Apparatus for treating waste water using iron oxide powder |
| abstract |
The present invention relates to a water treatment device using powdered iron oxide that treats sewage or wastewater using powdered iron oxide. and a sludge treatment unit for recovering the powdered iron oxide contained in the sludge for reuse in the water treatment unit. Therefore, the present invention improves the sedimentation property primarily by increasing the contact between the microbial floc and the powdered iron oxide by injecting powdered iron oxide, and increases the integration and treatment efficiency in the sewage and wastewater treatment system according to the increase in the amount of microorganisms in the sludge returned from the settling pond It provides an effect that can achieve |
