Abstract
Under the influence of the information age, modern architecture tends to develop in a diversified direction. Pop art, which was born in the middle of the 20th century, is the product of a specific historical period. the popular, grotesque and playful art form shown by pop art has a far-reaching impact on the development of modern architectural forms. to a certain extent, pop art breaks the boundary between art and life in a relaxed and playful popular way. With the increasingly monotonous style of modernist architecture, the appearance of the city has become increasingly rigid and monotonous. Pop architecture has entered the public line of sight with its popular and witty characteristics, injecting new vitality into modern architecture. However, some elements and design techniques of pop architecture can still be found in today‘s architecture and have a far-reaching impact. Through the analysis of the emergence, development and characteristics of pop art, combined with the relevant cases of modern pop architecture at home and abroad, from the point of view of collage integration, figurative architecture and mechanical reproduction, this paper expounds the application of pop art in modern architectural form design, and provides a new way for reference in architectural form design.

Abstract
Research on genetic biodiversity can essentially reveals the origin of species diversity, variation and evolution. The koi carp (Cyprinus carpio L) is well known for its vigorous body and gorgeous colour. However, there is still lack of knowledge for Koi carp genetic biodiversity. In this paper, the genetic biodivesity of 15 microsatellite loci in breeding population of red and white Koi carp was analyzed. Our results showed that 56 alleles were detected in the population by 15 microsatellite primers, and the number of allele at each locus ranged from 3 to 5, with an average of 3.73. The average observed heterozygosity was 0.6963 while the average expected heterozygosity was 0.6208. The average polymorphism information content (PIC) was 0.557. Out of 15 detected loci, 11 loci were in high polymorphism degree (PIC≥0.5), 4 locus was in medium polymorphism degree. The average Fis is -0.1251. The results indicated rich polymorphism information content and large genetic diversity in the population. This breeding population of the red and white Koi carp had a large selection potential and could be adopted as a base population for further selection.
Research on Activating Persulfate by Co-based Multicomponent Canalysts
Authors: Liu Qiang 
Published: June 2020

Abstract
Persulfate (PS) is a hydrogen peroxide (H2O2) derivative, which can be catalyzed to produce sulfate radical. It can be activated in the following three ways: energy excitation, alkali activation and transition metal activation. Sulfate radical oxidation is an important advanced oxidation technology for wastewater treatment and Advanced oxidation method is the main method for the treatment of refractory organic wastewater, mainly through the generation of hydroxyl radical (•OH) or sulfate radical (SO4
−•) and other free radicals to initiate a series of chain reactions. Co2+ activated persulfate (PMS) produces SO4
−• and Co3+ showing strong oxidation capacity. The preparation of catalysts prepared by “transition-metal, rare-earth-metal and noble-metal” can activate persulfate and produce SO4
−•, which can effectively degrade dyeing waste-water.

Authors: Liao Wenchao , Xu Su , Chen Wenwen , Liao Shuyi 
Published: June 2020

Abstract
Antibiotic wastewater may generate more toxic by-products in the degradation process. It is of great significance to study the toxicity changes of the antibiotic intermediates for ecological safety of water environment. The microwave-enhanced photolysis process was set up and applied to the antibiotic tetracycline degradation. The luminescence inhibition rate of the luminescent bacteria was used as the evaluation index to investigate the acute toxicity changes of tetracycline intermediates. The toxicity changes with the degradation time and the effects of common water quality factors such as NO3
−, Cu2+ and humic acid on the acute toxicity of intermediates were studied. The results showed that nine intermediate products formed in the microwave-enhanced photolysis process. The acute toxicity of intermediates was generally reduced compared with tetracycline itself, but the luminescence inhibition rate of intermediates fluctuated with time. The luminescence inhibition rate of intermediates after 4 min of reaction was the highest, which meant the acute toxicity of intermediate products at 4 min was the largest. The presence of NO3
− (high concentration) and Cu2+ increased the acute toxicity of tetracycline intermediates, but the presence of humic acid could help reduce the acute toxicity of tetracycline degradation intermediates. This study provided theoretical basis and data reference for the practical application and ecological risk assessment of microwave-enhanced photolysis degradation of tetracycline.
Study on the Performance of Ru Catalyst Based on the Treatment of Refractory Biodegrading Organic Wastewater
Authors: Zhang Yongxun , Zhang Yongli 
Published: June 2020

Abstract
Supported metal catalysts are widely used in the field of refractory biodegrading wastewater treatment because of their unique catalytic performance. The non-homogeneous CWAO process is used to treat the refractory biodegrading ceramic printing wastewater. The pH, decolorization rate and COD removal rate of water sample are used as the evaluation indexes of catalyst activity, and the metal dissolution concentration is used as the evaluation indexes of catalyst stability. Then the performance of the catalyst is evaluated comprehensively. As the reaction time goes on, decolorization rates of water samples with different groups of Ru catalyst increase. The decolorization rate of CWAO method for wastewater treatment reaches 80.4%, 78.3% and 76.7% respectively, indicating that the activity and stability of this catalyst are good. The overall trend of pH value of water sample from the first time, the second time and the third time is slightly higher, because generally printing and dyeing wastewater is alkaline, the higher the pH value of water sample indicates the lower the water sample treatment efficiency, that is, the catalyst catalytic efficiency has declined. From the first, second and third use sequence, the COD of water samples are all over 74.0%, and the COD removal rate is gradually reduced. The results show that the Ru-Fe-Co-Ce/FSC (ratio 2:0.5:0.5:3) catalyst has good catalytic activity and stability.
Research on the Stability of Pd-Catalysts Based on the Treatment of Refractory Biodegrading Organic Wastewater
Authors: Zhang Yongli 
Published: June 2020

Abstract
The non-homogeneous CWAO method was used to treat refractory biodegrading organic wastewater. The re-usability of Pd-catalyst was investigated. The pH and decolorization rate of waste-waters were used as evaluation indexes. The results showed that the pH of waste-water did not change obviously in the first, second and third use of catalyst. The absorbance difference between the second and third use of catalyst waste-waters is approximately equal, but they are both larger than that of the first use and smaller than that of blank waste-waters. The decolorization rate of the first use is obviously higher than that of the second and third use, and the second use is higher than that of the third use, but the difference is not great, which shows that the catalyst has good re-usability. Compared with the last application of catalyst, the decolorization rate of waste-water decreased 3.8% and 1.6% respectively in the second and third application. Pd-Fe-Co-Ce/FSC (ratio 1:1:1:3) catalyst has good catalytic stability.

Published: June 2020

Abstract
Organic waste-water is treated by catalytic wet oxidation method (CWAO). The catalysts are prepared by the same amount of impregnation method. Fe and Co are used as active components of the catalyst, and Ce is used as the catalytic assistant, and the precious metal Pd is added to prepare a multi-component composite catalysts. When the Pd-based catalyst is added to the waste-water, the pH decreases and then increases. The process of organic matter degradation is first converted to small molecule organic acids, the pH is reduced, and then the small molecule organic acids are gradually decomposed. In the proportion of Pd-catalyst, as the Pd content in the catalyst increases, the treatment effect of the waste-water is enhanced; Effect of different ratios on the stability of Pd-Fe-Co-Ce/FSC catalysts showed that, CODCr removal rate increased from 65.7% to 84.7%, and decolorization rate increased from 72.5% to 97.2%. The average concentration of Pd3+, Fe3+, Co2+ and Ce3+ dissolved is 0.0015, 2.2519, 0.2281 and 0.2300, respectively. The Pd-catalyst Pd-Fe-Co-Ce/FSC with metal ion ratio Pd-Fe-Co-Ce=1:1:1:3 has the highest activity in waste-water treatment, and CODCr removal rates and decolorization rates reach 88.7% and 97.9%, respectively.

Authors: Zhang Yongxun 
Published: June 2020

Abstract
Based on the catalyst Pd-Fe-Co-Ce/FSC(ratio 1:1:1:3), a catalytic wet oxidation method was used to treat organic waste-water that is difficult to biodegrade. The calcination temperature of the catalyst was set to 550 °C, and the calcination time was set to 1 h, 3 h, 5 h, 7 h in order. From the analysis, it is found that the effluent pH first decreases and then increases. With the extension of the reaction time, the absorbance of the treated waste-water decreases, and the decolorization rate increases. With the extension of the reaction time, the COD of the treated water sample decreased and the COD removal rate increased. For catalysts No.1, No.2, No.3 and No.4, the COD of wastewater was 10851, 768, 1149 and 1238 mg/L at 120 min of catalytic wet oxidation of wastewater, and the corresponding COD removal rates was 84.1%, 88.7%, 83.1% and 81.8%, respectively. The experimental results showed that the catalyst prepared by calcining for 3 h had a COD removal rate and a decolorization rate of 88.7% and 97.9%, respectively, and the metal dissolution solubility of the treated water was relatively low. 3 h is a suitable catalyst’s calcination time.
