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.
