The present invention relates to an improved contact aeration manure septic tank for manure treatment of manure discharged from a flush toilet, and in particular, organic substances contained in the discharged manure and dilution water are stabilized by aerobic microorganism growth and cell synthesis. The present invention relates to an improved contact aeration type manure septic tank capable of effectively removing the purification efficiency.

In general, contact aeration septic tanks usually consist of a settling chamber, an aeration chamber and a final settling chamber.

For example, Japanese Patent Laid-Open Publication No. 55-5724 and Korean Patent Application No. 91-14500, and the like, the organic material in the process of the sewage flowed into the septic tank sedimentation and first passing through the aeration chamber After disassembling, it has a structure that can be discharged through the final settling chamber.

However, in such a structure, effective purification was not actually expected because the media composed of the aeration chamber or the final sedimentation chamber had a simple intervening structure that could only be flowed by the inflowing manure.

The present invention has been devised to solve the above-mentioned general defects, and can improve the decomposition efficiency of organic substances and increase the adaptability by impact load by the structure that can maintain the microbial concentration of the aeration tank at high concentration. The purpose is to provide an improved contact aeration type manure septic tank.

In other words, the present invention is a decay chamber for sedimenting and decomposing sand and other contaminants contained in the processing object, aerobic microorganisms present in a large amount in the contact medium by continuously supplying air to the processing material through the corruption chamber The contact aeration chamber which promotes decomposition of organic substances by metabolism of the substance, and the sedimentation chamber which separates the processed matter through this contact aeration chamber into microorganisms and treated water, are arranged in the aeration chamber well, By installing a contact media device that can be prevented to exhibit an effective and smooth purification performance in a stable state.

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

1 is a plan view of an improved contact aeration type manure septic tank according to the present invention, and FIG. 2 is a front view of an improved contact aeration type manure septic tank according to the present invention, and FIGS. 3 to 5 are views of the present invention. It is explanatory drawing which showed the structure of the contact medium apparatus part by this.

As shown, the manure purification tank body 1 of the present invention has a basic structure composed of a decay chamber 2, a contact aeration chamber 3, and a precipitation chamber 4.

The decaying chamber (2) is the first settled and anaerobic decomposition of the sand or contaminants and sedimentable solids contained in the inflowed to-be-processed object to make an appropriate organic material loading rate in the contact aeration chamber (3), the precipitated solids The first hydrolysis has a configuration that can be actively performed.

In the decay chamber (2) there is an inlet pipe (5) formed at right angles to facilitate the smooth sedimentation of the inflow of the processing object, and at the end of the decay chamber (2), the smooth transfer of the object to be precipitated and the scum formed in the upper layer Aeration chamber inlet pipe (6) is installed to prevent the inflow of (Scum), the upper part of the manhole (13) and the inspection port (12) for checking the cleaning and processing state of the gas and the width generated therein An air outlet 11 for discharging excess air generated in the gas chamber 3 is provided.

That is, when the object to be processed via the decay chamber (2) is transferred to the contact aeration chamber (3), the microorganisms that adhere to the contact medium (81) of the contact media device unit (8) at a high concentration are diffused. By continuously supplying oxygen to the structure to decompose the organic material. In particular, the arrangement configuration of the contact medium 81 is most important, it is configured to be fixed in a well-organized state so that the microorganisms can be more effectively fixed and a large amount of microorganisms inhabit.

The contact medium 81 is configured to be installed at a right angle with the diffuser (7) has a structure that does not interfere with the flow of water, it is connected to the fitting means by the mounting guide rod 82 can be prevented stepless flow It is configured to maintain an extremely stable state.

The contact filter 81 is preferably configured to ensure the maximum concentration of microorganisms by adopting a circular filter having a large specific surface area, in the longitudinal direction as shown in FIG. 3 and FIG. And it may be installed in the transverse direction.

Referring to the effect of the present invention with such a configuration as follows.

The manure (treatment) introduced into the decay chamber (2) through the inlet pipe (5) is decomposed with time, the sediment object (minutes) is settled, and various organic substances and urine aeration chamber inlet pipe (6 It is supplied to the contact aeration chamber (3) through.

The to-be-processed object naturally supplied to the contact aeration chamber 3 is processed by microorganisms attached to and grown on the contact media (81, 81 ') in the course of passing through the contact media device (8). The contact media (81) (81 ') is configured to be installed in a stable state without flow, and the treatment efficiency can be maximized by the combined action of the smooth oxygen supply by the diffuser (7).

The to-be-processed object via the said contact aeration chamber 3 is conveyed to the precipitation chamber 4 through the part opened in the lower part of the precipitation chamber partition wall 9. The transferred material contains some microorganisms that have been removed from the treated water and the media. In the settling chamber (4), the microorganisms forming the flock are separated from the treated water by gravity and returned 100% to the contact aeration chamber (3) through the opening at the bottom of the settling chamber dividing wall (9). Participate in the decomposition of organic matter.

The treated water separated from the settling chamber 4 becomes treated water containing a small amount of organic material and is discharged through the outlet pipe 10.

As described above, according to the improved contact aeration type manure purifying tank of the present invention, the contact mediator unit 8 is installed in the contact aeration chamber 3 formed between the decay chamber and the precipitation chamber, and the contact mediator unit ( 8) The contact media (81) and (81 ') constituting the insert is inserted and inserted by the mounting guide rod (82) so that the stepless flow is prevented in advance and is configured to maintain an extremely stable state of the purification efficiency There are advantages such as maximum maximization.
