  1. Putting the potassium permanganate into the filter can improve its effect, the removal of organics and ammonia is increased, the influent concentration can satisfy the water reuse standard. but the turbidity of influent is unsatisfactory. the c / n ratio is the key factor to influence the nitrogen - removal of the anoxic / aerobic two - stage baf when the reflux ratio 、 hydraulic loading and the ratio of gas to liquid in aerobic filter are fixed. the anoxic / aerobic two - stage baf has a good removal of organics at different c / n ratio when the reflux ratio is 2, hydraulic loading is 2. 55m ~ 3 / m ~ 2 ? h and the ratio of gas to liquid in aerobic filter is 3 : 1. the influent concentration of organics is blow 7mg / l. from the beginning to 30cm of the anoxic filter, the removal of the organics is significant ; as the c / n ratio increasing, the influent concentration of ammonia is decreasing. when the c / n ratio is 3. 60, the enfluent concentration of ammonia is 3. 05mg / l which satisfies the water reuse standard. when the c / n ration is less than 3. 60, because of the imperfection

    迴流比為2 : 1 ,水力負荷為2 . 55m3 / m2 ? h ,好氧柱氣水比為3 : 1時試驗表明:不同的c / n ( 1 . 05 7 . 45 )下,兩級曝氣生物濾池對有機物有很好的去除作用,出水有機物濃度小於7mg / l ,其中在缺氧柱進水端30cm內對有機物的去除最為明顯;隨著c / n的增加,系統出水氨氮濃度降低,當c / n為3 . 60時,出水氨氮濃度降到3 . 05mg / l ,已經滿足回用水的氨氮標準; c / n < 3 . 60時,因為缺氧柱的不完全反硝化,體系中硝酸鹽氮和亞硝酸鹽氮發生積累影響了好氧柱的硝化反應使氨氮降解效果較差;系統對總氮的去除隨著c / n的增加而增加,當c / n為3 . 60時,出水總氮已經降到11 . 18mg / l ,滿足回用水的要求。

  3. This thesis introduce the design of dsp control for three phase inverter, witch includes digital realization of pwm control, digital pll, swap control between inverter and utility, and communication with mcu. base on inverter model, inverter output l - c filter is investigated, and double - loop control scheme with tms320lf240 are selected

    本文主要介紹了基於dsp控制三相逆變器系統的總體設計方案,其中包括spwm控制的數字實現、逆變器輸出電壓的數字鎖相、逆變器與旁路間的切換邏輯及逆變器與上位機的通訊。
  4. A combined metabolic mutated strain ( ys - c ) was get by traditional filter method from corynebacterium glutamicum ( ys ). this mutant is threonine auxotrop, aec and ahv resistant, and it can grow in the medium which contants sca as the only source of carbon, and the mutant can endure hight leveal of leu. the mutanted strain can concentrate lysine. the concentration of lysine leveal was 1. 20g / l

    運用傳統育種手段篩選到谷氨酸棒桿ys的多重代謝突變組合菌株ys - c 。該菌株為蘇氨酸營養缺陷型,具有對賴氨酸的結構類似物aec和ahv的抗性,並且能以琥珀酸為唯一碳源生長,能夠耐受高濃度亮氨酸。
