Abstract
A method for preparing un-hardened ceramic micro-electrolysis fillers by industrial solid wastes comprises: (1) Scrap iron, lignin, red mud and clay was completely mixed as mass ratio (4-5):(2-3):(1-3):3 and then made into pellets; (2) The dried pellets were sintered without oxygen. The production could be used in wastewater treatment, which could not only increase biodegradability but also decrease CODCr and toxicity in a short time.
