Abstract
Ozone-Biological Activated Carbon (BAC/O3 ) process design was introduced in one first bulited water treatmen plant in Shifang Shichuan China.This paper discussed the experience and measures for O 3/BAC technology project.If the thecholgy for separa-ting oxygen from air was provided in project location , when the ozone consumption Q o3≤60 kgo3/h , purchase of liquid oxygen as the raw material would be more economical , when Qo3 >60 kgo3/h, adopting the separated oxygen from air whould be better .In pre-ozona-tion reactor, O3 charging quantity Q had more effect on the ozone oxidation effect than contact time T ,but if the raw water needed to kill alga, adviced T≥5 min;In post-ozonation reactor,usually divided into three phases , the best dosing ratio was 4∶3∶3,and the CT value (CT≥4 min・ mg/L) had representation meaning to kill “two bug”.The key indicators value of the Activated carbon adsorption and structure properties were introduced:iodine value was 900 mg・ g-1 , and JiaLan value was 150 mg・ g-1 , or specific surface area of 1000 1000 m 2・ g-1 , total pore volume was 0.6 cc・ g-1 , etc.; The light seal cover should be bulited above carbon filter , 500 mm sand was added under the carbon layer and design filter speed should be reduced to ensure safety operation and reduce the risk of mi -crobial penetration filter layer.关键词
