Abstract
A container-type apparatus for wastewater treatment with a suspended particle system, including one or multiple biological reaction zones. The biological reaction zones can be facultative, anaerobic, anoxic, and aerobic and at least one of the biological reaction zones is a suspended particle system. Particles in the suspended particle system act as the carrier of microbiota and offer better conditions for them to grow. The apparatus adopts a box structure, such as a container type, which is convenient to move, flexible to assemble, and can be used multiple times. Based on actual requirements, this apparatus can also be a structure type. The suspended particle system can increase the concentration of microorganisms significantly, improve the ability to bear impact load, produce less sludge, and without sludge expansion.
