中文摘要 | 本研究之目的乃以桃園灌區生活廢水為對象,調查其水質特性、受季節變化之影響等,並與桃園大圳第二支線上游灌溉水質進行比較。結果顯示,社區生活廢水的各項水質濃度與社區戶數間並沒有一致性存在,而是與社區規劃、社區生活型態有關。其中,若因洗車、花園澆灌水等的稀釋作用較小時,社區生活廢水的化學需氧量約為159~563 mg/L、總氮15~68 mg N/L,及總磷0.6~5.7 mg/L。在季節變化的影響方面,發現生活廢水中pH值乃隨雨季初期→中期→末期而逐漸降低;電導度、生化需氧量、有機氮、凱氏氮,及總氮的平均污染濃度則隨雨季初期→中期→末期的順序而升高;至於化學需氧量、氨氮、硝酸鹽氮、亞硝酸鹽氮,及總磷,是以雨季中期之污染值最高。最後,研究指出,生活廢水水質的污染濃度非常高,其中,電導度是桃園大圳第二支線上游水質的2.2倍,化學需氧量為22.5倍,生化需氧量45.6倍,氨氮2.2倍,有機氮122.4倍,凱氏氮44.0倍,亞硝酸鹽氮2.4倍,總氮14.3倍,及總磷128.3倍。因此,若不慎將生活廢水排入灌溉水道,將嚴重影響灌溉水的品質。 |
英文摘要 | The objectives of this study are to evaluate the water characteristics and season effects of domestic wastewater in Tao-Yuan agricultural zone, Taiwan, for comparison with the irrigation water from upper-stream of the second branch, Tao-Yuan channel. The results showed that the number of community family has no any relationship with the water characteristics of domestic wastewater at all, and the primary factors of influence are the personal and community life pattern. When the dilution effects of washing cars and garden watering are negligible, the chemical oxygen demand of domestic wastewater is approximately 159-563 mg/L, total nitrogen is 15~68 mg N/L, and total phosphorus is 0.6-5.7 mg/L. The pH values of domestic wastewater decreased gradually from beginning to the wet season. The mean concentrations of conductivity, biochemical oxygen demand, organic nitrogen, total kjeldahl nitrogen, and total nitrogen also deteriorated in order from initial part of the wet season to its final part. In addition, the highest concentrations contaminated of chemical oxygen demand, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, and total phosphorus occurred on the middle-wet season. Finally, this study indicated that the polluted concentrations of domestic wastewater are very high. Among others, conductivity is about 2.2 times that of the irrigation water from upper-stream of the second branch, Tao-Yuan channel, chemical oxygen demand is 22.5 times, and biochemical oxygen demand is 45.6 times. The others are ammonia nitrogen 2.2 times, organic nitrogen 122.4 times, total kjeldahl nitrogen 44.0 times, nitrite nitrogen 2.4 times, total nitrogen 14.3 times, and total phosphorus 128.3 times, respectively. Consequently, carelessly discharging the domestic wastewater into agricultural irrigation channel, significantly caused the water quality degradation of irrigation water. |
