Abstract
Traditional freshwater aquaculture can easily cause serious environmental problems and waste of water resources. Thus, ecological bioremediation techniques for freshwater pond environments are more attractive. In this study, a set of compound wetland ecological system with ecological ditch, constructed wetland and multi-functional ecological pond was constructed, and its purification effect was also evaluated. Our results showed that the compound wetland ecosystem has high removal efficiency for aquaculture wastewater. The concentration of total nitrogen, ammonia nitrogen, Nitrite Nitrogen, total phosphorus, and chlorophyll-a in each treatment unit gradually decreased after the system was stabilized. The annual average removal rates of TN, NH4
+-N, NO2
−-N, TP and Chl-a can reach 73.03%, 74.27%, 91.89%, 64.29% and 83.02%. We found ammonia nitrogen concentration was significantly biodegraded (p <0.05) by the ecological ditch, as well as constructed wetland and multi-functional ecological purification pond had obvious removal effect on TN, TP, NH4
+-N, NO2
−-N, and Chl-a (p <0.05). Moreover, the concentrations of pollutants after purification were lower than the standard value of fishery aquaculture water quality in China, and the purified water was recycled to fish ponds for reuse. Therefore, the compound wetland ecosystem can be adopted by the water shortage area to develop water-saving fisheries in the future.

Published: July 2020

Abstract
During the treatment of penicillin wastewater, facultative and aerobic bacteria in intermittent aeration can effectively degrade the organic matter in the wastewater without physical and chemical pretreatment of SO4
2- and DTAB. When the highest COD concentration of the influent is 12 000 mg/L, the load is 8 kgCOD/(m3·d), and the maximum impact load is 13 kg COD/(m3·d), COD removal rate can reach over 87%. The foam produced by DTAB in penicillin wastewater will not affect the normal operation of the SBR treatment plant. The foam can disappear in the aeration process, and eventually the DTAB can achieve more than 97% removal rate. Therefore, sequencing batch reactor is an ideal way to treat penicillin wastewater.

Abstract
With the rapid development of the social economy in China, although people’s living standards have improved, the problem of environmental pollution is becoming more and more serious, especially the pollution of water resources. A large amount of sewage is often discharged in life and production, which will pollute the underground, lakes, rivers and other water resources, and then affect people’s normal life and life safety. However, the efficiency of the sewage treatment system at this stage is relatively low, which is difficult to meet the needs of today’s social development. In this case, to improve the effect of sewage treatment, it is necessary to use electrical control automation and make scientific and rational use of the advantages of electrical control automation to fundamentally improve the efficiency of sewage treatment. This paper focuses on the electrical control automation of the sewage treatment system and shows some new intelligent control technologies.

Abstract
In order to improve the photo-degradation efficiency of waste gas and the utilization rate of ultraviolet lamp, numerical simulation software was used to simulate the wind speed field in ultraviolet equipment. The simulation of uniform and dislocation arrangement of ultraviolet lamp in ultraviolet equipment, taper of variable diameter of equipment, transverse flow and cis flow of ultraviolet equipment is presented. The results show that the gas flow in the equipment is more uniform than that in the ultraviolet lamp. The reducing taper of ultraviolet equipment becomes smaller, and the gas retention area gradually becomes smaller. When the reducing taper is reduced to 30°, it is most suitable. The wind speed field in the downstream ultraviolet equipment is more uniform than that in the horizontal flow type, and the ultraviolet utilization rate is higher. In addition, the tubular downstream ultraviolet equipment can not only ensure the utilization rate of ultraviolet lamp, but also improve the degradation effect of organic waste gas.

Influence of Oil Pollution on Soil Water and Fertilizer Coordination Ability
Authors: Yang Wei 
Published: July 2020

Abstract
The soil guarantees the normal growth and development of the plant by coordinating the nutrition and environmental conditions such as water, fertilizer, gas, and heat. However, once the soil is polluted by oil, its own ability to coordinate water and fertilizer will inevitably be affected, thereby affecting plant growth. Therefore, it is proved that the impact of oil pollution on the coordination ability of soil water and fertilizer is the basic prerequisite for the reuse and restoration of contaminated soil. This article can provide basic guidance for the use and remediation of contaminated soil.
