DEVICE FOR PURIFYING CONTAMINATED WASTE WATER

摘要

PURPOSE:To make it possible to remove rough particles suspended in contaminated waste water and further make it possible to capture fine particles and dissolving organic matter. CONSTITUTION:A waste plastic-piece layer 5 is interposed between a surface- attaching filter fibers 2 and a fiber net 3 disposed so as to be spaced apart a predetermined distance L from the layer 2 to constitute a cylindrical filter body 1. And contaminated waste water is passed through the body 1 from the inside to the outside thereof or from the outside to the inside to cause flocs generated in the waste water to attach to the fibers 2 and at the same time fine particles and dissolving organic matters are captured by means of algae generated on the layer 5.
