TS-35型氨法脱硫工业化试验及其经济性分析

对TS 35型氨法脱硫工艺进行了系统的工业化试验研究 ,该脱硫工艺对原有锅炉参数影响小 ,氨水消耗量少 ,阻力小 ,能耗低 ,脱硫效率可达 80 % ,几乎无废水排放 ,适用于中小型锅炉的脱硫 ,但有可能会加剧锅炉尾部设备的腐蚀。对于大型锅炉 ,必须考虑副产品硫酸铵的销路和价格问题。通过经济性分析 ,得出目前实施的排污收费制度存在一定的弊病 ,有必要完善以总量控制为目标的排放许可权交易制度     

Carcinogenic effect of potential toxic metals in school children through contaminated drinking water around the industrial area of Pakistan

Due to papulation increase in Pakistan the demand of drinking water increased day by day. After the industrial grooming the wastewater producing harmful effect on the surrounding area of industries and drinking water contamination increased. Pakistan is on 82 amongst the 125 countries of the word having drinking water problem. Different parameter set by World Health Organization (WHO) and Pakistan Environmental Protection Agency (Pak-EPA) of hazard dimension index (HD) and Lifetime Cancerogenic risk Calculation (LFCR) of Potentially toxic metals that are As, Cd, Cr, Ni, Pb (PTMs) are higher, and the school age children are under high risk of cancer. All the drinking constraints set by regulating authority is fully neglected by inopportune human process by solid waste dumping and houses and industrial disposal with any proper treatment. This study discusses all the HD and LFCR parameter in three age group children, male and female through drinking water around the Hattar Industrial Estate (HIE) in Pakistan. In children and women more HD and LFCR thread than the adult man. The overall result shows that the HD risk is higher than the LFCR due to the PTMs in drinking water only HD is exceed from the limit of WHO and Pak-EPA. If there is no proper arrangement take place for the removal of As and PTMs from the industrial wastewater and drinking water than within few years all the population around the study area effected with different type of cancer.     

洪湖营养盐时空分布特征及成因分析

洪湖是江汉平原重要的淡水水体.为了揭示洪湖营养盐时空分布特征和原因,开展了对洪湖为期一年的采样调查,连续采集12个月水样和一次沉积物样品,测定样品中营养盐含量.结果表明:(1)洪湖水体营养盐污染水平较高,除氨氮(NH4+-N)外,总氮(TN)、总磷(TP)和高锰酸盐指数(CODMn)难以达到Ⅱ类.(2)空间上有机物污染...     

The Status of Pesticide Residues in the Drinking Water Sources in Meiliangwan Bay, Taihu Lake of China

The study was carried out to assess the levels of pesticide residues in the water of Meiliangwan Bay, Taihu Lake of China. The most commonly employed organochlorine pesticides (OCPs), organophosphorus pesticides (OPPs) and herbicide atrazine were analyzed. The water samples were collected seasonally from Meiliangwan Bay within a period of one year. The pesticides were analyzed by gas chromatography (GC) with μECD or NPD after solid-phase extraction (SPE), which was confirmed by GC with an ion trap mass spectrometry (MS). The mean concentrations were 1.98 ng/l for lindane, 0.378 ng/l for heptachlor epoxide, 0.367 ng/l for p,p′-DDE, 0.496 ng/l for p,p′-DDD, 1.06 ng/l for p,p′-DDT and 51.6 ng/l for dichlorvos, 39.0 ng/l for demeton, 346 ng/l for dimethoate, 4.12 ng/l for methyl parathion, 11.6 ng/l for malathion, 2.17 ng/l for parathion and 217 ng/l for atrazine. Generally, low concentrations of OCP were found, whereas the concentrations of the OPPs and atrazine in the water of Taihu Lake were relatively high. Heptachlor epoxide and lindane were the two most commonly encountered OCPs while dichlorvos, demeton and dimethoate were found to have much higher concentrations and occurrences than other OPPs.
