treatment, reuse and resource recovery of sewage. The reactor mainly comprises an anode chamber, a cathode chamber, leads, a load, a proton exchange membrane and the like, wherein, the anode chamber is separated from the cathode chamber through the proton exchange membrane, an anode is provided in the anode chamber, and a cathode is provided in the cathode chamber. According to the invention, the reactor is started, and anode flora in high-concentration organic waste water is domesticated and treated; the high-concentration organic waste water is allowed to enter into the anode chamber for anaerobic treatment by anode bacteria for 10 days at room temperature, anode effluent is allowed to enter into the cathode chamber for in-depth denitrification and dephosphorization and further absorption of organic matters by cathode Chlorella, and final effluent reaches the third level discharge standard of urban sewage treatment; the cathode Chlorella is collected, and crude grease of biodiesel is extracted. The invention enables low cost treatment of high-concentration organic waste water to be realized and allows clean effluent to be obtained and electric energy and biodiesel to be recovered, thereby genuinely realizing resource utilization of the waste.

Description

technical field [0001] The invention belongs to the technical field of wastewater biological treatment reuse and resource utilization, and relates to a chlorella microbial fuel cell reactor, in particular to a chlorella cathode microbial fuel cell reactor for high-concentration organic wastewater treatment. Background technique [0002] The wastewater generated by human social activities is mainly organic wastewater, which is also the most harmful wastewater to the human living environment. Effective treatment of organic wastewater is a major issue facing human beings. High-concentration organic wastewater is a serious water pollutant. Due to its complex composition and toxicity to the human body, countries have invested a lot of manpower and material resources in research. At present, biochemical methods are commonly used at home and abroad to treat wastewater by using indigenous microorganisms in sludge to degrade organic matter. According to whether aeration is required ...
