APPARATUS FOR PURIFICATION NONPOINT POLLUTION SOURCE

摘要

PURPOSE: A nonpoint source pollutant process structure is provided to improve the nonpoint source pollutant processing efficiency by a precipitation method by removing precipitated sludge from an undercurrent tank. CONSTITUTION: A nonpoint source pollutant process structure comprises the following: an undercurrent tank(10) with a precipitation space(10A) to discharge water polluted by nonpoint source pollutants after being precipitated; a scraper(20) installed on the precipitation space to scrap sludge(2); a dust collecting chamber(50) with an opening(52) to be inserted with the sludge; and a guiding unit(40) for discharging the sludge scraped by the scrapper.
