NON-POINT SOURCE CONTAMINANT PURIFICATION SYSTEM OF COMBINING OIL-WATER SEPARATION WITH UPWARD MOVEMENT FILTRATION BY USING FILTER MEDIUM MOVABLE FILTER AND NON-POINT SOURCE CONTAMINANT PURIFICATION THEREBY

摘要

PURPOSE: In the most of the floatability nonpoint pollutant of the oil lamp is the separation of water from oil settling tank, it separates in initial from the superiority. Inflow to the clarification plant in which all kinds of the filters are installed conspicuously shrinks. CONSTITUTION: The nonpoint pollutant processing unit(2) of the Upward filtration complex method and separation of water from oil. In order to sift out the gasoline and the floatability adulteration quality included in the initial rain inflow water the separation of water from oil is included. With the first process bath in which the precipitate of the precipitability nonpoint pollutant is included.
