Building upon the foundation of the Sequencing Batch Reactor (SBR) process, a wastewater treatment technology—along with its equipment—has been developed to effectively address and overcome the numerous limitations inherent in the standard SBR method. This technology is broadly applicable to the construction of various types of wastewater treatment plants. The operational principle of this integrated treatment system is predicated on a synergistic approach that organically combines the activated sludge microbial method with the biofilm biological method to achieve biochemical wastewater treatment. Within this treatment process, a substantial population of microorganisms proliferates on both fixed and suspended biological carriers, forming a robust biofilm. The dynamic agitation generated by the flow of water and air within the wastewater facilitates the continuous renewal of both suspended microbial flora and the attached biofilm. Furthermore, during the aeration phase, the utilization of these biological carriers significantly enhances the contact efficiency between the microorganisms and the pollutants and dissolved oxygen present in the wastewater. The sequential cycling through anaerobic, anoxic, and aerobic environmental conditions—facilitated by the integrated treatment equipment—bolsters the wastewater purification capabilities of diverse microbial communities, thereby intensifying the removal of organic matter as well as the efficiency of nitrogen and phosphorus elimination.
