Based on investigating the water pollution status in municipal sewage canals，anewcanal reactor of coagulation is designed in simulated canalsinthe laboratory.Adding drug swith canal coagulant precipitation can improve municipal sewage efficiently.The experimental results show when the drugs are added section ally and the flow speedis controlled at42.2L/h，the removal rate of CODCris increased by 15%than the drug sweread dedat one time.The volume of sewage flocculantis nearly doubled
Key words： adding drugs section ally; canalcoagulation; sewage treatment
