Description
본 발명은 염색폐수 처리방법과 그 장치에 관한 것으로서, 보다 상세하게는 균질의 농도를 갖게하는 물리적 처리단계, 또는 고농도의 산소공급이 이루어지게 하는 생물적 처리단계, 또는 펜톤(Fenton) 산화처리에 의한 화학적 처리단계, 또는 이들이 조합된 복합 처리방식에 의해 염색폐수 처리방법과 그 장치에 관한 것이다.The present invention relates to a method for treating wastewater and dyeing apparatus, and more particularly, to a physical treatment step having a homogeneous concentration, or a biological treatment step for high oxygen supply, or Fenton oxidation treatment. The present invention relates to a dyeing wastewater treatment method and apparatus by a chemical treatment step or a combination treatment method thereof.
일반적으로 염색폐수를 정화하는 처리방법은 물리적 처리단계와 생물학적 처리단계 및 화학적 처리단계를 적당히 조합하여 복합적으로 처리한다.In general, a treatment method for purifying dyeing wastewater is a complex treatment by combining a combination of physical treatment, biological treatment and chemical treatment.
상기한 물리적 처리단계에서는 균질조에 원수가 일정시간 체류하게 하여 원수의 양과 질 및 농도분포를 균일하게 조절하여 후속 단계로 유통시킨다.In the above physical treatment step, the raw water stays in the homogeneous tank for a certain time to uniformly control the quantity, quality and concentration distribution of the raw water and distribute it to the next step.
이와 같은 물리적 처리단계를 거친 원수는 생물학적 처리단계와 화학적 처리단계, 또는 화학적 처리단계와 생물학적 처리단계를 차례로 거치거나 그 중 어느 하나의 처리단계로 정화시킨다.Raw water that has undergone such a physical treatment step is purified through a biological treatment step and a chemical treatment step, or a chemical treatment step and a biological treatment step, or any one of them.
상기한 바와 같은 생물학적 처리단계는 원수에 공기를 투입하여 공기중의 산소를 미생물의 호흡에 필요한 용존산소로 공급함으로써, 미생물의 번식량을 늘려보다 많은량의 미생물에 의한 오염물질 분해에 따라 원수의 정화율을 극대화시킨다.In the biological treatment step as described above, by supplying air to the raw water and supplying oxygen in the air to the dissolved oxygen necessary for the respiration of the microorganisms, the growth of the microorganisms is increased, so that Maximize the purification rate.
이때 생물학적 처리단계에 있어서 공기 투입에 의한 용존산소 포화량은 보통 20℃에서 9mg/ℓ 이다.At this time, the dissolved oxygen saturation amount by air input in the biological treatment step is usually 9 mg / L at 20 ℃.
또한 상기한 화학적 처리단계에서는 보통 과산화수소(H2O2), 치아염소산소다(NaCl0), 오존(O3) 등을 원수에 투입하여 원수에 함유된 오염물질을 산화시키는 일반적인 산화법이 이용된다.In addition, in the chemical treatment step, a general oxidation method is usually used in which hydrogen peroxide (H 2 O 2 ), sodium hypochlorite (NaCl 0), ozone (O 3 ), etc. are added to raw water to oxidize contaminants contained in the raw water.
그런데, 상기한 바와 같이 염색폐수를 원수로 하여 이 원수를 정화하기 위한 종래의 염색폐수 처리방법은 물리적 처리에 있어서, 최소한 6 시간 동안의 체류시간을 충족시키는 수단이 마련되어 있지 않아 원수의 균질성을 확보할 수 없는 단점이 있다.However, in the conventional dyeing wastewater treatment method for purifying the raw water using the wastewater as raw water as described above, in the physical treatment, there is no means for satisfying the residence time for at least 6 hours, thereby ensuring homogeneity of raw water.

한편, 화학적 처리에 있어서는 일반적인 산화법에 의해 난분해성의 오염물질을 충분히 산화시킬 수가 없기 때문에 원수 정화효과의 극대화를 기대할 수 없는 단점이 있다.On the other hand, in chemical treatment, since it is not possible to sufficiently oxidize hardly degradable contaminants by a general oxidation method, there is a disadvantage in that maximization of the raw water purification effect cannot be expected.
본 발명은 상기한 바와 같은 종래의 단점을 해소하기 위하여 안출된 것으로서, 본 발명의 목적은 원수의 체류시간을 연장시켜 원수의 균질성을 확보하고, 고농도의 순산소를 투입하여 산소의 용존량을 증대시켜 미생물의 호흡에 필요한 용존 산소량을 충분히 확보하게 함으로써, 미생물의 번식을 극대시키고, 펜톤산화법에 의해 원수에 함유된 난분해성의 오염물질을 충분히 산화시켜 원수 정화효과의 극대화를 기대할 수 있게 하는 물리적 처리단계, 또는 생물학적 처리단계, 또는 화학적 처리단계 등 이들이 복합적으로 조합된 염색폐수 처리방법과 그 장치를 제공하는데 있다.The present invention has been made to solve the above-mentioned disadvantages, the object of the present invention is to extend the residence time of the raw water to ensure the homogeneity of the raw water, and to increase the dissolved dissolved oxygen by adding a high concentration of pure oxygen By ensuring sufficient dissolved oxygen for breathing of microorganisms, maximizing the propagation of microorganisms, and fully oxidizing the hard-degradable contaminants contained in raw water by Fenton's oxidation method to maximize the water purification effect.

한편, 상기한 침전조(80)의 하부에는 슬러지 펌프(82)를 연통 형성하여 슬러지펌프(82)의 회전 작동에 따라 침전조(80)에서 정화된 원수로 부터 고액 분리된 고형 침전물, 즉 슬러지를 흡입함으로써, 이 슬러지를 침전조(80)로부터 배출시킨다.On the other hand, the lower portion of the settling tank (80) is formed in communication with the sludge pump 82 in accordance with the rotation operation of the sludge pump 82, solid solids separated from the raw water purified in the settling tank (80), that is, sludge suction As a result, this sludge is discharged from the settling tank 80.
상기한 바와같은 본 발명에 의한 염색폐수 처리방법과 그 장치는 원수의 체류시간을 연장시켜 원수의 균질성을 확보하고, 고농도의 순산소를 투입하여 산소의 용존량을 증대시켜 미생물의 호흡에 필요한 용존 산소량을 충분히 확보하게 함으로써, 미생물의 번식을 극대화시키고, 펜톰산화법에 의해 원수에 함유된 난분해성의 오염물질을 충분히 산화시켜 원수 정화효과의 극대화를 기대할 수 있게 하는 물리적 처리단계, 또는 생물학적 처리단계, 또는 화학적 처리단계 등 이들이 복합적으로 조합된 염색폐수 처리방법과 그 장치를 제공하는 잇점이 있다.Dyeing wastewater treatment method and apparatus according to the present invention as described above to ensure the homogeneity of the raw water by extending the residence time of the raw water, to increase the dissolved oxygen amount by adding a high concentration of pure oxygen dissolved in the respiration of the microorganisms By ensuring a sufficient amount of oxygen, the physical treatment step or biological treatment step to maximize the growth of microorganisms, and to fully oxidize the hard-degradable contaminants contained in the raw water by the phentom oxidation method, which can be expected to maximize the raw water purification effect, Or there is an advantage to provide a dyeing wastewater treatment method and apparatus in which these are combined, such as chemical treatment step.
