Reliable uncertainty estimates can also be used to increase the quality of emission inventories. This paper took the emission of CH4 from the solid waste landfill in Hefei City in 2014 as an example, and employed the mass balance method to compute its emission. Monte Carlo method was used to carry out the sensitivity analysis and compute uncertainty. Through computing, 95% confidence interval of CH4 emission from landfill in Hefei City was (1.89~3.40) × 104 t. The mean value was 2.61 × 104 t with uncertainty range of –27.59%~30.27%. Among all the parameters, the decomposable proportion of DOC (DOCf ) showed the greatest impact on the emission of CH4 from the landfill and its contribution to emission result was 26.33%. Followed by the degradable organic carbon (DOC) was 26.29%, the amount of solid waste (MSW) was 13.63%, methane correction factor (MCF) was 6.93% and the proportion of methane in landfill gas (F) was 6.58%. The results showed that compared with traditional error propagation method, it improved the accuracy and quality of assessment and provided a scientific basis to improve the quality of inventory as well.","PeriodicalId":17101,"journal":{"name":"Journal of Residuals Science & Technology","volume":"15 1","pages":"51-57"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78285951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a high ethanol yield crop, sugarcane has attracted increasing industrial interest as a raw material for biofuel and the risk of heavy metal in it is negligible if the sugar produced is to be fermented into ethanol rather than by consumed. This study is to do a preliminary investigation if sugarcane is a suitable crop for phytoremediation in heavy metal polluted farmland in a context of geographic conditions in southern China, thirty-eight soil and sugarcane samples were collected in five villages in a typical agricultural county called Huangjiang which is located in the Huanjiang River Basin in Guangxi province. Sugarcane is widely cultivated in Huangjiang as one of the major economic crops, meanwhile, pollutions induced by mining and ore-extraction in this area has resulted in heavy metals entering the farmland soils. Samples collected were used to assess the correlation of the level of heavy metals in the soil, and their concentrations in roots, sections of stems and leaves. Seven heavy metals were selected in this study and the results showed that most of the toxic heavy metals intake by sugarcane accumulated in the roots, while only a small portion is transferred to the stems and leaves. The study initially outlined sugarcane as a potential candidate for phytoremediation in farmland polluted by heavy metals with economic motivate in this subtropical geographical background.","PeriodicalId":17101,"journal":{"name":"Journal of Residuals Science & Technology","volume":"50 1","pages":"143-154"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77850799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is important to stabilize wastewater sludge before its application to agricultural land. Constructed wetlands (CWs) have been widely applied for stabilization of sludge. In CWs, plants, especially reeds, promote degradation of pollutants in the rhizosphere and are the principal mechanisms for PAH-contaminated sludge phytoremediation. We studied PAH removal in sludge planted with Phragmites australis (common reeds) in onsite experiments over a 3-year period comprising 2 years of sludge application and 1 year of resting. The average PAH content in the feeder sludge was 5.7 mg kg–1 (DW), consisting of approximately 48% low-molecular-weight (2–3 ring) PAHs, 27% middle-molecular-weight (4 ring) PAHs and 25% high-molecular-weight (5–6 ring) PAHs. After 3 years, the average PAH content in stabilized sludge was 2.1 mg kg–1 (DW), which was lower than that of the feeder sludge. Overall, about 66% of low-molecular-weight PAHs (dominant type), 57% of middle-molecular-weight PAHs and 32% of high-molecular-weight PAHs were removed from the stabilized sludge. Additionally, there were spatial variations in PAHs in stabilized sludge, with PAHs being highest in the surface layer (12–14 cm) sludge, lower in the middle layer (6–8 cm) and lowest in the bottom layer (0–2 cm).","PeriodicalId":17101,"journal":{"name":"Journal of Residuals Science & Technology","volume":"1 1","pages":"107-114"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78805715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
