Distribution Characteristics and Environmental Responses of Benthic Diatoms in Reservoirs in Headstream Area of Le'an River
Published 2022-01-01“…This study aims to investigate the community distribution characteristics of the benthic diatom species in the reservoirs in the headstream area of the Le'an River and the response relationships of those species with environmental factors.For this purpose,the composition and water physicochemical parameters of benthic diatom communities in Datangwu reservoir,Qinghua reservoir,and Shijing reservoir in Wuyuan County were measured in the winter of 2020.Pearson correlation analysis and redundancy analysis were performed to explore the spatial distribution characteristics of benthic diatoms and the abovementioned response relationships.The results show that a total of 73 species,belonging to 24 genera,of diatoms are detected from 11 sampling sites.Specifically,the abundance of the dominant species Cyclotella stelligera is 21.91%,and the Melosira,Cocconeis,and Achnanthes genera are widely distributed.The following observations can be made from the analysis of the distribution characteristics and environmental responses of the diatoms:The relationship between Melosira varians and water eutrophication level is significant;a marked positive correlation is observed between Cyclotella stelligera and COD<sub>Mn</sub>;Cymbella perpusilla and total phosphorus (TP) are negatively correlated.NH<sup>+</sup><sub>4</sub>-N and NO<sup>-</sup><sub>3</sub>-N are significant factors affecting the differences among diatom genera and species,altogether explaining 43.1% of the diatom information.A preliminary determination is made that the structure of the benthic diatom communities in the reservoirs in the headstream area of the Le'an River responds simultaneously to NH<sup>+</sup><sub>4</sub>-N,NO<sup>-</sup><sub>3</sub>-N,COD<sub>Mn</sub>,TP,and other parameters.…”

Research for Impact of Discharge on Continuously Treating Micro-polluted Water by Electrocoagulation
Published 2021-01-01“…Purification and utilization of micro-polluted water like rainwater will be an effective way to solve the problems of water shortage.As a low-cost,high-efficiency wastewater treatment technology with a wide range of prospects,electrocoagulation has been proved to have a significant effect in treatment of heavily polluted wastewater such as industrial wastewater and domestic sewage.However,there are currently few studies on purification of micro-polluted water by electrocoagulation.Compared with batch treatment,continuous electrochemical treatment is simpler and faster,and large in treatment capacity,without human intervention.This paper discusses the impact of discharge on the continuous treatment results by electrocoagulation based on the experimental investigation of electrocoagulation test of river water.The results show that the discharge has a significant impact on the continuous treatment of micro-polluted water by electrocoagulation.There is a suitable discharge value,but the law is not obvious.Under the condition of the current density of 14.79 A/m<sup>2</sup>,and the plate distance of 1.5 cm,the discharge is about 2.0 mL/s,and after 3-hours reaction,the chroma removal rate of polluted water is 48.88%,the turbidity removal rate is 73.17%,the removal rate of suspended solids is 58.06%,the removal rate of COD is 35.00%,and the removal rate of total phosphorus is 51.22%.Furthermore,the pH of treated water rises slightly,and its conductivity decreases a little.Therefore,it is feasible to continuously purify micro-polluted water by electrocoagulation.…”

Treatment Project Design for Weakly Saline Water Bodies in Desert Parks and Practice
Published 2022-01-01“…The eutrophication control of a saline park water body in the Inner Mongolia Plateau is conducted by constructing a complete aquatic ecosystem.Acid-alkali adjustment of this water body is carried out to build aquatic plant and animal communities in the lake body,and functional bacterial agents are also supplemented to build and restore microbial communities.Moreover,the stable development of the ecosystem is guaranteed by on-site maintenance measures.The project effect shows that the aquatic ecosystem remains stable after its successful construction,with a clear water body that offers a favorable pollutant removal effect and main water quality indexes significantly better than those before treatment.Specifically,the pH of the water body decreases from 9.09 to 8.75,and the turbidity is lowered from 20.5 NTU to 4.0 NTU.Regarding transparency,it reaches more than 1.5 m at the deepest part of the water body,or even a clear bottom is achieved.The total phosphorus concentration decreases from 0.19 mg/L to 0.03 mg/L,and the COD<sub>Cr</sub> concentration is reduced from 109.5 mg/L to 17.0 mg/L.In addition,aquatic animal biomass and the number of species of aquatic animals increase significantly.The above results indicate that the water quality improvement target is achieved.The aquatic ecosystem after treatment with maintenance measures can resist external disturbance to a certain extent,and the implementation of this project can provide a reference for the treatment of saline lakes in plateau areas.…”
