济南市水文地质特征对地下水污染的影响分析

从环境水文地质学的角度出发，对济南市地下水污染的主要途径和方式，以及局部地下水重污染区进行了较为详细的分析，济南市地下水污染以浅层地下水污染为主，局部地区深层地下水也已受到污染，并有进一步加重的趋势，地下水严重超采，造成多处地表塌陷和降落漏斗，并成为济南市地下水的重污染区。     

试论我国陆地再生能源资源及其特征

在世界矿物能源资源日趋减少的今天,再生能源资源引起人们广泛的兴趣,特别是陆地再生能源资源更是如此。本文对我国陆地再生能源资源——太阳能、风能、水能、生物质能——中的前两种能源资源进行了分区及分省计算,并依据全国已有的调查及普查资料,对后两种源能资源进行了分省及分区统计,在此基础上又对全国陆地再生能源资源的数量、分布及特征进行了对比分析,并从宏观上提出了开发利用我国陆地再生能源资源的建议和设想。     

大气中苯乙烯的气相色谱法测定

采用活性炭管吸附大气中基苯乙烯，以二硫化碳洗脱，以溴水加成后，用气相色谱电子捕获器测定苯乙烯的二溴加成物。本方法适合于检测多种污染物共存的大气中痕量苯乙烯。其线性范围为０．０１５－０．７４ｎｇ，最低检出浓度为０．００１ｍｇ／ｍ＾３；重现性实验的变异系数为２．３％：当活性炭管吸附苯乙烯在２．９μｇ时，回收率为９０％，吸附苯乙烯０．２９μｇ时，回收率为７２％。     

Preconcentration and determination of trace copper(II) in natural water using silica gel modified with 1-(2-pyridylazo)-2-naphthol

Trace copper (II) in water can be preconcentrated using silica gel modified with 1-(2-pyridylazo)-2-naphthol (PAN) and be determined spectrophotometri-cally. The conditions for the preconcentration were studied. The method was applied to both artificial and natural water samples and the results suggest that copper (II) of ppb level in water can be measured accurately after the preconcentration.

高硫原油加工过程硫回收水平分析

分析了金陵分公司最近三年来加工高硫原油带入的硫在全厂炼油过程的分布情况。随着原油加工量及含硫量的快速增长，硫回收能力凸现不足，表明目前正在加速建设的加氢精制和硫磺回收装置是十分必要的，这将进一步提高综合硫回收水平。从长远来看，还需采用扩大加氢工艺能力，在提升产品质量的同时达到减少硫向环境排放的目的。     

抚仙湖面源污染特征及其防治对策

根据抚仙湖径流区污染物负荷量的调查结果,抚仙湖水污染特征以面源为主,面源入湖水量占98%,TP占81.4%,TN占85.9%,因此控制面源是保护抚仙湖的关键。提出了防治抚仙湖面源污染的生态治理及工程治理对策。     

In situ preparation of g-C3N4/Bi4O5I2 complex and its elevated photoactivity in Methyl Orange degradation under visible light

A graphite carbon nitride(g-C_3N_4) modified Bi_4O_5I_2 composite was successfully prepared insitu via the thermal treatment of a g-C_3N_4/Bi OI precursor at 400°C for 3 hr.The as-prepared g-C_3N_4/Bi_4O_5I_2 showed high photocatalytic performance in Methyl Orange(MO) degradation under visible light.The best sample presented a degradation rate of 0.164 min~(-1),which is 3.2 and 82 times as high as that of Bi_4O_5I_2 and g-C_3N_4,respectively.The g-C_3N_4/Bi_4O_5I_2 was characterized by X-ray powder diffractometer(XRD),scanning electron microscopy(SEM),transmission electron microscopy(TEM),Raman,X-ray photoelectron spectroscopy(XPS),ultraviolet-visible diffuse reflectance spectra(DRS),electrochemical impedance spectroscopy(EIS) and transient photocurrent response in order to explain the enhanced photoactivity.Results indicated that the decoration with a small amount of g-C_3N_4 influenced the specific surface area only slightly.Nevertheless,the capability for absorbing visible light was improved measurably,which was beneficial to the MO degradation.On top of that,a strong interaction between g-C_3N_4 and Bi_4O_5I_2 was detected.This interplay promoted the formation of a favorable heterojunction structure and thereby enhanced the charge separation.Thus,the g-C_3N_4/Bi_4O_5I_2 composite presented greater charge separation efficiency and much better photocatalytic performance than Bi_4O_5I_2.Additionally,g-C_3N_4/Bi_4O_5I_2 also presented high stability.·O_2~-and holes were verified to be the main reactive species.     

城市生活垃圾综合处理系统的选择

以上海城市生活垃圾处置为对象，利用层次分析方法，选择了分选回收＋堆肥＋卫生填埋的综合处置系统，并且确定了堆肥方式应首先考虑仓式静态好氧堆肥。经过运行费比较，所选择的综合处置系统比现行的处置系统具有明显的优势。
