活性污泥二次污染问题的探讨(Ⅱ)

讨论了城市污水经过A／O工艺处理时活性污泥的二次污染问题。将原水、处理后的出水及活性污泥用甲苯萃取，萃取相经过真空浓缩后，采用GC／MS测定了样品中的有机化合物，结果表明，在A／O工艺处理城市污水过程中，活性污泥的吸附作用是主要的，降解作用是次要的；A／O工艺所排放的活性污泥仍然是一种危险的污染物。     

宁波市城市污水处理厂污泥处置方案探讨

随着城市污水处理率提高导致的污水污泥产量的增长趋势也使得污水污泥的处理问题更为突出。在总结国内外城市污泥处置技术发展趋势的基础上,结合宁波市的实际情况,根据无害化、减量化和资源化的原则,提出城市污泥近远期处置方案,并对处置方案作出可行性分析。     

Acute toxicity of two insecticides to tubificid worms, Tubifex tubifex and Limnodrilus hoffmeisteri

Acute toxicity and presumable harmless concentration of two commercial insecticides, Furadan 3G and Malataf 50E were reported for tubificid worms, Tubifex tubifex and Limnodrilus hoffmeisteri. L. hoffmeisteri were found more susceptible to both the insecticides; the Furadan was found to be more toxic than Malataf to tubificid worms. Analysis of variants showed a significant difference between safe concentrations of the same insecticide to different species.     

我国公众环境保护意识的调查与分析

本文根据一次大规模的抽样调查资料，初步分析了我国公众环境保护意识的现状，认为从总体上看，公众的环保意识水平偏低；公众的环境资源况颇具特色；在经济发展与环境保护之间出现明显矛盾时，半数公众能够优先考虑环境保护；大多数公众认为环境保护与个人有关，但对个人的努力信心不足；超过七成的公众表示愿意为环境保护支付一定费用，但对高收入阶层普遍寄予较高的期望；公众有一定的依法保护环境的心理基础，但法律知识又非常缺乏。     

The 2030 Agenda for Sustainable Development and China’s implementation

The concept of sustainable development has experienced great development and change at different levels of theoretical connotation and practical implementation since 1960s and 1970s when it was first proposed. People’s understanding of the relationship between economy, society, and environment has been continuously deepened over the years. When it came to the end of 2015, it is necessary to examine the results of the United Nations Millennium Development Goals on sustainable development, and at the same time, the post-2015 framework and guidance on sustainable development at the global level were to be made, including the ideas, action plans, key areas that would guide the global sustainable development. The 2030 Agenda for Sustainable Development has developed a 5P theoretical framework of being people-centered, global environmental security, sustained economic prosperity, social justice and harmony and partnership promotion, including a political declaration, 17 overarching goals and 169 specific targets, specific ways of implementation, as well as the follow-up. It is the road map to achieve global sustainable development and meet the requirements of the millennium development goals. This paper summarizes the understanding of the concept of sustainable development from its origin, its significant development, to the proposition and development of the 2030 Agenda for Sustainable Development, and its strategic impact on China.     

适用于我国农村地区的低温空气源热泵采暖技术

基于我国农村特点提出采用清洁能源利用技术——低温空气源热泵采暖方式替代农村传统的散煤燃烧取暖方式。低温空气源热泵采用较为成熟可靠的补气增焓技术。研究表明:在蒸发温度为-30 ℃、冷凝温度为45 ℃、补气比为0.6的模拟工况下运行,低温空气源热泵理论制热性能系数(COP)大于2.25,系统能效比(EER)高于1.90。在实际应用过程中,低温空气源热泵机组可解决不同场合下需依靠不同介质(热风或热水)采暖的问题,预计全面推广后,我国农村地区每年可减少二氧化碳、二氧化硫、氮氧化物和粉尘排放分别约3.86亿、0.115亿、0.057亿和1.05亿t,其可作为淘汰农村传统采暖方式的优先选择。     

Engelbart SST工艺农村生活污水一体化治理设备的应用效果及运行能耗

针对农村生活污水水质水量波动性大的特点,应用基于Engelbart SST工艺的一体化处理设备对农村生活污水进行了处理,并考察了该设备在水质波动情况下的处理效果与运行能耗。结果表明,在DO为0.3~0.5 mg·L⁻¹、回流比为1 000%~2 000%、HRT为12~15 h、MLSS为5 600~8 800 mg·L⁻¹的工艺条件下,配合化学除磷,设备COD、NH₃-N、TN、TP平均去除率分别可达到95.3%、94.9%、78.9%、92.2%。该设备表现出了良好的抗波动能力,在COD、NH₃-N、TN处理负荷较设计值波动幅度分别为−39.7%~171.0%、−34.8%~96.9%、−45.0%~61.1%的条件下,出水COD≤50 mg·L⁻¹、NH₃-N浓度≤5.0 mg·L⁻¹、TN浓度≤15 mg·L⁻¹。该设备利用曝气自动控制系统在经济DO条件下运行,吨水能耗为0.24~0.33 kWh。本研究结果可为农村污水处理的技术选择和运行提供参考。
