1Discharge inventory of pharmaceuticals and personal care products in Beijing,China显示文摘Pharmaceuticals and personal care products(PPCPs)are emerging environmental contaminants,whose potential risk for the ecological environment has caused wide attention in recent years.In China,quite a large amount of PPCPs were annually emitted into the environment.Their existence in different matrix has been reported frequently,including river water,sediment and soil.However,the contribution from different sources was seldom reported and still unclear in China.Wastewater treatment plant(WWTP)was usually considered to be the main source to the urban river,but livestock and aquaculture farms were also reported as significant pollution sources of PPCPs due to poor environmental management in China.This study summarized environmental discharges of different PPCPs from various sources and obtained the discharge data through different environment media in Beijing,the statistical source of PPCPs was analyzed in detail.The sources comprised WWTPs,excess sludge,hospital wastewater,municipal untreated wastewater,aquaculture wastewater and landfill leachate.This article helps understand the general situation and the potential risk of PPCPs in Beijing.Zhixia Zhang Bin Wang Honglin Yuan Ruixue Ma Jun Huang Shubo Deng Yujue Wang Gang Yu 2016Emerging Contaminants2016,2,3:1

3Enhance hydrates formation with stainless steel fiber for high capacity methane storage显示文摘In order to realize efficient gas storage of hydrate,stainless steel fiber(SSF)was added to 0.03%(mass)sodium dodecyl sulfate(SDS)solution for gas storage experiment.SSF can not only improve the problem that hydration heat cannot be removed effectively in the hydration process,but also improve gas storage speed and gas storage by increasing hydrate nucleation sites.Under the experimental conditions(273.2 K,5-9 MPa),the peaks of temperature rise in SDS+SSF systems were found to become much smaller than those in SDS systems.The maximum gas storage rate and the maximum methane uptake of SSF+SDS system reached 9.89-24.90 cm^(3)·g^(-1)·min^(-1) and 178.65-200.89 cm^(3)·(g H_(2)O)-1,respectively.Compared with the surfactant SDS solution without SSF,they increased by 10.47%-33.22%and 9.16%-25.36%,respectively.The effect of SSF length on gas storage performance was studied.Due to the continuous thermal conduction network,longer SSF showed a higher gas storage capacity and methane uptake rate compared with shorter SSF.At the same time,compared with other metal fillers,SSF+SDS not only had excellent gas storage performance,but also the amount of SSF(0.1 g·ml^(-1))was only 7.6%of foamed aluminum,and the volume gas storage density was increased by 145.4%.The use of stainless steel fiber made the best use of the thermal conductivity of metal,reduced the amount of metal used,and improved the volume density and mass density of gas storage.Zhixia Deng Shuanshi Fan Yanhong Wang Xuemei Lang Gang Li 2022Chinese Journal of Chemical Engineering2022,,10:0
