APPARATUS FOR PURIFICATION NONPOINT POLLUTION SOURCE

摘要

PURPOSE: A nonpoint source pollutant processing structure is provided to secure the excellent nonpoint source pollutant processing efficiency after precipitating sludge inside an undercurrent tank. CONSTITUTION: A nonpoint source pollutant processing structure comprises the following: an undercurrent tank(10) including a precipitating space(10A) for discharging water polluted by nonpoint source pollutants after being precipitated; a scraper(20) installed inside the precipitating space to scrap sludge(2) inside the polluted water; a filtering unit(30) filtering the sludge; and a guide unit(40) guiding the sludge scraped by the scraper to the filtering unit.
