Description

Biological denitrification synergistic treatment device

Technical Field

Background

In recent years, biochemical water treatment, in which contaminated substances in wastewater are changed into harmless substances by utilizing physiological activities of microorganisms, has been widely used in the field of water treatment, particularly in the field of wastewater treatment. Although the activated sludge process is the mainstream as a general biological treatment process, in a general activated sludge process, since it is difficult to increase the concentration of microorganisms in a tank and a high load cannot be obtained, there are problems that a large floor space is required, management of organisms is difficult, treatment performance such as swelling is easily deteriorated, a large-scale sedimentation facility is required, and an amount of waste such as excess sludge is generated in a large amount. As a technique for solving these problems, a method of performing solid-liquid separation of activated sludge by a membrane, a method of performing treatment by attaching microorganisms such as sponge or polymer carrier, and a method of performing treatment by using a pellet, which is a block having a high specific gravity and is formed by granulating itself by microorganisms, have been developed. Among them, the method using the particles is attracting attention because it can hold a large amount of microorganisms in a tank, has a high reaction rate per unit volume, and is easy for solid-liquid separation.

In this case, although organic substances and the like contained in the drainage water can be used as the hydrogen donor, when the hydrogen donor is insufficient, it is necessary to supply the hydrogen donor from the outside. In this case, the hydrogen donor is supplied in an amount determined based on the nitrogen concentration in the wastewater, and is continuously added based on the amount. Among them, in the denitrification treatment for reducing nitrite ions and nitrate ions into nitrogen gas by denitrifying bacteria, there is a method of performing denitrification by adding sponge or gel-like carrier in order to increase the concentration of denitrifying bacteria and facilitate solid-liquid separation, in addition to the activated sludge method. Further, there is a method of performing denitrification by forming a cake having a high specific gravity, that is, a pellet by itself, and significantly increasing the concentration of the denitrifying bacteria in the tank.
