Abstract

In order to effectively isolate the marine wastes with an effluent standard, the pretreatment process is required to isolate solid materials from the liquid- solid mixed wastes. The more effective the pretreatment becomes. the more processing capacity of posttreatment will be improved and process facilities will be downsized. In this paper. we suggested the vibrating revers-slant screen, investigated the optimal vibration frequency and vibrator installation angle for the separation of the liquid' solid mix ed waste s. Several experiments for separation efficiency were conducted under the condition of various vibration frequency(35 ~ 60Hz, 5Hz interval ) and vibrator angle(0°, 30°, 45°, 90°) considering the crack of screen The screen inclination angle is set up the gradient as 3°~5° through the preliminary experiments. Also, we made two types of screen(respectively rectangle and square screen). The separation device has shown the optimum efficiency at vibrator angle O° and vibration frequency 60Hz and bas no relation with the shape of screen. And the proposed technology is verified by comparing with quantity of suspended solids before and after filtration.
