摘要

本研究針對觀音工業區石化產業中某化學工廠改善廢水系統水質，透過廢水之水質檢驗分析尋找生物難分解有機物，並進行三種實驗驗證此物質是生物難分解有機物，會造成廢水系統負擔，使工廠放流水COD居高無法降低，因此需採取前段分流處理。實驗部份先將廠內廢水系統中兩股生物池廢水，其COD分別為3297ppm及1243ppm，將廢水減壓濃縮使濃度提高，再利用高效液相層析法(HPLC-PDA)及氣相層析質譜法(GC-MS)兩種化學分析方法找出有機物種類；藉由高效液相層析法可瞭解水中有機物質成份比例；從檢測圖譜中：濃縮液於RT2.4分鐘的Peak面積由32.58%變成56.49%可發現此波峰無法藉由生物處理系統降低，再從氣相質譜法中瞭解有機物質化學結構為五甲基哌啶醇；最後藉由生物攝氧率、上流式厭氧模組、生化甲烷產氣試驗三種方式可確認五甲基哌啶醇為廢水中生物難分解有機物。

In this study, a chemical plant in the petrochemical industry of Guanyin Industrial Zone was used to improve the water quality of the wastewater system. The water quality test analysis of the wastewater was used to find the biologically difficult to decompose organic matter, and three experiments were carried out to verify that the material is biologically difficult to decompose organic matter, which will cause a burden on the wastewater system and make the plant The COD of the discharged water cannot be lowered, so it is necessary to take the front-end split treatment. The experimental part firstly used two bio-pool wastewaters in the wastewater system of the plant, and the COD was 3297ppm and 1243ppm respectively. The wastewater was concentrated under reduced pressure to increase the concentration, and then the high performance liquid chromatography (HPLC-PDA) and the gas phase layer were used. Analytical mass spectrometry (GC-MS) two chemical analysis methods to find the species of organic matter; high-performance liquid chromatography to understand the proportion of organic matter in water; from the detection map: the concentration of the concentrate in the Peak area of 2.4 minutes by RT 32.58% became 56.49%. It can be found that this peak cannot be reduced by the biological treatment system, and the chemical structure of the organic substance is known from the gas phase mass spectrometry to be pentamethylpiperidin. Finally, the biological oxygen uptake rate and the upflow anaerobic mode are obtained. Group, biochemical methane gas production test three ways can confirm that pentamethyl piperidinol is biologically difficult to decompose organic matter in wastewater.
