培菌工業(yè)葡萄糖的特點(diǎn)是什么？
來(lái)源：http://www.nttdr.com 日期：2021-03-08 發(fā)布人：admin
培菌工業(yè)葡萄糖是以優(yōu)良淀粉或大米經(jīng)為質(zhì)料，經(jīng)淀粉酶液化、葡萄糖酶糖化精制濃縮而成的塊狀葡萄糖，將塊狀葡萄糖切削后單調(diào)成葡萄糖粉，又稱(chēng)工業(yè)糖粉或工業(yè)級(jí)葡萄糖粉。白色粉狀固體，微生物發(fā)酵、污水處理等工作。培菌工業(yè)葡萄糖是葡萄糖中的一種，它的由來(lái)是非常獨(dú)特的，液體葡萄糖由淀粉不完全酸水解或不完全酶水解制的，淀粉糖漿按DE值的不同可分為高、中、低轉(zhuǎn)化糖漿，習(xí)慣上將 DE值為30左右的轉(zhuǎn)化糖漿稱(chēng)為液體葡萄糖，其中DE值4248的液體葡萄糖在工業(yè)中用途廣，那么在水處理、化工、皮革等工業(yè)中應(yīng)用較大。
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、溫度：溫度是影響整個(gè)工藝處置的首要環(huán)境要素,各種微生物都在特定規(guī)模的溫度內(nèi)成長(zhǎng)。生化處置的溫度規(guī)模在10～40℃,適宜溫度在20～30℃。任何微生物只能在必定溫度規(guī)模內(nèi)生計(jì)，在適合的溫度規(guī)模內(nèi)可很多成長(zhǎng)繁衍。在污泥培育時(shí)，污水處理專(zhuān)用葡萄糖要將它們置于適合溫度條件下，使微生物以快的成長(zhǎng)速率成長(zhǎng)，過(guò)低或過(guò)高的溫度會(huì)使代謝速率緩慢、成長(zhǎng)速率也緩慢，過(guò)高的溫度對(duì)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：微生物的生命活動(dòng)、物質(zhì)代謝與pH值密切相關(guān)。大多數(shù)細(xì)菌、原生動(dòng)物的適pH值為6.5～7.5，在此環(huán)境中成長(zhǎng)繁衍棒，它們對(duì)pH值的習(xí)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(tuán)細(xì)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 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、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(zhuān)用葡萄糖經(jīng)過(guò)分解代謝(異化效果)使雜亂的高分子物質(zhì)或高能化合物降解為簡(jiǎn)略的低分子物質(zhì)或低能化合物，污水處理專(zhuān)用葡萄糖并釋放出能量;經(jīng)過(guò)組成代謝(同化效果)使用分解代謝所供給的能量和物質(zhì)，轉(zhuǎn)化成本身的細(xì)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(wú)機(jī)鹽及成長(zhǎng)要素為微生物成長(zhǎng)的條件。廢水中應(yīng)按BOD5∶N∶P=100∶5∶1的份額彌補(bǔ)氮源、含磷無(wú)機(jī)鹽，污水處理專(zhuān)用葡萄糖為活性污泥的培育發(fā)明杰出的養(yǎng)分條件。
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、懸浮物質(zhì)SS：污水中富含很多的懸浮物,經(jīng)過(guò)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(shí)會(huì)構(gòu)成浮渣層,但不影響體系對(duì)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(xì)菌屬于好氧性的。氧對(duì)好氧微生物有兩個(gè)效果：①在呼吸效果中氧作為結(jié)尾電子受體;②在醇類(lèi)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(chēng)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.
