Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for treating organic sewage. More specifically, for example, when extracting black tea in a food factory, too much squeezing causes bad taste such as bitterness or turbidity. You may stop squeezing hard with. When this squeezed waste is piled up and put on the floor or the bottom of the box, if it is put into the sewer as sewage, the sewage treatment facility will be overloaded and the construction cost will increase.

2. Description of the Related Art Conventional methods for treating sewage and waste water include, for example, a chemical sludge treatment method disclosed in JP-A-8-170874 and a waste water purification treatment disclosed in JP-A-2-268882. There are ways. The chemical sludge treatment method is a method of chemically reacting a treated substance with quick lime, and a first treatment step of collecting and transporting organic and inorganic sludge generated from sewage, drainage, rivers, etc., and the treated sludge with quick lime. Is a chemical sludge treatment method comprising a second treatment step of chemically reacting with the above, and a third treatment step of thermally forming the chemically treated treatment sludge. According to this treatment method, since sludge of human waste, such as humans, animals and livestock, and excrement can be purified, sludge can be regenerated and reused as a soil improver or a soil improver, It can purify sewage and factory wastewater sludge discharged from homes, factories, etc., that wastewater sludge can be regenerated and reused as a soil conditioner or soil conditioner, polluted rivers and Since general sludge such as lake water can be purified, sludge can be recycled and reused as a soil improver or soil improver, and sludge discharged from road construction or civil engineering work can be purified. As a result, sludge can be regenerated and reused as a soil improver or a soil improver. On the other hand, the purification method of wastewater relates to a method for purifying wastewater of factory wastewater containing heavy metals such as copper, cadmium, mercury, lead and zinc and sewage including detergents, edible oil, human waste, etc. The natural shell fossils containing various components of nectons, plankton, algae, and seaweeds such as calcareous and silicic acid are crushed into small grains or rough sandy coarse ores and naturally dried, and at 120 ° C to 450 ° C. It is dried with hot air and refined into powder and granules.
The main component is a treated substance purified to a particle size of about 50.00 μm from m, and the treated substance includes factory wastewater containing heavy metals such as copper, cadmium, mercury, lead and zinc, detergent, edible oil, and human waste. It is a method for purifying wastewater characterized by being mixed with wastewater such as sewage to effectively adsorb and collect wastewater substances, and further allowing reuse of wastewater by ion exchange and neutralization. . According to this treatment method, wastewater such as factory wastewater and sewage can be purified without using any chemicals, and in addition, secondary pollution can be prevented and the treated water can be reused as industrial water. It can be said that it is a wastewater purification treatment method that can be used and is far superior to conventional methods in all respects such as treatment ability, economic efficiency, and corporate property because the treatment substance is a natural product. Natural shell fossils containing various components of nectons, plankton, algae, seaweeds such as calcareous and silicic acid are crushed into small or coarse sandy coarse ores and dried naturally with hot air drying at 120 to 450 ° C. It is refined into powder and granular form, and further treated with air to be refined to a particle size of about 0.10 μm to 50.00 μm, so it is the optimum treatment as a shell fossil for wastewater purification treatment. The substance is to be obtained.

Furthermore, recently, a treatment method has been developed in which manure of livestock is put in a closed container and anaerobic fermentation is performed to generate methane gas, which is used as fuel for cooking or as fuel for a generator to obtain electric power. . The present invention has developed a method for treating organic soil by this anaerobic fermentation.

[0004]

According to such a conventional method, the residual lees after fermentation in the closed container are separated from water, and then the solid content is reduced to the fields as compost or incinerated to bury the ash content. I'm afraid. And since the water flows into the sewer, it put a lot of load on the sewage treatment facility. Further, when the solid content is compost, if the water content is high, the fermentation for compost does not occur, so there is a problem that the water must be separated. Further, the squeezed lees of tea leaves produced during the production of black tea also had the same problem. On the other hand, this water is rich in organic matter, and the sewage treatment facility cannot discharge the water to rivers etc. unless the organic matter is removed to below the specified concentration. I was burdened. In this way, the organic matter must be removed to below the specified concentration, and there is a locational constraint that there must be a river that can discharge the end of the stream. In consideration of such problems, wastewater is treated without burdening the existing sewage treatment facility with activated sludge, and moreover, moisture is evaporated into the air and the end of the facility is never discharged to rivers, etc. However, there is a problem to be solved by the present invention in an attempt to provide an organic wastewater treatment method that does not require end-of-stream treatment without the restriction that it must be close to a river.

[0005]
