Description
Technical field
The present invention relates to water process and technical field of new energies, be specifically related to the rural domestic sewage treatment system of a kind of combination microbiological fuel cell and anaerobic manpower wetland.
Background technology
Along with the development of China's rural economy and improving constantly of life in the countryside level, the environmental pollution that domestic sewage in rural areas causes increases the weight of increasingly.
At present, China's domestic sewage in rural areas discharge capacity is about 8,000,000,000 90 hundred million t every year, and is continuously increased, but disposition allows of no optimist.The village of 96% does not has discharge conduit and sewage disposal system, and sanitary sewage arbitrarily discharges.The random discharge of domestic sewage in rural areas has become the main reason of rural areas in our country water environment pollution.
At present in China's distributing technology for treating domestic sewage in rural area, mainly based on anaerobic biogas generating pit treatment technology, stabilization pond treatment technology, Treatment Technology of Constructed Wetland, soil filtration technology etc..Wherein anaerobic manpower wetland technology has been widely used in rural domestic sewage treatment due to advantages such as its capital construction operating cost are low, easy and simple to handle, anti-shock loading performance is good.But anaerobic manpower wetland technology is relatively low for the treatment effeciency of sanitary sewage, effluent quality is usually unable to reach discharge standard, limits it and further applies.
On the other hand, utilizing the effect of microorganism to carry out energy conversion (such as the metabolism of carbohydrate or photosynthesis etc.), on the electron transmission that Repiration is produced to electrode, such device is microbiological fuel cell (MFC).Make biocatalyzer with microorganism, energy conversion can be carried out at normal temperatures and pressures.In recent years, MFC quickly grows, but never obtains large-scale actual application.Tracing it to its cause, electrode material is expensive, and efficiency of fuel cell generation is the most high, is the principal element restricting its engineer applied.
Summary of the invention
It is an object of the invention to overcome existing deficiency, it is provided that a kind of economic, practical, combination microbiological fuel cell of high treating effect and the rural domestic sewage treatment system of anaerobic manpower wetland.
Rural domestic sewage treatment system in conjunction with microbiological fuel cell Yu anaerobic manpower wetland includes water inlet, anode, anaerobic pond, collection and confinement of gases mouth, load, wire, negative electrode, mozzle, floral region, packing area, outlet；Anode, negative electrode it is provided with in anaerobic pond, anaerobic pond bottom is provided with water inlet, anaerobic pond top is provided with collection and confinement of gases mouth and collects biogas, anode is connected with load two ends by wire respectively with negative electrode, anaerobic pond top is connected with the artificial wet land system being made up of floral region and packing area by mozzle, and sewage flows out through outlet.
Described anode is material with carbon element, conducting polymer, CNT or the electrode of conducting polymer/carbon nano tube compound material.Containing anaerobic sludge and the mixed liquor of sewage in described anaerobic pond.The resistance of described load is 1000 ohm.Described wire uses titanium wire or copper conductor, and the insulated enclosure carrying out junction point processes.Described negative electrode is the electrode of porous, electrically conductive material.Described floral region planting plants is plant waterborne, phytobenthon, phytoplankton or large-scale emergent aquactic plant.Described packing area is made up of surface soil layer, middle level gravel, the little gravel of lower floor.
Due to the fact that the existence of electrode so that the speed of electron transfer improves, microbial metabolism speed is accelerated；Meanwhile, electrochemical action is incorporated in sewage disposal process by the existence of electrode so that the redox rate of pollutant is accelerated, and improves the treatment effect of sewage.And the raising of wastewater treatment efficiency, correspondingly can reduce the sewage time of staying in anaerobic pond, thus reduce the volume of anaerobic pond, reduce the floor space of system, saved land resource and reduced capital construction cost.On the other hand, owing to the planting cost of water plant is the lowest, and whole system is without using expensive permselectivity membrane and the traditional noble metal such as electrode material such as platinum, gold, significantly reduces operating cost.
