Published: May 2020

Abstract
In order to explore the removal effect of styrene waste gas by bioscrubber with multi-sided hollow spheres as filler, the residence time, circulating liquid pH and gas-liquid ratio were taken as experimental factors, and the removal rate of styrene was taken as the response value. The experiment was designed according to Box-Behnken, and the response surface analysis method was adopted to establish the corresponding predictive regression model and conduct the analysis of variance. The optimization module of Design-Expert software was used to optimize the optimal combination of all process parameters: the residence time was 43.18 s, the pH of circulating liquid was 7.61, and the gas-liquid ratio was 3.95. Under this condition, the removal rate of styrene was 88.52%. The influence of different fillers on the purification performance of biological tower was compared and analyzed, so as to provide the basis and basis for the application of efficient VOCs processing technology in bioscrubber.

Authors: Jin Ru , Li Fei , Gao Yijian 
Published: May 2020

Abstract
With the rapid growth of China’s economy since the start of the 21st century, the development and utilization of coastal areas have also experienced rapid expansion. With the continuous and high-intensity agglomeration of social and economic factors such as city, industry and population in coastal areas, the fragile and sensitive coastal ecosystem is under great pressure of resources and environment. In this study, we propose a theoretical and methodological framework for the comprehensive evaluation of the sea area carrying capacity to systematically evaluate the coupling and coordination of resources, environment and development in coastal areas. This framework includes 12 representative indicators of three factors: spatial resource endowment, ecological environment pressure and development and utilization intensity. Taking Yancheng sea area of China as an example, we analyzed the development and change of sea area carrying capacity from 2000 to 2015. The results show that the carrying capacity score of Yancheng sea area decreased from 3.12 in 2000 to 1.58 in 2015, indicating that the comprehensive carrying capacity of the sea area in this period is facing an unsustainable severe situation. At the same time, with the development intensity index score increasing from 0.62 to 0.92, the resource endowment index and ecological environment index scores decreased from 0.98 to 0.75 and 0.95 to 0.70, respectively, indicating that the continuous high-intensity development activities in Yancheng sea area during this period put great pressure on resources and environment. This framework can provide technical support for the balance of economic development and the protection of resources and environment in coastal areas.

Authors: Zhang Pan 
Published: May 2020

Abstract
The effect of light burned magnesia on the performance of sleeve grouting under different content gradients was studied. The results show that the light burnt magnesia content has no significant effect on the fluidity of the grout when it is less than 5%. The incorporation of light burned magnesia improves the compressive strength of the sleeve grout and the expansion rate of 14d∼56d in restrict condition. The incorporation of light burned magnesia can effectively solve the problem of shrinkage of the grouted slurry volume in the later stage and improve the compressive strength of the sleeve grout.

Published: May 2020

Abstract
Stray current can cause severe corrosion on buried steel pipelines. To investigate the corrosion effect of stray current, originating from impressed current cathode protection system of pipeline, on interference pipeline, a numerical model based on boundary elements using commercial software COMSOL Multiphysics was developed to simulate corrosion potential and stray current density distribution on interference pipeline. The model geometry was comprised of the cathodically protected pipeline, interference pipeline and an auxiliary anode. The effects of crossing angle and crossing distance of the two pipelines, output current and location of anode, soil resistivity and coating surface resistivity were investigated. The results demonstrated that the impressed current cathode protection system substantially affects the corrosion potential and current density distribution of interference pipelines in vicinity of crossing. The crossing angle and vertical distance of two pipelines have no important influence while the anode output current, anode location, soil resistivity and coating surface resistivity have significant influence to stray current corrosion on interference pipeline.

Abstract
Spectrophotometric determination of acetylcysteine by Cu(I)–neocuproine is studied. The hydrosulfuryl(-SH) in acetylcysteine can reduce Cu(II) to Cu(I), then the chromogenic reagent of neocuproine react with Cu(I) to form the yellow complex. The yellow complex has the maximum absorption at 453 nm, and the amount of yellow complex is proportional to the amount of acetylcysteine in a certain range. Therefore, the content of acetylcysteine in medicine can be determined by measuring the absorbance of the yellow complex.

Published: May 2020

Abstract
Cations such as Ca2+, Mg2+, Fe2+ etc. in recycled produced water seriously affect the viscosity and stability of movable gel. Four types of polymers were evaluated in laboratory including comb-shape polymer and hydrophobically associating polymer. By analyzing two types of polymers’ molecular structures, it showed that comb-shape polymer was easier to improve its properties by cross-linking reaction, and the viscosity of the hydrophobically associating polymer mostly came from the viscosity of molecular structure. Cross-linking reaction contributed little to the viscosity of hydrophobically associating polymer. The movable gel was prepared in salt water of TDS=2.64×104mg/L by using comb-shape polymer B and modified phenolic resin prepolymer. By introducing rigid benzene ring structure, the salt tolerance and long-term stability were significantly improved. The viscosity of retain rate was more than 70% after 60d under 90°C. Field application of 3 wells showed that qualification rate of preparing movable gel was 100% and oil increment was 3020t.

Abstract
A series of supported vanadium-titanium denitrification catalysts were prepared by impregnation method with foam metal as carrier for NH3-SCR of NOx at low temperature. Effects of pH, slurry concentration, catalyst loading rate, face velocity and O2 concentration on catalytic performance were studied. The results showed that when immersion concentration was 30g/100mL and filtration speed was 0.7m/min, the pressure drop was 300Pa and NOx removal efficiency was 98% at 200°C. The foam catalytic filter was put into the bag dust collector, which had the function of simultaneous removing particulate and NOx. When filtration velocity was 0.7m/min, NOx removal efficiency reached 95.5% at 200°C and it had good water resistance. The results provided the basis for further pilot experiment.

Authors: Maalla Allam 
Published: May 2020

Abstract
DC converter station needs to consume a large amount of reactive power when transmitting active power. Insufficient or excessive reactive power will cause fluctuations in the AC voltage, which will affect the safety and stability of the entire system in severe cases. Simulation results verify the correctness, robustness, and superiority of the proposed active power allocation principle. This paper proposes a reactive power control strategy by fixing the position of the converter transformer tap and increasing the trigger angle/cut-off angle during the low-load operation of the DC transmission system.
Treatment of Refined oil depot wastewater
Authors: Wu Mengjie , Liu Zhen 
Published: May 2020

Abstract
In the treatment of oily wastewater, the water quality and quantity must be clarified. First, the physical form and chemical composition must be clarified, and then the drug can be treated according to the characteristics of various pollutants. The current treatment of wastewater from refined oil storage tanks is still dominated by the old three sets (sedimentation, flocculation, and biological methods). The current application research is mainly an optimization of the old three sets, such as the application of hydrocyclones, the preparation of new coagulants, the use of efficient air flotation devices and efficient microorganisms. However, the difficulty of wastewater treatment of refined oil depots is COD(Chemical Oxygen Demand). Due to the characteristics of oily wastewater, there are some limitations in biological methods. At present, the advanced oxidation method is not mature and the treatment cost is high, which restricts the advanced oxidation method to treat oily wastewater. This paper describes the source of oil products, the generation of oil-bearing wastewater and various processes of oil-bearing wastewater treatment. Finally, some ideas of advanced oxidation technology to remove COD from oil-bearing wastewater are put forward.
