Description

  Organic waste multi-digestion treatment of independent facilities {DISPOSAL METHOD OF AN ORGANISM WASTE MULITIPROSESS DIGESTS}

  The present invention is a method of multi-digestion treatment of organic waste of independent facilities, more specifically, foreign technology such as livestock powder is used to ferment by storing organic waste in a circular general tank, which is difficult to power If a plant made at a huge cost cannot use its function, and fermentation in one space leads to a breakdown in digestibility, it is necessary to remove thousands of tons of organic material from the digester. It happens

In addition, it is an independent facility that can be used as fuel or fertilizer as well as treating environmental excrement, animal waste, and food waste generated when living in islands, mountains, and remote areas where sewage treatment facilities are not provided. The present invention relates to a method for treating multiple wastes of organic waste.

In 2012, the London Convention on the Prohibition of Organic Maritime Affairs and the High Oil Price era solved the import substitution effect of high oil prices by producing eco-friendly treatment and alternative renewable energy.In general, in dense residential areas, considering residential environment and public hygiene, There are already facilities for domestic waste that are essential to daily living, but sanitation-related facilities have been resolved in farming and fishing villages away from dense residential areas.

In other words, since the sewage and sewage facilities were built independently to treat domestic wastewater, the cost of the facility was very heavy, while the treatment efficiency of pollutants was reduced, and there was a drawback of causing secondary pollution by releasing untreated sewage into nature.

In particular, in the area adjacent to the soldering or intake source or in the area where the water supply and sewage facilities are impossible, most of them rely on conventional methods to treat organic waste, which is unsanitary and inconvenient for treatment, and contaminates water quality in severe cases.

It is known that the organic waste treatment method produces a methane gas by fermenting and stabilizing sludge as microorganisms are digested by the activity of anaerobic bacteria in a state in which organic substances remain in a storage tank.

However, in the conventional fermentation treatment method, when there is no power source such as electricity, the organic material stored in the tank solidifies and precipitates in the form of sludge over time, so that the agitation is properly performed when the organic material having high moisture content is introduced into the storage tank. It was not made, thereby changing the concentration there was a problem that causes disorders in the digestive function of microorganisms.

In addition, if the extinguishing function of the stored organic material is lost due to the change in concentration as described above, there is also a drawback that the storage function is also lost, resulting in a saturation state and a new treatment facility must be prepared.

  The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to provide an organic waste multiple digestion treatment method of an independent facility that can activate the digestion activity of microorganisms when the organic waste is stored and treated in a multiple digestion system. It is.

Another object of the present invention is an organic waste treatment method of an independent facility that can maintain a uniform concentration at all times, even when a power source is provided or not, stably prevents sludge formation due to solidification and precipitation of organic substances stored in the system. In providing.

  The present invention for achieving the above object, the organic waste is stored in the tank in which the organic waste from the inlet is configured to produce biogas, while the intermittent stirring by the operation of the motor inside the storage tank to solidify or settle phenomenon Stirring cabinet to prevent

And a cogeneration system for maintaining a suitable temperature suitable for microbial activity, a pH adjusting device, a desulfurization device for removing sulfuric acid gas, a device for removing water and siloxane in biogas, etc. It efficiently handles organic materials of polymers and features a fire extinguishing system that does not leave 0% of waste residues and 100% of organic wastes such as renewable energy, electricity, hot water, biogas, and compost.

In addition, it is digested and processed in seven times. It is digested in stages with four gastrointestinals of some herbivores, and it applies the digestive system that absorbs the energy source of food as much as possible and discards it outward. It is characterized by discharging each individual step by step and dissolving it into final alkaline liquid fertilizer until it is composted and discharged.

  Such organic waste multi-digestion treatment method of the independent facility of the present invention is more environmentally friendly and easily treated using the organic waste and animal husbandry ingredients that are essential to the process of people's lives, resulting in water and soil pollution, etc. Preventing the causes of environmental pollution, creating and recovering energy for high oil prices, the processed remnants are transferred to the liquid fertilizer or solid composting process, which is the perfect endless recycled energy source that is supplied to the nutrients of people's food.

In addition, when inoculating the first communicable strains, the existing method directly costs the cost of tens of millions of dollars by directly administering the seed, and once the seed is inoculated, it cannot guarantee the stabilization.

During the first inoculation of the present invention, the minerals such as sawdust and rice bran are mixed with the organic material to be treated with the organic material to be treated, and then fermented for a certain period of time. Therefore, active growth of communicable strains and methane gas, that is, biogas, also have more productivity than conventional methods.

  Hereinafter, the organic waste multiple treatment method of the independent facility of the present invention will be described with reference to the accompanying drawings.

1 is an example of a system for the multiple treatment of organic waste of the embodiment of the present invention, Figure 2 is a flow chart of the step-by-step independent digestion and final discharge of the organic waste of the present invention, Figure 3 is a flow for the treatment of the entire organic waste It is a chart.

The organic waste is crushed through the inlet 50 through the crusher 70 of FIG. 2 for the optimal decomposition of organic matter by primary agitation and anaerobic bacteria, and solids other than organic matter are collected inside of the anaerobic bacteria. Before passing through the opening (30H) step by step by the action is discharged through the non-organic material step device 10 and the discharge screw 11 for discharging the non-organic material to the outside.

Emissions discharged to the outside are once again classified into organic and non-organic materials, and the organic materials that can be recycled are re-injected through the organic transport pipe 54 to the inlet 50 of the digestive system, and are not digested by the extinguishing system. Non-organic materials are separated and disposed of.

Five partitions 31, 32, 33, 34, and 35 are formed at predetermined intervals to partition the internal space according to the extinguishing characteristics for complete extinguishing of fire extinguishing system and energy resources. On the side, the liquid matter is discharged through the liquid composting discharge port 53 in the alkaline fermentation and liquid fertilizer storage tank 46 and the opening and closing device 30H, 31H, 35H, in which organic substances move and pass through each fire extinguishing chamber. When discharged to the composting device, openings 30H, 31H, and 35H are sequentially opened, and organic materials pass through each fire chamber, which flows naturally without using power on the principle of the organic material natural flow slope 57. It is inclined downward so as to be inclined downward, and each fire compartment partition wall without the opening / closing device (30H, 31H, 35H) is spaced at a predetermined interval as shown in FIG. Like 60) (61) (62) (63) (64) The continuous circulation flow maximizes the length of the flow to promote complete digestion in each digestion chamber and to ensure vigorous activity of the anaerobic bacteria, and sequentially to acid lowering enzymes (42) (43) (44). (45) The acidic pH is dropped into the alkaline fermentation to the alkaline fermentation and liquid fermentation tank (46).

In order to make the conditions of active activity of the first anaerobic bacteria and anaerobic bacteria, the acidic fermentation tank (41) at the time of inoculation has a fermentable anaerobic bacteria which ferments the organic material of the polymer constituting the main component of the organic material into the low molecular weight organic material by the digestion activity of the microorganism. Inorganic materials such as sawdust, rice bran, crushed dry grass, etc. and poultry discharged from poultry farms can be mixed 8 to 2 properly to promote biogas production. 30% of promoted minerals are added to increase anaerobic bacteria for a certain period of time, and ensure the activity of abundance.

This also serves as an environmentally friendly promoter in the natural environment and further saves tens of millions of won of the initial method of inoculation.

One side of the system is operated intermittently in the stirrer (20 (21) 22) to prevent the phenomenon of solidification or precipitation by the passage of the storage of the organic material time.

In the primary acid fermentation tank (41) and the secondary acid fermentation tank (42), the tertiary acid fermentation lowering tank (43), and the fourth acid fermentation lowering tank (44) while further decomposing the fatty acid of the introduced organic material to make the concentration bite. Methane gas, or biogas, generated during the digestion process by each anaerobic bacteria is generated, and the biogas is less dense than air and has a force of rising upward. The biogas generated from the biogas spout hole 51H and the secondary acid fermentation tank 45 of the primary acid fermentation tank 41 and the secondary acid lowering fermentation tank 45 are taken up on the condensed water flow slope 58 in the air to be secondary acid. It passes through the biogas capture hole 51H of the fermentation tank 42, passes through the biogas discharge port 51, and is conveyed to the biogas processing plant part, such as a biogas collection tank.

At this time, in order to activate the activity of microorganisms in the winter when the temperature is low, each fermentation tank divides the heat produced by the cogeneration system using biogas, and uses the heating pipe 59 of FIG. Maintain an optimal digestion system by maintaining a temperature of 38 ~ 38 degrees and installing an acidity regulator.

On the other hand, the alkaline fermentation tank 46 located on the lower side of the slope of the organic material natural flow slope 57 accommodates the so-called liquid fertilizer changed into an alkaline liquid form through the fermentation process, the liquid fertilizer outlet and eyepiece installed on the upper side Through the sphere (53) to react the sludge of the stored liquid fertilizer to maintain the optimum conditions for the digestion activity of the microorganisms.

The liquid rain outlet and the eyepiece confirmation port 53 is made of a transparent tempered glass cover and is normally locked so as not to emit odors.
