  • 유기농액비 자가제조 방법의 표준화를 위해 농가 현황조사를 통해 유기농액비 제조방법을 분류하고 제조 시기별 성분함량 변동상을 분석하였다. 조사대상 액비는 경기 9, 강원 5, 충북, 1, 충남 20, 전남 6, 경북 5, 경남 8 등 총 54종이었다. 자가제조 유기농액비에 사용된 재료는 감, 매실, 복숭아, 사과, 참다래, 토마토, 파프리카, 양파, 파, 인삼, 미나리, 민들레, 쇠비름, 쑥, 익모초, 산야초, 황기, 환삼덩굴, 으름열매, 은행과피, 배 어린 열매, 감껍질, 깻묵, 들깨대, 물미역, 쌀뜨물, 쌀겨, 꽁치, 바다생선 (잡어), 불가사리, 생선부산물(내장, 뼈 등), 액젓부산물(해산물의 뼈가 많이 함유된 물질), 동물뼈(돼지, 닭 등), 골분, 혈분, 천매암, 천일염, 계란껍질, 조개껍질, 게껍질, 새우껍질, 굴껍질, 농가부산물, 음식부산물, 구아노, 들깨 대 숯, 참깨 대 숯 등이었다. 제조방법은 기본재료+물, 기본재료+물+미생물, 기본재료+당밀, 기본재료+당밀+미생물, 기본재료+흑설탕, 기본재료+흑설탕+미생물 등이었다. 유기농액비의 화학적 특성은 다양하였으며, 혈분을 주 원료로 한 유기농액비의 화학성변화는 시간의 경과함에 따라 pH는 4.99에서 3.85로 낮아졌지만, EC, T-C, T-N, $P_2O_5$, $K_2O$, CaO, MgO, $Na_2O$, Fe, Mn, Zn 등은 높아졌다.

  • After feeding mixed samples, VS ranged from 60 to 80% of total costs in 15 days. EC ranged from1.21 to 2.45, 1.25 to 2.1 and 1.2 to 1.88mS/cm when worms were fed with a mixture of by-products of tidal current and sewage sludge, a mixture of by-products of algae producy, and food wastes and a mixture of by-products of algae producy, sewage sludge and food wastes. That means the kinds of mixture don't have any negative impacts on worms survival. With the feed with a mixture of by-products of algae producy and food wastes and a mixture of by-products of algae producy, sewage sludge and food wastes, pH shows stable 5.4 to 6.7, and 6.2 to 7.4 where is suitable for worms. But a mixture of by-products of algae producy and sewage sludge is out of proper scope for raising worms, in other words, extra care will be necessary. In case of Eh, a mixture of by-products of algae producy and sewage sludge make eh negative (-) in early stage so also when feeding worms, also extra care will be needed. NaCl ranged from 0.32 to 0.82% or form 0.23 to 0.61% when a mixture of by-products of algae producy and food wastes and a mixture of by-products of algae producy, sewage sludge and food wastes were fed. So taking care of salts will be essential whenever feeding.

  • UV-induced transformations in the characteristics of dissolved organic matter (DOM) and the subsequent effects on the disinfection by-product formation potential (DBPFP) were investigated using the mixtures of the two humic substances with different sources, and two different size fractions of Suwannee River fulvic acid (SRFA). 7 day-photodegradation resulted in the decrease of specific ultraviolet absorbance (SUVA) of the mixtures as well as the specific DBPFP. After the irradiation, however, higher specific DBPFP values were consistently observed at the same range of the SUVA values. This suggests that non UV-absorbing components, generated by the UV-irradiation, may contribute to the formation of DBPs. Two different molecular size fractions of SRFA showed dissimilar responses to photodegradation. The behavior was also influenced by the types of the DBPs generated. Higher levels of trihalomethenes (THMs) were formed per organic carbon for the high molecular fraction compared to the low molecular fraction, whereas no differences were found in the formation of haloacetic acids (HAAs) between the two different size fractions. The formation of the two types of DBPs also differed by the irradiation times. Specific formation potential of THMs consistently increased upon the irradiation, whereas HAAs showed the initial increase followed by the decrease in their specific formation potential.
