Description

        Water Pollution Permeation Style Purification System

 The present invention is a device for purifying before the non-point pollution flows into the river or the appeal, more specifically, the non-point pollution source that washes down the pollutants accumulated by the industrial activity of the artificial facility in rainwater during the early rainy weather. Non-Pollution Precipitation Separation Infiltration Purification System that can prevent water pollution of groundwater in advance and protect the aquatic plants of natural ecosystems from non-point pollutants by purifying pollutants before entering rivers and lakes. .

    In general, non-point source, which is one of the causes of unexpected ecosystem destruction due to the rapid development of industrial society, occupies 40-45% of aquatic source, and point source has more than 90% purification effect with current technology. As the purification technology is still in its infancy, non-point pollution purification technology is emerging as an essential condition for the prevention of water pollution.

    Due to the expansion of roads, industrial complexes, and cities, alternatives due to unexpected increase in nonpoint sources have not been sufficient, and they have not contributed significantly to the purification of water pollution. When non-point pollution is excellent in the early stages, pollutants scattered in cities, industrial complexes, and roadsides are temporarily introduced with rainwater, and are temporarily introduced into rivers and lakes, causing high levels of pollution and depletion of dissolved oxygen. By providing this, it became a serious environmental pollution, thereby increasing the water pollution load. The conventional technique developed to solve the problem of ecological destruction of non-point source has been discharged after sedimentation by temporarily forming a pool in the drainage of roadside, and then discharged after sedimentation. There is a problem that the function of the rainwater is not distinguished by the latter rainwater, and the function is lost due to the continuous inflow of the rainwater. In addition, the vegetation type purification device via the gravel layer also caused a problem that the pores of the gravel layer were closed due to the difficulty of continuous soil management and aftercare, thereby preventing long-term function.

     The present invention forms a filter permeation part after the first and second stage sedimentation of the rainwater inlet, thereby preventing the functional degradation of the filter permeation part by the sediment in advance, and the filter permeation part is the filter layer and the soil permeation layer at the bottom of the soil permeation tube. To increase the decomposition of organic matter by planting plants at the top, and to facilitate the discharge of filtered water by passing through the outflow pipe when the penetration power of groundwater is reduced, the purpose of solving the problems of long-term use have.

     The present invention is formed in the rainwater inlet and the filter penetrant after the first and second precipitation separation, the first and second hoppers are disposed in the first and second sedimentation separation is collected through a certain amount of collecting holes when a certain amount is collected In particular, the rectifier placed in the secondary sedimentation chamber improves the ability to purify the untreated pollution in the primary sedimentation separation chamber by vortexing, and the filtration permeate is discharged through the outflow hole of the soil infiltration pipe. The treated water is absorbed by the filtration layer and the upper part is decomposed by soil microorganisms while supplying the planted plant as a nutrient source of organic matter, and the lower part is infiltrated into the groundwater by the soil penetrating layer or discharged along the outlet pipe.

    The non-point pollution sedimentation separation type purifying apparatus of the present invention collects in the first hopper by sedimentation and separation by rainwater inlet having a screen for blocking large foreign matters, and solidified organic matter and micro-earth gravitational inflow, suspended matter and fallen leaves, etc. The primary sedimentation separation chamber having separate storage and purification means for separating the sediment floating up due to the specific gravity difference, and the rectifier having a cylindrical source of residual pollutant which has been untreated in the primary sedimentation separation chamber are formed through the secondary hopper. Secondary sedimentation chamber, where sediment is collected, and the treated water discharged through the outflow hole of the soil infiltration pipe are absorbed by the filtration layer, and the upper part is supplied to planted plants as a nutrient source of organic matter or decomposed and removed by soil microorganisms. The water is characterized by a filter permeate that seeps into the groundwater by the lower soil penetrating layer or discharges along the outlet pipe.
