Description
본 발명은 폐수처리용 COD제거 조성물에 관한 것으로 특히, 화학적으로 결합된 조성물로 오염물질 즉, COD를 분리 제거시키도록 처리하는 발생기 산소를 포함한 폐수처리용 COD제거 조성물에 관한 것이다.The present invention relates to a COD removal composition for wastewater treatment, and more particularly, to a COD removal composition for wastewater treatment, including generator oxygen, which is treated to separate and remove contaminants, that is, COD, with a chemically bonded composition.
산업폐수나 생활용 하수로 인한 환경오염 문제가 나날히 심각하게 야기됨에 따라 식수로 사용하고 있는 상수도의 오염이 극심하게 나타나고 있다.Due to the serious problem of environmental pollution caused by industrial wastewater and domestic sewage, the pollution of the water supply used as drinking water is extremely severe.
이러한 오염원인중의 하나인 COD(화학적산소 요규량) 유발물질로 인하여 우리국민의 환경 및 보건이 위험수위에 올라있는 것을 잘 알려진 사실이다.It is a well-known fact that one of the causes of pollution, the COD (chemical oxygen demand) inducing the danger and environmental health of our people.
이러한 오염물질을 처리하기 위한 방법으로는 물리적 처리방법, 화학적 처리방법, 생물학적 처리방법등으로 크게 나누어진다.Methods for treating such pollutants are classified into physical treatment, chemical treatment, and biological treatment.
본 발명은 상술한 방법중의 하나인 화학적 처리방법에 의하여 산업폐수에 함유된 COD를 충분히 제거하여 처리하는 방법이며 발생기 산소를 포함한 폐수처리용 COD제거 조성물을 제조하기 위한 방법에 관한 것이다.The present invention relates to a method for sufficiently removing and treating COD contained in industrial wastewater by a chemical treatment method, which is one of the above-described methods, and relates to a method for producing a COD removal composition for wastewater treatment including generator oxygen.
오염된 폐수가 공기에 의하여 자연적으로 처리되는 자정작용이 공기중인 산소에 의하여 처리되는 방법인 점에 착안하여 이러한 자정작용의 원리를 인위적으로 재현할 수 있는 조성물을 창안함으로써 수질을 오염시키고 있는 물질인 COD를 제거하는 것이다.Focusing on the fact that the self-cleaning action of contaminated wastewater is treated by air in the air is a method of treating the water quality by creating a composition that can artificially reproduce the principle of the self-cleaning action, To remove the COD.
종래의 산소, 발생기 산소를 이용한 오염물질 처리방법으로는,In the conventional method of treating pollutants using oxygen and generator oxygen,
(1) 오존 발생기 이용방법.(1) How to use ozone generator.
(2) 순 산소 폭기방법.(2) Pure oxygen aeration method.
(3) 에레터(Aeretor)를 이용한 방법등이 있으나 오존 발생기 이용방법은 설치비, 동력비가 고가이며 순 산소 폭기방법은 폐수관리가 용이하지 않으며, 에테터를 이용한 방법은 설치비, 동력비, 유지관리비가 고가이기 때문에 이러한 문제점을 해결하기 위하여 본 발명이 조성물을 연구, 개발하기에 이르렀다.(3) There are methods using an aeretor, but the method of using an ozone generator is expensive to install and power, and the method of net oxygen aeration is not easy to manage wastewater. In order to solve these problems, the present invention has led to the research and development of the composition.
또한 종래의 폐수처리방법은 폐수의 중화재, 무기응집재, 응집보조제등 여러 가지 약품을 혼성사용함으로써 COD를 제거하여 정화하는 원리로, 다량의 약품투입으로 인하여 미반응되는 약품의 손실 및 약품의 적재장소로 인한 부지, 약품의 과다투입에 의한 독성물질 유발등 여러 가지 곤란한점들이 많아 폐수처리를 제대로 할 수 없는 폐단이 있었던 것이다.In addition, the conventional wastewater treatment method uses a mixture of various chemicals such as neutralizer, inorganic coagulant, and coagulant aid of the wastewater to remove and purify the COD. Lots of difficulties, such as the site caused by the place of loading and the toxic substances caused by the over-injection of the chemicals, were so many that the wastewater could not be properly treated.
본 발명은 상기와 같은 폐단을 해결하고자 창출한 것으로, COD제거 조성물의 비율은 H2O를 1로 기준하여 발생기 산소를 포함한 30% 용액의 과산화수소에 메타규산나트륨과 응집보조제인 유기고분자 응집제를 각각 4 : 0.001 : 0.025의 비율로 혼합하여 이루어진 조성물에 첨가물인 구연산칼슘 및 염화칼슘을 각각 0.001 : 0.001의 비율로 다시 혼합하여서 액상의 조성물로 이루어진 것으로 그 성상은 무상의 액체를 띄고 있으며 PH는 4.2 : 4.5, 비중은 1.10 : 1.15 또 점도는 1.10 : 1.20를 갖고 있게 된다.The present invention was created in order to solve the above-mentioned end, the ratio of the COD removal composition is based on H 2 O 1 and the organic polymer coagulant which is sodium metasilicate and coagulant in 30% solution containing generator oxygen, respectively. 4: 0.001: 0.025 in the composition consisting of a mixture of additives calcium citrate and calcium chloride in a ratio of 0.001: 0.001, respectively, was mixed again to form a liquid composition with the appearance of a liquid free PH of 4.2: 4.5 It has a specific gravity of 1.10: 1.15 and a viscosity of 1.10: 1.20.
이와 같은 본 발명의 조성물의 제조방법을 더욱 상세히 설명하면When explaining the production method of such a composition of the present invention in more detail
1) 과산화수소(30%)의 용액 800g을 물 200ml에 교반용해시키고, 메타규산나트륨 2g을 투입한 유기고분자 응집제 5cc를 투입시킨다. 이때 유기고분자 응집제는 순간적인 발생속도가 빠른 과산화수소를 억제하기 위한 것이다.1) Dissolve 800 g of a solution of hydrogen peroxide (30%) in 200 ml of water, and add 5 cc of organic polymer flocculant with 2 g of sodium metasilicate. At this time, the organic polymer flocculant is for suppressing the hydrogen peroxide that is instantaneously occurring.
2) 구연산칼슘 및 염화칼슘 0.1% 혼합한 수용액을 만든다.2) Make an aqueous solution mixed with calcium citrate and calcium chloride 0.1%.
즉, 상기 용액은 첨가물로써 침강성을 증가시키기 위함이다.That is, the solution is to increase the settling property as an additive.
3) 1)공정과 2)공정의 조성물을 다시 혼합시켜서 수용액을 만들어 포장 및 제품화한다.3) Mix the composition of 1) process and 2) process again to make an aqueous solution, then package and product.
상기와 같이 이루어진 본 발명이 COD제거 조성물을 폐수가 모이는 집수조에 투입하여 PH 3 : 4, PH 11 : 12에서 30 : 60분 정도 체류시간이 지나면 COD는 제거가 되고 이때 무기응집체의 소량 투입(10ppm)으로 응집침전, 또는 부상분리시키는 방법에 의해 악성폐수, 산알카리폐수, 난분해성 폐수에서 효과적으로 COD를 제거할 수 있는 것이다.The present invention made as described above is a COD removal composition is put into the sump collecting the waste water, PH 3: 4, PH 11: 12 to 30: 60 minutes after the residence time is COD is removed and at this time a small amount of inorganic aggregates (10ppm ), COD can be effectively removed from malignant wastewater, acid alkali wastewater, and hardly degradable wastewater by flocculation sedimentation or flotation.
이러한 본 발명이 COD제거 조성물의 적용범위는 다음과 같다.The scope of the present invention COD removal composition is as follows.
PH3~4→ 50ppm투입=중화조=반응조=침전조PH3 ~ 4 → 50ppm injection = neutralization tank = reaction tank = sedimentation tank
PH11~12→50ppm투입=중화조=반응조=침전조PH11 ~ 12 → 50ppm input = neutralization tank = reaction tank = sedimentation tank
이때 본 발명의 조성물에서 COD를 제거시키는 물질은 과산화수소이며 메타규산나트륨 및 유기고분자 응집제는 과산화수소에 의해 발생한 슬럿지의 침강성 증대시키기위한 물질로 사용되며 또한 유기고분자 응집제는 과산화수소와 물과 반응시 발생되는 산화성물질을 최소한으로 기체화하는 것을 막기위한 것이다. 또 구연산칼슘은 FLOC침강제이며 염화칼슘은 흡착의 효과가 있으므로 COD조성물에서 생긴 FLDC의 고액분리를 주목적으로 한 것이다.At this time, the material to remove COD in the composition of the present invention is hydrogen peroxide, sodium metasilicate and organic polymer flocculant is used as a substance to increase the sedimentation of the sludge caused by hydrogen peroxide, and the organic polymer flocculant is an oxidative property generated when reacting with hydrogen peroxide and water It is intended to prevent the gasification of substances to a minimum. In addition, calcium citrate is a FLOC precipitater and calcium chloride has the effect of adsorption, so the main purpose is the solid-liquid separation of FLDC from COD composition.

이와 같이 각종 산업폐수에 본 발명의 조성물을 투입하게 될 때 제 1)공정에서 제조된 혼합물은 매 적용범위가 산도, 알카리도에 구애받지 않으므로 적응력이 우수할 뿐만아니라 COD를 제거침전시켜 COD가 함유된 폐수를 효과적으로 분해시킬 수 있으며, 또 제 2)공정에서 제조된 조성물은 침전된 물질을 흡착시켜 재 침전시킴으로써 물리적, 화학적, 생물학적 처리를 종합적으로 하는 난분해성 폐수처리시 폭기조에서 생성되는 미생물 오니(Flock)의 벌킹라이징(Bulking rising) 현상도 부가적으로 억제할 수 있게 된다.As such, when the composition of the present invention is added to various industrial wastewaters, the mixture prepared in step 1) is excellent in adaptability because the application range is not limited to acidity and alkalinity, and also COD is eliminated by precipitating COD. The composition prepared in step 2) can effectively decompose wastewater, and microorganism sludge produced in the aeration tank during the difficult-decomposable wastewater treatment in which physical, chemical and biological treatments are combined by adsorbing and reprecipitating the precipitated material. In addition, the bulking rising phenomenon of) can be further suppressed.
부가적인 현상은 이는 이미 알려진 바와 같이 과산화구소, 염소, 오존등으로 살균하여 벌킹라이징현상을 제거할 수 있는 것으로 본 발명의 조성물에 포함된 과산화수소에 의해서 제거가 되는 것으로 본 발명에서는 그리 중요한 것은 아니다. 다만, 폐수에 함유된 COD를 분리제거하는 것이 주된 목적이다.An additional phenomenon is that it is possible to remove the bulking phenomena by sterilizing with a peroxide, chlorine, ozone, etc., as already known, which is removed by hydrogen peroxide included in the composition of the present invention, which is not so important in the present invention. However, the main purpose is to separate and remove the COD contained in the wastewater.
또한 제3)공정에서 제조된 본 발명의 발생기 산소를 포함한 폐수처리용 COD제거 조성물은 COD가 함유된 폐수에 사용할 수 있는 것으로 일반사용되는 중화제(황산, 가성소다)의 양을 최대한 줄일 수 있어 산업발전에 획기적인 발전을 도모하여 국가환경 보전의 일환으로 기대될 수 있는 것이다.In addition, the COD removal composition for wastewater treatment containing the generator oxygen of the present invention manufactured in the third process can be used for the wastewater containing COD, which can reduce the amount of neutralizing agents (sulfuric acid and caustic soda) commonly used in the industry. It can be expected as a part of national environmental preservation by promoting breakthrough development.
