MBBR一体化生活污水处理设备的工作原理与优缺点
随着大家对环境保护的日趋重视，污水处理设备的需求量也正在越发增多。居民小区、学校、酒店宾馆的生活污水处理设备是比较常见的一种污水处理装置，例如：LYWC-MBBR一体化生活污水处理设备，采用的是MBBR污水处理工艺。那么这种MBBR一体化生活污水处理设备的工作原理是什么呢？沃特桑尼LYWC-MBBR一体化生活污水处理该设备基于生物膜法的基本原理。通过在反应器中加入一定量的悬浮载体，提高了反应器中的生物量和生物种类，从而提高了反应器的处理效率。由于填料的密度与水的密度相近，因此在曝气过程中，填料与水完全混合。微生物生长的环境是气体、液体和固体。载体在水中的碰撞和剪切使气泡变小，提高了氧的利用率。另外，每个载体的内外生物类型不同，一些厌氧菌或兼性菌生长在内部，而外部是好氧菌，因此每个载体都是一个微反应器，使硝化和反硝化同时存在，从而提高了处理效果。上海龙亚提供的沃特桑尼LYWC-MBBR一体化生活污水处理该设备兼有传统流化床和生物接触氧化工艺的优点。它是一种新型高效的污水处理方法。它依靠曝气池内的曝气和水流的提升作用使载体处于流化状态，然后形成悬浮活性污泥和附着生物膜，使移动床生物膜利用整个反应器空间，充分发挥附着相和悬浮相的优势，使它们相互补充。与以往的载体不同，悬浮载体与污水接触频繁、多次，因此被称为“移动生物膜”。

LYWC-MBBR一体化生活污水处理设备的优点：
1、填料由聚乙烯、聚丙烯及其改性材料、聚氨酯泡沫等组成。其比重接近水，主要为圆柱形和球形，易成膜，无结块、无堵塞、易脱膜。
2、良好的脱氮能力：填料上形成好氧、缺氧、厌氧环境。硝化反硝化可以在一个反应器内进行，对氨氮的去除效果较好。
3、结果表明，反应器内污泥浓度高，一般污泥浓度比常规活性污泥法高5～10倍，可达到30～40g/L，提高了有机物的处理效率，抗冲击负荷能力强。
4、维护管理方便：曝气池内无需设置填料支架，池底填料及曝气装置的维护方便，节省投资和占地面积。

LYWC-MBBR一体化生活污水处理设备的缺点
每种设备出来都是其优点与缺点并存，没有一种设备是没有缺点的，那么沃特桑尼LYWC-MBBR一体化生活污水处理设备的缺点是什么呢？沃特桑尼LYWC-MBBR的缺点是反应器中的填料依靠曝气和水流的提升作用处于流化状态，在实际工程中，容易出现局部填料堆积的现象。为了避免填料堆积，应改进曝气管道的布置和反应器的结构。反应堆的结构在很大程度上决定了它的水力特性。在实际工程中，当单个反应器的长高比为0.5左右，长度不超过3m时，有利于填料的完全运动。在实际工程设计中，需要进行大量的试验，以优化反应器的结构和水力特性，降低能耗，进一步提高MBBR的经济效益。但在反应器的出水口往往装有格栅或填料板，以免造成堵塞。
LYWC-MBBR一体化生活污水处理设备可疑故障解决方法：
那么沃特桑尼LYWC-MBBR的缺点导致其可能发生的故障应该怎么解决呢？在实际工程中，可设置活动格栅板，定期进行人工清理，还可设置空气反吹装置，防止堵塞。
好了，以上就是LYWC-MBBR一体化生活污水处理设备的工作原理与优缺点例举，以及可疑故障的解决方法。更多问题，欢迎与上海龙亚污水处理设备技术部探讨交流。
Working principle, advantages and disadvantages of MBBR integrated domestic sewage treatment equipment
With the increasing attention to environmental protection, the demand for sewage treatment equipment is also increasing. Domestic sewage treatment equipment in residential quarters, schools, hotels and hotels is a common sewage treatment device, such as WaterSunny LYWC-MBBR integrated domestic sewage treatment equipment, which adopts MBBR sewage treatment process. So what is the working principle of MBBR integrated domestic sewage treatment equipment? The WaterSunny LYWC-MBBR integrated domestic sewage treatment equipment is based on the basic principle of biofilm process. By adding a certain amount of suspended carrier into the reactor, the biomass and species in the reactor were improved, and the treatment efficiency of the reactor was improved. Since the density of the filler is close to that of the water, the filler is completely mixed with the water during aeration. The environment in which microorganisms grow is gas, liquid and solid. The collision and shear of the carrier in water make the bubble smaller and improve the utilization rate of oxygen. In addition, the internal and external biological types of each carrier are different. Some anaerobic bacteria or facultative bacteria grow in the interior, while the external is aerobic bacteria. Therefore, each carrier is a micro reactor, which makes nitrification and denitrification exist at the same time, thus improving the treatment effect. WaterSunny LYWC-MBBR integrated domestic sewage treatment equipment provided by Shanghai Longya has the advantages of traditional fluidized bed and biological contact oxidation process. It is a new and efficient sewage treatment method. It relies on the aeration in the aeration tank and the lifting effect of water flow to make the carrier in the fluidization state, and then form suspended activated sludge and attached biofilm, so that the moving bed biofilm can make full use of the whole reactor space, give full play to the advantages of attached phase and suspended phase, and make them complement each other. Different from the previous carriers, the suspended carriers contact with wastewater frequently and many times, so it is called "mobile biofilm".
Advantages of WaterSunny LYWC-MBBR integrated domestic sewage treatment equipment:
1. Fillers are composed of polyethylene, polypropylene and its modified materials, polyurethane foam and so on. It is mainly spherical and free from water blocking.
2. Good denitrification capacity: aerobic, anoxic and anaerobic environment is formed on the packing. Nitrification and denitrification can be carried out in one reactor, and the removal effect of ammonia nitrogen is better.
3. The results show that the concentration of sludge in the reactor is high. The concentration of general sludge is 5-10 times higher than that of conventional activated sludge process, which can reach 30-40 g / L. the treatment efficiency of organic matter is improved and the anti shock load capacity is strong.
4. Convenient maintenance and management: there is no need to set packing support in the aeration tank, and the maintenance of the bottom filler and aeration device is convenient, saving investment and floor area.
Disadvantages of WaterSunny LYWC-MBBR integrated domestic sewage treatment equipment
Each kind of equipment has its advantages and disadvantages, and no equipment has no disadvantages. What are the disadvantages of WaterSunny LYWC-MBBR integrated domestic sewage treatment equipment? The disavantage of WaterSunny WaterSunny LYWC-MBBR is that the fillers in the reactor are in fluidization state depending on the lifting effect of aeration and water flow. In practical engineering, the phenomenon of local packing accumulation is easy to occur. In order to avoid packing accumulation, the layout of aeration pipe and the structure of reactor should be improved. The structure of the reactor largely determines its hydraulic characteristics. In practical engineering, when the length to height ratio of a single reactor is about 0.5 and the length is less than 3 m, it is conducive to the complete movement of the filler. In practical engineering design, a lot of tests are needed to optimize the structure and hydraulic characteristics of the reactor, reduce energy consumption and further improve the economic benefits of MBBR. However, the outlet of the reactor is often equipped with grid or filler plate to avoid blockage.
Solution to suspicious fault of WaterSunny LYWC-MBBR integrated domestic sewage treatment equipment:
So how to solve the possible faults caused by the shortcomings of WaterSunny LYWC-MBBR? In the actual project, movable grid plate can be set up for regular manual cleaning, and air back blowing device can be set to prevent blockage.
Well, the above is the working principle of WaterSunny LYWC-MBBR integrated domestic sewage treatment equipment and examples of advantages and disadvantages, as well as solutions to suspicious faults.
