Next, embodiments of the present invention will be described with reference to the drawings.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is an explanatory diagram showing a preferred embodiment of the present invention, in which (1) is a super-immersion for sedimentation and separation of solids by receiving various wastewater such as sewage, feces, and domestic wastewater. In the previous step of the second immersion 1, separation means such as a screen may be interposed.

(2) is an adjustment tank and functions as a buffer tank provided for equalizing the throughput and sending it to the post-process in the case of fluctuations in the amount of drainage.

The drainage is sent from the adjustment tank 2 to the aeration tank 4 by a fixed amount by the raw water pump 3.

In the aeration tank 4, the organic matter is decomposed by the microorganisms in the tank according to the biological treatment.

40 is a blower for supplying aeration air to the aeration tank 4.

The suspension from the aeration tank 4 is separated into sludge and treated water in the final settler 5.

The precipitated sludge is sent to the concentration tank 6 and concentrated or not to be sent directly to the circulating reactor 7.

The circulating reactor 7 is constituted by a first reaction tower 70 and a second reaction tower 71, and the first reaction tower 70 has a charging unit 701 formed by charging a solid filler, and this charging unit The diffuser 702 is provided below the 701. 74 is a circulation pump.

In addition, the second reaction tower 71 has a filling part 71 formed by filling a solid filler.

The first reaction tower 70 and the second reaction tower 71 are configured to be circulated by circulation lines 72 and 73 and a circulation pump 74.

Examples of the solid filler to be filled in the first reaction tower 70 and the second reaction tower 71 may include the following ① to ④.

① Solid filler in the first reaction column: Ferrets mainly containing corrosive substances

Solid filler in the second reaction tower: Pumice containing unstable silica with high activity such as andesite or rhyolite

② Solid filler in the first reaction column: Ferrets mainly containing corrosive substances

Solid filler of the second reaction tower: Pumice containing ferrite containing corrosive as a main component and unstable silica with high activity such as andesite or rhyolite

③ Solid filler of the first reaction tower: Pumice containing unstable silica with high activity such as andesite or pyloric

Solid filler in the second reaction tower: Ferrets mainly containing corrosive substances

④ Solid filler of the first reaction column: Pumice containing ferrite containing corrosive as the main component and unstable silica with high activity such as andesite or rhyolite

Solid filler in the second reaction tower: Ferrets mainly containing corrosive substances

Ferrets containing, as a main component, the corrosives used as the solid filler as described above are commercially available and available, for example, "TOYO-ROZAI (A) -PL" manufactured by Dongyang Bioreactor.

In addition, pumice containing unstable silica having high activity such as andesite or pyloric is also commercially available, and "TOYO-ROZAI (B) -SO" manufactured by Dongyang Bioreactor Co., Ltd. may be mentioned.

In the above-described form, the first and second reaction towers may have a shape of a container body standing in a square or circular shape.

It is preferable to fix the container in the center of the charging section filled with the solid filler, the first reaction column and the second reaction column, and to fill the inside of the container with the solid filler.

The diffuser provided below the charging section not only supplies oxygen but also forms an upward flow.

As a result of using the above-described circulating reactor, the eluting component of the corrosive substance which is a component of the solid filler is eluted in the sludge, and the eluting component of the pumice is also eluted in the sludge. The elution component of the corrosives includes an ingredient having a phenolic exposure group, has antimicrobial properties, and sterilizes decaying bacteria, thereby suppressing the occurrence of odor. The component of pumice is Sirica and these contribute to the activation of living things.

Although one reactor alone is concentrated on corrosive or pumice constituents, the amount of nutrients does not increase evenly, but when circulating sludge between two reactors, both components having phenolic exposure groups and silica are eluted. Both sides have the effect of increasing evenly.

The sludge activated in the above-mentioned circulating reactor may be conveyed to either the adjusting tank 2 or the aeration tank 4, and a part of the sludge may be taken out as a surplus sludge, or dehydration may be performed.

Next, another embodiment of the present invention will be described with reference to FIG. 2.

In FIG. 2, reference numeral 10 denotes a circulating reactor, and is constituted by the first reaction tower 101 and the second reaction tower 102.

In this form, the wastewater is introduced directly into the reactor and processed. In this form, microorganisms need to be reproduced in advance in the reactor, but the solid filler is effective by maintaining a constant concentration of the microorganisms and the number of bacteria. Exert. In particular, the ferret containing the corrosive substance contains a large number of spores of bacillus bacillus, and when they come into contact with the drainage, the bacillus spores germinate and increase the number of bacteria.

The drainage water is introduced into the adjustment tank 100 to adjust the flow rate and the concentration, and is introduced into the first reaction tower 101 by the quantitative amount using the pump 100a.

Subsequently, when the drainage and sludge circulate between the two reactors of the first reaction tower 101 and the second reaction tower 102, the contact time between the drainage and the sludge increases, and the elution component of the sludge increases as in the case of FIG. It has a killing effect and odor control effect.

(11) is a circulation pump.

The drainage treated by the two reactors is subjected to solid-liquid separation in the settling basin 13 to obtain treated water. Although the settled sludge is not shown, it is preferable to be conveyed to either side of the reactor 10.

In FIG. 2, since portions having the same reference numerals as in FIG. 1 have the same configuration, description thereof will be omitted. The solid filler may be the same as that of FIG. 1.

According to the present invention, it is possible to provide a wastewater treatment apparatus which utilizes a plurality of reactors to improve the activation and quality of sludge and further improve the efficacy of the corrosive.
