Abstract

PURPOSE:To prevent a filter medium for contact oxidation from clogging and to prevent also from scaling off of microorganisms, by dipping the filter medium having many bristles raised thereon in waste water held at aerobic environment, permitting thus sticking and propagation of aerobic microorganisms on the surface of the filter medium. CONSTITUTION:A filter medium 1 for contact oxidation is formed by raising surfacial fibers of plate base bodies 1 consisting of glass fiber, etc. randomly, and forming bristle parts 2 by reinforcing the raised fibers with a hardening agent. A waste water purifying apparatus is constituted by arranging plural numbers of the filter medium in parallel in each aeration tank 5 utilizing the filter medium as carrier for microorganisms. The waste water is purified in the aeration tank 5 contg. the filter medium 1 having many bristles 2 raised thereon, which provide a large surface area per unit volume of the tank 6. Moreover, the filter medium holds a large amt. of the microorganism but does not cause migration of the microorganisms in the waste water since the medium is constituted of bristles. Thus, scaling off of microorganisms is also prevented.

[Problems to be solved by the invention] Filter media with entangled fibrous materials or spiral media have a large surface area per unit volume of the filter media, which is the core of the microbial membrane formed by the attachment of microorganisms. Can hold large amounts of microorganisms. However, handling is troublesome, the flow of oxygen contained in wastewater and water is poor, dead primary organisms, so-called unnecessary sludge, are not separated, and anaerobic bacteria are likely to grow in some areas. As a result, they often become clogged and partially exhibit a state of putrefaction, which can impede sewage treatment.

[Function] In the filter medium of the present invention, since a large number of bristles are made to stand up from the plate-shaped base, clogging is prevented by the flow of water along the base. Microorganisms adhere to and form on the bristles that stand up from the base, but because they are bristles, they do not move in the water and can retain the microorganisms. Moreover, since it is plate-shaped, it is easy to handle.

Next, the wastewater is sent to the aeration tank 5, where full-scale wastewater purification is performed. Inside the aeration tank 5, a plurality of filter media 1 according to the present invention are arranged in parallel, and oxygen, etc. be supplied with. As explained in FIG. 1, the filter medium of the present invention has a plate-like substrate 1 with countless bristles 2 standing up, and therefore has a large surface area per unit volume and can retain a large amount of aerobic microorganisms. Since the bristles are erect, they do not move freely in the wastewater, and the release of microorganisms is prevented. Furthermore, due to its structure, the filter medium allows drainage to flow well along the substrate, and microorganisms are less likely to die due to lack of oxygen, and clogging is less likely to occur. Furthermore, since it is plate-shaped as a whole,
It is also easy to handle. In this way, the multi-stage aeration tank 5
The wastewater that has been gradually purified is finally discharged through the disinfection tank 6. Although some microorganisms in each type die, the precipitated domestic sludge is discharged and disposed of separately.

As explained above, the biological filter medium of the present invention, such as one in which spiral or fibers are entangled, can retain a large amount of microorganisms, but has good oxygen circulation and is unlikely to become clogged. Moreover, it is easy to handle like a plate-shaped one. In other words, it is an excellent hybrid biological method that combines the special effects of both of the above.

[Effects of the Invention] Since the filter medium of the present invention has a large number of bristles standing up from the plate-shaped base, clogging is prevented by the flow of water along the base. A microbial film is attached and formed on the bristles that stand up from the base, but because they are bristles, they do not move freely in the water, preventing the microorganisms from peeling off, and allowing a large amount of microorganisms to be retained. Moreover, since it is basically plate-shaped, it is easy to handle.
