Problems solved by technology

Therefore, it is very difficult to form the anaerobic conditions necessary for denitrification, and anaerobic conditions play an important role in denitrification, so the removal efficiency of nitrogen decreases

Abstract

The invention provides a device, which uses processing soil layers and penetrating filter medium layers to purify river water, and a method thereof. The river water purifying device comprises alternatively stacked processing soil layers and penetrating filter medium layers Each processing soil layer comprises a plurality of isolated unit soil layers. A predetermined amount of river water is stored, the river water is supplied to a storing part, which is arranged in the upper end of a nitric acid soil layer, in each soil layer; each penetrating filter medium layer has a stronger hydraulic conductivity, compared with the processing soil layers; the river water purifying device has the advantages that the amount of processed river water is increased; anaerobic conditions are formed stably inspite of the water penetrating coefficient of the soil; and nitrogen, phosphor, and nutritive salt s are removed effectively.

Description

Technical field: [0001] The present invention relates to a device and method for purifying river water by using a treatment soil layer and a permeable filter medium layer, more particularly, to a river water purification device using a treatment soil layer and a permeable filter layer that can increase the treatment flux of river water and method to efficiently remove nitrogen, phosphorus and nutrients by stably forming anaerobic conditions regardless of the hydraulic conductivity of the soil. Background technique: [0002] Traditional river improvement based on dikes leads to river regulation and damage to the river environment, which shortens the residence time of the river and reduces the self-purification capacity of the river. Since river pollution is characterized by large volumes of water and low levels of pollution, it is not practical to apply sewage treatment processes to the entire volume of a river from an economical point of view. Therefore, there is a need for...
