Authors: Wang Yunchen , Lu Xiwu , Cheng Fangkui 
Published: July 2020

Abstract
In order to grasp the latest changes in the quality and quantity of domestic sewage in the Taihu Lake Basin and Chaohu Lake Basin, and to scientifically guide the construction of rural sewage treatment demonstration projects, two typical villages were selected from Taihu Lake Basin and Chaohu Lake Basin respectively for fieldwork continuous monitoring of sewage water quality and quantity. The results show that the typical rural per capita daily drainage in the plain area of the Taihu Lake Basin in summer is 89.4 L·cap−1·d−1, which is significantly higher than that in the typical rural area of the Chaohu Lake Basin (56.5 L·cap−1·d−1). The amount of sewage hourly discharge fluctuated distinctly, and the coefficient of variation of sewage discharge in the two villages ranged from 2.4 to 6.1, showing obvious characteristics of “morning and evening peaks” or “morning, noon and evening peaks”. In addition, the rural sewage water quality in the two places shows the same pattern, and the pollutant concentration of sewage from different sources is significantly different. It was found that the toilet-flush sewage in Wangjiatang village provided 84.42% of TN and 92.94% of NH4
+-N in the total domestic sewage, while toilet-flush sewage in Qianying village provided 74.31% of TN and 84.56% of NH4
+-N in the total domestic. Therefore, when constructing a sewage treatment demonstration project, the ideological principles of sewage classification and treatment from the source should be considered.

Published: July 2020

Abstract
The study on the variation law and trend of rainfall characteristics of Qingshui River, a typical tributary of the upper Yellow River in China, is of great significance to reveal the cause of runoff and sediment change in the Yellow River. According to the daily rainfall data on 93 rainfall stations in the Qingshui River Basin from 1958 to 2015, the rainfall characteristics of the basin, such as annual rainfall, flood season rainfall, and main flood season rainfall were calculated. Using time-domain analogy, Mann-Kendall trend and abrupt change point test, coefficient of variation, etc., the variation and trend of rainfall characteristic values in the past 60 years were analyzed. The results showed that the distribution of rainfall during the periods from 1970 to 1979 and 2010 to 2015 was significantly different from other periods. There is no significant trend change in rainfall characteristic values from 1958 to 2015. From 1958 to 2015, the intensity of discrete changes in the rainfall characteristics of different series from small to large is the annual rainfall, flood season rainfall, and main flood season rainfall. The intensity of the discrete changes in main flood season rainfall gradually decreased with time.
Study on soil-water characteristics of unsaturated sericite schist residual soils
Authors: Liu Huan , Lian Xiao-lan , Nie Guang-ying , Zhang Qing-wen 
Published: July 2020

Abstract
The residual soil of Sericite schist softens and becomes loose when encountering water, which is easy to be damaged by wetting. Its engineering properties are obviously affected by water, so it is necessary to study its soil water characteristics. In this paper, the matric suction of Sericite schist residual soil under different dry density is measured by filter paper method. It is found that the change of soil water characteristic curve of Sericite climbing residual soil is not typical “s”, and there is no obvious unsaturated residual section. The main reason is that the residual soil of Sericite schist has sheet structure, easy drainage channel and fast water loss speed, the change of matrix suction is large. Because of its lamellar structure, its water holding capacity is poor, so the unsaturated residual section of its soil water characteristic curve has no obvious change.

Abstract
The monitoring data of chemical oxygen demand and NH3-N in the upper and lower sections of Jiamusi City in Songhua River were analyzed, and the law of water quality change in Songhua River in Jiamusi City was explored. Based on the simulation results of MIKE11 model for the water from the interval, the minimum ecological safety distance of the upper and lower reaches of Songhua River in Jiamusi city is predicted. Between the rainy season and the standard water period, the Jiamusi section meets the minimum ecological safety distance between Tangyuan County and there is no minimum safety distance during the dry season. The MIKE11 model has good adaptability to the diffusion simulation of pollutants in the upper and lower reaches of the Songhua River in Jiamusi and can be used as an evaluation basis for analyzing the impact of the water quality of the sewage outlet of the river.

Authors: Zhou Jian , Hou Meifang 
Published: July 2020

Abstract
The degradation of Orange II by the Fe0/H2O2 system was examined. The effects of Orange II concentration, H2O2 concentration, Fe0 dosage, initial solution pH value on the degradation of Orange II were investigated. The experimental results showed that Fe0 was exhibited high catalytic activity on the activation of H2O2 for the degradation of Orange II. The reactive hydroxyl radical (·OH) produced in the Fe0/H2O2 system was significant the key for the degradation of Orange II. The mechanism of the degradation of Orange II was discussed by the UV-Vis spectra analysis and determining intermediate products of the reaction solution by LC-MS. It was speculated that in the process of oxidative degradation, Orange II was first dissociated into 4-(2-hydroxy-1-naphthylazo) benzenesulfonate, and then its azo structure was oxidized and destroyed by hydroxyl radicals (·OH). Secondly, the reaction solution faded to produce benzenesulfonate and 1, 2-naphthoquinone, and then 1, 2-naphthoquinone was further oxidized by ·OH to phthalate. Finally, phthalate and benzenesulfonate could be further mineralized into CO2, H2O and SO4

Published: July 2020

Abstract
In recent years, the 3D fluorescence excitation emission spectrum has been widely applied into the analysis of the properties of soluble organic matter in water bodies, but there is very little research on the fluorescence properties of protein residues in water quality detection by Fluorescence Excitation Emission Matrix (FEEM), and synchronous fluorescence excitation emission spectra (SFS). The characteristics of luminescent of amino acids, including tryptophan, tyrosine and phenylalanine, where tryptophan and tyrosine fluorescence are relatively strongest, and the effects of tyrosine on the fluorescence properties of tryptophan are seldom discussed in different mixing ratios for both amino acids. The fluorescent peak positions and intensities of the three amino acids are related to the angle size of conjugate plane, N hybrids and hydroxyls on benzene rings. When the ratio of tyrosine to tryptophan content is less than 150:100, tryptophan will quench the fluorescent peak of the tyrosine. Constant tryptophan content, tyrosine at excitation wavelength of 228 nm, its concentration changes with the corresponding fluorescence intensity has a good linear relationship; however, at 276-278 nm of tyrosine, the varied concentrations and fluorescence intensities are opposite.

Abstract
in order to explore the effect of biochar on cement properties, wheat straw biochar (WS) and rice straw biochar (RS) were pyrolyzed at 300 °C, 500 °C and 700 °C to replace cement with 1% and 2%, and their compressive strength and thermal conductivity were measured. The results showed that the compressive strength of the cement block with biochar increased significantly at 500 °C and 1% cracking temperature, and the compressive strength of the two biochar increased by 31% and 29% respectively The thermal conductivity and thermal diffusivity of two kinds of biochar are decreased, and the thermal insulation performance is improved. The thermal conductivity of rice biochar at 700 °C was the lowest with 2%, and the thermal diffusivity of wheat biochar at 700 °C was the lowest with 2%. It provides a new way to predict the thermal properties of cement-based materials with low thermal conductivity. At the same time, these properties and laws of biochar can also be applied to cement processing, cement thermal conductivity research, material preparation and other practical applications, in order to create better social, economic and ecological benefits.

Abstract
In recent years, the development of electric vehicles has made remarkable achievements. Its popularization and application can alleviate the problem of energy shortage and environmental pollution to some extent. In the process of discharging, the battery will generate heat. If the heat cannot be transferred to the external environment in time, the normal operation of the battery will be affected. In this paper, a BTM system based on PCM/micro-channel cooling is designed, and its cooling effect on battery module is studied by numerical simulation. The electrochemical-thermal coupling model is established to study the heat production and temperature changes of the battery during discharging. The cooling effect of the flow rate at the inlet of the cooling plate and the thickness of PCM on the battery module is studied. The results show that the BTM system can not only reduce the maximum temperature of the battery module, but also effectively improve the temperature inhomogeneity among the batteries.

Published: July 2020

Abstract
This paper constructs the competitiveness evaluation model and indicator system of inland port from three aspects of infrastructure, production capacity and development environment. The competitiveness of 31 major ports in the four river systems is measured by analytic hierarchy process and correlation coefficient method. According to the competitiveness evaluation results, K-means clustering analysis is carried out for inland ports by SPSS software. The results show that the competitiveness of inland ports in China is relatively low, and there is a significant gap between the competitiveness of ports in the same river system and different river systems. Each port has its own competitive sources. Highlighting the development advantages of each port and making up for the shortcomings will help to improve the efficiency of port resource allocation.
