帶領大家認識一下水質對葡萄糖培養微生物的影響：
To lead you to understand the impact of water quality on glucose culture microorganisms:
今天的內容是有關污水處理專用葡萄糖培養微生物的水質要求，希望大家可以認真看一下。
Today's content is about the water quality requirements of glucose culture microorganism for sewage treatment. I hope you can take a serious look.
1、溫度：溫度是影響整個水處理專用葡萄糖的首要環境要素，各種微生物都在特定規模的溫度內成長。生化處置的溫度規模在10～40℃，溫度適宜在20～30℃。任何微生物只能在必定溫度規模內生計，在適合的溫度規模內可很多成長繁衍。在污泥培育時，污水處理專用葡萄糖要將它們置于適宜溫度條件下，使微生物以更快的成長速率成長，過低或過高的溫度會使代謝速率緩慢、成長速率也緩慢，過高的溫度對微生物有致死效果。
1. Temperature: temperature is the primary environmental factor that affects the whole water treatment special glucose, and all kinds of microorganisms grow at a specific temperature. The temperature scale of biochemical treatment is 10 ~ 40 ℃, and the suitable temperature is 20 ~ 30 ℃. Any microorganism can only survive in a certain temperature scale, and can grow and multiply in a suitable temperature scale. During the cultivation of sludge, the special glucose for sewage treatment should be placed under suitable temperature conditions to make the microorganism grow at a faster growth rate. Too low or too high temperature will make the metabolism rate slow and the growth rate slow. Too high temperature has a lethal effect on the microorganism.
2、pH值：微生物的生命活動、物質代謝與pH值密切相關。大多數細菌、原生動物的適pH值為6.5～7.5，在此環境中成長繁衍很棒，它們對pH值的習慣規模在4～10。而活性污泥法處置廢水的曝氣體系中，作為活性污泥的主體，菌膠團細菌在6.5～8.5的pH值條件下可發生較多粘性物質，構成杰出的絮狀物。
2. PH value: the life activities and material metabolism of microorganisms are closely related to pH value. Most bacteria and protozoa have a pH value of 6.5-7.5, which is a good environment for growth and reproduction. Their pH habit ranges from 4 to 10. In the aeration system of wastewater treatment by activated sludge process, as the main body of activated sludge, bacteria micelles can produce more viscous substances and form outstanding flocs at pH value of 6.5-8.5.
3、養分物質：廢水中的微生物要不斷地吸取養分物質，污水處理專用葡萄糖經過分解代謝使雜亂的高分子物質或高能化合物降解為簡略的低分子物質或低能化合物，污水處理專用葡萄糖并釋放出能量；經過組成代謝使用分解代謝所供給的能量和物質，轉化成本身的細胞物質；一起將發生的代謝廢物排泄到體外。水、碳源、氮源、無機鹽及成長要素為微生物成長的條件。廢水中應按BOD5∶N∶P=100∶5∶1的份額彌補氮源、含磷無機鹽，污水處理專用葡萄糖為活性污泥的培育發明杰出的養分條件。
3. Nutrient substances: microorganisms in wastewater should continuously absorb nutrient substances. Through catabolism, special glucose for wastewater treatment can degrade disordered high molecular substances or high-energy compounds into simple low molecular substances or low-energy compounds. Special glucose for wastewater treatment can release energy. Energy and substances supplied by catabolism can be converted into its own energy through constituent metabolism Cell substances; excrete metabolic wastes to the body together. Water, carbon source, nitrogen source, inorganic salt and growth factors are the conditions for microbial growth. The proportion of BOD5 ∶ n ∶ P = 100 ∶ 5 ∶ 1 should be used to make up for the nitrogen source and phosphorus containing inorganic salt in the wastewater. Glucose for wastewater treatment is an excellent nutrient condition for the cultivation of activated sludge.
4、懸浮物質SS：污水中富含很多的懸浮物，經過預處置懸浮物已大多數去掉，但也有有些不能降解，曝氣時會構成浮渣層，但不影響體系對污水的處置。
4. SS: there are a lot of suspended substances in the sewage. After pretreatment, most of the suspended substances have been removed, but some of them can not be degraded. The aeration will form a scum layer, but it will not affect the sewage disposal of the system.
5、溶解氧量DO：好養的生化細菌屬于好氧性的。氧對好氧微生物有兩個效果：①在呼吸效果中氧作為結尾電子受體；②在醇類和不飽和脂肪酸的生物組成中需求氧。且只要溶于水的氧（稱溶解氧）微生物才干使用。
5. Do: aerobic biochemical bacteria are aerobic. There are two effects of oxygen on aerobic microorganisms: 1) oxygen is the end electron acceptor in respiration; 2) oxygen is required in the biological composition of alcohols and unsaturated fatty acids. And as long as the dissolved oxygen in water (called dissolved oxygen) can be used by microorganisms.
