1.Mosaic transformation:
Through the implementation of the mud-film composite MBBR process, MBBR can be combined with A2/O, SBR, oxidation ditch, Biolake and the deformation process of the above activated sludge process. This achieves mosaic transformation without the need for new construction and expansion.
Dai Zhigang transformed the CASS process of a sewage treatment plant in Hohhot into the SBR+MBBR process, so that COD, BOD5, NH3-N, and TN can reach the first-level A standard in the biological pond;
Shi Jian will transform the inner ditch of the Auber oxidation ditch into biomedia area with a filling rate of 10%-20%. When the influent TP is 4.67mg/L and the internal reflux ratio is 75%, only the oxidation ditch biological phosphorus removal can meet the first-level A standard. No auxiliary chemical phosphorus removal required;
MBBR transformation can be combined with various pool types, including round, square, long strip, ring groove, etc.
2.Flexible aeration method:
Mainly use perforated tube aeration, and can also be combined with microporous aeration and catenary aeration, without affecting the use of the process.
Li Yuqing carried out the first-level A upgrade transformation of the Chaoyang Wastewater Treatment Plant, combining MBBR with the suspended chain aeration of the original project, and the denitrification rate increased by more than 15% after the transformation.
3.Short project implementation cycle:
Generally, each group of ponds are within 7-14 days, mainly due to the simple construction and installation, and the amount of civil works for MBBR transformation is small or even no. MBBR components are mostly prefabricated and can be installed directly, which can realize continuous water-cutting transformation.
4.Convenient operation and management:
MBBR application implements the concept of inlay, can continue the operation and management experience of the existing operators on the process, and the process has no special maintenance requirements, and the operation and management are simple.
Underground sewage plants have the advantages of good social environmental benefits, low land occupation, and low noise, which is the current development trend of sewage plants.
MBBR can solve the problem of upgrading the underground sewage plant through the follow-up investment of mbbr bio media. Since the original pond can be upgraded and the volume can be increased, there is no need to reserve long-term civil works during construction, which saves the initial investment cost and has both environmental protection and long-term economic benefits.
