以水泥混凝土废料,用来处理养猪事业废水中难以生物分解的污染物。在台湾,大多仅以固体分离、厌氧处理、耗氧处理三个阶段来处理养猪废水。并且为减少事业用水量,所以再将处理后的废水用来清洗猪舍。然而,废水中有些成份及堆积物,是难以被微生物所分解的,所以废水回收再利用后,水中的化学需氧量将不断累积。在本研究中使用气相层析质谱仪(GC/MASS)及红外线光谱分析仪(FT-IR)对三个不同处理阶段中的废水进行大量的成份分析,分析结果显示,难以降解的污染物主要是以含苯基的氨基酸为主,并选择将混凝土废料置入废水中来去除这些成份。实验结果显示,难以处理的成份可被混凝土废料有效的去除,亦可将混凝土废料的pH降低至11以下,并可当土壤改良剂使用。
With cement concrete waste, used to deal with pig breeding wastewater difficult to biodegradable pollutants. In Taiwan, most of them only deal with piggery wastewater through solid separation, anaerobic treatment and oxygen-consuming treatment. And to reduce business water consumption, so the treatment of waste water and then used to clean pigsty. However, some of the wastewater components and deposits, are difficult to be decomposed by microorganisms, so the wastewater recycling, the chemical oxygen demand of water will continue to accumulate. In this study, a large number of component analyzes of wastewaters from three different treatment stages were performed using gas chromatography-mass spectrometry (GC / MASS) and infrared spectroscopy (FT-IR). The results showed that the major pollutants that were difficult to degrade were mainly Phenyl-based amino acids are the main, and choose to put concrete waste into the wastewater to remove these ingredients. The experimental results show that the unmanageable ingredients can be effectively removed by concrete wastes and the pH of the concrete wastes can be reduced to below 11 and can be used as soil amendments.
