Anaerobic Sluge Fluidized Bed Technology

Anaerobic Sluge Fluidized Bed Technology

1. Bio-MC external circulation anaerobic reactor
BIO-MC fully mixed anaerobic reactor On the basis of combining the advantages of traditional EGSB and IC reactor, BIO-MC fully mixed anaerobic reactor was successfully developed. The success of this product is based on the optimized flow state mixing and stirring system and the degassing and sedimentation module. The unique biogas stripping and mixing design and flow state optimization arrangement are used to make the muddy water fully mixed. Separation of gas, water and sludge in the case of turbulent water flow. This makes the design more compact and economical. The wastewater to be treated is pumped into the reactor from the bottom of the reactor using an efficient water distribution system, and the wastewater is mixed with the anaerobic sludge in the reactor through the mixing and stirring system. After the biological reaction with the anaerobic bacteria through the sludge bed upwards, the biogas is removed through the degassing module, and the solid-liquid separation of the precipitation system flows to the water outlet pipe. The biogas produced by the anaerobic treatment enters the biogas treatment system through the biogas pipe and pipe at the top of the reactor. In order to achieve a sufficient mixing effect and resist load impact, a circulation mixing system is provided to make the internal muddy water get well mixed.


*Use anaerobic flocculent sludge to avoid the occurrence of sludge calcification and completely solve the calcification problem
* Longer hydraulic retention time to ensure more complete anaerobic removal and higher biogas production;
*Optimized mixing system and sedimentation system to ensure stable operation and better removal effect;


2. Bio-OC external circulation anaerobic reactor
BIO-OC external circulation anaerobic reactor On the basis of combining the advantages of traditional EGSB and IC reactor, BIO-OC external circulation anaerobic reactor was successfully developed. The success of this product is based on the optimized flow mixing system and degassing and sedimentation module. The unique hydraulic mixing and stirring design and flow optimization arrangement are used to make the muddy water fully mixed. The top or external degassing and sedimentation module can be used in the turbulent water flow. Separate gas, water and sludge under dynamic conditions. This makes the design more compact and economical. The wastewater to be treated is pumped into the reactor from the bottom of the reactor using an efficient water distribution system, and the wastewater is mixed with the anaerobic sludge in the reactor through the mixing and stirring system. After the biological reaction with the anaerobic bacteria through the sludge bed upwards, the biogas is removed through the degassing module, and the solid-liquid separation of the precipitation system flows to the water outlet pipe. The biogas produced by the anaerobic treatment enters the biogas treatment system through the biogas pipe and pipe at the top of the reactor. In order to achieve a sufficient mixing effect and resist load impact, a circulation pump is provided, and part of the wastewater is returned from the upper circulation pipe of the reactor through the circulation pump to return the water to the inlet mother pipe. After being uniformly mixed with the raw water, it is then distributed through the water distribution system. Enter the reactor to adjust the ascending flow rate of the reactor.


*Relatively low volume load and optimized degassing and sedimentation system ensure stable operation and better removal effect;
*There are no running parts inside, no maintenance, short start-up time, and simple operation and control;
*Can meet more stringent requirements on odor, sludge yield and purification level;


3. Bio-RC internal circulation anaerobic reactor
BIO-RC internal circulation anaerobic reactor The advantages of BIO-RC internal circulation anaerobic reactor are based on the design of a two-stage three-phase separator. The effect of the internal circulation anaerobic reactor through the internal circulation is like that of China's "Tai Chi", which dissolves the interference of the produced gas on the sludge loss into the reflux stirring energy that disturbs the bottom sludge bed, turning it into a benefit. Inlet water is pumped into the reactor from the bottom of the reactor through an efficient water distribution system and mixed with anaerobic granular sludge in the reactor. In the main treatment zone in the lower part of the reactor, most of the organic matter is converted into methane and carbon dioxide. The biogas is collected by the three-phase separator in the lower part, and the “gas stripping” action generated in this way drives the water flow through the rising pipe to enter the gas-liquid separator at the top of the reactor. The biogas is separated from this separator, and the water flow returns to the bottom of the reactor through the downcomer. Based on this principle: the reactor is named as internal circulation reactor. In the upper finishing area, the wastewater is further treated, the biogas produced here is collected by the upper three-phase separator, and the treated water is discharged from the top of the reactor.

Since the three-phase separator must take into account the gas collection function and weaken the solid-liquid separation function, the internal circulation anaerobic reactor must be used with caution for anaerobic treatment of wastewater that cannot form good granular sludge due to calcification or high salt.


*Widely used in industrial wastewater treatment, stable effluent quality
*Compact, small footprint, automatic adjustment and efficient processing
*Short hydraulic retention time, can operate normally under high load
*There are no moving parts inside and no maintenance is needed
*Can meet more stringent requirements for odor, sludge output and purification level
