工业生态系统边界障碍问题研究

工业生态系统边界障碍问题是工业生态和循环经济研究领域的重要问题。目前学术界对这一问题尚未开展相关研究。结合我国当前循环经济发展所面临的向更大范围扩展的任务,对工业生态系统进行了定义并对工业生态系统边界的研究状况进行了归纳分析。在此基础上,提出并定义了工业生态系统的边界障碍问题,建立了工业生态系统边界障碍问题的研究框架,指出了开展工业生态系统边界障碍问题研究的内容。     

Volcanic hazard or economic destitution: hard choices in Banños,Ecuador

In 1999, the entire population of tourism-dependent Baños, Ecuador, some 16,000 people, was evacuated in anticipation of a violent eruption of Mount Tungurahua. Subsequently, many areas in the risk zone experienced heavy ash falls, lahars, and landslides, although no cataclysmic events occurred. Many small rural communities were also evacuated. While these communities became impacted by the hazard, Baños avoided most direct effects. Conditions for all evacuees were grim, and their conditions compounded because Ecuador was simultaneously undergoing profound economic and political crises. Absent livelihood alternatives, community leaders from Baños organized a return to their town even though it remained under an evacuation order. An aggressive campaign brought tourists and more residents back and Baños revived economically; however, this was achieved at the cost of hazard awareness among both groups, tourists and residents, and public safety became compromised.     

A cost effective method for decentralized sewage treatment

The aim of this research was to upgrade the performance of a conventional septic tank (CST) for on-site treatment of sewage with negligible costs. Although CST is known as an inexpensive pre-treatment system, a complementary treatment is required to reuse its output effluent. In this work, the quality of treated wastewater reached to the standard level for irrigation by the innovational changes made in the structure of CST for converting it into an advanced septic reactor (ASR). The modification consists adding some pipe and trays without using any mechanical or electrical equipment.ASR was operated at ambient temperatures in laboratory and pilot-scale. The effects of up-flow velocities (V_up) of 0.4, 0.5, 0.7, 1 and 1.5 m/h and hydraulic retention times (HRT) of 36, 24 and 12 h on the ASR treatment performance were studied.For optimum V_up of 1 m/h and HRT of 24 h and biomass specific methanogenic activity (SMA) of 0.31 mg COD/g VSS d the maximum removal of chemical oxygen demand (COD), biochemical oxygen demand (BOD5) and total suspended solids (TSS) were 86.2%, 79.4% and 95%, respectively.The results showed that ASR is an appropriate alternative for CST for sewage on-site treatment by a low cost modification.
