ENERGY SELF - SUFFICIENT AND NON-POINT SOURCE REMOVAL APPARATUS FOR THE FIRST-FLUSH STORMWATER

摘要

PURPOSE: An energy self-sufficient apparatus for removing nonpoint pollutants from initial rainwater is provided to prevent pollutants from being deposited or attached on an inclined plate. CONSTITUTION: An energy self-sufficient apparatus for removing nonpoint pollutants from initial rainwater comprises an outer case(10), a cyclone case(20), a cylindrical inclined plate(30), a self-supporting swirl flow generation unit(40), an overflow channel(53), a microfiltration filter(56), and a discharge channel(58). The outer case has an inflow channel(13). The cyclone case is installed inside the outer case and has multiple through holes(23). The cylindrical inclined plate is installed inside the outer case to surround the cyclone case. The self-supporting swirl flow generation unit generates a swirl flow in the inner bottom of the cyclone case. The overflow channel is installed on the outer side of the top end of the cyclone case, and rainwater overflowing from the cyclone case flows into the overflow channel. The microfiltration filter filters pollutants from the rainwater flowing from the cyclone case to the overflow channel. The discharge channel is connected to the overflow channel and discharges the rainwater, which does not have the pollutants, to the outside of the outer case.
