摘要

為處理豬糞尿水中的氮磷，本研究發展出一套包含無氧、厭氧及好氣等單元的系統，同時進行實驗以評估不同有機負荷時此系統的處理效果。
實驗時無氧槽及厭氧槽的溫度控制在攝氏37±1℃，好氣槽則為攝氏30±1℃。進流原廢水的COD濃度調整在約5,000 mg/L，並以系統水力停留時間(HRT)5.75天、3.83天及2.875天為操作參數改變有機負荷，然後觀察整個系統及各槽的固形物、有機物、氮化物及磷化物的變化情形。
實驗結果顯示本系統對豬糞尿水中的COD及氮磷均有顯著的去除效果，COD、總氮及總磷的去除率分別為92~98%，62~93%及42~88%。

A system including units of anoxic, anaerobic and aerobic has been developed in this study to remove nutrients for swine wastewater. Three tests at different organic loading rates were also conducted to evaluate the treatment efficiency for this system.
Both anoxic and anaerobic units were controlled at 37±1℃, while the aerobic unit was controlled at 30±1℃. The influent COD was prepared at a concentration about 5,000 mg/L before feeding. Three different sets of tests at system HRT of 5.75 d, 3.83 d and 2.875 d were operated to evaluate the performance of the whole system and each individual unit. Water quality including solids, organic matters, nitrogen and phosphate were monitored during experiment.
Experimental results showed that all three tests had significant effect in removing both COD and nutrients for swine wastewater. The removal efficiencies of COD, total nitrogen and total phosphate were achieved at the ranges of 92~98%, 62~93% and 42~88%, respectively.
