Estimating the term…
The present disclosure provides a container-type apparatus for wastewater treatment with a suspended particle system, including one or multiple biological reaction zones. Said biological reaction zones can be facultative, anaerobic, anoxic, and aerobic and at least one of said biological reaction zones is a suspended particle system. Particles in said 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 for multiple times. Based on actual requirements, this apparatus can also be a structure type. The suspended particle system disclosed herein applied in wastewater treatment can increase the concentration of microorganisms significantly, improve the ability to bear impact load, produce less sludge, and without sludge expansion. Meanwhile, the means to suspend particles by gas and liquid is able to reduce energy consumption to a larger extent. Therefore, this system features high efficiency and low energy consumption.
A container-type apparatus for wastewater treatment with a suspended particle system, comprising one or more biological reaction zones, said biological reaction zones including any one of the facultative zones, anaerobic zone, anoxic zone, and aerobic zone or their combination, and one of said biological reaction zones including a suspended particle system comprised of any one or combination of light particles and heavy particles, said light particles having microorganisms located on their surfaces, a density of said light particles being lower than a density of the wastewater phase, a density of said heavy particles is higher than the density of said wastewater.
