帶領(lǐng)大家認識一下水質(zhì)對葡萄糖培養(yǎng)微生物的影響：
To lead you to understand the impact of water quality on glucose culture microorganisms:
今天的內(nèi)容是有關(guān)污水處理專用葡萄糖培養(yǎng)微生物的水質(zhì)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(huán)境要素，各種微生物都在特定規(guī)模的溫度內(nèi)成長。生化處置的溫度規(guī)模在10～40℃，溫度適宜在20～30℃。任何微生物只能在必定溫度規(guī)模內(nèi)生計，在適合的溫度規(guī)模內(nèi)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(zhì)代謝與pH值密切相關(guān)。大多數(shù)細菌、原生動物的適pH值為6.5～7.5，在此環(huán)境中成長繁衍很棒，它們對pH值的習慣規(guī)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(fā)生較多粘性物質(zhì)，構(gòu)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(yǎng)分物質(zhì)：廢水中的微生物要不斷地吸取養(yǎng)分物質(zhì)，污水處理專用葡萄糖經(jīng)過分解代謝使雜亂的高分子物質(zhì)或高能化合物降解為簡略的低分子物質(zhì)或低能化合物，污水處理專用葡萄糖并釋放出能量；經(jīng)過組成代謝使用分解代謝所供給的能量和物質(zhì)，轉(zhuǎn)化成本身的細胞物質(zhì)；一起將發(fā)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(yīng)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明杰出的養(yǎng)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(zhì)SS：污水中富含很多的懸浮物，經(jīng)過預(yù)處置懸浮物已大多數(shù)去掉，但也有有些不能降解，曝氣時會構(gòu)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(yǎng)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(jié)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.
