MBBR一體化生活污水處理設備的工作原理與優缺點
隨著大家對環境保護的日趨重視，污水處理設備的需求量也正在越發增多。居民小區、學校、酒店賓館的生活污水處理設備是比較常見的一種污水處理裝置，例如：LYWC-MBBR一體化生活污水處理設備，采用的是MBBR污水處理工藝。那么這種MBBR一體化生活污水處理設備的工作原理是什么呢？沃特桑尼LYWC-MBBR一體化生活污水處理該設備基于生物膜法的基本原理。通過在反應器中加入一定量的懸浮載體，提高了反應器中的生物量和生物種類，從而提高了反應器的處理效率。由于填料的密度與水的密度相近，因此在曝氣過程中，填料與水完全混合。微生物生長的環境是氣體、液體和固體。載體在水中的碰撞和剪切使氣泡變小，提高了氧的利用率。另外，每個載體的內外生物類型不同，一些厭氧菌或兼性菌生長在內部，而外部是好氧菌，因此每個載體都是一個微反應器，使硝化和反硝化同時存在，從而提高了處理效果。上海龍亞提供的沃特桑尼LYWC-MBBR一體化生活污水處理該設備兼有傳統流化床和生物接觸氧化工藝的優點。它是一種新型高效的污水處理方法。它依靠曝氣池內的曝氣和水流的提升作用使載體處于流化狀態，然后形成懸浮活性污泥和附著生物膜，使移動床生物膜利用整個反應器空間，充分發揮附著相和懸浮相的優勢，使它們相互補充。與以往的載體不同，懸浮載體與污水接觸頻繁、多次，因此被稱為“移動生物膜”。

LYWC-MBBR一體化生活污水處理設備的優點：
1、填料由聚乙烯、聚丙烯及其改性材料、聚氨酯泡沫等組成。其比重接近水，主要為圓柱形和球形，易成膜，無結塊、無堵塞、易脫膜。
2、良好的脫氮能力：填料上形成好氧、缺氧、厭氧環境。硝化反硝化可以在一個反應器內進行，對氨氮的去除效果較好。
3、結果表明，反應器內污泥濃度高，一般污泥濃度比常規活性污泥法高5～10倍，可達到30～40g/L，提高了有機物的處理效率，抗沖擊負荷能力強。
4、維護管理方便：曝氣池內無需設置填料支架，池底填料及曝氣裝置的維護方便，節省投資和占地面積。

LYWC-MBBR一體化生活污水處理設備的缺點
每種設備出來都是其優點與缺點并存，沒有一種設備是沒有缺點的，那么沃特桑尼LYWC-MBBR一體化生活污水處理設備的缺點是什么呢？沃特桑尼LYWC-MBBR的缺點是反應器中的填料依靠曝氣和水流的提升作用處于流化狀態，在實際工程中，容易出現局部填料堆積的現象。為了避免填料堆積，應改進曝氣管道的布置和反應器的結構。反應堆的結構在很大程度上決定了它的水力特性。在實際工程中，當單個反應器的長高比為0.5左右，長度不超過3m時，有利于填料的完全運動。在實際工程設計中，需要進行大量的試驗，以優化反應器的結構和水力特性，降低能耗，進一步提高MBBR的經濟效益。但在反應器的出水口往往裝有格柵或填料板，以免造成堵塞。
LYWC-MBBR一體化生活污水處理設備可疑故障解決方法：
那么沃特桑尼LYWC-MBBR的缺點導致其可能發生的故障應該怎么解決呢？在實際工程中，可設置活動格柵板，定期進行人工清理，還可設置空氣反吹裝置，防止堵塞。
好了，以上就是LYWC-MBBR一體化生活污水處理設備的工作原理與優缺點例舉，以及可疑故障的解決方法。更多問題，歡迎與上海龍亞污水處理設備技術部探討交流。
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.
