Airsolution液体在净化有机废气方面的应用

Airsoluton是一系列植物提取液复配而成的,这些植物提取液是含有气味的有机物,它们是从树、草和花等植物中提取的。这些有味的液体含有大量复杂的化合物,它们是绝大多数植物油的主要成分。本文根据Airsolution液体的氧化性,对处理含苯、甲苯和二甲苯的有机工业废气进行了净化研究,结果表明:Airsolution液体用于处理有机废气是可行的,处理后的苯、甲苯和二甲苯可实现达标排放。且该工艺具有运行费用低,投资少的特点。     

活性炭吸附处理洗毛废水的研究

通过活性炭吸附两种不同处理方法处理后的洗毛废水。研究了活性炭的吸附容量和吸附机理。结果表明：活性炭吸附无机酸酸化处理后,废水和高分子絮凝剂处理后,废水中COD的吸附容量分别为：70mg／g和43mg／g。进一步研究发现,两种废水中小分子组分和疏水性组分的含量差异是造成活性炭吸附效果差异的主要原因。     

Study on bioremediation of eutrophic lake

Bioremediation is considered as one of the effective ways to deal with the pollution of natural water because of its high efficiency, low cost and causing no secondary pollution. The multiple microbial preparation is composed of bacteria that can transfer nutritive material harmless and some natural humic acid which can destroy algae. The qualified bacteria were selected, separated, and enriched from the water and bottom sediment of eutrophic lake. A field trial of bioremediation was carried out in 60 m³ of eutrophic water body in Yingze Lake of Anshan for four months. TN (total nitrogen), TP (total phosphorus), ammonia nitrogen, COD_Cr, and turbidity of the trial water and untreated water were measured termly. Contrastive analysis showed the mulriple microbial preparation can increase the water capacity of self-purification, decrease the turbidity, inhibit algae growth and improve water quality gradually at substantially lower cost. Thus the problem of lake eutrophication can be solved radically by bioremediation.

污泥对樟子松生物量及其重金属积累和土壤重金属有效性的影响

采用盆栽试验研究了不同剂量污泥(体积分数,即污泥体积占污泥和沙土总体积的百分比,分别为:0、20%、33.3%、50%和100%)施用于风沙土条件下,污泥剂量对樟子松幼苗生物量及其对重金属的累积和土壤中重金属有效性的影响.结果表明,在养分含量低的风沙土中,施用污泥能够显著提高樟子松幼苗生物量,最适剂量为50%;污泥剂量的增加可促进樟子松植株对重金属的吸收和累积,在最适剂量(50%)条件下,樟子松植株中Cu、Cd、Pb、Zn的累积量分别是对照(不施污泥)的18.0、8.9、17.1、11.5倍;樟子松植株重金属吸收速率顺序为:ZnCuPbCd,而迁移系数顺序为:ZnCdCuPb;土壤中有效态重金属含量随污泥剂量的增加而增加,而植株收获后土壤中有效态重金属下降幅度均小于对照.     

Effect of lime application on microbial community in acidic tea orchard soils in comparison with those in wasteland and forest soils

Lime application is a conventional technology to control acidification in tea orchard soils. We investigated the e ect of lime application on soil microbial community diversity in the soils of three tea orchards, wasteland and forest. The BIOLOG data showed that both the average well color development of all carbon sources and the functional diversity index increased with the liming rate in the tea orchards and the forest, but decreased in the wasteland. The phospholipid fatty acid (PLFA) analysis showed that the structural diversity index of soil microbial community increased with the liming rate in all the tea orchards, the wasteland and the forest. Lime application also increased the soil-bacterial PLFA content in all the soils. Soil fungal and actinomycete PLFAs in the tea orchards showed an increasing trend from 0 to 3.2 g CaCO3/kg application and then a decreasing trend from 3.2 to 6.4 g CaCO3/kg application. The principal component analysis of BIOLOG and PLFA data suggested that lime application had a significant e ect on soil microbial community structure, and land use had a greater e ect on soil microbial community structure compared to lime application.     

几种海藻表面附着细菌的分离及其gyrB基因序列分析

利用TCBS培养基从三种海藻:孔石莼(Ulva pertusa)、海带苗(Laminaria japonica)和多管藻(Polysiphonia urceolata)表面共分离得到10株细菌.生理生化试验和gyrB基因序列分析结果表明10株细菌都属于弧菌(Vibrio).基于gyrB基因序列构建的系统发生树显示,菌株L5、L6、P7、P8、P10、P11、P12与Vibrio splendidus属于同一分支,序列间相似性为97.5-100%.菌株L4、P9与Vibrio cyclitrophicus属于同一分支,序列间完全一致.菌株U3在系统发生树上独立构成一个分支.本文结果表明不同海藻表面的附着细菌组成也不相同,具有一定的海藻特异性.     

HSE管理体系风险评价中的常见问题

风险评价和隐患治理是中国石化HSE管理体系的基础要素和核心要素,其运行质量直接关系到HSE管理体系运行的有效性。近年来在HSE管理体系审核中发现,部分企业对此要素未能按标准的要求实施,影响了风险识别、评价和控制的充分性和有效性。     

宜兴市土地利用类型与水生态健康相关性研究

利用宜兴市2012年-2014年土地利用数据、水生态健康等相关数据,引用土地利用动态度和土地利用综合程度指数,对土地利用变化和水生态健康现状进行分析,运用相关性分析法测算土地利用类型比例与水生态健康主要指标的相关性.结果表明:耕地、建设用地比例与水生态健康综合指标负相关,湿地、草地、园地、林地用地比例与水生态健康综合指标正相关;建设用地比例与底栖动物负相关;湿地用地比例与营养、底栖动物指标正相关较强.
