培菌工业葡萄糖是以优良淀粉或大米经为质料，经淀粉酶液化、葡萄糖酶糖化精制浓缩而成的块状葡萄糖，将块状葡萄糖切削后单调成葡萄糖粉，又称工业糖粉或工业级葡萄糖粉。白色粉状固体，微生物发酵、污水处理等工作。培菌工业葡萄糖是葡萄糖中的一种，它的由来是非常独特的，液体葡萄糖由淀粉不完全酸水解或不完全酶水解制的，淀粉糖浆按DE值的不同可分为高、中、低转化糖浆，习惯上将 DE值为30左右的转化糖浆称为液体葡萄糖，其中DE值4248的液体葡萄糖在工业中用途广，那么在水处理、化工、皮革等工业中应用较大。
The industrial glucose for culturing bacteria is a kind of massive glucose, which is made of fine starch or rice as raw material and refined and concentrated by amylase liquefaction and glucoamylase saccharification. After the massive glucose is cut into glucose powder, it is also called industrial sugar powder or industrial grade glucose powder. White powdery solid, microbial fermentation, sewage treatment, etc. Industrial glucose is a kind of glucose, its origin is very unique, liquid glucose is made by incomplete acid hydrolysis or incomplete enzyme hydrolysis of starch, starch syrup can be divided into high, medium and low conversion syrup according to the different de value, it is customary to use The conversion syrup with DE value of about 30 is called liquid glucose, and the liquid glucose with DE value of 4248 is widely used in industry, so it is widely used in water treatment, chemical industry, leather and other industries.
1、温度：温度是影响整个工艺处置的首要环境要素,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℃,适宜温度在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合温度条件下，使微生物以快的成长速率成长，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 affecting the whole process disposal, 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 fast 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 pH 6.5-7.5, and grow and reproduce in this environment. Their habit scale of pH is 4-10. 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(异化效果)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(同化效果)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. Glucose for wastewater treatment can degrade disordered high molecular substances or high-energy compounds into simple low molecular substances or low-energy compounds through catabolism (dissimilation effect). Glucose for wastewater treatment can release energy; After metabolizing (assimilating effect), the energy and material supplied by catabolism are used to transform into its own cellular material, and the metabolic wastes are excreted 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.
