Abstract: The present invention is about a treatment method of waste water generated in food processing plant by two position aeration process which solve environmental reformation and environmental pollution. The present invention comprises a process of filtering process material with screen, inflowing filterate in first settling tank and sending residual to thickener; a process of mixing process material inflowed in first settling tank with sludge recycled from second settling tank also the last settling tank; a process of sending sludge to thickener by solid-liquid separation with gravity in first thickener, diluting supernatant with dilution water and inflowing ore position aeration bath by controlling pH; a process of transfering process material accumulating in one position aeration tank at a long time and removing organic matter and pollution matter and like this in second settling tank; a process of recycling sludge first settling tank and transfering supernatant to one position aeration tank by solid-liquid separation process material with gravity in second settling tank; a process of absorbed decomposition fine floc formed by residual and first aeration using aerobic microorganism adhesive to porous plate filter medium having flexibility in second aeration tank; a process of effluxing supernatnat and internal recycling a part and the rest to first settling tank by solid-liquid separation with gravity transfering process material said process to last settling tank; a process of dehydrating in thickening sludge in thickener desiccator.

Abstract: The organic compositions in livestock's feces which are discharged from livestock production facilities were somewhat eliminated by using the decomposition and proliferation of aerobic microorganism, wherein the moisture in feces was evaporated and the pathogene fungi were disinfected by the biological energy resulted in the decomposition process with minimizing the loss of nutrient such as nitrogen in feces to give organic barnyard manure. The livestock's feces were mixed with sawdust and rice hull for controlling the moisture to 65% and the mixture was contacted with aerobic microorganism by aeration through the bottom air feeder, followed by decomposition of organic composition in feces. The temperature in reactor was ascended by the microorganism decomposition heat to evaporate the moisture and to disinfect the virus and pathogene fungi.
Abstract translation: 通过使用好氧微生物的分解和增殖，排出牲畜生产设备的牲畜粪便中的有机成分有所消除，其中粪便中的水分被蒸发并且病原体真菌被生物能消毒，导致分解过程中最小化 粪便中氮等营养物质的流失给予有机稗粪。 将牲畜的粪便与锯屑和稻壳混合，将水分控制在65％，通过底部空气给料器曝气将混合物与好氧微生物接触，随后在粪便中分解有机组合物。 通过微生物分解热使反应器中的温度升高，蒸发水分并消毒病毒和病原真菌。
