环境监测作为环境管理的重要手段之一,在经济发展过程中,我们应了解环境监测在经济建设中的地位和作用,充分有效的利用环境监测的成果,使之为经济发展服务。     

Decomplexation of Cu-1-hydroxyethylidene-1,1-diphosphonic acid by a three-dimensional electrolysis system with activated biochar as particle electrodes

The feasibility of decomplexation removal of typical contaminants in electroplating wastewater, complexed Cu(II) with 1-hydroxyethylidene-1,1-diphosphonic acid (Cu-HEDP), was first performed by a three-dimensional electric reactor with activated biochar as particle electrodes. For the case of 50 mg/L Cu-HEDP, Cu(II) removal (90.7%) and PO initial pH 7, acid-treated almond shell biochar (AASB) addition 20 g/L, and reaction time 180 min, with second-order rate constants of 1.10 × 10⁻³ and 1.94 × 10⁻⁵ min⁻¹respectively. The growing chelating effect between Cu(II) and HEDP and the comprehensive actions of adsorptive accumulation, direct and indirect oxidation given by particle electrodes accounted for the enhanced removal of Cu-HEDP, even though the mineralization of HEDP was mainly dependent on anode oxidation. The performance attenuation of AASB particle electrodes was ascribed to the excessive consumption of oxygen-containing functionalities during the reaction, especially acidic carboxylic groups and quinones on particle electrodes, which decreased from 446.74 to 291.48 µmol/g, and 377.55 to 247.71 µmol/g, respectively. Based on the determination of adsorption behavior and indirect electrochemical oxidation mediated by in situ electrogenerated H₂O₂ and reactive oxygen species (e.g., •OH), a possible removal mechanism of Cu-HEDP by three-dimensional electrolysis was further proposed.     

生物活性炭处理废水中有机物的研究探讨

生物活性炭(BAC)是一种处理有机废水的有效方法。现以BAC处理废水中的酚和甲醇为例,综述BAC处理废水中有机物的机理和影响因素。并通过生物活性炭吸附降解四氯乙烯(PCE)的综合模型得到BAC作用与吸附和生物降解的关系。最后简单介绍了BAC中活性炭与微生物的选择。     

白洋淀的纤毛虫及与水质污染的关系

对白洋淀纤毛虫的种类组成、优势种进行了初步调查，同时对水质进行理化监测，共鉴定出纤毛虫４８种。根据Ｍａｒｓｓｏｎ引出的污水生物体系法分析，白洋淀纤毛虫主要由耐有机污染的种群组成。说明白洋淀主要受有机污染。纤毛虫的种类数与水体中ＴＮ、ＴＰ、ＢＯＤ５有着密切关系。     

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。     

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.
