天祝县地震监测网点建设及地质构造断层划分的探讨

地震监测网点建设与地质构造断层划分是地震观测和预报技术的一个重要组成部分。必须按照中国地震局地震台网前兆标准和甘肃省地震局台网建设规定，统一布设网点，打破行政区域界线，根据地震活动背景，从地震活动性、灵敏性、密集性，重要性构造差异，人口密度等因素布局设立地震监测网点。地震监测网点布局必须服从地震科研和预报的需要，有目地、有组织、有限度、有预测。本文以天祝县地震监测网点建设为实例，探讨了以上问题。

废电池的环境污染及资源化价值分析

分析了各类废电池的资源化,安再生利用价值由高到低顺序依次为铅酸蓄电池、镍镉、镍氢电池、普通干电池。电池中含有的主要污染物质包括重金属以及酸、碱等电解质溶液。对环境和人体健康危害较大的废电池类别主要为：（1）含汞电池，指氧化汞电池，部分汞含量较高的锌锰和碱锰干电池；（2）铅酸蓄电池；（3）含镉电池，主要是Ni-Cd电池。废电池中化学物质释放进入环境过程是在电池包壳破损后发生的，或者是电池包壳本身发生浸蚀作用。普通家用干电池中的污染物质大多呈固态，由电池内部迁移到环境中是一种缓慢的过程。文中还分析了废电池污染环境的主要途径、采用各种不同处理、处置方式管理废电池可能引起的环境污染。     

Spatial Pattern Analysis of Regional Water Use Profile Based on the Gini Coefficient and Location Quotient

Water resources have become a barrier hampering socioeconomic development. Changes in the spatial distribution of water use profile have direct impacts to regional water use efficiency. However, the related research is inadequate, and a more suitable way to analyze regional water use profile is necessary. The Gini coefficient and location quotient, two reliable methods commonly used in discussing the spatial distribution of elements, were introduced and calculated. Taking Gansu Province as the study area, the concentration effect of industrial water use was the strongest, followed by domestic, environmental, and agricultural water use. However, a balanced distribution of agricultural water use failed to be coordinated with the production conditions, the center of Gansu’s grain production should be established to enhance the scale effect of agricultural production. The industrial agglomeration effect remained weak, and each region’s dominant industries need to be developed vigorously. Gansu’s domestic water use was consistent with its population distribution, but it is necessary to reduce the water use gap between urban and rural areas. With a growing awareness of environmental protection, environmental water use exhibited a more balanced distribution. Overall, the methods are simple and have good applicability, and the results can provide a reference in water use optimization.     

Catalytic ozonation treatment of papermaking wastewater by Ag-doped NiFe2O4: Performance and mechanism

The catalytic ozonation treatment of secondary biochemical effluent for papermaking wastewater by Ag-doped nickel ferrite was investigated. Ag-doped catalysts prepared by sol-gel method were characterized, illustrating that Ag entirely entered the crystalline of NiFe₂O₄ and changed the surface properties. The addition of catalyst enhanced the removal efficiency of chemical oxygen demand and total organic carbon. The results of gas chromatography-mass spectrometer, ultraviolet light absorbance at 254 nm and three-dimensional fluorescence excitation-emission matrix suggested that aromatic compounds were efficiently degraded and toxic substances, such as dibutyl phthalate. In addition, the radical scavenging experiments confirmed the hydroxyl radicals acted as the main reactive oxygen species and the surface properties of catalysts played an important role in the reaction. Overall, this work validated potential applications of Ag-doped NiFe₂O₄ catalyzed ozonation process of biologically recalcitrant wastewater.
