Authors: Xiao Kun , Zhang Jingdong 
Published: December 2019

Abstract
Emission of air pollutants from the power generation industry is a major cause for severe air pollution prevention in China. Identifying the important driving factors of air pollutant emissions from power generation, and evaluating the importance of these factors are of great significance to formulate air pollution prevention policies. Based on the classic STIRPAT model, this paper expands the indexes of relevant economic, social and technical factors, and creatively takes the input of power generation environmental protection facilities as an important technical factor to evaluate the contribution of these factors to two typical air pollutants (SO2 and smoke dust) of power generation. The empirical study results show that the indicators of economic, social and technical factors proposed and expanded in this paper are significant and effective, and “annual operating cost of industrial waste gas treatment facilities”, “power consumption intensity of secondary industry” and “power generation structure” are the variables that have the strongest impact on the emission of two typical air pollutants of power generation. These empirical study results provide scientific guidance for further policy making.

Published: December 2019

Abstract
The dry-spun acrylic fiber wastewater is characterized by its complicated components and high volatility of water quality. Therefore, it is typically difficult to treat. In this paper, the advanced treatment of dry acrylic plant effluent was treated by the joint process of ozone/ultraviolet-biological aerated filter (O3/UV-BAF). The effects of ozone dosage and pH on ozone to degrade COD were discussed, and under the condition of the process running steadily, the removal effect of each unit on COD was investigated. The results showed that with the increase of ozone dosage, the increase of COD removal was generally shown as a slow first, then a fast and then a steady trend. In the ozone dosage from 52.6 to 63.2 mgL-1, the COD removal rate reached 32.7% to 35.3%, and had the best economic feasibility. At pH 9 or so, the COD removal was the highest. The average removal of O3/UV for COD was 32.0%, the average removal of BAF for COD was 32.6%, and the average COD concentration of effluent was 83.4 mgL-1, met its first class discharge standard.

Published: December 2019

Abstract
The environmental pollution cost is a measure of the extent of damage to the environment of land development projects. It should be an important part of corporate decision-making. Environmental pollution cost refers to economic losses caused by environmental pollution, including environmental degradation cost and pollution control cost. First, we use the market value method to establish the cost equations for water, energy and land environmental degradation. In addition, we use principal component analysis to select two main factors affecting environmental control cost: environmental pollution level and corporate environmental management level. We use the entropy weight method and the analytic hierarchy process to normalize the management level, and then establish an equation for accounting for the pollution control cost of the project. Enterprise environmental pollution cost accounting system is conducive to the enterprise to accurately calculate the environmental pollution cost of land development projects. Reasonable control of environmental pollution is conducive to the sustainable development of the economy and society.

Authors: Zhang Lu , Hu Ya 
Published: December 2019

Abstract
The purpose of this study is to ecologically soil, reduce fertilization and maintain land productivity. In this study, the amount of nutrient elements stored in the soil is large, and the soil samples are treated with long-term constant and different water content to determine the activation amount of the solid elements in the soil. The results showed that the content of available phosphorus and available potassium released by XH6 in different water content cultures was higher than 3.89% and 10.12% of XH10, respectively. The content of nitrate nitrogen released by XH4 was higher than that of treated XH4. %. The content of ammonium released under treatment of XH10 was higher than that of treatment with XH10 of 24.11%. The release nutrients varied with the culture time, but the release of nutrients such as ammonium nitrogen, nitrate nitrogen, available phosphorus and available potassium peaked on the 14th day of culture, and stabilized in the latter culture. So, the high moisture content has a certain release and increase effect on soil available potassium and available phosphorus.

Abstract
Through comparing national, provincial and municipal standards in rural domestic sewage treatment, appropriate standards and indexes are chosen to implement rural sewage treatment in Ningbo. Among some commonly used rural sewage treatment processes under such climate as Ningbo, there are four most often used processes in the first phase of Ningbo from year 2009 to 2012. In order to assess the effluent treatment effects, four typical sewage quality indexes, which are CODCr, SS, TN and BOD5, are chosen to assess effluent qualities in four typical processes. The investigation results show that every process of the four typical processes has its advantage in rural sewage treating, and there is no process can remove all the sewage pollutants to the most simultaneously. The operation results of different processes are compared in details in this paper. Through the research, it can help to eliminate inappropriate processes and explore some suitable processes for rural domestic treatment. As a result of the research of rural sewage treatment processes in Ningbo, two kinds of typical composite processes are respectively demonstrated in different occasions in water-source-protecting areas and non-water-source-protecting areas.

Abstract
Active ions in acid rain may decrease the electrical performance of the insulation outside the electrical equipment. The relationship between acid-rain pH value and fog-water conductivity is studied in this paper. It is found that the acid rain ion component and pH value are very correlated with local air pollution. The pH value and conductivity of sediment water in different areas may be different. The conductivity γ-value of acid precipitation decreases with the increase of pH value. The external insulation electrical test can be carried out by adjusting fog water conductivity equivalent simulation of acid wet sedimentation.

Published: December 2019

Abstract
With the development of social economy, environmental protection has become a hot topic. Excessive emissions of agricultural chemicals increase the accumulation of the heavy metal cadmium (Cd) in soil. When plants are stressed by high concentrations of heavy metals, their antioxidant capacity and detoxification capacity will decrease, which will lead to damage the cell mechanism of plants. Glutathione (GSH), as an important water-soluble antioxidant in the organism, can enhance plant resistance in stress. This study used cucumber seedlings as test material, using hydroponics, to research the effects of exogenous GSH on antioxidant system under Cd stress. The study showed that exogenous GSH could enhance the antioxidant capacity of cucumber leaves under Cd stress and increase the activity of SOD and POD, and reduce the content of MDA. However, the contents of reduced GSH and GSSH were reduced when exogenous glutathione was applied under Cd stress.

Authors: Tingting Shi , Fang Chang 
Published: December 2019

Abstract
An investigation was conducted on 21st April 2012 in Southampton Water sediment, with the aim of detecting the contaminants distribution and the influence on the living organisms. Among the sampling sites, station 3 and 4 are most close to Fawley oil refinery, where contaminants with respect to trace metals, Cu and Zn, and oil are observed with highest concentrations. Metals contained in the sediments are in forms of weakly bounded compounds, such as carbonates and oxides, or strongly bounded complex, including organic metals and sulphide. High values of organic matter concentration in sediment at station 3 agree with the oil release from Fawley. Chlorophyll a concentrations are lowest at station 4, corresponding to the high pollution around.
