다음으로, 토양 오니 처리에 대한 결과를 설명하면, Next, explaining the results of the treatment of soil sludge,
유사의 토양 오니 배수 200 밀리리터 (이하, ㎖) 에, 본 발명의 응집제 (A), 본 발명의 응집제 (B), 그리고, 시판품을 사용하여 그 효과를 비교 검토하였다.The effect was compared and examined using the flocculant (A) of this invention, the flocculant (B) of this invention, and a commercial item in 200 milliliters (hereinafter, ml) of similar soil sludge drainage.
그 결과, 시판품에서는, 800㎎ 을 필요로 했지만, 본 발명의 응집제 (A) 에 서는 200㎎, 본 발명의 응집제 (B) 에서는 300㎎ 정도 투입하여 교반하면, 응집 침전이 발생하는데, 상청 수용액의 투과도는 본 발명의 응집제 (A) 쪽이 양호한 투과 결과가 얻어졌다. As a result, although 800 mg was required for a commercial item, in the flocculant (A) of this invention, about 200 mg and about 300 mg in the flocculant (B) of this invention were added and stirred, agglomeration precipitation generate | occur | produced, The permeability | permeability obtained the permeation | transmission result favorable for the coagulant (A) of this invention.
다음으로, 감자전분을 함유하는 배수 처리에 대한 결과를 설명하면, Next, the results of the drainage treatment containing potato starch,
유사 처리제인 본 발명의 응집제 (A) 의 효력 시험으로서, 감자전분 10g/l 및 20g/l 의 배수를 시작 (試作) 하여, 각각 200㎖ 에 대하여 본 발명의 응집제 (A) 200㎎ 및 300㎎ 을 첨가하여 응집 상태를 관찰하였다. As the potency test of the flocculant (A) of the present invention which is a similar treatment agent, drainage of 10 g / l and 20 g / l potato starch was started, and 200 mg and 300 mg of the flocculant (A) of the present invention were added to 200 ml, respectively. Was added to observe the aggregation state.
그 결과, 어느 조건 하에 있어서도 양호한 응집 침전이 확인되었다. As a result, good coagulation precipitation was confirmed under all conditions.
그래서, 본 발명의 응집제 (A) 의 능력 시험으로서, 감자전분 배수 10g/l 에 대한 첨가량을 구한 결과, 최소 첨가량으로서 40㎎ 인 것을 알 수 있었다. Therefore, as a capability test of the flocculant (A) of this invention, when the addition amount with respect to 10 g / l of potato starch drainage was calculated | required, it turned out that it is 40 mg as a minimum addition amount.
다음으로, 쌀 씻은 물 배수 처리에 대한 결과를 설명하면, Next, describing the results for the treatment of rice-washed water drainage,
쌀 4 합에 대하여 통상적인 씻기 방법을 행하여, 처음에는 두번째로 씻은 배수를 합친 것을 20O㎖ 사용하였다. A conventional washing method was performed for 4 rice mixtures, and 20OmL of the sum of the first washed drainage waters was used.
응집제로서는, 본 발명의 응집제 (A) 와 시판품을 첨가하여 그 효력을 비교하였다. As a flocculant, the flocculant (A) of this invention and a commercial item were added, and the effect was compared.

최종적으로는 500㎎ 이 필요하다고 생각된다. 또, 플록의 응집은 시간의 경과와 함께 상부에 집합되는 것이 관찰되었다. Finally, 500 mg is considered necessary. In addition, flocculation was observed to be gathered at the top with the passage of time.
한편, 시판품에서는 800㎎ 을 첨가해도, 전혀 응집은 발생되지 않고, 백색 현탁 상태이었다. On the other hand, even if it added 800 mg, in the commercial item, aggregation did not occur at all and was in a white suspended state.
또한, 우동의 뜨거운 국물 배수 처리에 대한 결과를 설명하면, In addition, the results of the hot broth drainage treatment of udon,
시판되는 우동 20 개를 3ℓ 의 뜨거운 물 (90℃ 이상) 중에서 푼 뜨거운 국물을 실험에 사용하였다. 뜨거운 국물을 8 배 희석, 4 배 희석 및 2 배 희석시킨 200㎖ 의 용액에 응집제로서, 본 발명의 응집제 (A) 를 사용하고, 8 배 희석에서는 135㎎, 4 배 희석에서는 195㎎, 2 배 희석에서는 350㎎ 을 첨가하였다. 발생된 플록은 전분을 응집하고 있기 때문에, 용액 중에 부유한 상태가 되어 응집되는 모습이 관찰되었다. The hot broth extracted from 3 commercially available udon noodles in 3 liter of hot water (90 degreeC or more) was used for the experiment. In a 200 ml solution in which hot broth was diluted 8-fold, 4-fold and 2-fold, the flocculant (A) of the present invention was used, and at 8-fold dilution, 135 mg, 1-95 mg, 2-fold In dilution 350 mg was added. Since the generated floc aggregated starch, the floc which became floating in the solution and was aggregated was observed.
그리고, 이 발명의 응집제 (A) 와 응집제 (B) 를 사용하여, 토양 오니, 감자전분, 우유를 각각 용해시킨 배수 및 쌀 씻은 물 등을 처리한 배수에 대한 pH 를, 하기의 표 1 에 나타낸다. And using the flocculant (A) and the flocculant (B) of this invention, the pH with respect to the wastewater which processed soil sludge, potato starch, the milk which melt | dissolved respectively, rice wash water, etc. is shown in Table 1 below. .
이 표 1 로부터도 알 수 있는 바와 같이, 이 발명의 응집제 (A), 응집제 (B) 모두, 중성영역에 있는 것으로, 바람직한 배수 기준을 클리어하고 있는 것을 알 수 있다. 따라서, 종래품의 응집제와 비교해도 손색이 없는 것이 판명되었다. As can be seen from Table 1, it can be seen that both the coagulant (A) and the coagulant (B) of the present invention are in the neutral region, thereby clearing a preferable drainage standard. Therefore, it turned out that there is no inferiority even compared with the conventional flocculant.
다음으로, 시판품의 우유의 배수 처리에 대한 결과를 설명하면, Next, when the result about the drainage treatment of the milk of a commercial item is demonstrated,
우유 10㎖ 에 20 배량 ∼ 100 배량의 물을 첨가하여 희석시킨 후, 이 발명의 응집제 (A) 140㎎ ∼ 660㎎ 을 첨가하여, 응집 상태를 관찰하였다. 그 결과, 양호한 우유 배수 처리 조건으로는, 30 배량 ∼ 70 배량의 물을 첨가하여 희석시킨 후, 이 발명의 응집제 (A) 240㎎ ∼ 600㎎ 을 첨가함으로써, 플록의 응집이 확인되었다. 그 중에서도, 가장 양호한 처리 조건으로서는, 50 배량의 물로 희석시켜, 응집제 (A) 240㎎ 을 첨가한 조건으로, 플록의 응집은 시간의 경과와 함께 진행되어, 용액 중에 부유한 후, 플록의 성장이 진행되어 침전되는 것이 관찰되었다. 〔표 2 참조〕After diluting by adding 20 times-100 times the amount of water to 10 ml of milk, 140 mg-660 mg of flocculants (A) of this invention were added, and the aggregation state was observed. As a result, as favorable milk drainage treatment conditions, floc flocculation was confirmed by adding 240 mg-600 mg of the flocculant (A) of this invention after adding and diluting 30 times-70 times of water. Among them, as the best treatment conditions, flocculation of flocs proceeds with the passage of time under the condition of dilution with 50 times the amount of water and the addition of 240 mg of the flocculant (A). Progression and precipitation were observed. [See Table 2]
이 표 2 로부터도 알 수 있는 바와 같이, 이 발명의 응집제 (A) 는, 어느 응집제를 첨가한 경우에도, 중성영역에 있는 것으로, 바람직한 배수 기준을 클리어하고 있는 것을 알 수 있다. 따라서, 종래품의 응집제와 비교해도 손색이 없는 것이 판명되었다. As can be seen from Table 2, even when any flocculant is added, the flocculant (A) of the present invention is in the neutral region, and it can be seen that the desired drainage standard is cleared. Therefore, it turned out that there is no inferiority even compared with the conventional flocculant.
