Mobile Wastewater Treatment Plant For Domestic Sewage Treatment
Process Core-MBBR
The moving bed biofilm reactor (MBBR), is a new type of
high-efficiency reactor between the activated sludge method and the
fixed biofilm method. The filler with a larger specific surface
area in the reactor moves freely in the water due to stirring, and
the sewage passes through the biofilm on the filler and the
activated sludge in the sewage, thereby purifying the sewage.
Advantages: high processing efficiency, strong denitrification ability, strong
impact resistance, simple operation control and simple maintenance.
Disadvantages: The process has poor phosphorus removal effect, requires uniform
aeration to prevent local filler accumulation, and needs to set up
grid plates to prevent fillers from losing with the treated water.
The input cost is higher than the activated sludge method (mainly
the filler cost).
MBBR-Based Process Improvement
The MSC-MBBR process is based on MBBR. By clarifying the functional
positioning of the pre-denitration zone, anaerobic zone, anoxic
zone and aerobic zone, the sludge return system and the layout
structure of the nitrification liquid return system are optimized
to reduce the activated sewage The advantages of mud method and
biological contact oxidation method are fully combined. While
reducing COD, it strengthens the effect of nitrogen and phosphorus
removal.
Under anoxic conditions, the pre-denitration zone fully removes nitrate and oxygen in the incoming sewage and
return sludge, ensuring a strict anaerobic environment in the
anaerobic zone, and greatly improving the efficiency of phosphorus
accumulating bacteria in the anaerobic zone. To ensure that its
phosphorus absorption efficiency in the aerobic tank has been fully
improved, the nitrification liquid is returned to the anoxic tank
to enhance the denitrification capacity of the reactor, and further
realize the efficient removal of nitrogen and phosphorus by the
MSC-MBBR integrated equipment.
