Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention eliminates the need for collecting urine excreted in toilets and discharging it into sewage, and
The present invention relates to a deodorizing treatment method and a treatment device.

[0002]

2. Description of the Related Art In areas without sewage facilities, feces and urine excreted in toilets are collected in toilet tubs and pumped. However, the urine collected in the toilet tank emits an odor from the toilet tank. In addition, if the toilet is flushed without sewage, a large amount of flush water and feces and urine are collected, a large-capacity toilet tank is required, and the amount of water to be pumped is increased. Further, even if individual simple purification facilities are laid, the treatment cannot be completely performed, and therefore, the treatment liquid is not allowed to flow into the sewage. Further, even if the treatment liquid can be discharged by the simple purification equipment, it is necessary to periodically remove sludge-waste deposited in the tank and clean it. As described above, the conventional equipment is problematic in terms of environmental health and labor.

[0003] Accordingly, the applicant has filed Japanese Utility Model Application No. 63-46667.
Has filed an application for the invention of an odorless toilet evaporator, and has filed an application in Japanese Patent Application No. 6-24851 concerning the deodorization of urine in two tanks. Furthermore, Japanese Patent Application No. 8-54115 has been filed as a method and apparatus for further improving the effects of eliminating odors, removing pumps, and eliminating the need for sewage. This water is blown into the feces and urine and the washing water from the toilet in the first pretreatment tank with heated air, and is preliminarily decomposed by the aerobic bacteria in the hydrofiltration. Filtration nets are used to filter coarse organic contaminants, and the filtered filth is heated by a heater in the subsequent main treatment tank while air is blown in to replenish oxygen to completely decompose the filth by the action of aerobic bacteria. It is deodorized into a gas consisting of gas, water vapor, hydrogen gas and nitrogen gas and released into the atmosphere. However, if the inlet of the exhaust stack that releases the decomposition gas of the filth by the aerobic bacteria into the atmosphere from the first pretreatment tank or the main treatment tank is located at the middle position below the highest position in the treatment tank, As a result, carbon dioxide gas or nitrogen gas is stored in the tank above the suction port, and is not sufficiently discharged out of the tank, resulting in a shortage of oxygen in the tank. Also, if there is no sufficiently large air retention area above the surface of the filth in the first pretreatment tank or the filtered filth in the main treatment tank, sufficient oxygen can be supplied to the filth or filtered filth. And the amount of oxygen in the tank becomes insufficient. For this reason, there is a possibility that the aerobic bacteria may die due to lack of oxygen, and the waste may not be sufficiently decomposed. Further, it is desired to improve the filtration efficiency of the coarse organic impurities in the second pretreatment tank.

[0004]

Deodorizing treatment device.

According to the fourth aspect of the present invention, there is provided a float for detecting the level of the surface of the filtered contaminated liquid between the position of the heater disposed at the bottom of the layer of the main treatment tank and the air outlet of the air outlet pipe. A float switch that responds to the rise of the float is installed at the tip of the detection rod that protrudes from the upper end of the float into the main processing tank, and a warning lamp that is activated by the float switch is installed outside the tank, and further installed outside the tank 4. An apparatus for deodorizing stool and urine which does not require pumping and sewage according to the means of claim 3, wherein a temperature sensor wired to the thermostat is provided immediately above the heater.

The operation of the present invention will be described below. In the method for deodorizing feces and urine of the present invention, air is ejected from the air jet nozzle into the hydrofilament composed of feces urine and washing water flowing from the toilet into the pretreatment tank, and the hydrofilament is vigorously agitated. Supply oxygen to At the same time, air is blown onto the surface of the waste from the air outlet facing the surface of the waste in the pretreatment tank. Aerobic bacteria are inhabited in the filth along with defecation or naturally supplied from the atmosphere.
This aerobic bacterium proliferates very actively due to the oxygen contained in the air supplied in the hydrofouling and actively decomposes the fouling into sewage and then converts it to carbon dioxide and water vapor. In addition, ammonia, which emits a bad smell, is decomposed into hydrogen and nitrogen by the stirring action of air and the decomposition action of aerobic bacteria, so that no bad smell due to ammonia is generated.
The pre-treatment tank or the main treatment tank has a sufficient space for air to stay above the waste or waste liquid to be treated, and the exhaust pipe that allows gas generated by decomposition by aerobic bacteria to escape to the outside of the tank is the highest point in the tank. From the bottom of the tank, and furthermore, an air outlet is provided facing the liquid surface of the waste or the waste liquid, and the air is strongly blown to the waste or the waste liquid by the blower. Gases harmful to aerobic bacteria such as hydrogen gas and nitrogen gas are expelled without accumulating in the tank.

The waste pretreated in this way overflows from the side wall of the pretreatment tank while maintaining a constant water level, and is sent to the next two-stage filtration tank. In the two-stage filtration tank, coarse organic contaminants such as fats, starch, and plant fibers which are separated by a partition wall into two chambers of a first filtration chamber and a second filtration chamber and which are not decomposed in the pretreatment tank are removed by the first filtration chamber. The filter soil removed by a coarse filter in the filtration chamber, for example, a 2 mm filter net, and further filtered by the coarse filter net, further contains medium-sized organic impurities contained therein, for example, 1. A two-stage filtration is performed by removing with a 3 mm filter net to make a filtrate. If it is necessary to replace the filtration net with the remaining organic impurities by a two-stage filtration with a new filtration net once a month in February, it is necessary to replace it once in March. The processing time required to process 10 liters for a family of five persons at a rate of 2 liters of defecation and urination per person per day is 7 hours, which is 5 hours. When the filtration net containing the exchanged organic contaminants is wrapped around the upper space in the two-stage filtration tank by appropriate means and held until the next exchange of the filtration net, the organic contaminants in the filtration net are dried,
It becomes a suitable organic fertilizer after being deodorized and reduced in weight.

[0011] The filtered waste liquid filtered in the two-stage filtration tank flows into the final main treatment tank. Maintaining the pretreatment tank at a constant water level as described above provides a sufficient pretreatment period to stabilize the aerobic bacterial decomposition activity, and to always maintain a constant aerobic bacterial survival, and to maintain the final stage. It is indispensable to optimize the decomposition activity of aerobic bacteria in the main treatment tank. Further, the survival of the aerobic bacteria contained in the two-stage filtration tank also promotes the decomposition.

In the main treatment tank, the waste liquid is heated to about 25 ° C. to 30 ° C., optimally 28 ° C., which is the active temperature of the aerobic bacteria, by the heat generated from the heater disposed in the waste water. Bacterial decomposition activity is activated. Further, oxygen is supplied to the aerobic bacteria in the waste liquid by blowing air into the waste liquid and vigorously stirring the waste liquid. Since aerobic bacteria require an extremely large amount of oxygen to operate, air is also blown out from the surface of the sewage to drive off the heavy carbon dioxide gas or nitrogen gas generated, and the aerobic bacteria on the surface of the sewage are discharged. Oxygen is added to oxygen to further activate the activity of aerobic bacteria and further enhance the decomposition of sewage. As a result, the waste liquid is completely decomposed and converted into water, and carbon dioxide is generated. The exhaust gas is completely deodorized because the sewage has been sufficiently decomposed and ammonia has been decomposed into hydrogen and nitrogen by air stirring and the decomposing action of aerobic bacteria. Then, the liquid stored in the main treatment tank is liquefied without generating sludge, and is further vaporized and reduced. Therefore, in the treatment apparatus according to the method of the present invention, no pumping is required, and there is no need to discharge it as sewage.

By the way, a thermostat temperature sensor for controlling the heater is disposed in the vicinity of, for example, 7 mm above the heater installed at the bottom of the main processing tank, and the temperature of the waste liquid is set to 25 which is the optimum activity temperature of the aerobic bacteria. ℃ to 30
The temperature is kept at about 28 ° C., particularly the optimum temperature of 28 ° C. by the heater. As the amount of liquid stored in the main processing tank is reduced due to the decomposition of aerobic bacteria, the liquid storage surface is lowered from the position where the temperature sensor and the heater are installed, and the temperature sensor and the heater are finally exposed. In such a state, since the heater is not obstructed by the liquid storage, the temperature of the heater directly reaches the temperature sensor, so that it is immediately detected and found that the liquid storage has decreased. Thus, when a temperature exceeding the heater set temperature of 25 ° C. to 30 ° C., which is the optimum activity temperature of the aerobic bacteria, is detected, the thermostat is operated to turn off the heater. Therefore, even if the waste liquid is decomposed by the activity of the aerobic bacteria and the water evaporates, the waste liquid in the main treatment tank does not drop below the temperature sensor. Therefore, the aerobic bacteria are not killed because the waste liquid is not completely lost. It does not overheat, is safe and does not consume extra power. With the above operation, the temperature sensor of the thermostat for controlling the heater functions as a lower level sensor of the liquid storage.

The set temperature of the main processing tank can be set to an arbitrary temperature according to the amount of wastes to be treated by a thermostat for controlling the heater. For example, if the toilet is used by 5 to 8 family members, the temperature is set to 30 ° C. If the room is used by 4 or less people, the temperature is set to 24 ° C. Can be processed.

On the other hand, when various kinds of instruments in the main processing tank are out of order and the waste liquid rises to about 25 cm or more from the bottom of the tank, the activity of the aerobic bacteria becomes insufficient. Therefore,
A float using an empty bottle of a PET bottle is floated on the surface of the waste liquid in the main treatment tank, and a float switch that responds to the rise of the float is provided at the tip of a detection rod projecting from the upper end of the float to the upper tank. . Then, the sewage rises above the sewage surface level slightly below the air blowing pipe that blows air to the sewage surface in the main treatment tank, for example, about 25 cm from the tank bottom, and the float rises. It is set so that the float switch is activated when it is done. In this way, the float acts as an upper level sensor for the waste liquid. Then, a warning lamp that is turned on by the operation of the float switch is installed in the toilet outside the tank. Note that the inner volume of the main processing tank is sufficiently large, and there is a sufficient capacity for receiving the waste liquid for at least 10 days after the alarm lamp is turned on.

An air jet nozzle for blowing air into the waste liquid in the main processing tank and stirring vigorously is arranged horizontally at the bottom of the tank, and the nozzle has a large number of plural air blowing holes in the horizontal direction. The ejected air is uniformly blown into the waste liquid over a wide area, and efficiently agitates the waste liquid.

As mentioned above, the main treatment tank has an extremely small amount of stored waste liquid. Therefore, the deodorizing treatment tank is buried deep in the soil where the temperature does not change much according to the season, the temperature change of the processing tank main body is reduced, and the activity temperature of the aerobic bacteria is kept constant.

In the present invention, even if bacteria are mixed in the gas exhausted from the pretreatment tank and the main treatment tank, the bacteria are suffocated and sterilized by the carbon dioxide in the exhaust gas rising in the exhaust pipe. Only clean gas is released from the cylinder and it is safe without contamination.

Further, it is also possible to improve the pretreatment tank without removing the existing one-tank type purification stool which has already been installed, and to easily use the stool urine deodorization treatment tank of the present invention.

As described above, according to the present invention, the sewage pretreated into sewage by the decomposition of aerobic bacteria in the pretreatment tank overflows from the side wall of the pretreatment tank while maintaining a constant water level. After being transferred to the two-stage filtration tank, the organic impurities remaining without being decomposed by the pretreatment in the pretreatment tank are filtered through the first filtration net and the second filtration net installed in the two-stage filtration tank, and then filtered. The wastewater flows into the main treatment tank and is kept at a constant level at a sufficient height in the pretreatment tank, so that a sufficient pretreatment period can be secured and the decomposition activity of aerobic bacteria is stabilized, We always try to survive more than a certain amount.

Further, since a large space area is provided above the stored waste or the stored waste liquid in the pretreatment tank or the main treatment tank, even if a large amount of gas is generated due to the decomposition of aerobic bacteria, A large amount of air can be taken into the tank without being disturbed by these gases, and this space is filled with sufficient oxygen, and the lid of the tank has a funnel-like convex curved surface with the highest part in the center. Since the exhaust pipe is erected at the center of the highest position and exhausted, the gas flow is good, and the gas generated by decomposition is efficiently exhausted. Therefore, the aerobic bacteria do not slow down or die due to lack of oxygen.

Since the organic contaminants are removed in two stages in the two-stage filtration tank next to the pretreatment tank, the treatment efficiency is improved and the number of maintenances is reduced from once every February to once every March. Decrease. In addition, the activity of decomposing aerobic bacteria in the main treatment tank at the final stage is optimized. Therefore, stool waste is sufficiently decomposed by these three-stage treatment to generate carbon dioxide and become sewage, and the sewage is further decomposed to form steam and released from the exhaust stack. For this reason, no waste remains in the main treatment tank and the water level does not increase, so that pumping is not required and sewage is not required because no waste liquid flows out. Further, since the odorous ammonia is decomposed into nitrogen and hydrogen by the stirring action of the air and the bacteria and released from the exhaust pipe, there is no odor. Furthermore, since bacteria are killed by carbon dioxide emitted in a large amount in the exhaust stack, no bacteria are released from the exhaust stack, which is sanitary.
Furthermore, the lower level sensor and the upper level sensor constantly monitor and operate the inside of the processing tank, so that the operation can be performed safely and efficiently. Further, the organic contaminants are dried, reduced in weight and deodorized, and recovered as excellent organic fertilizers. The present invention has excellent functions and effects which are not expected by the conventional treatment method and the toilet tank.
