Description

Culture medium of microorganism for purifying a river}

The present invention relates to a microbial incubator for river purification, and more particularly, to an apparatus capable of efficiently culturing microorganisms while actively responding to a situation that may occur in culturing microorganisms for river purification.

In general, there are several physicochemical and biological methods of treating wastewater. Among them, the physicochemical method is expensive and has disadvantages of reprocessing the product after treatment, whereas the biological method decomposes and stabilizes a large amount of organic components in the form of carbon dioxide or generates methane gas to generate organic matter in the wastewater. By eliminating, the amount of product after treatment is relatively small.

The biological treatment method mainly uses microorganisms to decompose, detoxify and separate contaminants in wastewater, and is mainly used for secondary treatment of urban sewage, factory wastewater containing organic substances, and sludge produced therefrom. It is the most widely used wastewater treatment method in the world due to expenses and various processes.

The microorganisms, which play a key role in the biological treatment, are mainly cultured and grown in an incubator and are mixed cultures composed of microorganisms of different populations of bacteria, fungi, protozoa, and welfare animals, while proliferating using dissolved oxygen dissolved in wastewater. Organic contaminants are used as nutrients to purify wastewater by decomposing and removing organic contaminants.

The incubator in which the microorganisms used for such biological treatment are cultured is a device that creates an environment similar to the natural environment conditions in which arbitrary microorganisms can be best cultured and supplies solutions, organic and inorganic media, and air to be cultured inside. By culturing and growing the microorganisms.

This wastewater purification method is also used for river purification. As a result of EM, which is made by mixing molasses and water with 80 kinds of mixed microbial stock solutions such as photosynthetic bacteria, lactic acid bacteria and yeast, and aging for 35 days at a temperature of about 0.5t daily, the oxygen demand is considerable.

Referring to FIG. 1, the culture tank 200 will be described.

EM is made by mixing molasses and water in 80 kinds of mixed microbial stock solutions such as photosynthetic bacteria, lactic acid bacteria and yeast, and ripening at 35 degrees for one week. The aging step is performed in the culture tank 200.

The culture tank 200 is provided with a temperature sensor, a water level sensor, a temperature control device and the like as in the conventional case to create an environment required for culture conditions.

Referring to FIG. 3, the water level detection sensors 250a to 250c will be described in detail. In this embodiment, the water level sensor is composed of three probe rods (250a to 250c). The long and medium length probe rods are paired, and the medium and short length probe rods are paired to measure the water level. If the longest probe detects liquid and the medium probe does not detect liquid, then the level is between the longest probe and the medium probe, that is, it forms a level of H1.

A pair of long and medium length probe rods and a pair of medium and short length probe rods are divided into low and high levels, respectively.

On the other hand, the lower end of the culture tank 200 is preferably formed to be inclined so that the outlet portion is formed to be lower in order to easily discharge the culture material (EM) cultured after the cultivation operation and minimize the residue.

With reference to FIG. 1, the discharge pipe 211 is demonstrated.

Discharge pipe 211 is connected to the lower end of each culture tank to discharge the culture material from the culture tank (200). The discharge pipe 211 is divided into a paper discharge pipe extending from each culture tank 200 and a main discharge pipe to which each paper discharge pipe joins.

The leaf discharge pipe 211 is provided with a separate discharge valve 221 for opening and closing the discharge of the culture material from each culture tank, the main discharge pipe is provided with a main discharge valve 223 for opening and closing the discharge of the culture material from the main discharge pipe.

The main discharge valve 223 is used for discharging the culture material to the outside after the completion of the cultivation work and the individual discharge valve 221 is stirred or other emergency in addition to the use for discharge after the cultivation work is completed to another culture tank (200) It is also open for movement.

The controller (not shown) controls each valve, pump, and the like to control the flow of water and microorganisms, and electrically controls the operation of the mixing tank 100 and the culture tank 200.

In terms of operation, the control unit proceeds the mixing operation, the feeding operation, the culturing operation sequentially, and after the culturing operation, the control of the discharge of the culture material is performed.

In the mixing operation, the mixing apparatus of the mixing tank 100 is controlled to mix the microorganisms and the composite microorganisms introduced into the mixing tank 100.

In the supply operation, the water supply device is operated to supply the mixed microorganisms mixed with water to the culture tank 200, the supply valve 220 is opened, the complex microorganism inlet valve 130 is opened, and the complex microorganism inlet pump 120 is provided. By operating the microorganisms in the mixing tank 100 to flow into the water supply pipe 210. At this time, water and complex microorganisms are generally added at a ratio of about 4: 1.

During the culturing operation, the temperature inside the cultivation tank 200 is maintained at about 35 degrees Celsius suitable for culturing microorganisms for a predetermined period of time through a temperature control device provided in the culture tank 200.

<Example 2>

Example 2 is a case in which the stirring operation in the culture tank 200 is made through a separate stirring tube 212, and in the emergency it is possible to move the culture tank 200 through the stirring tube 212.

With reference to FIG. 2, the stirring tube 212 and its effect are demonstrated.

The stirring tube 212 connects the culture vessel 200 upper portion from the discharge tube 211 below the culture vessel 200. The stirring tube 212 is provided with a stirring pump so as to move the culture material through the stirring tube 212 given a constant pressure and the stirring valve 224 opening and closing the stirring tube 212.

It is assumed that abnormal conditions occur in the culture conditions of the culture tank 200 such as when the temperature inside the culture tank 200 deviates from the proper culture temperature through a temperature sensor of the culture tank 200.

In this case, the controller opens the agitating valve 224 of the normal culture tank side B to move the individual discharge pump 221 and the culture material of the culture tank 200 delivered in an abnormal state by receiving it from a temperature sensor or the like and normal. The stirring pump 225 of the culture tank side (B) is operated to allow the movement of the culture material between the culture tanks.

On the other hand, in the culture operation, even if there is no separate stirring device in the culture tank 200, the stirring operation is made through the stirring tube 212. That is, the controller opens the individual discharge valve 221 and the stirring valve 224 on one side during the culturing operation, and operates the stirring pump 225 to allow the culture material movement in the single culture tank 200.

That is, in Example 2, when the temperature is not suitable for the culture conditions or when the abnormality occurs in the function of the other culture tank 200, the culture tank 200 in the abnormal state from the other culture tank 200 in the normal state inside It is possible to move the culture material, and at the same time through this configuration to make the stirring of the culture material in the usual, there is no need for a separate device for stirring has an economic effect.
