大家都知道葡萄糖根据含量和纯度的不同分为食品葡萄糖和工业葡萄糖,当我们做食品添加剂或者食用的时候需要使用的是食品葡萄糖,对葡萄糖要求没有那么高工业用的话就选择工业葡萄糖。食品葡萄糖可以补充我们身体所需的能量物质,而工业葡萄糖同样可以补充污水处理中所需的养分。随着我国污水厂规模的日益加大,污水处理厂每天污水处理量不断的上涨,工业葡萄糖用量这几年也是不断的上涨。今天我们无水葡萄糖厂家就来讲解下污水处理为什么要添加工业葡萄糖?
We all know that glucose can be divided into food glucose and industrial glucose according to the content and purity. When we are making food additives or eating, we need to use food glucose. If the requirements for glucose are not so high, industrial glucose should be selected. Food glucose can supplement the energy needed by our body, while industrial glucose can also supplement nutrients needed in sewage treatment. With the increasing scale of sewage treatment plants in China, the daily sewage treatment capacity of sewage treatment plants is increasing, and the industrial glucose consumption is also rising in recent years. Today, we anhydrous glucose manufacturers will explain why industrial glucose should be added to wastewater treatment?

工业葡萄糖应用于生活饮用水,工业用水,生活用水,生活污水和工业污水处理,工业葡萄糖对生活饮用水及各种工业用水净化处理有着明显的效果。污水处理调试期间投加工业葡萄糖等是为了提供碳源,这是为了更好的培养细菌,提高污水的可生化性。污水处理中作为污泥营养源,比尿素来得快,若运行的系统中COD、BOD不足以供给菌种生长繁殖的话,就需要另外投加,以防污泥老化,生物活性降低。生化池在运行过程中,当微生物一旦受到负荷(水量、浓度)的冲击,COD去除率会突然下降,严重时污泥会从生物填料上脱落,使出水变混。这时应立即停止进水,往生化池内投放污水处理专用葡萄糖以降低污泥负荷,当污泥的沉降性能有所恢复后,可采取污泥驯化的快速增殖法,在生化池内投加生活污水或投放废酒精或用干面粉烧熟的湿浆糊,投加污水处理专用葡萄糖,2-3天后开始进水并逐日增加进水量,直到微生物恢复正常。
Industrial glucose is used in drinking water, industrial water, domestic water, domestic sewage and industrial sewage treatment. Industrial glucose has obvious effect on the purification of drinking water and various industrial water. During the commissioning of sewage treatment, industrial glucose is added to provide carbon source, which is to better cultivate bacteria and improve the biodegradability of sewage. As a nutrient source of sludge in sewage treatment, it is faster than urea. If COD and BOD in the running system are not enough for the growth and reproduction of bacteria, additional dosing is needed to prevent sludge aging and reduce biological activity. During the operation of biochemical tank, once the microorganism is impacted by the load (water quantity and concentration), the COD removal rate will drop suddenly, and the sludge will fall off from the biological filler and make the effluent mixed. At this time, the influent water should be stopped immediately, and the special glucose for sewage treatment should be put into the biochemical tank to reduce the sludge load. When the sedimentation performance of the sludge has been restored, the rapid multiplication method of sludge domestication can be adopted. Domestic sewage or waste alcohol or wet slurry cooked with dry flour powder are added into the biochemical tank, and the special glucose for sewage treatment is added. After 2-3 days, the water will start to flow and increase daily Amount of water until the microorganism returns to normal.
工业葡萄糖一般加在厌氧和好氧系统里。就厌氧而言,主要考虑因素为酸化程度,进水COD,反应在指标上即PH,VFA,COD。COD一般不用考虑,这在均质池(综合调节池)就可以调节的。PH较高,酸化不充分的情况下一般是需要加葡萄糖促进酸化。要根据进水水质情况来决定加多少。一般是加在进生化池前,用水溶解后加入。好氧而言,在不缺少BOD的情况下是不需要加的,缺少的话就要加了,因为缺少BOD的情况下,容易会产生硝化。
Industrial glucose is generally added to anaerobic and aerobic systems. In terms of anaerobic, the main factors to be considered are acidification degree, influent cod, and the reaction indexes are pH, VFA and cod. Generally, COD need not be considered, which can be adjusted in the homogenization tank (comprehensive regulating tank). When pH is high and acidification is not enough, glucose is needed to promote acidification. How much should be added depends on the quality of the influent water. It is usually added before entering the biochemical tank and dissolved in water. In terms of aerobic, there is no need to add BOD in case of lack of BOD. If it is lack of BOD, it is easy to produce nitrification.
