INTEGRATED TREATMENT FACILITIES FOR REMEDIATION OF MOBILE CONTAMINANTS OF SOIL AND GROUNDWATER BY THE DIRECTION OF FLOWPATH, AND IT'S INSTALLATION METNOD

摘要

PURPOSE: A method for separating solids from water physically, and contaminants are removed by using microorganism to prevent from spreading of toxic materials in underwater. CONSTITUTION: An intercepting membrane(2) made of polyethylene or poly vinyl seat is installed to lead the flow of underwater. The underwater is treated in the trench(1), and flows through the intercepting membrane(2). The intercepting membrane can prevent from discharging the upper water and spreading of contaminants. A aeration tube(5) in shape of cylinder is installed at the bottom of the trench(4) to generate small bubbles, which is connected to a device for injecting air by a PVC pipe or cast iron pipe(6). The small bubbles are injected to volatilize volatile organic compounds and to let contaminants float on the surface of the water.
