Equipment overview:

Anaerobic biological treatment of wastewater is an important technology in environmental engineering and energy engineering. It is one of the powerful treatment methods for organic wastewater. In the past, it was mainly used for the treatment of sludge, organic waste and part of high concentration organic wastewater in urban sewage plants. In the form of buildings, ordinary digesters were mainly used. Due to the shortcomings of long hydraulic retention time and low organic load, its application in wastewater treatment was limited for a long time, Since the 1970s, the energy shortage in the world has become increasingly prominent. The anaerobic technology of wastewater that can produce energy has been paid attention to. The research and practice have been deepened continuously. A variety of new processes and equipment have been developed, which has greatly improved the holding of activated sludge in the anaerobic reactor, greatly shortening the treatment time and improving the efficiency.

Equipment advantages:

● Wide application range

● Low energy consumption

● High load

● Less excess sludge

● Less nitrogen and phosphorus nutrient requirements

● Anaerobic treatment process has certain bactericidal effect, which can kill parasites, viruses, etc. in wastewater and sewage

● Anaerobic activated sludge can be stored for a long time, and anaerobic reactors can be operated seasonally or intermittently.

Scope of application:

● Organic sludge treatment

● High concentration organic wastewater

● Medium and low concentration organic wastewater

● Urban wastewater treatment
