Detailed Description of the Invention The present invention relates to a septic tank filler, in particular, a septic tank filler using a microbial metabolite or corrosive containing a phenol and / or a compound with a phenol exposure when treating wastewater containing organic matter. In order to prevent pollution, many septic tanks for treating wastewater such as household wastewater and livestock wastewater are installed.

In lead and conventional septic tanks, a septic purification method based on an activated sludge method, which aims to decompose organic matter in waste water, to make it low molecular and gas, is adopted.

In such a septic tank, there is a basic problem that sufficient odor removal ability is scarce and odor is generated.

In order to solve these problems, physicochemical reaction between organic substances and microbial metabolites in wastewater promotes macromolecularization including binding, granulation, melting, condensation and polymerization, and enlarging the micro sludge and solid-liquid separation of the odor. It is possible to clean up the waste water easily without the occurrence of.

[Problem solving invention]

In the presence of phenol and phenol-exposed compounds in the metabolites, which facilitate the extraction of microbial metabolites with phenol and phenol-exposed groups.

As a result, wastewater treatment can be efficiently performed because maintenance and promotion of the wastewater treatment function are achieved.

In addition, according to a method in which a filling layer filled with a filler such as phenol is fixed to a portion of the tank in contact with the wastewater in advance, the filling layer may be closed by a sludge or the like within a short time.

Therefore, when the filling layer is closed, the contact between aerobic bacteria and aerobic bacteria and phenol may not be achieved smoothly, so that the breeding of aerobic and aerobic bacteria may not be easily performed. You should do it relatively often.

It is an object of the present invention to provide a septic tank filler which can prevent the closure of the filling layer filled with phenol and the like in a relatively short time and can effectively maintain contact between aerobic bacteria and breathable anaerobic bacteria with electric fillers for a long time. Can be.

[Means for solving the problem]

The possibility of closing in a relatively short time due to sludge of the filling body of the septic tank can be prevented by the septic tank filling body of the present invention having the following configuration.

That is, the present invention is a plurality of fillers that are installed without being fixed to the site in contact with the waste water in the septic tank, a part of the back filler is filled with a microbial metabolite or corrosive including a compound having a phenol and phenol exposure group At the same time the buoyancy adjustment unit is a filling tank for septic tank characterized in that the generated.

In the present invention, the sedimentation properties of the sludge in the septic tank is extremely low if the filler filled with the electric microorganism metabolites or corrosives and the filler filled with the crushed stone containing activated silicic acid such as andesite and rhyolite are used. Good and solid-liquid separation is easy.

In addition, when a plurality of fillers are mixed with suspended flotation or sedimenting fillers in the wastewater, the fillers are easily moved according to the movement of the wastewater, thereby further preventing the closure of the fillers.

In addition, in this invention, "a compound with a phenol exposure group" refers to all the valuables which have a phenol exposure group, and the enzyme which has a phenol exposure group is especially effective.

In addition, "activated silicic acid powder" refers to an unstable substance having high activity, such as volcanic glass, which has a composition of andesite or luteum rock.

[Action]

According to the present invention, organic matter is macromolecules in waste water by contact with microbial metabolites including phenol and compounds containing phenol exposure and precipitate as sludge in a septic tank. This sludge has relatively good sedimentation properties and does not adhere to deposit doors on the surface of the filler.
