剩余污泥处理新工艺

研究了剩余有机污泥处理新工艺，将剩作污泥进行酸化水解后回到废水处理系统一起代谢，基本达到无污泥排放。该工艺适合于染整废水、乳品厂废水处理站等有机污泥处置，特别适用于泥难以脱水的如锦纶厂废水处理站的剩余污泥处理。     

呼伦贝尔草原优良牧草及土壤中有机氯农药残留量调查研究

本文根据内蒙古地区草原牧草及土壤中有害物质现状调查技术规范，对著名的畜牧业基地──呼伦贝尔草原优良牧草及土壤中有机氯农药（六六六、ＤＤＴ）残留量进行了调查研究。结果表明，这两种有机氯农药在呼伦贝尔草原牧草及土壤中的残留量低于内蒙古地区的平均水平，更低于国家粮食作物及土壤卫生标准。但其化学性质稳定、脂溶性强，应停止使用。

Influence of organic ley–arable management and afforestation in sandy loam to clay loam soils on fluxes of N2O and CH4 in Scotland

Assessment of the sustainability of alternatives to conventional uses of agricultural land, viz. organic systems and afforestation should include consideration of any effects on trace gas budgets. Nitrous oxide (N₂O) and methane (CH₄) fluxes and controlling soil properties were measured in an organic ley–arable rotation in north-east Scotland on a sandy loam. N₂O fluxes were monitored in the ley and arable phases and in organic permanent grass (Lolium perenne) located nearby throughout the 3-year phase duration. Gas fluxes in woodland that had been converted from arable for 1 or 6 years were also measured in both north-east and south-east Scotland on sandy loam to clay loam soils. The climate is maritime and variable with annual rainfall between 800 and 900 mm. Within the organic rotation, differences in N₂O fluxes between the ley and arable phases were less marked than in conventional agriculture. Although this was mainly because grassland emissions were low, some losses from the arable component were also relatively high. Seasonal rainfall had a major influence on cumulative emissions of N₂O, including the first year after conversion from ley to arable. In the short term, changing land use from arable to woodland increased CH₄ oxidation rates and decreased N₂O emissions, though both these rates were also influenced by seasonal weather. Afforestation of agricultural land appears to be more beneficial to trace gas exchange than conversion to organic production.     

生物接触氧化法处理有机废水的进展

水源有机污染对饮用水质的影响研究

对松花江S水源地及H市饮用水进行连续监测,江水中定性检出的有机污染物,在饮用水中绝大多数都可以检出,说明水厂传统的常规处理工艺对于有机污染物去除率较低,致使一些有机污染物残留在饮用水中,对沿江居民健康产生危害.     

有机絮凝剂PYM絮凝特性的研究

以乙二醛、腈类及改性剂制得有机絮凝剂ＰＹＭ，对水溶性染料活性艳红Ｘ－３Ｂ、酸性大红ＧＲ直接耐晒黑Ｇ等模拟废水及化工染料废水的净化效果和脱色机理进行了研究，结果表明，ＰＹＭ的净化效果与染料的种类、废水酸度及投量有关在适宜条件下，均可取得脱色率９７．０％～９９％、ＣＯＤ去除率达６５％～８６％的较好效果，脱色机理的研究结果表明，絮凝剂中的＝ＮＨ＾＋２结构与活性艳红中的－ＳＯ３－结合，同时分子间亦形成氢键
