MBR का सुविधाहरू

समय: 2020-04-15 हिट्स: 50

Compared with traditional water treatment methods, MBR has the following obvious features:

1. एमबीआरले प्रभावकारी ढल निकासामा सूक्ष्मजीवहरूलाई पासोमा पार्न सक्छ र फोहोर उमेर र हाइड्रोलिक रिटेन्सन समयको बिभिन्न अनुभव गर्न सक्छ। स्लज युगको आकार समायोजन गरेर, नाइट्रिफाइ with ब्याक्टेरिया र डेनिट्राइफिंग ब्याक्टेरिया जस्ता लामो विकास चक्रको साथ सूक्ष्मजीवहरू पनि प्रभावशाली ब्याक्टेरिया हुन सक्छ, केही हदसम्म सम्पूर्ण रिएक्टरको नाइट्रोजन हटाउने दक्षता सुधार गर्न सकिन्छ, यस कार्यलाई थप लचिलो बनाउँछ। र स्थिर।


2. MBR has high solid-liquid separation efficiency, good and stable effluent effect, and little effect on the quality of influent water. Due to the high-efficiency trapping effect of the membrane, larger particles, organic molecules and bacteria in the reactor are trapped on the water inlet side of the membrane. At the same time, there is no need to consider sludge expansion.


3. The sludge concentration is high and the remaining sludge output is small. MBR can be operated under the conditions of high volume load and low sludge load, and the remaining sludge output is low, which greatly reduces the subsequent treatment costs.


4. The MBR reactor has a compact structure and concentrated process equipment, so it occupies a small area, and it is easy to realize integrated automatic control and convenient operation and management.


Although MBR has the above characteristics, it also has disadvantages, such as serious membrane pollution, low oxygen utilization rate, high investment cost, high energy consumption for water treatment, and chemical cleaning waste liquid will cause secondary pollution. In practical applications, membrane fouling is the biggest limiting factor affecting the promotion of MBR.
