Korean Journal Limnol. In order to prevent water pollution caused by natural contaminants, fluidity is given to the body. In order to improve water quality, Biostone filter media However, as we know it, the biofilm formed in the filter medium adheres to solids, which eventually inhibits the growth of the biofilm. At the same time, the biofilm and the solids can cause deterioration of the water quality have.
The Korean Society of Soil Science and Zoology. Vol. 44 No. 3 425-433 (2011) is a study to treat livestock wastewater with pollution degree several hundred times that of domestic wastewater by natural purification method using artificial wetland. The activated sludge tank was treated with aerobic treatment or anaerobic treatment by the third treatment using the filter material which was used in the livestock wastewater treatment plant and the artificial wetland planted with aquatic plants The above-mentioned process is a result of an experiment with an intention to be applied as an auxiliary water treatment technique to meet the discharge water quality standard of livestock wastewater by a pretreatment process of an animal wastewater treatment facility, and the above- It is clear that the efficiency of removal of nitrogen and phosphorous (TP) through the plant is enhanced, but the characteristics of the incoming livestock wastewater are significantly different according to the livestock farmers However, in the experiment, it was found that the result of linking activated sludge tank and constructed wetland with livestock wastewater treatment plant is relatively higher than the result of treatment with aquatic plant filtration tank and artificial wetland by pretreatment with livestock wastewater treatment plant COD, SS, TN, and TP treatments. Especially, treatment effects of TN and TP were very high, so that it was possible to treat high concentration livestock wastewater stably.
J. Korean Soc. Hazard Mitig. Vol. 2 (Apr. 2014) pp. 327-336 is a study on water pollution in swimming river and onsen river in Busan area. As a result of the study, it was found that the main source of nonpoint source was the inflow from the overflow from the sewage submerged pipe during rainfall. To solve this water pollution problem, The SWMM was used to select the priority management watershed and to propose the installation method of the non-point pollution deduction facility and to verify its efficiency. Especially, the low detection effect of BOD and TP which directly affect the river pollution was shown.
J. Kor. Soc. Environ. Eng. 36 (12), 813-820, 2014 are studies on water pollution caused by nonpoint pollution sources in Daedongcheon, Yuechuncheon, and Gapcheon in Daejeon Metropolitan City. Generally, water quality in the downstream of river is poor due to sewage treatment plant effluent (TP) in the upstream area of the stream, it is necessary to maintain the maintenance of the sub - pipeline.
J. Kor. Soc. Environ. Eng. 37 (2), 126-135, 2015 is a study on small rivers in urban areas. Due to the increase in the impervious area, which is characteristic of urban areas, and the installation of the bridges, the rate of non-point pollutants and rainwater run- And it is found that if the rain does not flow, the serious problem of the river environment is caused by the decrease of the flow rate. In order to effectively manage the initial rainfall storage and treatment facilities developed to reduce these problems, SWMM urban watershed model was applied to a large amount of rainfall over 7 mm, which was dominated by the flow rate rather than the concentration of pollutants In this case, the inflow rainfall exceeding the treatment capacity should be discharged directly to the river without passing through the initial stormwater treatment facility. On the contrary, when a small amount of rainfall of 7 mm or less, the inflow rainfall is preferably passed through the initial rainfall treatment facility Respectively.
J. Kor. Spatial Infor. SOC. Vol.22, No.2: 45-52, Apr. 2014 is an application program of spatial information for the development of river pollution management system. For more accurate framework, we applied GPS and GIS to establish a quantitative analysis and management plan of river pollution. Through the analysis, It is possible to construct a pollution control system.
Despite the implementation of the sewer pipe installation project and the sewage treatment plant installation project, which was promoted by the Ministry of Environment as the main axis for the past ten years, the pollution caused by sewage and pollution from non-point sources polluted the river. .
In order to solve the above-mentioned problems, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a water purification plant for preventing the filtration by the solid matter contained in the initial rainwater including the domestic sewage, A filtration device capable of removing solids continuously introduced into a pretreatment device of an aquatic plant filtration device is required in order to prevent the pores of the planting soil from being clogged with solids and failing to exhibit a pure function, It is practically impossible to arrange the filtration device so as to prevent the filtration surface of the filtration device from being clogged by itself, so that the filtration surface residues (i.e., solid matter) generated during the cleaning are transferred to one side of the filtration device To be separated from the water system to prevent contamination of the water quality, A device that can block the inlet duct in advance is necessary to prevent the damage from occurring in Sanaa Saturday, impurities are introduced into the water treatment system installed in Wuxi.
