碩士 === 國立屏東科技大學 === 畜產系 === 94 === Waste water of the meat market for organic matter extremely high waste water, moreover this waste water includes the high fat, in the fat solid thing, the cutting hashed meat of, the leather meal, the wool, the internal organs the tolerant nature, the electricity butchers the process Chinese and foreign to leak the blood, slaughters equipment and slaughter body wash water and so on materials, with the pig only excreta （for example excrement, urine）, the vomitus and the pig only flushes coolly, moors waste water and so on fence flushing and carrier vehicle flushing, however the pig night soil waste water is highly concentrated organic waste water, also nitrogen, phosphorus content proportion high （Yang, 2003）, this research trial location is located in the Bingdong meat marketWaste water processing tank. The experiment divides into the winter and the summer two seasons, Yu Caishui divides into at the same day has slaughters the pig （2 repetitions） with not to slaughter the pig （4 repetitions）, separately in 1200, 1800, 2400 and 0600 these four time intervals in the liquid-solid separating tank, mixes well the pond, initially sinks the pond, the good gas treating pond one, the good gas treating pond two, the good gas treating pond three, the end sinks the pond one, the end sinks the pond two, the end sinks the pond three and the release mouth and so on ten does the water quality sampling analysis research, with sinks the pond backflow sludge pipe in the end, the nitration pond and the concentration basin and so on three does the sludge sampling analysis research. The waste water part altogether examined the water temperature, has dissolved the oxygen, the pH value, leads the kilowatt hour, the nitrate nitrogen, the redox potential, biochemical oxygen demand （BOD）, chemical oxygen demand （COD）, suspended solid thing （SS）, kelvin nitrogen （TKN）, the phosphorus and the ammonia nitrogen and so on 12 projects, the sludge part altogether examines water temperature （TEM）, has dissolved oxygen （DO）, the pH value, leads kilowatt hour （COND）, the nitrate nitrogen （NO3）, redox potential （ORP）, phosphorus （P）, nitrogen （N）, the ammonia nitrogen (NH4), copper （Cu）, zinc （Zn）, calcium （Ca）, potassium （K）, manganese （Mn） and magnesium（Mg） and so on 15 projects. This experimental result when waste water part, summer the water temperature is higher than the winter （p < 0.001）, because the microorganism under the high temperature the vigor increases, but causes metabolism use to speed up is advantageous to the water treatment work, no matter has or not slaughters, is all different in the different pool reaction, biggest lies in differently has slaughters when the organic matter not slaughters when many, the microorganism uses to synthesize metabolism the choice to be many, but leads the kilowatt hour is actually is in the summer lower than the winter （p < 0.001）, because the nitrate nitrogen under the high temperature function the digestion is quick （p < 0.001）, causes the content quite to be also high, when winter the water temperature compares the outside high temperatureHigh and easy to cause in the water the suspended solid thing （SS） outflow, but creates the suspended solid high phenomenon, When the sludge part, the different temperature effect different season with whether there is slaughters, presents the high temperature time to process advantageously (p < 0.01), but the high temperature relative can create dissolves the oxygen the drop, in the summer water temperature when 28.54℃, dissolves the oxygen only then 0.17mg/L，But winter water temperature when 23.99℃, dissolves the oxygen to rise 0.51mg/L，Moreover certain heavy metals also have the ascension phenomenon (for example calcium, magnesium), and certain heavy metals in the summer the condition which is lower than the winter （for example zinc, manganese）, therefore the grasping temperature change will be advantageous to the sludge processing work. Above the synthesis the experimental conclusion is: 1st, high organic load to microorganism temperature influence, when high temperature also high organic load, microorganism handling ability and activeness are not affected. 2nd, along with the water power resident time increase, will cause the processing effect increase. When 3rd, not slaughters, the nitrate nitrogen can receive the season influence. 4th, how much influence can the redox potential receive slaughters quantity, slaughters the quantity to be more can cause the redox potential to change high. 5th, the kelvin nitrogen can lengthen along with the process time reduces. 6th, the chemical oxygen demand and suspended solid Yi Shouzhong sinks the pond bottom putty content influence, but elevates its density. 7th, tires of when the oxygen easy to have the denitrifying also to cause the pH value rise.
