Abstract

The invention relates to waste water processing technology, and concretely relates to a method for processing titanium-containing organic matter-containing waste acid water from a polyolefin catalyst. The processing method is characterized in that a diffusion dialyzer is used for separating hydrochloric acid in the titanium-containing organic matter-containing waste acid water from the polyolefin catalyst to obtain hydrochloric acid and raffinate, titanium in the raffinate is conversed to a titanium dioxide solid for recovery by neutralizing, and finally a Fenton oxidation method is used for removing the organic matter in the raffinate which is used for filtering the titanium dioxide solid. The processing method fully realizes the resource recovery and reduces the risk of environment pollution.

Description

technical field [0001] The present invention relates to wastewater treatment technology, in particular to a treatment method for polyolefin catalyst-containing waste acid water containing titanium and organic matter, and more specifically relates to a method for recovering waste acid water containing titanium and organic matter produced during the preparation of polyolefin catalysts The method of processing. Background technique [0002] The polyolefin industry plays a pivotal role in the petrochemical industry. The products produced by the polyolefin industry are widely used in various fields and make a significant contribution to the national economy. Ziegler-Natta catalysts are the most widely used catalysts in the polyolefin industry. The Ziegler-Natta catalyst is prepared by mixing the titanium tetrachloride and the solid-phase carrier containing the magnesium compound for a period of time to obtain the high-activity Ziegler-Natta catalyst component. Then use a hydro...
