摘要

The performance of an electrocoagulation (EC) process by adding titanium plates (electrooxidation,EO) was studied for the treatment of textile wastewater using combined electrical connections in asingle reactor. Aluminum (and iron) and Titanium (Ti) electrodes were fixed in a bipolar (Bp), andmonopolar (Mp) structure in the same electrolytic cell. The performance of the reactor wascharacterized in terms of electrolysis time (RT), current intensity (I), pH, chemical support, inter- electrode distance (IED), and stirring speed (Mrpm). Furthermore, energy and electrode consumption,sludge compaction, operating expenses as well as comparison with the conventional EC process wasalso examined. The most suitable EC-EO performance was achieved by using Mp Ti-Bp Al plates.Preliminary results showed the following optimal operating conditions: I=0.6 A, pH=6, IED=1cm andMrpm=500 rpm. The implementation of these parameters on textile wastewater revealed a relativelyhigh removal efficiency of COD (93.5%), TSS (97%), color (97.5%), BOD5 (90%), TDS (89%),turbidity (96%), phenols (99%) and phosphate (97%). The overall operating cost for the process was3 1.69 US$/m . This value was calculated based on the electrode and energy consumption, chemicals,and sludge disposal.
