Description

Method for disposing of liquid waste and apparatus for performing the same {method for disposing of liquid waste matters and apparatus for performing the same}

The present invention relates to a liquid waste treatment method for purifying water quality contaminated by contaminants such as waste oil, organic solvents, organic chemicals, and the like, and an apparatus for performing the same.

With industrialization, water resources are extremely polluted by factory liquid waste and domestic sewage. To some extent contaminated water quality has been purified by organic microorganisms, but recently, malignant organic contaminants have increased and eutrophication has intensified. As a result, the growth of microorganisms is relatively reduced, and the water quality cannot perform any self-cleaning at all.

To solve this problem fundamentally, the polluted water discharged from industrial facilities such as factories should be purified.

As a method for removing liquid waste in water, oil-water separation, pyrolysis, hot incineration, and hot melting are provided.

Conventional oil-water separator is sprayed to separate by using the specific gravity difference between water and oil, the degree of separation is not accurate, but can only separate the oil floating in the water and the organic solvent or organic chemicals mixed in the particulate state in the water Cannot be separated. In addition, since the specific gravity of water and oil is used, the process time is delayed because the oil has to wait for a predetermined time or more until the oil is sufficiently floated on the water.

Pyrolysis, hot incineration, and hot melt can be expected to have a treatment effect, but they require a heating device and an energy source for heating, so the initial installation and maintenance costs of the device are relatively expensive, and another environment associated with heat treatment and incineration. It can cause pollution and there is a problem that organic waste can not be recycled. And oils which are easily separated from water among the pollutants contained in liquid waste can be easily removed by any method, but pollutants that are easily dissolved and mixed in water such as organic solvents and organic chemicals, have many processes. The pollutants to be separated must be disposed of regardless of whether they are recycled or not, which is undesirable in terms of recycling resources.

Liquid waste treatment systems must consider aspects that are fundamentally inexpensive to install and maintain, safe and fast, with sufficient disposal capacity, with the potential to reduce other environmental pollutants, and recycle resources.

In the present invention, when the sludge is included in the liquid waste, the sludge may be removed, and then water and waste may be separated and treated according to environmental standards.

In addition, the present invention is to filter the waste by stirring with the adsorbent, and then to test and re-examine the discharged water and waste to be reprocessed, it is possible to treat or recycle the completely separated water and waste in accordance with environmental standards.

By doing so, the present invention is significantly cheaper to manufacture the device than oil-water separation, pyrolysis, high temperature incineration, and high temperature melting, and can exhibit the same processing efficiency as other methods except for high temperature incineration, which exhibits relatively high processing efficiency. While there is no heat generated by energy use, secondary pollution and energy consumption problems can be solved.

In addition, the present invention facilitates contaminants that have to undergo many treatment processes, such as oils that are easily separated from water among contaminants contained in liquid waste, organic solvents that are easily dissolved and mixed in water, and organic chemicals. Anything that can be separated from water and recycled in separated organic solvents, organic compounds, organic chemicals, etc. can be reused.

In addition, the adsorbent used in the present invention may be used continuously when treating the same kind of liquid waste.

The apparatus of the present invention configured as described above looks at the process of treating liquid waste.

In the following description, a number of valves installed in the pipeline of the system do not enumerate their open / close states for the purpose of a simple and clear understanding of the system. This means that when a liquid is being transported from one element to another branch or return line connected to another element, the valve formed at that branch or return line is open and connected to other elements around it. It is understood that the valve installed in the branch pipe or the return pipe is closed.

The liquid waste transported and stored in the storage tank (1) is tested for acidity or alkalinity of the liquid waste before being transferred to the stirring tank (2) or the filtration and compression tank (3). It is then sorted and transported according to the presence of sludge.

In other words, the treatment of liquid waste proceeds differently depending on the amount of sludge and liquid waste of the liquid waste.

Specifically, if the sludge is excessive in the liquid waste transported to the storage tank (1) is laid a filter net () to filter the sludge inside the filtration and compression tank (3), the pump (P1) While driving, the branch pipe 11 facing the stirring tank 2 is closed, and when the branch pipe 12 facing the filtration and compression tank 3 is opened, the liquid waste does not pass through the stirring tank 2 in the storage tank 1. Directly sent to the filtration and compression tank (3), the sludge is caught in the filter net, the liquid waste will naturally fall and fall to the flow test tank (5). At this time, the discharge pipes 31 and 32 of the filtration and compression tank 3 are closed, and another discharge pipe 30 is open.

Filtration and compression tank (3) is selectively installed in accordance with the treatment process to remove the sludge flowing directly from the storage tank (1) and to remove the waste solidified by the adsorbent in the stirring tank (2) according to the treatment process The sludge caught on the filtration net of the filtration and compression tank 3 is treated according to the sludge treatment regulations.

Sludge is removed from the sludge filter net and the treated water supplied to the flow test tank (5) contains a large amount of oil. This treated water is analyzed by a test and the amount of sludge is exceeded. Drive (P5) to supply to the filtration and compression tank (3) through the branch pipe (52), and to the adsorption tank (110) if the non-aqueous waste is contained.

The adsorption tank 110 checks the separation state of the water and the non-aqueous waste by using a measurement meter 111, and then enters the adsorbent and then removes the waste and the adsorbent adsorbed on the water. Processed by supplying to (3) and the remaining water is supplied to the water storage tank (9) through the branch pipe 115 by driving the pump (P9).

The treated water supplied to the water storage tank 9 is filtered by the heavy metal, sludge and residual liquid waste in the form of particulates in the first filter 7 and then discharged to the water storage tank 9 to be treated according to environmental treatment standards.

In addition, when the treatment of the oil from the storage tank (1) to be prior to the treatment of the sludge, put the liquid waste in the storage tank (1) and open the branch pipe (11) facing the stirring tank (2), filtration and compression tank (3) After closing the branch pipe 12 toward) and driving the pump P1, the liquid waste is supplied to the stirrer (2), and the adsorbent corresponding to about 5 to 15 weight of the weight of the liquid waste excluding water from the liquid waste is stirred. Put in (2) and stir using power.

When the stirring tank 2 is sufficiently stirred, the filtering and pressing tank 3 is provided with a filtering net to remove the adsorbent, and then sent to the filtering and pressing tank 3 by using a pump (P2).

When the stirring tank 2 has no sludge in the liquid waste and water-soluble waste is mixed, that is, when the amount of liquid waste is large compared to the amount of water when the water and liquid waste are not separated by specific gravity, the adsorbent is added and stirred. Silver is not adsorbed to the adsorbent, and only the pure liquid waste stock solution is adsorbed to solidify the liquid waste.

Adsorbents are common in liquid waste treatment and convert liquid waste into solids.

Filtration and compression tank (3) is selectively installed in accordance with the treatment process to remove the sludge flowing directly from the storage tank (1) and to remove the waste solidified by the adsorbent in the stirring tank (2) according to the treatment process do.

That is, as described in the former, when the liquid waste has a lot of sludge and is directly transferred from the storage tank 1 to the filtration and compression tank 3, a sludge filtration network for removing the sludge is installed, and the water-soluble liquid waste as described in the latter description. In many cases, when the adsorbent treatment is performed in the stirring tank 2, an adsorbent filter network for removing the solidified waste is provided.

The treated water supplied from the stirring tank (2) to the filtration and compression tank (3) leaves the adsorbent in the adsorbent filter network and falls into the water storage tank (4).

At this time, the discharge pipes 30 and 32 of the filtration and compression tank 3 are closed, and the branch pipe 31 is in an open state.

When the water supplied to the water test tank 4 is tested and determined to be proper, heavy metals, sludge, and residual liquid waste, which are particulates, are filtered out of the first filter 7 through the discharge pipe 40 and the branch pipe 41. Then, it is discharged into the water storage tank 9 and treated according to environmental treatment standards.

At this time, if the test analysis is inadequate, the branch pipe 41 is closed in the discharge pipe 40, and another branch pipe 42 is opened and supplied to the adsorption tank 110.

The result of the inappropriate test analysis is a case where the water and oil are separated by the difference in specific gravity of the water and the oil, such as the non-aqueous liquid, and the adsorbent is added by checking the separation state from the adsorption tank 110 to the measurement meter 111, The absorbed adsorbent is removed, and the extracted adsorbent is supplied to the filtration and compression tank 3 for treatment, and the remaining water is supplied to the water storage tank 9 through the branch pipe 115 by driving a pump P9. Dispose of in accordance with environmental standards.

In this case, if necessary, the discharged water may be repeatedly sent to the stirring tank 2 or the filtration and compression tank 3 through the branch pipes 113 and 114.

In this way, the water from the filtration and compression tank (3) falls into the water test tank (4) without a force, and only the adsorbent remains in the adsorbent filter network, and after the water is sufficiently drained from the adsorbent filter network as described above, the valve (30) (31) , The valve 32 is opened, and the adsorbent filter net in the filtration and compression tank 3 is compressed with a press or centrifuged with a centrifuge to remove liquid wastes except the water adsorbed in the adsorbent to the liquid waste test tank 6. Supplied.

On the other hand, the non-aqueous liquid waste separated by the adsorbent in the adsorption tank 110 is also transferred to the filtration and compression tank (3) to be compressed and dewatered.

Thus, the liquid waste generated by dehydrating the adsorbent is analyzed in the liquid waste test tank (6). If it is determined that there is other waste, the branch pipe (60) of the discharge pipe (60) is closed according to the degree of contamination. The pump P6 is selectively recovered through the recovery pipe 61 to the storage tank 1, the stirring tank 2, or the filtration and compression tank 3 to undergo an iterative treatment process. On the contrary, the return pipe 61 is closed and the branch pipe 60 is opened and discharged to the waste storage tank 100.

The liquid waste supplied to the waste storage tank 100 passes through the second filter 8 installed at the inlet of the waste storage tank 100, and removes foreign substances mixed with particulate heavy metals and oil to be in a state capable of being recycled.

Therefore, the waste stored in the waste storage tank 100 is recycled or treated according to environmental standards.

First, the present invention described above can safely and accurately separate liquid waste from water.

Second, a large amount can be processed at a low cost in a short time.

Third, liquid waste can be recycled.

Fourth, the adsorbent can be reused when treating the same kind of liquid waste.

Fifth, there is no concern about pollution caused by not using heat.

Sixth, water-soluble organic substances mixed with water that are difficult to treat in a liquid state can be separated and incinerated or recycled.
