Abstract
A treatment method for chlorinated waste generated during production of TiC14 relates to a method for treating chlorinated waste. During discharging of the chlorinated waste, alkaline matters are coated on the surface of the chlorinated waste, dry alkaline matters are in contact with the chlorinated waste directly, and water-bearing alkaline matters are covered with the dry alkaline matters and then are in contact with the chlorinated waste; or the alkaline matters are covered with a steel plate or an iron plate with breather holes and then are in contact with the chlorinated waste; the space between metalware containing the chlorinated waste and the steel plate or the iron plate with the breather holes is sealed with wet clay; clay between the metalware containing the chlorinated waste and the steel plate or the iron plate with the breather holes is sealed; and the chlorinated waste is covered with the alkaline matters containing sodium series and lime series after being poured out of a container containing chlorinated waste salt. Through the treatment method, the long-standing problem that the environment is polluted during the discharging of waste salt and waste slag when TiC14 is prepared by the chloride process is solved, industrial waste such as calcium carbide sludge, magnesium slag and caustic sludge can be utilized, and the cost for preparing the chlorinated waste is lowered greatly.
