術であると報告されている。Conventionally, chemical neutralization methods, aeration methods, adsorption methods, and the like are known as wastewater purification methods for purifying this type of wastewater. The chemical neutralization method has the problems of high running costs due to the daily use of chemicals, and increased disposal costs due to the increased amount of sludge. Aeration treatment is a method of forcibly supplying a large amount of air into wastewater to gasify pollutants suspended or dissolved in wastewater, promote decomposition by microorganisms, and remove the resulting sludge. However, since the reaction is slow, it is necessary to provide a large space for aeration treatment. In particular, for wastewater containing oil and fat, aeration causes the wastewater to foam and lack sufficient agitation, leading to biochemical oxygen demand ffi.
There is a problem in that it is difficult to lower both (BOD) and chemical oxygen demand fi (Con). The method of adsorbing and removing pollutants from wastewater using activated carbon is an effective method because the micropores of activated carbon have a high adsorption capacity, but the micropores may become clogged with the adsorbed pollutants. When this happens, the tray will have to be replaced because it will no longer attract. As is well known, activated carbon is quite expensive, so it is not only cost-effective to replace it frequently (but there is also the problem that wastewater cannot be treated when replacing it. Same as expensive activated carbon. A technology that can obtain this effect at low cost is proposed in Japanese Patent Publication No. 55-22409.In other words, if low-grade coal is used as a raw material and it is made porous by pickling, it can be used as activated carbon. Similarly, it is disclosed that wastewater is purified because pollutants in the wastewater are adsorbed by the micropores.In particular, by making porous activated coal into a fine powder of 160 to 200 mesos. It has been reported that this is an effective technology for removing crude oil suspended on the water surface because it can be suspended on the water surface for a while.

When the activated coal proposed in the publication is first installed in wastewater, it adsorbs pollutants well in its micropores, and is highly effective in purifying wastewater. However, there is a drawback in that the numerous micropores absorb and accumulate pollutants in the wastewater over time, and eventually lose their purifying effect. The present invention aims to provide a wastewater purification material that uses numerous micropores with excellent adsorption ability and can maintain the excellent purification effect initially installed over a long period of time.

して配設される。Porous hybrid char, which is a component of wastewater purification materials, is produced by immersing low-grade coal such as lignite or brown coal in an acid such as sulfuric acid for an appropriate period of time, for example 24 hours, to erode and remove the ash content. It can be made by forming countless micropores inside. The porosity of the hybrid char is preferably approximately 500 to 1000//g. The porosity is 500y! /g or less, the ability to adsorb pollutants in wastewater decreases, and the amount of transferred microorganisms becomes insufficient, resulting in an insufficient purification function of wastewater. On the other hand, a hybrid char with a porosity of 1000+//g or more lacks strength and becomes brittle, so there is a problem that it tends to collapse when stacked in two or three tiers. Therefore, the porosity of hybrid char is 500.
It is preferable that it is in the range of ~10001.117g. The woody part of hybrid char is a nutrient for microorganisms. The wood content is 0.1% so that the microorganisms can live for at least several months during the period until they are transferred and installed in the wastewater, and in case the wastewater that serves as food for the microorganisms is not supplied for a long period after installation. It is preferable that there be more than one. On the other hand, if the woody part is reduced to 10%, the strength of the hybrid char is insufficient and it becomes easy to collapse when stacked in two or three tiers. For this reason, the woody part of hybrid char is 0.
1iTh range of 1% to 10%) is childish. When the sludge material in the wastewater to be purified is oil and fat, the microorganisms that are transferred to the hybrid char include facultative anaerobic microorganisms that can digest and decompose the oil and fat (for example, the microorganism TBG-0001-0001 shown in Figure 3). (September 27, 1988, request for certification from Microtechnical Research Institute); when non-M1 fat content, rhizopods;
Aerobic microorganisms such as flagellates and ciliates are preferred. In the present invention, by analyzing pollutants in wastewater,
Since suitable microorganisms are transferred to the hybrid char in each step, the microorganisms are not specified. These microorganisms are usually cultured by transferring one type of microorganism to one hybrid char. It depends on the type of microorganisms, but if you initially transfer about 10 microorganisms/g, they will usually feed on the woody part of the hybrid char and then multiply naturally.
It grows to about 20 pieces. As the adsorbent material on which the hybrid briquette char is disposed, use materials that have excellent adsorption properties for oil dispensers, such as cotton cloth, felt, and nonwoven fabric. Then, the hybrid briquette char, in which the facultative anaerobic microorganisms that prefer to digest and decompose fats and oils are transferred to this adsorbent, is processed to a size of about 0.3 to 0.4 g/piece. They are distributed at a rate of about 10 within a 100m square.

They live for a long time while eating. When the wastewater purification material to which microorganisms have been transferred is installed in the wastewater, the pollutants in the wastewater are adsorbed by the micropores of the hybrid char and the adsorbent with excellent oil and fat absorption properties such as cotton cloth. is purified. The adsorbed pollutants are digested and decomposed one after another by the microorganisms, so if wastewater purification materials are installed according to the toxicity of the treated wastewater, it will not become clogged with pollutants and can be used continuously for a long period of time. You can.

また、鉱物性油脂分に関しても動植物性油脂分Next, the present invention will be explained in detail based on examples. 1 in the figure is made from lignite, has a woody part of 1%, and has a porosity of approximately 800.
The wastewater purification material according to the invention of item 1, in which about 10 rhizopods, which are aerobic microorganisms, are transferred to the hybrid char of ♂/g, which has a large number of water passage holes in the middle stage of the septic tank IO. The shelves 11 are made of punched metal with holes cut into 5 cm squares and laid out to a height of 40 cm. Similarly, a septic tank 20 having a wastewater purification material 2 to which about 10 flagellates, which are aerobic microorganisms, have been transferred, and a wastewater purification material 3, to which about 10 ciliates, which are aerobic microorganisms, have been transferred, and 30 are installed in a row. Since the microorganisms in each purification layer are aerobic microorganisms, air is supplied from the air hole 40 at the bottom of the septic tank by a separately prepared blower 4 for aeration. Wastewater introduced from the inlet 12 provided at the upper part of the side wall of the septic tank 10 once falls to the bottom of the septic tank 10, and then passes through the wastewater purification material 1 laid out on a shelf 11 made of punched metal.
It is discharged from the upper discharge port 13 and sent to the next septic tank 20. When passing through the wastewater purification material 1 from bottom to top, pollutants in the wastewater are adsorbed to the micropores of the hybrid char of the wastewater purification material 1 and removed. The wastewater is further purified by the wastewater purification materials 2 and 3 in the subsequent septic tanks 20 and 30, so the last septic tank 3
When the water is discharged from 0, it is purified as shown in Table 1. As is clear from the table, immediately after the purification color is obtained without replenishing the wastewater purification material according to the Eastern Heavy Sewerage Law,
Even after one year of operation, there is almost no change in the composition of the acclimatized wastewater discharged from the final septic tank 30, and all of them significantly exceed the regulatory values. This is because the pollutants adsorbed to each wastewater purification material are digested and decomposed one after another by the transferred microorganisms, so that no clogging occurs. IA in the figure is a wastewater purification material according to the invention described in item 2, and is provided in three stages in a septic tank 10a, held in a stainless steel case lla. The wastewater purification material IA is a cotton cloth 1a with a size of 7 x 20 x 30 cm that has excellent oil and fat adsorption properties, and a hybrid char powder 1' to which about 10 facultative anaerobic microorganisms/g have been transferred. Approximately 0.
It has a structure in which about 40 pieces are processed and distributed in a size of 3 to 0.4 g/piece. Therefore, the wastewater flows into the septic tank 1.
When the wastewater is introduced from the inlet 12a provided on the bottom side of the wastewater and discharged from the upper discharge port 13a, the oil and fat in the wastewater is adsorbed by the cotton fabric 1a of the wastewater purification material IA provided in the center. Since it is removed, the wastewater discharged from the v-trough 13a is purified. Table 2 compares the oil and fat content of raw wastewater and purified wastewater. As is clear from the table, most of the oil and fat content is removed by the wastewater purification material IA of the present invention. Even though the wastewater purification material IA has a high oil and fat content, its purification function does not deteriorate at all even after long-term use. this is,
The fats and oils adsorbed on the cotton cloth 1a can be digested and decomposed and removed in the same way as before. Table 2 (ppm) This is because the cotton fabric 1a does not become clogged because it is successively digested and decomposed by anaerobic microorganisms that are compatible with the Eastern Heavy Sewerage Law. The aerobic microorganisms to be transferred to the hybrid char are selected in each case based on the pollutants suspended or dissolved in the wastewater, but it is difficult to completely purify wastewater with one type of microorganism. Therefore, as shown in the example, three types of microorganisms, rhizopods, flagellates, and ciliates, are generally used depending on the degree of contamination.
It is desirable to install it after llff in order to improve the purification efficiency. The size of the wastewater purification material to be installed may be appropriately determined depending on the amount and concentration of wastewater to be treated. In addition, regarding mineral oils and fats, animal and vegetable oils and fats

The microorganisms that have transferred the adsorbed pollutants to the wastewater purification material digest and decompose them one after another and release them into the atmosphere as harmless gases such as nitrogen and carbon dioxide, which causes the wastewater purification material to become clogged and over time. In both cases, theta conversion function does not deteriorate. Therefore, it has become possible to use it continuously for a long period of time. In particular, by using a combination of wastewater purification materials to which facultative anaerobic microorganisms and aerobic microorganisms have been transferred, it has become possible to purify all types of wastewater containing oil and fat. Furthermore, since the pollutants are released into the atmosphere as harmless gases as described above, the amount to be treated as sludge is extremely small, resulting in lower treatment costs. Furthermore, since it contains wood that provides nutrients for microorganisms, even if the equipment is not used for a long period of time, such as during the year-end and New Year holidays, microorganisms can feed on and live in the wood, providing nutrients for microorganisms. There's no need at all. In addition, since it has a woody part, it has a higher temperature than activated carbon even when placed in wastewater, and even in winter, except in particularly cold regions, it maintains a temperature sufficient for microorganisms to be active, so it requires special insulation. There is also the advantage that there is no Therefore, the wastewater purification material of the present invention has a remarkable effect on purifying not only household wastewater and livestock wastewater, but also wastewater from all kinds of factories such as food processing factories, sake brewing factories, plating factories, oil refineries, vehicle maintenance factories, gas stations, and processing factories. There is.
