According to the method, the microbial fuel cell is coupled with biological sewage treatment process including an aerobic pool, an anoxic pool and (or) an anaerobic pool, and the chemical energy of organic compounds in the untreated sewage is converted into electrical energy through microbial fuel cell technology, thereby reducing residual sludge produced in the biological sewage treatment process and lowering total cost of the sewage treatment process (including sludge treatment). With the method provided by the invention, sludge produced in the biological sewage treatment process can be reduced by 20 to 60%.
Description
Technical field
The invention belongs to technical field of sewage, particularly microbiological fuel cell is coupled to the method for carrying out original position mud decrement in biological wastewater treatment process.
Technical background
Mud is a kind of by product produced in biological wastewater treatment process, is also a kind of important organic waste.Can produce a large amount of mud in biological wastewater treatment process, the sludge of sewage treatment plant productive rate of actual motion can reach 0.52 ~ 1.22kgSS/kgBOD
5, according to statistics, current wastewater treatment in China ability about 1.53 billion cubic meters/day, produce more than 3,500 ten thousand tons, the mud of water content 80% year, along with China's expanding economy from now on, sewage load and wastewater treatment rate will constantly increase, and the output of the mud thereupon produced also will get more and more.Because pollutent a lot of in sewage can finally have been transferred in mud in biological wastewater treatment process, therefore mud must obtain dealing carefully with disposal.But due to the investment of specific resistance to filtration and working cost huge, the 20%-40% of the investment of whole sewage work and working cost can be accounted for, have even up to 65%, specific resistance to filtration has become the heavy burden and a difficult problem that sewage work faces, reduces sludge quantity very necessary.According to finding display, the mud that wastewater treatment in China factory produces, about has 80% not dealt carefully with, and mud is arbitrarily stacked and the pollution that causes highlights with secondary pollution problem, and causes social concern.
The method of current solution sludge problem can be divided into two classes: (1) is under the prerequisite ensureing standard water discharge, proper technology is adopted to reduce the sludge quantity produced in sewage treatment process, the output of mud is reduced, namely usually said sludge reduction from " source "; (2) after mud produces, certain Method and Technology is utilized to carry out process disposal, as anaerobic digestion+Land_use change, compost+Land_use change, burning+building materials utilization etc. to carrying out mud., also there is many problems in the ultimate disposal of mud in Equations of The Second Kind method, the acceptance problem of such as people, the amount of dissolving finiteness problem, secondary pollution problem, location problem and energy consumption problem etc. at present.Therefore, in the face of current day by day serious sludge problem, the Sludge Reduction Technologies being target with " Sources controlling ", is subject to people and more and more pays close attention to and pay attention to." source " Sludge Reduction Technologies comprises molten born of the same parents-recessive growth, endogenous respiration, uncoupling metabolism and microorganism predation etc. at present.
Microbiological fuel cell (Microbial Fuel Cell) is a kind of device that the chemical energy in organism can be converted under the effect of microorganism electric energy, is a kind of new technology that simultaneously can process pollutent and production capacity recently occurred in field of environment protection.As a kind of brand-new wastewater processing technology, microbiological fuel cell no longer only using the organic matter in waste water as removal object, but regard a kind of energy as.Utilize microorganism to be electric energy by chemical energy organic in waste water, not only purified sewage but also obtained energy, this is undoubtedly the significant innovation of sewage disposal theory, has immeasurable development potentiality.Compared with traditional anaerobic digestion, also the microbiological fuel cell of production capacity can have the advantage of some uniquenesses, such as process low concentration wastewater, operating temperature can lower than 20 DEG C etc., and these all make this technology have very strong competitive power and suitability.In recent years, microbiological fuel cell has had and has applied more and more widely, as glucose simulated wastewater, sanitary sewage, brewing wastewater, food processing wastewater, breeding wastewater and garbage leachate etc. in the organic waste water of process industry-by-industry.In addition, owing to containing large amount of organic in mud, these organism are mainly protein and carbohydrate, and therefore mud also as the electrogenesis matrix of MFC, can synchronously realize sludge reduction and resource utilization.
But be applied in the research of sewage treatment process current by microbiological fuel cell technology, investigator more pays close attention to the efficiency of fuel cell generation of wastewater treatment efficiency and microbiological fuel cell, and seldom pays close attention to for the mud produced in sewage treatment process.The low efficiency of fuel cell generation of current microbiological fuel cell have impact on the application of this technology.If when microbiological fuel cell is applied in sewage treatment process, consider that it produces the mud in wastewater treatment efficiency and sewage treatment process and brings economic results in society and environmental effect more, exploitation is conducive to the technique of the coupling microbiological fuel cell technology that mud generation reduces in biological wastewater treatment process, then may promote microbiological fuel cell and apply in sewage treatment process.Therefore, develop a kind of original position sludge reduction method of the microbiological fuel cell technology that is coupled, for the application etc. reducing cost and promotion microbiological fuel cell that mud in biological wastewater treatment process produced, reduced whole sewage treatment process (comprising sludge treatment), there is important practical significance.
