This paper introduces the development process of wastewater disposal, it ' s auto control system, the level of nowadays and several new techniques of china and foreign countries. the immanent structure, control rules, main features and design methods of auto control systems in wastewater disposal process are studied in this paper. aiming at four typical parameters, such as temperature, dissolved oxygen, ph and the planes of water, the distributed control system is designed, composed by pc called epigyny computer and scm 8098 called hypogyny computer, and some sensors, shift deliver utensils and related meet orifices of parameters gathering and figures communication
本文介紹了國內外污水處理及其自動控制系統的發展過程、當今水平和提高自動化程度的若干新技術；研究了污水處理自動控制系統的內在結構、控制規律、主要特點和設計方法；選取污水處理中的典型參數溫度、溶解氧、 ph值和液位等為控制對象，設計了以個人計算機為上位機、以8098單片機為下位機，並輔之以傳感器、變送器及相關介面單元所構成的二級集散控制系統（ dcs ） ；介紹了幾個主要程序模塊的設計思路、工作過程，這些程序模塊是：用高級語言visualbasic6 . 0開發的上位機人機交互界面程序、數據處理和圖表輸出程序，用執行效率高的匯編語言開發的下位機數據採集與系統監控程序、上位機與下位機之間的數據通信程序，匯編語言與vb之間的轉接程序，等等。 -
It indicated that not only can spirulina cells grow photoautotrophically and photomixtrotrophically, but also can grow heterotrophically under some specific conditions. light intensity, light quality, temperature, species and concentration of metals, rare earth elements and vitamins, salinity, cell concentration, dissolved oxygen level and magnetic filed etc., all play important roles in photosynthetic performance and cell productivity of spirutina
認為螺旋藻細胞不但能進行光合自養和混合營養生長，而且在某些特定的環境條件下，還能進行異養生長；光照強度、光質、溫度、金屬元素、稀土元素、鹽度、藻體細胞濃度、溶氧水平、維生素、激素和磁場等環境因素對螺旋藻細胞的光合性能和細胞產率都有顯著影響。 -
The results suggested that the dissolved oxygen in fresh grape wine gradually decreased after wine - filling into the barrel and its content in wine reached a steady level three months later, the dissolved oxygen content in wine varied with the liquid depth ( the deeper point in the barrel, the less of the dissolved oxygen content, however, the change trend were the same ), and for the barrels made of different wood materials, there was difference in the dissolved oxygen content in the initial three months during wine storage and such difference disappeared three months later
結果表明，新鮮酒入桶后，酒中的溶解氧逐漸減少， 3個月後達到穩定值；在橡木桶中，距液面深度不同的葡萄酒中的溶解氧含量不同，愈深含量愈低，但溶解氧的變化趨勢一致；在桶貯的初始3個月內，不同板材製作的橡木桶中酒的溶解氧含量有差異， 3個月後趨於一致。 -
The yeast strain 12y - 5 was identified at the species level using two yeast taxonomy systems published by. j. w. kreger - van rij ( 1984 ) [ 24 ] and j. a. barnett ( 1983 ). [ 19 ] in addition, the ability to assimilate several compounds as main sources of carbon and nitrogen was evaluated at the 500ml shake - flask and 3. 7l kfl bioreactor scales. effects of ph, temperature, concentration of dissolved oxygen and utilizable sugar on the growth rate of cells and the rate of the conversion of substrate into biomass were studied
進而用正交試驗法對該酵母生長的培養基配方及影響生長的重要理化因素進行了較為深入的研究，在此基礎上對影響生長的重要理化因素進行了寬范圍的測驗：並以搖瓶最佳的培養條件為基礎，在3 . 7升kfl -生物反應器上進行了放大試驗。 -
