Alkaline hydrothermal conversion of fly ash precipitates into zeolites 3: the removal of mercury and lead ions from wastewater

In this paper, the utilisation of zeolites synthesised from fly ash (FA) and related co-disposal filtrates as low-cost adsorbent material were investigated. When raw FA and co-disposal filtrates were subjected to alkaline hydrothermal zeolite synthesis, the zeolites faujasite, sodalite and zeolite A were formed. The synthesised zeolites were explored to establish its ability to remove lead and mercury ions from aqueous solution in batch experiments, to which various dosages of the synthesised zeolites were added. The test results indicated that when increasing synthesised zeolite dosages of 5-20 g/L were added to the acid mine drainage (AMD) wastewater, the concentrations of lead and mercury in the wastewater were reduced accordingly. The lead concentrations were reduced from 3.23 to 0.38 and 0.17 microg/kg, respectively, at an average pH of 4.5, after the addition of raw FA zeolite and co-disposal filtrate zeolite to the AMD wastewater. On the other hand, the mercury concentration was reduced from 0.47 to 0.17 microg/kg at pH=4.5 when increasing amounts of co-disposal filtrate zeolite were added to the wastewater. The experimental results had shown that the zeolites synthesised from the co-disposal filtrates were effective in reducing the lead and mercury concentrations in the AMD wastewater by 95% and 30%, respectively.

A BASKET SAMPLING TECHNIQUE FOR QUANTIFYING RIVERINE MACROBENTHOS1

ABSTRACT: A colonization basket sampling technique for quantifying macroinvertebrates in rubble bottom rivers is described. Basket samplers were compared to collections made using the Surber square foot sampler. Procedure for processing samples is described. Macrobenthos were more accurately quantified by basket samplers because both surface and subsurface habitats were sampled, no organisms were lost when samplers were removed from the river, substrata and associated fauna were retained for analysis, and the samplers were used efficiently in both pool and riffle areas. At the end of the colonization period the basket samplers contained one-half cubic foot of river bottom and macroinvertebrates spatially arranged within.     

STREAMFLOW MODELING OF UPPER INDUS RIVER CATCHMENTS1

ABSTRACT: The streamflows of three tributaries, Siran, Haro, and Soan in the upper Indus River catchment in Pakistan were simulated using SSARR and Tank Models. Channel characteristics of the main Indus River were also determined using the two models. The basin characteristics were derived by trial and error method and were verified using the data for the period 1964–1970. Comparison of the two model performances showed that low flows were better reproduced by SSARR while the high flows were simulated with equal accuracy by both the models.     

Solidification of tannery wastes

The high chromium concentrations in tannery-wastewater treatment-plant sludges, render them unsuitable for direct disposal. Therefore, one aims to fix the chromium of the tannery waste by adding different additive materials to cause solidification. The properties of the raw sludge were determined and subsequently, the sludge was mixed with cement and additives and left to solidify for 28 days. During the study, 28 different mixtures were prepared and their compressive strengths were determined. Standard elutriation tests were carried out with each solidified sample. Compressive strengths were obtained below the desired concrete strengths. Most of the pollutant parameters in eluate were under the required values.     

贵州桦木资源现状与开发利用策略

贵州桦木种类有7个,其中桦木属有4个种,桤木属有3个种。光皮桦和旱冬瓜是分布最广的两个种,全省各地均有分布。传统林业主产区的现有桦木资源数量比非主产区小,现有桦木资源以中、幼林为主,中、幼林的面积和蓄积超过98%,近、成熟林和过熟林资源相对非常少。贵州桦木资源开发利用应系统开展良种选育研究,加强抚育管理、综合改造"三低"林分,科学规划、合理布局良种基地,采用良种良法营造高效用材林基地。

Integrating Environmental Characteristics and Fisheries Management in Northern Finland River Impoundments

/ Three large rivers in northern Finland, the Kemijoki, Iijoki, and Oulujoki rivers, were dammed for hydropower generation in the 1940s-1960s. Due to differences in environmental conditions, these impoundments require detailed study to produce guidelines for fisheries management.Water quality, hydrology, vegetation, and geomorphology data of 16 impoundments were gathered. Shoreline land-use data were derived from maps, and fish assemblage data were collected by exploratory fishing and from the annual fishery statistics. The relations among environmental variables were studied, and a classification of the impoundments was developed by hierarchical cluster analysis. Consequently, three impoundment groups with different environmental characteristics were formed. Significant differences among impoundment groups were also detected in fish yield. We conclude that the variation in environmental conditions, together with differences in fish communities in the impoundments were important enough to justify the claim that impoundments of different types require different management strategies. KEY WORDS: Impoundments; River regulation; Fish assemblage; Water quality; Aquatic vegetation; Finland

基于价值取向的城市森林游憩服务需求研究

在调查南京城市森林游憩者的基础上,以森林价值取向为预测变量,对城市森林游憩服务需求进行了研究.研究表明,市民的森林价值取向包括生态取向、健康取向、文化取向、产品取向和消极取向五种类型;城市森林游憩服务需求则包括基本需求、拓展需求和个性需求三个层次.通过典型相关分析发现,对森林资源持“健康”、“文化”和“生态”价值取向的市民对森林游憩的“基本服务”需求明显,更重视森林的自然和文化环境保护;而持有“产品”和“消极”取向的市民,则希望森林游憩地能提供更多“拓展”和“个性”服务.在此基础上,提出了积极引导城市森林游憩者的政策建议.
