Description

색도제거조성물 및 이를 이용한 양돈폐수정화방류수의 색도제거방법{chromaticity removal composite and chromaticity removal method of using the Piggery Effluent purify release water} Chromaticity removal composite and chromaticity removal method of using the Piggery Effluent purify release water}

본 발명은 양돈농가에서 폐수를 정화한 방류수의 색도를 저비용과 처리방법으로 짙은 갈색에서 무색으로 탈색함은 물론, 고도의 정화기능으로 청정의 방류수를 방류 및 세척수의 재생성을 가능케 한 색도제거조성물 및 이를 이용한 양돈폐수정화방류수의 색도제거방법을 제공한다.
The present invention is the color removal of the effluent purified from the pig farms to dark brown to colorless by low cost and treatment method, as well as a color removal composition that enables the discharge of clean effluent and regeneration of the wash water with a high purification function and It provides a method for removing color of swine wastewater effluent using the same.

일반적으로 양돈농가의 폐수에 대한 정화는 규모에 따라 간이정화조 또는 생물학적인 처리방법을 통하여 정화한 다음, 이를 하천으로 방류(이하 '방류수' 라고 함)하고 있었다.In general, the wastewater of pig farms has been purified by simple septic tanks or biological treatment methods according to the scale, and then discharged into streams (hereinafter referred to as 'water discharge').

하지만, 상기의 방류수가 법 규제 농도인 수질기준에 이하로 정화된 깨끗한 상태의 방류수임에도 불구하고, 그 색깔이 짙은 갈색을 띄고 있어 인근주민과 많은 갈등을 일으키고 있었다.However, despite the fact that the discharged water is clean water discharged to below the water quality standard, which is a legally regulated concentration, the color is dark brown, causing many conflicts with neighboring residents.

즉, 폐수방류의 오해는 물론, 하천의 물을 혼탁하게 하고, 물고기를 폐사시키게 하는 오염의 주범이 양돈농가로 대부분 인식되고 있었다.In other words, pig farmers have been recognized as the main culprit of pollution, which causes not only misunderstanding of wastewater discharge but also turbid water in rivers and death of fish.

하여, 종래에는 양돈농가에서는 담체, 활성탄, 오존, 여과막 및 멤브레인 등과 같은 방식을 동원하여 방류수의 색도제거를 도모하고 있었다.In the past, pig farms have attempted to remove chromaticity of the effluent using methods such as carriers, activated carbon, ozone, filtration membranes and membranes.

그러나, 상기와 같은 종래의 색도제거 방식들은, 공통적으로 최종폐기물의 처리, 숙달된 전문가의 고용, 소모품의 교체 및 소비, 등의 문제로 유지관리비용 많이 들어가기 때문에, 소규모농가와 같은 경우 이러한 기술을 접목하기엔 경제적 어려움이 뒤따르고 있어 거의 실현이 불가능하였다.
However, such conventional color removal schemes often require high maintenance costs due to problems such as disposal of the final waste, employment of trained professionals, replacement and consumption of consumables, and the like. The economic difficulties to grafting were almost impossible to achieve.

이에 본 발명은 종래와 같은 고도의 처리기술 및 고가의 비용을 들이지 않고도 방류수의 색도를 짙은 갈색에서 무색으로 탈색가능케 함에 그 목적이 있다.
Therefore, the present invention has an object to enable the color of the discharged water to be colorless from dark brown to colorless without having to pay the high-level treatment technology and expensive costs as in the prior art.

상기 목적을 달성하기 위해 본 발명은, PH는 7.5~9.5이며, 성분은 Fe2O3(삼산화이철) 25~45%, Al2O3(산화알루미늄) 15~25%, SiO2(이산화규소) 10~20%, TiO2(산화티탄) 4~10%, 그 외에 소량의 CaO(산화칼슘), Na2O(산화나트륨)가 함유되어 있는 6~10㎛ 입자크기의 적니(red mud) 70~90% 중량과, 3~5㎛ 입자크기의 MgO(산화마그네슘) 30~10% 중량을 혼합한 분말상태의 조성물로 됨을 특징으로 하는 색도제거조성물과, In order to achieve the above object, the present invention has a PH of 7.5 to 9.5, a component of Fe 2 O 3 (ferric trioxide) 25 to 45%, Al 2 O 3 (aluminum oxide) 15 to 25%, SiO 2 (silicon dioxide) 10 to 20%, TiO 2 (Titanium oxide) 4-10%, other small amounts of CaO (calcium oxide), Na2O (sodium oxide), 6 ~ 10㎛ grain size of red mud 70 ~ 90%, 3 ~ 5 A color removal composition, characterized in that the composition of the powder form mixed with 30 ~ 10% by weight of MgO (magnesium oxide) of the particle size,

상기의 색도제거조성물을 양돈폐수를 정화한 방류수 1L당 2.5~5g 투입하여 색도를 제거되도록 한 것을 특징으로 하는 양돈폐수정화방류수의 색도제거방법을 동시에 제안한다.
The chromaticity removal method of pig wastewater clarification effluent, which is characterized in that the color removal composition was added to 2.5 ~ 5g per 1L of effluent clarified the effluent wastewater.

상기와 같이 된 본 발명은, 색도제거조성물의 화학적 성분에 의해 단순히 양돈폐수정화방류수에 일정량 투입만 하여도 화학적 이온교환반응으로 방류수의 색도물질이 색도제거조성물에 흡착/침전되기 때문에, 종래와 같이 고도의 처리기술 및 고가의 비용을 들이지 않고도 방류수의 색도를 짙은 갈색에서 무색으로 탈색가능한 효과가 있다.According to the present invention as described above, since the chromatic material of the effluent is adsorbed / precipitated to the chromate removal composition by chemical ion exchange reaction even by simply putting a certain amount into the swine wastewater effluent by the chemical component of the chromate removal composition, The color of the effluent can be discolored from dark brown to colorless without the need for advanced treatment and expensive costs.

더불어, 본 발명의 색도제거조성물은 색도제거와 동시에 고도의 정화기능을 가지기 때문에 방류수를 세척수로의 재활용이 가능해지는 효과도 있다.In addition, since the chromaticity removal composition of the present invention has a high purification function at the same time as the chromaticity removal, it is also possible to recycle the effluent to the wash water.

따라서, 본 발명은 종래와 같이 방류수의 색도로 인한 인근주민과의 오해와 갈등, 민원, 등을 해소할 수 있어 농가의 신뢰도를 담보할 수 있고, 동시에 저비용으로 청정의 방류수를 방류 및 세척수를 재생성으로 농가의 만족도가 극대화되는 이점을 낳는다.
Therefore, the present invention can resolve misunderstandings, conflicts, complaints, etc. with neighboring residents due to the color of the discharged water as in the prior art to ensure the reliability of the farm, and at the same time to discharge the clean discharged water and regenerate the washed water at low cost This yields the advantage of maximizing the satisfaction of farmers.

도 1은 본 발명의 색도제거조성물을 이용한 양돈폐수정화방류수의 색도제거방법을 나타낸 간략도이다.1 is a simplified diagram showing a method for removing color of swine wastewater purification effluent using the color removing composition of the present invention.

이하 본 발명을 실현하기 위한 구체적인 예를 설명하면 다음과 같다. 다만, 본 발명을 설명하기에 앞서 선행기술 또는 통상의 기술에 대한 구조, 작용, 효과 등은 본 발명의 요지를 흐릴 수 있어 그 상세한 설명은 생략한다.
Hereinafter, a specific example for realizing the present invention will be described. However, prior to describing the present invention, the structure, operation, effects, etc. of the prior art or the conventional art may obscure the gist of the present invention, and thus the detailed description thereof will be omitted.

본 발명의 색도제거조성물(이하 '조성물'로 함)은, 적니(red mud)와, MgO(산화마그네슘)을 혼합한 분말상태의 조성물로 된다.
The color removal composition (hereinafter referred to as 'composition') of the present invention is a powdery composition in which red mud and MgO (magnesium oxide) are mixed.

이때, 상기의 적니(red mud)는, 보오크사이트(Bauxite)로부터 수산화알루미나를 추출한 후, 발생되는 사업장폐기물인 PH13에 달하는 페기적니를 물리화학적으로 변형시켜 PH7.5~9.5되면서, 산 중화능력은 4.5~9.0 moles of acid/kg, 금속 흡착능력은 1000meq/kg 이상, 그리고 성분은 Fe2O3(삼산화이철) 25~45%, Al2O3(산화알루미늄) 15~25%, SiO2(이산화규소) 10~20%, TiO2(산화티탄) 4~10%, 그 외에 소량의 CaO(산화칼슘), Na2O(산화나트륨)로 구성되어 있는 것이 바람직하고, At this time, the red mud extracts alumina hydroxide from bauxite, and then physically chemically modifies the pegyrulli, which reaches PH13, which is the business waste generated, and neutralizes the acid. The capacity is 4.5 ~ 9.0 moles of acid / kg, the metal adsorption capacity is over 1000 meq / kg, and the composition is 25 ~ 45% of Fe2O3 (ferric trioxide), 15 ~ 25% of Al2O3 (aluminum oxide), 10 ~ of SiO2 (silicon dioxide) 20%, TiO 2 (titanium oxide) 4-10%, and other small amounts of CaO (calcium oxide), Na 2 O (sodium oxide) is preferable,

상기의 MgO(산화마그네슘)의 순도는 96%이며 비중은 2.5~3.5이고 포화용액의 pH는 10.3으로 구성되어 있는 것이 바람직하다.
The purity of the MgO (magnesium oxide) is 96%, specific gravity is 2.5 ~ 3.5 and the pH of the saturated solution is preferably composed of 10.3.

본 발명 조성물의 바람직한 혼합은, 상기의 적니(red mud) 70~90% 중량과 MgO(산화마그네슘) 10~30% 중량을 혼합함이 가장 이상적이다.Preferred mixing of the composition of the present invention is ideally mixing 70 to 90% by weight of the red mud and 10 to 30% by weight of MgO (magnesium oxide).

그리고, 본 발명 조성물의 바람직한 분말크기는, 적니(red mud) 6~10㎛, MgO(산화마그네슘) 3~5㎛으로 됨이 가장 이상적이다.In addition, the preferred powder size of the composition of the present invention is red mud 6 ~ 10㎛, MgO (magnesium oxide) 3 ~ 5㎛ is most ideal.

상기의 혼합비율과, 분말크기는 제조, 생산, 원가 대비 물리화학적으로 가장 효과적인 능력을 발휘하는 수치이긴 하지만, 그렇다고 이를 한정하지는 않는다. 즉, 상기의 혼합비율과 분말크기는 처리하고자 하는 대상의 정도나 상태, 등에 따라 달라질 수 있는 것임으로 이러한 수치변환을 위한 기본수치를 제공하는 것이며, 이를 응용하여 여건에 맞는 최적의 상태로 제조 및 조합할 수 있다.
Although the mixing ratio and the powder size are values that exhibit the most effective physicochemical performance compared to manufacturing, production, and cost, the present invention is not limited thereto. That is, the mixing ratio and the powder size may vary depending on the degree or condition of the object to be treated, and thus provide the basic values for the numerical conversion. Can be combined.

이하, 본 발명 조성물의 작용원리를 설명하면 다음과 같다.Hereinafter, the working principle of the composition of the present invention will be described.

본 발명 조성물을 양돈폐수를 정화한 방류수에 투입하게 되면, 적니의 주 구성성분인 Fe2O3(삼산화이철)과 Al2O3(산화알루미늄)의 Fe(철)-Al(알루미늄) 수산화물 그리고 MgO(산화마그네슘)의 Mg(마그네슘)이온이 먼저 물속의 색도유발물질과 이온교환반응이 일어나고 동시에 물속의 PH가 조절되고 반응시간이 경과되면서 흡착(adsorption) 및 침전(precipitation)이 일어나게 된다.When the composition of the present invention is introduced into the effluent clarified effluent, the main components of red mud are Fe (Fe) -Al (aluminum) hydroxides of Fe2O3 (ferric trioxide), Al2O3 (aluminum oxide) and MgO (magnesium oxide). Mg (magnesium) ions first undergo ion exchange reactions with chromatin-causing substances in water, and at the same time, the pH in the water is controlled and the adsorption and precipitation occur as the reaction time elapses.

여기에서, 양돈폐수정화방류수의 색도유발물질들이 본 발명의 조성물과 반응하여 색도물질만 슬러지(sludge) 형태로 가라앉게 되고, 이때 화학적 활성화 반응으로 생성되는 스컴(scum)이 부유하게 되는데, 상기의 슬러지와 스컴을 제거하고 남은 순수 물을 추출하면 색도가 제거된 상태의 청정 방류수가 만들어진다.Here, the color-causing substances of swine wastewater effluent are reacted with the composition of the present invention to sink only the chromatic substance into a sludge form, at which time the scum generated by the chemical activation reaction becomes suspended. When the sludge and scum are removed and the remaining pure water is extracted, clean effluent with chromaticity is removed.

상기의 이온교환반응에서 방류수의 색도유발물질만 슬러지형태로 가라앉는 것이 아니라, 방류수 내의 각종 유해물질도 동시에 흡착/침전되기 때문에 방류수의 생물학적산소요구량(BOD), 화학적산소요구량(COD), 부유물질(SS), 총질소(T-N) 그리고 총인(T-P)을 대폭 낮추어 주어 정화작용도 우수하다.
In the above ion exchange reaction, not only the color-causing substance of the effluent sinks in the form of sludge, but also various toxic substances in the effluent are simultaneously adsorbed and precipitated, so that the biological oxygen demand (BOD), chemical oxygen demand (COD), and suspended solids of the effluent are suspended. (SS), total nitrogen (TN) and total phosphorus (TP) is significantly lowered, the purification is also excellent.

본 발명 조성물은 친환경광물질의 조합으로 매우 미세한 입자의 크기를 가지는 분자들이 부피 비(volum ratio) 대비 높은 표면영역을 가지고, 대부분의 분자들은 질량비(mass ratio) 대비 높은 표면 전하를 가져 조성물의 표면을 극도로 활발하게 하여 전하 입자들 혹은 극성의 분자들을 당기고 보유하는데 탁월한 능력을 가지게 되는데, 본 발명 조성물의 구성에서 단순한 다른 미세한 입자의 물질들도 이런 능력이 있으나, 본 발명의 조성물은 20여 가지의 다양한 광물질로 구성되어 활성도가 매우 높은 광물질들의 혼합물이라는데 있다. The composition of the present invention is a combination of environmentally friendly minerals, molecules having a very fine particle size has a high surface area compared to the volume ratio, most molecules have a high surface charge compared to the mass ratio to provide a surface of the composition It is extremely active and has an excellent ability to attract and retain charged particles or polar molecules, although other fine particle materials that are simple in the composition of the present invention have this ability, but the composition of the present invention has more than 20 It is composed of various minerals and is a mixture of minerals with high activity.

이렇게, 활성도가 매우 높은 광물질들의 혼합물은, 넓은 범위의 PH환경들(PH 3~10)에 걸쳐서 일부는 음성적으로 전하를 띨 것이며, 반면에 다른 것들은 양성적으로 전하를 띠게 되는데, 이러한, 전하들은 대개 극성의 분자들보다 좀 더 강하게 지속 되어 더 큰 분자들은 더 작은 분자들보다 더 강하게 지속 된다. Thus, mixtures of highly active minerals will be negatively charged in some over a wide range of PH environments (PH 3-10), while others will be positively charged. It is usually more intense than polar molecules, so larger molecules are stronger than smaller molecules.

하여, 물 이외에 포함되어 있는 각종 유해물질들을 본 발명 조성물의 광물입자표면(solid mineral particles)에 흡착이 이루어져 침전, 치환으로 제거되는 것이다.
Thus, various harmful substances contained in addition to water are adsorbed on the surface of solid mineral particles of the composition of the present invention, and are removed by precipitation and substitution.

이하, 본 발명 조성물을 이용한 양돈페수의 색도제거방법을 설명하면 다음과 같다.Hereinafter, the method for removing color of swine wastewater using the composition of the present invention will be described.

먼저, 상술한 바와 같이, 본 발명의 조성물은 양돈폐수를 정화한 방류수에 적용함이 가장 이상적이다.First, as described above, the composition of the present invention is most ideally applied to the effluent clarified effluent.

이를 감안하여 설명하면, 본 발명 조성물을, 양돈폐수를 정화한 방류수 1L당 2.5 ~ 5g 정도 투입하는 것이 가장 이상적이며, 이렇게 일정량 투입만 하여도 방류수의 색도를 탈색은 물론 정화의 효과가 있다.
In consideration of this, it is most ideal to inject about 2.5 to 5g of the composition of the present invention per 1L of effluent clarified effluent wastewater, and even a certain amount of the effluent is used to purify the chromaticity of the effluent as well as to purify it.

그러나, 상기에서 본 발명의 조성물을 양돈폐수정화방류수에 투입한 다음, 물리적/화학적 반응의 활성화를 도모하면, 더욱 신속하고 효율적인 처리가 가능해진다.
However, when the composition of the present invention is added to the swine wastewater effluent and then the physical / chemical reaction is activated, more rapid and efficient treatment is possible.

이에, 상기의 물리적/화학적 반응의 활성화를 도모하기 위한 바람직한 처리방법을 첨부도면과 함께 설명하면 다음과 같다.Thus, the preferred treatment method for the activation of the physical / chemical reaction described above with reference to the accompanying drawings.

① 본 발명의 조성물을 양돈폐수를 정화한 방류수 1L당 2.5 ~ 5g 투입한 방류수를 제1반응조에 담아 물리적 교반으로 반응을 활성화시킨다.① Put the composition of the present invention in 2.5 ~ 5g per 1L of effluent clarified effluent in the first reactor to activate the reaction by physical stirring.

② 그 다음, 상기의 방류수를 제2반응조로 이송공급 후, 방류수 1L당 물 100% 중 38%의 FeCl3(염화제이철)을 희석한 PH유지제 1.5 ~ 3.4㎖를 투입하여서 화학적 반응을 활성화시킨다.② Then, after supplying the discharged water to the second reaction tank, 1.5 ~ 3.4mL of PH retaining agent diluted with 38% FeCl 3 (ferric chloride) in 100% of water per 1L of discharged water is added to activate the chemical reaction.

③ 상기와 동시에 제2반응조에 방류수 1L당 0.1%의 음이온성 고분자응집제(A-730PH)를 투입하여서 응집시킨다.③ At the same time as above, in the second reactor, 0.1% of anionic polymer coagulant (A-730PH) per 1L of effluent is aggregated.

이렇게 하면, 단순히 본 발명 조성물을 양돈폐수정화방류수에 일정량 투입한 것에 비해 시간적, 공간적, 한계를 효과적으로 개설할 수 있다.
By doing so, it is possible to effectively establish the temporal, spatial and limitations of the present invention as compared with simply adding a certain amount of the present invention to swine wastewater effluent.

상기의 바람직한 처리방법에 대해 부연설명을 하면, ①에서 방류수를 제1반응조에 담아 물리적 교반으로 반응을 활성화하는 것이 가장 바람직하나 이를 한정하지 않는다. 즉, 다른 예로 방류수를 제1반응조에 담지 않고 수로를 통해 연속이송시킬 수도 있고, 수로 상에 요철돌기나 단차에 의해 출렁이게 할 수도 있다. 이는 궁극적으로 본 발명의 조성물과 양돈폐수정화방류수의 원활한 혼합을 위한 것이므로 상기의 혼합의 효율성을 달성하기 위한 모든 수단이면 된다.In the above description of the preferred treatment method, it is most preferred to activate the reaction by putting the effluent water in the first reaction tank in ① and physical stirring, but not limited thereto. That is, in another example, the effluent may be continuously transported through the water channel without being contained in the first reactor, or may be swung by irregularities or steps on the waterway. This is ultimately intended for the smooth mixing of the composition of the present invention and the swine wastewater effluent and may be any means for achieving the above mixing efficiency.

또한, 상기에서 본 발명의 조성물을 양돈폐수정화방류수에 일정량 공급하게 되는데, 이때 양돈폐수정화방류수를 제1반응조에 담고, 제1반응조에 담겨진 량을 감안하여 한꺼번에 본 발명의 조성물을 투입할 수도 있으나, 더 바람직하게는 양돈폐수정화방류수를 현장에서 연속적으로 처리하기 위하여 색도제거조성물공급조를 설치하여 유량을 감안한 상태로 정량공급되도록 하는 것이 이상적이다. In addition, the composition of the present invention is supplied to a certain amount of pig wastewater effluent effluent, in which case the pig wastewater effluent effluent is contained in the first reaction tank, in consideration of the amount contained in the first reaction tank may be added to the composition of the present invention at once. More preferably, in order to continuously treat the swine wastewater effluent from the field, it is ideal to install a color removal composition supply tank so that it can be quantitatively supplied in consideration of the flow rate.

상기와 같은 예는 하기에도 마찬가지로 적용됨으로 더 이상의 중복되는 설명은 생략한다.
As the above example is also applied to the following, further overlapping description is omitted.

②에서 투입되는 PH유지제는, 양돈폐수정화방류수의 PH가 일반적으로 8부근으로 중화된 적니를 구성하고 있는 Fe2O3(삼산화이철)과 Al2O3(산화알루미늄)의 Fe(철)-Al(알루미늄) 수산화물의 활성도를 높여주는 역할을 한다. The PH holding agent added in (2) is Fe (Or) -Al (Aluminum) hydroxide of Fe2O3 (ferric trioxide) and Al2O3 (aluminum oxide), which constitutes red mud, which is generally neutralized to around 8. It increases the activity of the.

하여, PH유지제를 투입하게 되는데, 상기 PH유지제는 FeCl3(염화제이철)이 가장 바람직하나, 이에 한정하지 않는다. 즉, 본 발명의 조성물에 의한 PH유지와, 활성화 반응 및 생태환경에 해를 끼치지 않는 모든 물질이면 된다.
In this case, the PH retaining agent is added, but the PH retaining agent is most preferably FeCl 3 (ferric chloride), but is not limited thereto. That is, any substance that does not harm the PH maintenance, the activation reaction and the ecological environment by the composition of the present invention may be used.

③에서 투입되는 음이온성 고분자응집제(A-730PH)는, 본 발명의 조성물과 양돈폐수정화방류수 간의 반응으로 흡착/침전된 것을 빠르게 응집시켜 슬러지형태로 가라앉게 한다. 상기 음이온성 고분자응집제도 상술한 바와 마찬가지로 한정구성이 아니라 반응의 촉진, 응집 효율성을 감안한 모든 물질이면 된다.
The anionic polymer coagulant (A-730PH) introduced in (3) rapidly aggregates the adsorbed / precipitated by the reaction between the composition of the present invention and the swine wastewater effluent to sink into a sludge form. As described above, the anionic polymer agglomerate may be any substance in consideration of the promotion of the reaction and the aggregation efficiency, rather than a limited configuration.

상기의 ③이후에는 첨부도면에 도시된 바와 같이, 제2반응조의 방류수를 침전조로 이송공급 후, 침전 한 다음, 다시 여과조로 이송공급 후, 여과한 다음 방류하면 된다.After the above ③, as shown in the accompanying drawings, the effluent water of the second reaction tank is transferred to the settling tank, then settled, and then fed back to the filtration tank, filtered and then discharged.

이때, 침전조에는 고분자응집제에 의한 반응으로 침전되는 슬러지를 펌프 등을 통하여 집수조에 저장하고, 여과조는 화학적반응으로 생성되는 스컴을 걸러내어서 제거한 다음, 이물질이 포함되지 않는 순수 방류수만 방류한다.At this time, the sedimentation tank stores the sludge precipitated by the reaction with the polymer flocculant in the water collecting tank through a pump or the like, and the filtration tank filters and removes the scum generated by the chemical reaction, and then discharges only the pure effluent not containing foreign substances.

상기에서 발생되는 슬러지나 스컴은 종래의 처리방식에 비해 훨씬 적은 량이 발생됨으로써 처리의 효율성 및 비용을 대폭 절감할 수 있다.
Sludge or scum generated in the above is generated much less than the conventional treatment method can significantly reduce the efficiency and cost of the treatment.

상기의 전 처리과정에서 반응조와 반응조 사이에 방류수의 이송공급은 반응조의 중간위치에 입/출관을 위치시켜 펌프로 이송공급함이 가장 바람직하나, 구간에 따라 수로, 덕트, 등으로 가능하고, 이송공급시 구간에 따라 낙차나 물리적 교반을 병행하면서 수행할 수도 있고, 전 처리과정 및 각 구간에 필요한 구성은 전체적인 공간이나, 비용, 인력에 따라 자동화 또는 수동화의 선택으로 다양하게 시설, 설비, 장치, 등을 마련하여 구현할 수 있다. 하여, 본 발명에서는 색도제거방법만 제시할 뿐이며, 이를 응용한 수단은 다양하게 수정 및 변경할 수 있는 것임으로 한정하지 않는다.
In the pretreatment process, the supply of effluent water between the reaction tank and the reaction tank is most preferably to be supplied to the pump by placing an inlet / outlet pipe at an intermediate position of the reactor, but depending on the section, it is possible to supply water, a duct, and the like. Depending on the time zone, dropping or physical agitation may be performed in parallel, and the pre-processing process and the configuration required for each section may be carried out in various ways depending on the overall space, cost, and manpower. And the like can be implemented. Thus, the present invention only suggests a method for removing color, and means for applying the same is not limited to various modifications and changes.
