Abstract
본 발명은 게나 새우껍질등에서 추출된 키틴으로부터 탈아세틸화하여 만들어진 키토산을 응집제 용액으로 조제하여 도금폐수내의 중금속흡착이나 식품폐수, 축산폐수, 피혁폐수내의 부유물들을 응집시켜 제거함으로써 폐수 처리제로 사용하는 방법에 관한 것으로, 그 폐수 정제효과가 탁월한 외에 키토산자체가 2차 공해가 없는 무독, 무해의 천연고분자이기 때문에 슬럿지중 유효자원 회수와 재활용이 가능할 뿐만 아니라 탈수 효율이 높아 슬럿지 처리에 경제적인 이점이 크다.In the present invention, chitosan prepared by deacetylation from chitin extracted from crab or shrimp shell is prepared as a coagulant solution, and the heavy metal adsorption in plated wastewater or flocculation and removal of suspended solids in food wastewater, livestock wastewater, and leather wastewater is used as a wastewater treatment agent. In addition, the wastewater refining effect is excellent, and chitosan itself is a non-toxic and harmless natural polymer without secondary pollution, so it is not only possible to recover and recycle active resources in the sludge, but also has high economical efficiency in sludge treatment due to its high dehydration efficiency. .
Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.
제10도는 키토산 주입농도 110ppm에서 변화에 따른 피혁폐수의 투과율 변화도.10 is a change in the permeability of leather wastewater according to the change in the chitosan injection concentration of 110ppm.
제11도는 PH6.7에서 키토산 주입농도별 피혁폐수의COD제거율 변화도.11 is a change in the COD removal rate of leather wastewater by chitosan injection concentration at PH6.7.
제12도는 PH6.7에서 키토산 주입농도별 피혁폐수의 SS제거율 변화도.12 is a change in SS removal rate of leather wastewater by chitosan injection concentration at PH6.7.
제13도는 피혁폐수에서 키토산과 폴리아크릴아마이드 중금속 제거율 비교도.Figure 13 is a comparison of chitosan and polyacrylamide heavy metal removal rate in leather wastewater.
