Massive oily wastewater discharged from industrial production and human daily life have been an urgent envi-ronmental and ecological challenge. Superhydrophobic materials have attracted tremendous attention due to their unique properties and potential applications in the treatment of wastewater. In this study, a novel superhydrophobic/superoleophilic composite melamine sponge modified with dual silanized SiO2 microspheres was fabricated simply by a two-step sol–gel method using vinyltriethoxysilane and hexadecyltrimethoxysilane as functional agent, which exhibited a water contact angle of 153.2° and a water sliding contact angle of 4.8°. Fur-thermore, the composite sponge showed the excellent oil adsorption performance and the compressive elasticity reaching up to 130 g·g?1 of dichloromethane and 33.1 kPa of compressive stress. It was worth noting that the composite sponge presented the excellent separation efficiency (up to 99.5％) in the processes of continuous oil/water separation. The robust superhydrophobic composite melamine sponge provided the possibility with the practical application for oil–water separation.

制图系统是现代管道测量的重要辅助系统,但传统的制图系统中绘图软件和数据处理软件是分开的,降低了制图系统的工作效率。因此提出基于ArcGIS的地下金属管道纵横断面制图系统设计与实现课题。首先进行基于ArcGIS的制图系统的系统硬件设计,然后进行基于ArcGIS的制图系统软件设计,软件设计包括图片管理模块设计,绘图图层处理模块设计和编辑与显示模块。最后设计测试实验证明该系统比传统方法的数据处理效率更高
介绍一种处理氨碱废渣液的新型工艺。本工艺是对制盐、制碱两大系统的资源进行整合、利用。利用来自制盐系统的制盐冷凝水对氨碱废渣液进行第一次清洗,清洗出的母液可直接去矿山采卤;用工业水对废渣液进行二段、三段清洗,出来的清液回纯碱石灰车间进行化灰;清洗得到的固体砂粒可作为建筑用材料。此工艺对两大系统的废弃资源进行整合利用,特别是对氨碱废液进行分级处理,变废为宝,即减轻了企业的环保压力,又使氨碱废液得到了资源化利用,增加了企业的收益。
