ENVIRONMENT FRIENDLY CONSTRUCTED WETLAND SYSTEM FOR NONPOINT SOURCE POLLUTED WATER TREATMENT

摘要

PURPOSE: An environmentally-friendly artificial wetland system for treating non-point pollutants is provided to maximize the reduction of the non-point pollutants by purifying water introduced into wetlands and automatically draining the purified water. CONSTITUTION: An environmentally-friendly artificial wetland system includes an introducing part(10), a first discharging part(20), a wetland part(30), and a second discharging part(100). Water mixed with non-point pollutants when it rains is introduced through the introducing part. Purified water is discharged through the first discharging part. The wetland part secures a temporary storing space for water from the introducing part. A settling basin(31) is formed in the wetland part. A vegetation wetland(33) is generated in the wetland. A settling pond(35) is formed in the wetland to reduce the flux of water and eliminates soil from the water. A second discharging part is installed at the downstream part of the first discharging part and re-purifies the water from the first discharging part.
