| 摘 要： | 针对微污染水源水贫营养和低碳源的特点,利用固定化微生物技术将异养硝化菌(WGX8、WGX18)、好氧反硝化菌(HF3、HF7)固定于自制悬浮纤维海绵球型填料上,研究了贫营养及好氧条件下水源水的生物脱氮过程.试验结果表明,在原水总氮2.7 mg/L、氨氮1.3 mg/L以及控制水温25 ℃、溶解氧3～4 mg/L条件下,经过19 d的连续运行,构建的生物膜系统对水中氨氮的去除率达到了100%,总氮去除率最高达到52%,处理效果稳定.

| Abstract: | According to the characteristics of lower nutrient substances and carbon source in micro-polluted water bodies, the author established a method of immobilizing heterotrotrophic nitrifying bacteria and the aerobic denitrifying bacteria on suspended fiber/sponge spherical packing to strengthen bio-contact oxidation function. The constructed nitrification-denitrification system was employed for the treatment of micro-polluted water under aerobic condition, and the removal of nitrogen was experimentally studied. Experimental results showed that the removal rates of NH+4-N and TN were 100% and 52% respectively after 19 d of operation under the conditions of TN was 2.7 mg/L, NH+4-N was 1.3 mg/L, temperature was 25 ℃ and DO was 3-4 mg/L. The operation of the constructed bio-contact oxidation system kept in stable. |
