NON-POINT POLLUTION TREATMENT DITCH

摘要

PURPOSE: A nonpoint pollution treatment channel is provided to reduce construction and maintenance costs because pressing facilities, such as a pump, are not required. CONSTITUTION: A nonpoint pollution treatment channel is comprised as follows. A sediment channel(10) and a filtration channel(30) connected to the sediment channel are formed in the inlet of the channel. A screen(20) is installed between the sediment channel and the filtration channel. Bags(40) filled with fine granule filter media and porous loading plates(50) having granular filter media(59) are installed on the bottom and top of the filtration channel to simultaneously treat nonpoint pollutants in the sediment channel and the filtration channel.
