Authors: Chen Xiao Gang , Kuang Ju Chi , Chen Min Hua
Published: August 2014

In the paper we first discussed the principle of wastewater treatment by iron-carbon micro electrolysis. And the experimental methods were stated clear soon afterwards. Then we designed the micro electrolysis orthogonal experiments. Discussion of influences of related factors on waste water treatment followed. The main factors are cerium ion additive quantity, ratio of La3+/Ce4+ and pH in wastewater. The experimental results show that 1) The sequence of factors influence on wastewater micro-electrolysis treatment is Ce4+ > pH > La3+ > iron/carbon ratio; 2) The lanthanum and cerium ions have a synergistic effect in the wastewater treatment, and cerium ion plays a main role; 3) When pH is 6, COD removal rate arrives at maximum 89%, however when the pH is in the case of too high or too low, the effect of sewage treatment is not good.

Carbon accounting was carried out using Volume-Biomass Method based on field survey data from four urban parks of Dongguan. The results are as follows: 1) Shuilianshan Park (SLS) and Tongsha Park (TS) are sparsely covered with large trees, while Dapingzhang Forest Park (DPZ) and Huangqishan Park (HQS) are abundant with dense but small arbors. 2) Elaeocarpus apiculatus and Khaya senegalensis are the two major trees grown in Tongsha Park, which is located in urban core of Dongguan. A lot of individuals of Litsea glutinosa and Microcos paniculata occur in Huangqishan Park and Shuilianshan Park in the suburb, while many Acacia magium and Lithocarpus glaber trees have been planted in Dapingzhang Forest Park. 3) Carbon density and biomass density for the parks are in the following order: SLS > HQS > TS > DPZ, which reflects the gradient of rapid urbanization. Carbon sink of urban forest was affected by land-use and land-cover change, vegetation types and stand ages, reforestation, and forest management.

Authors: Jiang Li
Published: August 2014

With the increasingly development of economy in China, economic growth and efficient use of energy is a hot topic in recent years, also China is under pressure of carbon emissions reductions during the process of economic development. This paper try to do a research to find weather the structure of energy consumption and economic growth exist long-term dynamic equilibrium relationship. Based on VAR model, though Granger causality test, impulse response and variance decomposition, combined with China's development of low-carbon economy, in the years between1978 to 2012 , four results has been showed: First, China's economic growth and energy consumption exist a stable long-run equilibrium relationship. Second, at the 1% level, there is a two-way Granger causality coal consumption and economic growth. Third, in lag 4, the energy consumption is produced positive effects on economic growth and the impact of coal consumption has maximum affect. Forth, the development and utilization of renewable energy is an effective way to solve China's economic development and energy constraints contradictory.
