带领大家认识一下水质对葡萄糖培养微生物的影响:
To lead you to understand the impact of water quality on glucose culture microorganisms:
今天的内容是有关污水处理专用葡萄糖培养微生物的水质要求,希望大家可以认真看一下。
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、温度:温度是影响整个水处理专用葡萄糖的首要环境要素,各种微生物都在特定规模的温度内成长。生化处置的温度规模在10~40℃,温度适宜在20~30℃。任何微生物只能在必定温度规模内生计,在适合的温度规模内可很多成长繁衍。在污泥培育时,污水处理专用葡萄糖要将它们置于适宜温度条件下,使微生物以更快的成长速率成长,过低或过高的温度会使代谢速率缓慢、成长速率也缓慢,过高的温度对微生物有致死效果。
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:微生物的生命活动、物质代谢与pH值密切相关。大多数细菌、原生动物的适pH值为6.5~7.5,在此环境中成长繁衍很棒,它们对pH值的习惯规模在4~10。而活性污泥法处置废水的曝气体系中,作为活性污泥的主体,菌胶团细菌在6.5~8.5的pH值条件下可发生较多粘性物质,构成杰出的絮状物。
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、养分物质:废水中的微生物要不断地吸取养分物质,污水处理专用葡萄糖经过分解代谢使杂乱的高分子物质或高能化合物降解为简略的低分子物质或低能化合物,污水处理专用葡萄糖并释放出能量;经过组成代谢使用分解代谢所供给的能量和物质,转化成本身的细胞物质;一起将发生的代谢废物排泄到体外。水、碳源、氮源、无机盐及成长要素为微生物成长的条件。废水中应按BOD5∶N∶P=100∶5∶1的份额弥补氮源、含磷无机盐,污水处理专用葡萄糖为活性污泥的培明杰出的养分条件。
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、悬浮物质SS:污水中富含很多的悬浮物,经过预处置悬浮物已大多数去掉,但也有有些不能降解,曝气时会构成浮渣层,但不影响体系对污水的处置。
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:好养的生化细菌属于好氧性的。氧对好氧微生物有两个效果:①在呼吸效果中氧作为结尾电子受体;②在醇类和不饱和脂肪酸的生物组成中需求氧。且只要溶于水的氧(称溶解氧)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.
