Description

Filter structure for sewage treatment of septic tank {A FILTER FOR WASTE WATER TREATMENT}

The present invention relates to a filter for sewage treatment of a septic tank, and more particularly, to prevent environmental pollution by effectively purifying the manure of household sewage generated at home.

In general, if sewage and manure are discharged without treatment, they cause a lot of adverse effects on the water system, which is a serious cause of water pollution.

In particular, detergents, dishwashing detergents, etc. contained in the household sewage have emerged as a serious cause of water pollution.

Such sewage and manure may be treated at the sewage terminal treatment plant, but this is not only difficult to install the sewage terminal treatment plant in residential areas, but also causes additional facilities such as collection lines and heavy facility expenses. A separate septic tank is installed at home to collect and treat manure.

Such a septic tank is simply formed in a form of collecting manure, the incoming manure is settled and the sewage is discharged to the sewer through the discharge pipe, conventionally put a gravel layer and PVC in the discharge pipe to purify the discharged sewage Implemented purification structure.

However, such a conventional purification structure has a relatively low purification efficiency, so that when the sewage and manure are introduced into the septic tank, about 50% of the manure and the sewage are discharged directly to the sewer without being filtered, thereby fundamentally solving the problem of water pollution. There was a problem not to do.

The present invention has been made to solve the problems of the prior art, to improve the purification treatment efficiency in the septic tank by living manure and rainwater flowing in from the home to prevent environmental pollution in advance. Have a purpose

In addition, the present invention has an object of making it easy to apply in a common household at a low cost of equipment according to a simple structure.

1 is a schematic structural diagram of a septic tank employing a filter for sewage treatment of the present invention.

Figure 2 is a perspective view of the structure of the present invention sewage filter.

3 is an enlarged view of a portion A of FIG. 1;

<Explanation of symbols for the main parts of the drawings>

1: Septic tank body 2: Manure inflow pipe

3: sewage discharge pipe 4: sewage filtration filter

5: auxiliary filter

The object is that the inlet side of the discharge port is provided with a sewage filter that is easily removable, the sewage filter can be achieved through the filter structure for sewage treatment of the septic tank, characterized in that the porous paper membrane is provided with a plurality of layers. do.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view showing a septic tank structure in which the filter of the present invention is employed, and on one side of the septic tank main body 1, a manure inflow pipe 2 into which living sewage generated at home is introduced is installed, and on the other side, sewage is drained. Sewage discharge pipe (3) to be discharged to the side is to be installed.

In particular, at the inlet side of the sewage discharge pipe (3) is equipped with a cylindrical sewage filtration filter (4) consisting of a plurality of layers of porous paper film (4 ') is to clean the discharged sewage, the sewage The filtration filter 4 has a perspective view in FIG.

In addition, it is possible to form a double filter structure by selectively installing the auxiliary filter 5 of the porous wool material such as a cloth inside the flow path of the sewage discharge pipe (3).

In the figure, reference numeral 6 denotes an opening and closing lid of the septic tank, and 7 denotes a support cover of the filter.

The effect of the present invention constituting such a filter structure will be described.

That is, the manure having the weight of the living sewage introduced into the septic tank body 1 along the manure inlet pipe 2 sinks under the septic tank, and other sewage is discharged by the sewage discharge pipe 3.

At this time, the sewage discharged to the sewage discharge pipe 3 can be effectively filtered by passing through the paper film 4 'provided in multiple layers in the sewage filtration filter 4 of the present invention in order. On the other hand, in the case where the purified sewage contains a large amount of fine impurities or a component which is not filtered out of the paper film, some of the impurities may not be filtered out by the paper film 4 '. By selectively installing a porous woolen auxiliary filter (5) at the end of the sewage discharge pipe (3) can be purified in two stages. According to the present invention the effective filter structure of the manure More than 80% of the purified water can be discharged to the sewer.

Accordingly, it can be seen that the BOD (Biological Oxygen Demand) value of the effluent can be improved, thereby minimizing the pollution of sewage, rivers and rivers, which are discharge paths of the sewage.

On the other hand, the sewage filtration filter (4) and the optional filter of the secondary filter (5) of the present invention has a structure that is easy to detach, so that the user opens the septic tank opening and closing lid (6) at the required main intervals, and each filter is simply It is possible to maintain the purification efficiency continuously by replacing it.

As described above, the filter structure for sewage treatment according to the present invention is effective to purify sewage by using a paper filter composed of a plurality of layers of porous paper membrane, which is a filter configured for purifying sewage and manure. In addition, when a wool filter is additionally installed on the sewage discharge pipe, the purification process is performed while the sewage passes through the plurality of filters sequentially, thereby further improving the efficiency of the sewage treatment, thereby effectively preventing pollution of the stream. There is an advantage such as keeping the water environment clean.

However, such modified embodiments should not be individually understood from the technical spirit or prospect of the present invention, and such modified embodiments should fall within the attached utility model registration claims of the present invention.

In addition, it is possible to continuously extend the purification efficiency by forming a filter structure that the user can easily remove.
