Description

  The present invention relates to a sewage treatment facility, and more particularly, to a sewage treatment facility that treats precipitated sludge accumulated in a water stop portion of a settling tank of a sewage treatment apparatus.

  Sewage discharged from restaurants, food processing factories, etc. contains a large amount of organic matter, but in order to treat such wastewater, it is separated into wastewater and sediment by a wastewater treatment device. The dehydrated cake is made and reused or abandoned, and the treated water is discharged into sewers, especially rivers. In modern wastewater treatment methods, organic substances in wastewater are decomposed by microorganisms such as bacteria to promote disappearance, and biochemical oxygen demand (BOD) and suspended solids (SS) are below a certain value. An activated sludge type that is discharged as reduced treated water is known.

  However, in activated sludge type sewage treatment equipment, sludge often settles at the water-stopping site in its separation tank or settling tank, and even if this is collected separately, sludge containing such organic matter is not reused. In many cases, a sludge dehydrated cake was made. Sludge is composed of many microbial cell bodies, and the cell bodies contain about 70% of water, so it is easy to rot even if dehydrated, and eventually incinerated or dumped without being reused. It had been.

  Sediment sludge generated in the sedimentation tank of the sewage treatment apparatus contains a large amount of moving substances, plant tissue cells, and the like from the source, and contains microorganisms propagated along with these. Examples include cell bodies such as bacteria such as zoo glare, ciliates such as Paramecium, algae such as uremo, blue-spotted moth, and diatom, protozoa such as euglena, and metazoans such as rotifer and nematode. These microorganisms contain highly nutritious cytoplasms and nucleic acids containing proteins, sugars, lipids, and amino acids rich in water, so that the precipitates are easily spoiled.

  Sediment sludge generated in the sedimentation tank of activated sludge-type sewage treatment equipment is decayed in a short time, generating toxic gases such as hydrogen sulfide due to C. perfringens, etc. It is being transformed into a new environment and will take away its activity.

  The present invention is a sewage treatment apparatus, in particular, the activated sludge sewage, which is prepared by processing and decomposing the precipitated sludge generated in the settling tank of the activated sludge sewage treatment apparatus to reduce the volume of the treated water to a highly useful sludge. The present invention provides a sludge treatment facility for activating activated sludge in a treatment apparatus.

  The sewage treatment facility of the present invention pulverizes the cells of microorganisms occupying most of the precipitated sludge generated in the sedimentation tank of the sewage treatment apparatus, and then fermented with fermenting bacteria, and contained a large number of fermenting bacteria. This is to make treated water and fermented sludge whose volume is reduced to increase the utility value.

  For this purpose, the sedimentation sludge treatment facility of the present invention has a collecting means for collecting the sedimentation sludge from the water stop part of the precipitation tank in order to treat the sedimentation sludge accumulated in the water stop part or blind spot part in the precipitation tank, Separates the collected sludge into ultrafine particles into ultrafine sludge, a fermenter that mixes fermented bacteria with the ultrafine sludge and ferments the ultrafine sludge in the tank, and fermented ultrafine sludge And a separation tank that separates the treated water and the fermentation sludge in the tank.

  The sedimentation sludge treatment facility of the present invention collects sedimentation sludge that accumulates in water-stopping sites such as the four corners where the stagnation of the flow in the sedimentation tank of the sewage treatment apparatus is likely to occur together with water in the ultrafine particle device, It is differentiated into extremely fine particles by the atomization device, and the tissues and cells of animals and plants and microorganisms that form sludge are refined and diffused, and the surface area is increased. The fermenting fungus tank decomposes the decomposed organic matter in a large amount in a short time with the fermenting fungus mixed in the tank, converts the sludge organic matter into the remaining inorganic content, and then the treated water rich in fermenting fungi in the separation tank It is separated into inorganic sludge that has been greatly reduced in volume during the growth of fermenting bacteria.

  Furthermore, in the present invention, the settled sludge is removed from the settling tank of the sewage treatment apparatus regularly or regularly through the treatment facility, and the activated sludge in the sewage treatment apparatus, particularly the activated sludge type sewage treatment apparatus, is removed. The activity can be maintained, and the degradation rate and efficiency of sludge can be increased.

  Sewage treatment equipment treats industrial or domestic wastewater or wastewater containing a large amount of organic matter discharged from restaurant kitchens, food processing plants, apartment houses, etc., and decomposes organic matter in wastewater. Thus, the treated water can be discharged. In particular, an activated sludge sewage treatment device is included, and the wastewater standard is satisfied so that it can be discharged into a river or the like. Such a sewage treatment device guides sewage to a decomposition tank or an aeration tank, decomposes organic matter such as animals and plants and bacterial tissues and cells in the sewage by the action of bacteria and other microorganisms, and biochemical It is discharged as treated water in which the oxygen demand and the amount of suspended solids are reduced below a certain standard.

  The sewage treatment apparatus includes a settling tank for separating organic substances from the treated water, and sludge is precipitated in the water stop area of the settling tank, and the present invention treats such precipitated sludge. It is. Here, the term “sedimentation tank” includes a processing tank that is included in a sewage treatment apparatus and that tends to generate a liquid flow retention site in the tank to easily cause sedimentation of organic sludge. An aeration tank, a decomposition tank, and a sedimentation tank Is included.

  The treatment facility of the present invention includes a sludge collecting means for transferring the precipitated sludge to the ultrafine particle forming apparatus. An example of the collecting means is connected to the suction apparatus and the suction apparatus, and the suction port is in the tank. In particular, there are some which consist of flexible or fixed piping which can be positioned at the water stop. A flexible hose or a fixed pipe can be used for such piping, and the suction device has a pump connected to these piping. The pump can be further connected to an ultrafine particle generator.

  Collecting means, unlike the case by human power, because the suction port of the flexible hose or pipe is connected to the water stop part of the sedimentation tank of the sewage treatment device, collect the precipitated sludge as appropriate without stopping the operation of the equipment, It can be transferred to an ultrafine particle device.

  The collected precipitated sludge disperses organic matter such as animal and plant cell tissues and microbial cells in a large amount of water, but the ultrafine particle device atomizes these organic matter into ultrafine particles having a size smaller than the cell size in the precipitated sludge.

  For this purpose, the ultrafine particle device uses ultra high-speed water flow to these cells to further destroy the tissues and cells of animals and plants and microorganisms by the action of shearing, destruction, decomposition, etc. Things are available.

  For such an ultrafine particle device, one or more of the impact force of high-speed water flow, shear force due to difference in water flow velocity, or ultrasonic decomposition caused by bubble rupture or cavitation should be used. Can do.

  One aspect of the ultrafine particle forming apparatus includes a container composed of an inner cylinder and an outer cylinder arranged concentrically and an annular channel between them, and a water jet nozzle that forms a high-speed water flow along the annular channel. , A slot that is formed on the inner cylinder wall and discharges the precipitated sludge water from the inside of the inner cylinder into the high-speed water flow in a substantially perpendicular direction, a sludge supply port that communicates with the inside of the inner cylinder, and sludge refinement that communicates with the annular channel It consists of a particle outlet.

  Inside the annular channel, a high-speed water stream is circulated by the water jetted from the water jet nozzle. From the slot formed in the inner cylinder wall, the slurry is discharged into the annular channel as a slurry containing organic matter of precipitated sludge to be crushed. Therefore, the organic particles in the sludge can be decomposed to the size of a single cell or finer by being sheared, broken, and decomposed by a high-speed water flow.

  The fermenting fungus tank is a fertilizer that mixes fermenting bacteria in the tank with the sludge ultrafine particles from the ultrafine particle generator, and has a receiving tank that accepts the liquid containing the sludge ultrafine particles. It is designed to stay for a certain period of time, and preferably it is suitably equipped with a stirrer that stirs and mixes the liquid and a suitable temperature adjustment device that maintains a suitable temperature for fermentation to promote uniform fermentation decomposition.

  Fermentative bacteria used for fermenting refined sludge in fermenting fungi tanks can be widely used commercially available bacteria and fungi that microbiologically decompose fine particles such as animal and plant tissues and microbial cells . Such fungi include, for example, lactobacilli as well as yeasts and bifidos.

  As another form of mixing the fermenting bacteria, it is also possible to use bacteria obtained by collecting a plant or soil to which bacteria are attached from the natural world and culturing them from this sample using a culture apparatus. As fungi that can be used for such fermentation, lactic acid bacteria, for example, Lactobacillus can also be used, such as yeasts and bifido species. As fermentative bacteria, for example, lactic acid bacteria may be collected from plants or soil around the sewage treatment apparatus.

  For the sample containing the collected fermentative bacteria, it is necessary to cultivate some useful fermentative strains from a large number of miscellaneous bacteria included in the data. Expansion culture methods can be used.

  Lactic acid bacteria and other fermentative bacteria collected together with plants or soil can be separately cultured using a separate culture apparatus. The culture apparatus is preferably provided with a micronization part and a culture tank, and the micronization part can be suitably used by utilizing the impact force of a high-speed water flow, the shearing force due to a large water flow velocity difference, or bubble collapse, that is, cavitation. Atomize organic material for culture. The culture tank cultivates the fermenting bacteria using the atomized organic material as a culture substrate. In this culture device, the cell membrane of organic material is also pulverized in the atomization part, the intracellular substances are dispersed in the culture solution, and the solid content greatly expands the surface area. can do.

  However, the atomization unit supplies the culture tank with a part of the sludge fine particles from the ultra fine particle device so that the ultra fine particle device that atomizes the precipitated sludge also serves as the culture medium for fermentation bacteria. It is preferable to use it.

  The separation tank separates the sludge ultrafine particles fermented in the fermentation bacteria tank into treated water and fermentation sludge, and performs solid-liquid separation in an appropriate precipitation tank or filtration tank.

  The treatment facility of the present invention preferably further includes a step of treating the fermented sludge separated in the separation tank using a rapid fermentation decomposition sludge treatment machine. In the rapid fermentation and decomposition sludge treatment machine, the remaining organic matter is efficiently decomposed into water, carbon dioxide and inorganic components by the fermenting bacteria after receiving rotational agitation.

  The treatment facility may further include a pipe that circulates by supplying the treated water separated in the separation tank to the settling tank of the sewage treatment apparatus. Since the treated water contains fermenting bacteria grown in large quantities by the organic matter of the precipitated sludge that has been made into ultrafine particles, it can be used for the activated sludge treatment of the sewage in the settling tank of the sewage treatment apparatus. As described above, the sedimentation tank includes an aeration tank, a decomposition tank, or a sedimentation tank of the sewage treatment apparatus.

  From the above description, the inorganic sludge obtained by the treatment facility of the present invention is mostly inorganic and can be used for land improvement without being spoiled.

  On the other hand, the treated water obtained by the treatment facility of the present invention, as described above, can be supplied to the activated sludge type sewage treatment apparatus, in particular, returned to the sedimentation tank and mixed to supply the fermentation bacteria. It can be activated to reduce biochemical oxygen demand (BOD) and suspended solids (SS) below a certain value in a short time. The treated water obtained by the treatment facility can be discharged to a river or the like as purified water through a sewage treatment apparatus.

  Moreover, said treated water obtained by the processing equipment can also be sprayed and mixed with, for example, leftover food during temporary storage or waste food, thereby suppressing the generation of malodor during storage. Treated water may be mixed with livestock manure in the field of livestock production, and can promote composting that is rich in nutrients and has less offensive odor. The treated water can also be used for purification of lakes and rivers and land improvement.

  In the sewage treatment facility of the present invention, for example, certain photosynthetic fungi having a symbiotic relationship with lactic acid bacteria can be mixed with the fermenting bacteria added to the fermenting bacteria tank.

It is expected that the photosynthetic fungi receive sunlight in the fermenting fungus tank and perform photosynthesis, and the fermenting fungi can increase the growth ability and supply the necessary symbiotic substances to accelerate the culture. Some species of photosynthetic fungi ingest malodorous substances generated by spoilage as nutrient sources. In the present invention, such photosynthetic fungi include, for example, red non-sulfur bacteria group (Rhodospirillaceac family) and the like (for example, commercially available as “Zilla fermenting bacteria group” of Geeland)
Is available.

  Photosynthetic fungi are rich in amino acids, minerals, vitamins, and other excellent nutrients, and the cells themselves are useful as organic fertilizers, but certain photosynthetic bacteria generate sulfate-reducing bacteria when they encounter septic sludge. It is also known to actively take in hydrogen sulfide as a nutrient source. It is known that certain types of photosynthetic bacteria prefer to take toxic amines putrescine and cataverine and carcinogenic teratogenic dimethylnitrosamine as a substrate and decompose and remove them.

  In addition, when photosynthetic fungi are reduced to green farmland, they can decompose and remove harmful substances that the roots of crops dislike, protect root respiration and nutrient metabolism systems, and also perform nitrogen fixation to increase the yield of crops. .
