Description

Separation apparatus for organic compound synthesis in upper part of sedimentation tank {APPARATUS FOR SEPARATING AN ORGANIC COMPOUNDS OF THE UPPER PART OF SETTLING TANK}

The present invention relates to an apparatus for purifying various wastewater generated in a tin-plated steel sheet plant in a sedimentation tank, and more specifically, by operating a driving device and a collecting means in the sedimentation tank when organic compound particles are introduced into the sedimentation tank in the neutralization tank. The present invention relates to an organic composite particle separating and treating apparatus for sedimentation tank upper layer which allows particles to be confined and flows down along an inclined surface and rotates the crushing brush to remove the condensed particles and sinks to the lower part of the sedimentation tank during the process.

In general, wastewater generated from tin-plated steel sheet equipment is classified into alkali wastewater used as raw material degreasing solution and acid wastewater, chromic acid, and phenol resin mainly generated in post-treatment processes. Thus, the wastewater transported from different collection tanks is subjected to chemical reactions such as oxidation and reduction depending on the components and then transferred to the neutralization tank. In the neutralization tank, the neutralized water transferred by the wastewater inlet pipe 116 from the neutralization tank 100 to the lower mixing chamber 102 is increased by the operation of the stirrer 104 by the drive motor 118, thereby increasing the mixing efficiency. As the sludge is discharged through the discharge port 106, the supernatant of the sludge is deposited into the lower part and is discharged through the discharge pipe 110 after the flow rate is adjusted through the wear unit 108. At this time, the supernatant is discharged after being adjusted to the environmental standard ph 6 ~ 8 through the sludge discharge pipe (112).

As shown in FIGS. 1 and 2, organic substances in alkaline wastewater generated in tin-plated steel sheets and organic substances in various additives are mixed and transferred to a neutralization tank, where some wastewater is mixed using a hydroxide precipitation method by adding slaked lime. When mixed, they are processed through mutually organic chemical reactions. During this process, traces of oil and organics that are not detected by the chemical analysis cause a synthesis reaction and are entangled with each other as they float to the upper portion of the precipitation tank mixing chamber 102. As the organic compound particles are introduced into the precipitation tank mixing chamber 102 from the neutralization tank, the sludge powder is generally deposited under the conventional precipitation tank 100 by a polymer, which is a polymer flocculant, The phenomenon in which the fine particles are coalesced into the upper layer of the conventional precipitation tank 100 and merges frequently occurs (FIGS. 1B and 1C).

This phenomenon contaminates the entire sedimentation tank, and the worker stirs and beats the rod using a long rod with a brush to decompose the coagulated particles. However, such work takes too much time and the risk of falling down to the bottom of the sedimentation tank is always present, and if the work is not performed in a timely manner, the synthetic particles overflow into the wear part 108 through the bottom of the spill prevention plate 114. There is a problem of over-flow. In addition, not only causes environmental pollution, but also causes a number of problems, such as impossible to treat the waste by the hydroxide precipitation method.

The present invention is to solve the problems as described above, to collect and decompose the aggregated particles synthesized with organic matter in the upper part of the sedimentation tank while operating the collecting means to settle down the sedimentation tank to facilitate sludge transport and dehydration, waste treatment It aims to make it smooth.

Another object of the present invention is to block the organic particles flowing in the wear portion through the bottom of the sedimentation tank leak prevention plate in advance to prevent environmental pollution and to eliminate the separate work of decomposing aggregated particles, thereby improving work efficiency and productivity It is to provide an organic material particle separation treatment apparatus for the upper part of the settling tank that can be planned.
