Environmental cleansing insect which is well known for Black Soldier Fly(BSF), Hermetia illucens egg mass wightby hatch survival rate and animal carcass and pig feces decomposition ability trial and examined survival rate. BSF eggmass examined A-1,2,3 group each 4.56g equivalent condition hatch after survival rate, Survival BSF larva was36,394.67±3,038.863, survival rate average was 64.8%. Put the BSF larva 45,000 into the Python regius carcass showeddecomposition takes 9 days, wight was decreased rate to 67%. Put A-1,2,3 survival BSF larva dived half into pig feces,carcass. Pig carcass, feces each 6.35kg decomposition take 12 days, 14 days, wight decreased rate to 58.8%, 63.2%, Survivalrate showed to 4.87%, 85.6%, one larva per 1.16g, 2.26g pig carcass, feces take decomposition. Since the lack of food,BSF larva didn’t grow more than the pig carcass feed group, extra in 6kg of pig feces feed. Amount pig feces take12.35kg decomposition during 32 days. Manure make 4.2kg.

많은 계산량이 요구되는 삼차원 접촉 문제의 효율적인 유한요소 해석을 위하여 영역/경계 분할 기법을 적용하였다. 접촉 경계면의 부등식 적합 조건과 부영역, 공유면, 접촉 공유면의 등식 적합 조건을 모두 벌칙 함수로 처리하였다. 이에 따라 모든 유효 강성 행렬이 양 정치화되므로, 역행렬과 같은 각종 행렬 연산이 매우 간편해진다. 또한 전체 영역의 형상이 복잡하더라도, 임의의 부영역, 공유면, 접촉 공유면 단위로 쉽게 유한요소 모델링할 수 있다. 즉, 관련 지배 방정식은 물론 경계 조건도 독립적으로 이산화할 수 있으므로, 국부적인 비선형 접촉 조건에 대한 효율적인 해석이 가능하다. 간단한 수치 예제를 통하여 삼차원 접촉 해석의 효율성에 관한 기본적인 경향을 검토하였다.

To date, carbon and nitrogen co-doped photocatalysts (CN-TiO2) for environmental application focused mainly on the aqueous phase to investigate the decomposition of water pollutants. Accordingly, the present study explored the photocatalytic performance of CN-TiO2 photocatalysts for the purification of indoor-level gas-phase aromatic species under different operational conditions. The characteristics of prepared photocatalysts were investigated using X-ray diffraction, scanning emission microscope, diffuse reflectance UV-VIS-NIR analysis, and Fourier transform infrared (FTIR) analysis. In most cases, the decomposition efficiency for the target compounds exhibited a decreasing trend as input concentration (IC) increased. Specifically, the average decomposition efficiencies for benzene, toluene, ethyl benzene, and xylene (BTEX) over a 3-h process decreased from 29% to close to zero, 80 to 5%, 95 to 19%, and 99 to 32%, respectively, as the IC increased from 0.1 to 2.0 ppm. The decomposition efficiencies obtained from the CN-TiO2 photocatalytic system were higher than those of the TiO2 system. As relative humidity (RH) increased from 20 to 95%, the decomposition efficiencies for BTEX decreased from 39 to 5%, 97 to 59%, 100 to 87%, and 100 to 92%, respectively. In addition, as the stream flow rates (SFRs) decreased from 3.0 to 1.0 L min-1, the average efficiencies for BTEX increased from 0 to 58%, 63 to 100%, 69 to 100%, and 68 to 100%, respectively. Taken together, these findings suggest that three (IC, RH, and SFR) should be considered for better BTEX decomposition efficiencies when applying CN-TiO2 photocatalytic technology to purification of indoor air BTEX.
