Description
Technical field
The present invention relates to a kind of wastewater processing technology, a kind of specifically microbiological fuel cell is cultivated to combine with little algae and is handled the method and the isolated plant thereof of organic waste water.
Background technology
The a large amount of organic waste water of the annual generation in the whole world, traditional biological wastewater treatment process not only need consume lot of energy, and produces a large amount of mud, and also very high to the processing costs of mud.Thereby need the high and low substitute technology of cost of development efficiency.Meanwhile, energy shortage also is the main bottleneck of restriction 21 century human development.Therefore exploiting economy, novel energy is imperative efficiently, wherein biological new forms of energy are mainly to study one of focus.(Microbial fuel cell, MFC) be is catalyst oxidation organism and the device that produces electric current with the mikrobe to microbiological fuel cell.MFC has overcome the shortcoming of traditional biological wastewater treatment process, is a kind of emerging wastewater treatment and the biological wastewater treatment new technology of synchronous electrogenesis.The biological process of wastewater treatment that the MFC technology is traditional relatively has many advantages, and wherein maximum advantage is when handling waste water, can obtain electric energy, thereby can offset the part running cost of waste water treatment plant.In addition, microbiological fuel cell can make the electric weight that consumes because of aeration in the Wastewater Treated by Activated Sludge Process waste water process reduce by half, and makes the sludge quantity of generation reduce 50-90%.At present, MFC has been applied to the processing while electrogenesis of various waste water, comprises sanitary wastewater and trade effluent.(concentration representes COD) to have good effect of removing with COD Chemical Oxygen Demand to MFC, utilizes the MFC can be with the organic matter removal of 80-99% in the waste water to the organism in the waste water.Though it is not MFC has good effect of removing to the COD in the waste water, but good to the removal effect of nitrogen and phosphorus.In order to improve the clearance of nitrogen, MFC combined with other method of denitrogenating developed many association systems.Though these systems can improve the clearance of nitrogen, exist nitrogen remove not exclusively or system too complicacy be not easy to deficiencies such as amplification, and do not pay close attention to the removal of phosphorus.Contain many nitrogen, phosphorus and other nutritive ingredient in the waste water after MFC handles, can not satisfy relevant emission standards.
Meanwhile, many researchs show that little algae has good effect of removing to nitrogen and phosphorus in sewage work's two heavy overflow sewages, and can obtain biomass.But present little algae also can't directly utilize sewage.Because solid particulate matter in the sewage and suspended solid are more, cause the transmittance of sewage very low.Therefore before using, must remove solid particulate matter and suspended solid in the sewage with the raising transmittance through methods such as filtration, this process not only consume energy and efficient low.The organic concentration that exists in the sewage simultaneously is higher, helps the growth of bacterium, and the raised growth of bacterium breeding is unfavorable for even suppresses micro algae growth.
Summary of the invention
