农村污水治理存在地形复杂,污水收集难且污染源分散;排水管道建设不完善,运行难且建设成本高;监测与修复精准度不够;对污染物无法高效处理,排放标准不达标等痛点。以纳米材料为核心的纳米技术以不同物理和化学性质,在不同的外部激励条件下可以建立起极大的梯度场并形成自驱动,这一特性为特定的水污染问题提供监测-修复一体化解决方案;通过建立纳米科技——生态景观长效协同机制,对污水进行二次深度处理,促进良性生态演替,建立平衡的生态系统,实现区域生态全面提档升级,实现水环境长效保持。

We report the finding of the Wolitu Pb-Zn deposit in Inner Mongolia, China, through a series of geochemical surveys. The Wolitu area, located in the loess-cover area in the Hure Banner, Tongliao City,Inner Mongolia, and neighboring the Horqin Sandy Land to the north, had no previous history of Pb-Zn mining or record of Pb-Zn mineralization. Our study identified a large Pb-Zn anomaly with potential zones of mineralization by stream sediment survey. Random rock sampling reveals limonitization at sporadic outcrops in the gullies. The high concentrations of Pb in the residual debris provided guidelines to fix the position for exploratory trench. Oxidized concealed orebodies were identified by *** orebodies in veins hosted within the structural zone between slates and marbles of the upper Carboniferous Shizuizi Formation and the Permian granite were discovered by drilling. It is computed that the ore reserve may reach up to 540,000 tones with Pb grade of 1.27% and Zn of 1.9%. This case study is an excellent example for identifying potential polymetallic deposits in loess covered terrains using geochemical exploration.

Rapid weight gain(RWG) in infants is associated with numerous health problems, and its risk factors are still unclear. We assessed 98,097 maternal-infant pairs from a population-based cohort study and followed up with them until the infants were6 months old. We assessed the associations between maternal prepregnancy weight status;gestational weight gain;feeding pattern;and infants’ RWG at 0–1, 0–3, 1–3, and 3–6 months using multivariate unconditional logistic regression models, with controlled confounders. We found that maternal prepregnancy weight status, gestational weight gain, and feeding pattern at the1 st, 3 rd, and 6 th months had significant impacts on the infants’ RWG at each time period(P<0.05). Infants with overweight/obese mothers had a higher risk of RWG after birth, whereas those of mothers who experienced excessive gestational weight gain had higher risks of RWG from birth than the other groups(P<0.01). Infants who were formula-fed had a higher risk of RWG than breastfed infants at the same time point(P<0.01). In conclusion, maternal prepregnancy obesity, excessive gestational weight gain, and formula-feeding were risk factors for infants’ RWG during the first 6 months of life.

An existence theorem of homoclinic orbit is given for second order Hamiltoniansystem-x(t) + a(t)x(t) - Wx(t, x(t)) = x(t)when = 1, where 1 is the first eigenvalue of operator Lx = x - a(t)x, and Wx(t, x) issublinear growth in x Rn. When Wx(t, x) is odd in x,. infinitely many distinct pairs ofhomoclinic orbits are obtained and the bifurcations occur for each 1.

为了解成都市江安河丰水期及枯水期水体中浮游植物的群落结构特征,于2021年9月1日和12月25日,对江安河中的浮游植物种类进行了调查研究,对比了丰、枯水期的浮游植物群落结构,利用多样性指数(H′)、均匀度指数(J)和丰富度指数(D)的变异特征,对江安河中的浮游植物开展了群落结构多样性分析。调查显示:江安河丰、枯水期的浮游植物类型均以硅藻居多,绿藻门和蓝藻门类最少;浮游植物密度依次为0.16×10^(6)~0.25×10^(6) cells/L、0.24×10^(6)~30.5×10^(6) cells/L;丰水期,各点位的浮游植物密度和浮游植物生物量含量差别并不明显,而在枯水期,各点位的浮游植物密度和浮游植物生物量含量差别显著。这项研究有助于对城市河流的水生态环境进行有效的管理,同时为城市河流的水生态环境保护提供一定的参考依据。
