Description

Wastewater Purification System {A WASTE WATER DISPOSAL PLANT}

The present invention relates to an apparatus for purifying wastewater, and more particularly, to a wastewater purifying apparatus capable of effectively purifying a large amount by allowing wastewater to be purified while being sequentially passed through a comprehensive tank, a sedimentation tank, an aeration tank, and an anaerobic tank. will be.

In general, in order to clean various livestock breeding grounds, manure and dirt can be sprinkled as water, and when the wastewater generated at this time is discharged into rivers, it becomes the root cause of water pollution. There is a situation.

Conventional wastewater purification apparatuses have been developed as devices for sorting manure of livestock contained in the wastewater and as devices for purifying wastewater from which manure has been removed.

First, a conventional apparatus for sorting manure of livestock is equipped with a belt conveyor equipped with upper and lower zigzag, while waste water is passed through each belt conveyor from the belt conveyor at the highest level, water is removed and only manure is sorted. Will be.

However, the sorting device of the livestock manure is expensive to manufacture each belt conveyor because the appearance is expensive, the space occupied by the device had to be large. In particular, the manure of selected livestock can be recycled, but the wastewater from which manure has been removed is contaminated and thus discharged into rivers, causing river pollution.

In addition, when looking at the wastewater purification apparatus using conventional microorganisms, the anaerobic tank, aeration tank, and sedimentation tank are installed separately, and the wastewater enters the anaerobic tank, and after the sedimentation and anaerobic decomposition is performed, the wastewater is introduced into the aeration tank. As the organic material is decomposed by the organic matter, the organic material is removed and then introduced into the sedimentation chamber. The wastewater introduced into the sedimentation chamber is discharged to the outside through the outlet of the upper part after the remaining sludge is precipitated by the weight and the treatment is completed. The outflow process is performed sequentially.

However, this means that the treatment time is delayed because the manure contained in the wastewater must be treated together. When the wastewater enters the anaerobic tank, a large amount of manure is settled on the floor, so that anaerobic decomposition is not properly performed. The purification efficiency is reduced by moving to the next process, and in order to process a large amount of manure in a short time, the capacity of the apparatus must be manufactured in a large size, but there is a difficult problem in raising the manufacturing cost and securing the installation space. The manure of the livestock was processed together and it could not be recycled in rural areas.

In addition, the aeration tank is provided with an air supply pipe through which air is supplied to the inflow shaft therein, and the purification efficiency per unit volume is insufficient. That is, in order to decompose organic materials by aerobic microorganisms present in the aeration tank, a sufficient amount of processing time is consumed along with supply of sufficient air, but the aeration tank by conventional means is the entire wastewater contained therein. Since air is supplied by a single air supply pipe, sufficient air supply is not provided, and wastewater introduced into the aeration tank is discharged to the outlet formed at the upper part through the inlet formed at the upper part of the aeration tank, so the delay time in the interior is short. And insufficient contact with air has been raised as an untreated state to be discharged to the next stage.

Therefore, the means for sorting the manure of the livestock and the means for purifying the wastewater are treated separately, and the means for sorting the manure of the livestock should be purified as a separate means since the wastewater is not purified. As a means for purifying the wastewater, there has been a problem of delayed and increased doses between treatment companies since manure is not purified.

The present invention has been researched and developed in order to solve the above problems, in order to purify the wastewater generated in the livestock use, the synthesis tank, sedimentation tank, aeration tank, anaerobic tank in order to sequentially, the livestock manure dehydration in the synthesis tank The purpose of this is to increase the treatment efficiency by discharging the waste to outside and to recycle the livestock manure as fertilizer.

Another object of the present invention is to configure each circulation chamber in the aeration tank to supply sufficient air while the wastewater introduced into the aeration tank is transferred to each circulation chamber, and at the same time, decompose organic substances by microorganisms and purify them. To increase the efficiency.

Referring to the effects of the present invention configured as described above are as follows.

In general, wastewater generated in a livestock farm is a state in which manure of livestock is mixed with water, and this wastewater is introduced into the integrated tank (C) through the inlet pipe (3).

That is, the wastewater flowing into the synthesis tank C is first introduced into the first precipitation chamber 2a and then moved to the second precipitation chamber 2b through the lower circulation passage 5, where the wastewater is first precipitated. The livestock manure contained during the retardation in the seal 2a is settled on the bottom surface by weight and moved to the second sediment 2b. The wastewater collected at the bottom of the first settling chamber 2a and moved to the top of the second settling chamber 2b is introduced into the settling tank R through the passage T ₁ .

The livestock manure deposited on the bottom surface of the first settling chamber 2a is discharged to the outside after water is removed while being transported by the manure discharge member 6, and the screw shaft 6b returned by the motor 8 is removed. The livestock manure is dehydrated during the transfer to the upper part, and after the water is removed to the dehydration hole 6c, the manure is discharged downward through the manure discharge pipe 7 and is prepared in advance on the manure collection bag 42 to be loaded on the clouding member 41. Since it is contained, it can be used as a fertilizer by collecting a certain amount of the bag for collecting manure 42.

In addition, an appropriate amount of fermentation liquid is introduced into the wastewater from the fermentation solution input member 43 installed above the first precipitation chamber 2a, and in order to satisfy the fermentation conditions by the fermentation broth, the first precipitation chamber 2a and the second precipitation It is preferable to keep the seal 2b in a vacuum state. Therefore, the air inside the first precipitation chamber 2a is exhausted to the outside by the air pump 44, and the vacuum inside the second precipitation chamber 2b is maintained by the opening / closing member 13.

That is, the opening and closing member 13 is located in the sedimentation tank (R), so that the water pressure due to the waste water of the sedimentation tank (R) and the elasticity of the spring (13b) is maintained in a closed state at the end of the passage (T ₂ ) When the water pressure is increased while the water level of the second precipitation chamber 2b is increased, the opening / closing member 13 is opened while rotating from the support shaft 13a as a starting point, so that the inside of the second precipitation chamber 2b is always maintained in a vacuum state.

The wastewater flowing into the sedimentation tank R is purged with fermentation at the same time as the sludge of the relatively small particles contained during the retardation settles to the bottom by its own weight. At this time, the sludge precipitated in the sludge collection unit 11 of the bottom surface is recovered to the comprehensive tank (C) through the sludge discharge pipe (12).

The wastewater purified in the settling tank R is moved to the aeration tank A through the passage T ₂ formed at the upper portion.

Wastewater introduced into the aeration tank A is moved from the first aeration chamber 22a to the second aeration chamber 23a through the lower circulation path 23a, and then through the upper circulation path 23b, the third aeration chamber ( It is transferred to 23c) and again to the fourth aeration chamber 24d through the lower circulation tank 23c and then to the anaerobic tank B through the upper passage T ₃ .

That is, while the wastewater in the aeration tank A moves to the upper and lower zigzag, there is a sufficient delay time for the decomposition of organic substances by the aerobic microorganisms during the aeration chambers 22a, 22b, 22c, and 22d. Since the inclined plate 26 is formed in each of the diaphragms 21a, 22b, 22c, and 22d, sufficient contact is made by the inclined plate 26 to which aerobic microorganisms are attached.

In particular, air is supplied from the injection ports 24a, 24b, 24c, and 24d provided below each of the aeration chambers 22a, 22b, 22c, and 22d to promote activation of aerobic microorganisms.

Therefore, the wastewater in the aeration tank A may increase the effect of decomposing the organic substances by the microorganisms per unit time due to the delay of the delay time due to the movement of the upper and lower zigzag, the sufficient contact area with the aerobic microorganisms, and the sufficient supply of air. It can be.

The wastewater introduced into the anaerobic tank B is discharged to the outside through the discharge pipe 31 equipped with the opening / closing valve 32 after the purification process such as nitrogen removal is performed for a certain time delay.

Wastewater in the anaerobic tank (B) is to control the delay time by the on-off valve 32, by selectively controlling the opening time by operating the on-off valve 32 with an electrical signal from the outside in accordance with the inflow amount or treatment degree of the wastewater The effect of the purification time can be increased.

As described above, the present invention, in the treatment of wastewater generated in a livestock farm, by first dehydrating the livestock manure after draining to the outside to increase the purification efficiency and to recycle the livestock manure, inflow into the aeration tank Sufficient air is supplied while the wastewater is moved to the upper and lower zigzag to promote the activation of microorganisms, thereby increasing the purification efficiency per unit time.

The present invention is an advantageous invention that can be efficiently applied to the purification of all wastewater generated in a general home or restaurant as well as wastewater generated in a livestock farm.
