Start-up of a Pilot Hybrid Process to Treat Micro-polluted Water of the Main Canal in Shangyu City
摘要
Abstract
Aiming at the water quality of the micro-polluted water of the main canal in Shangyu city, a pilot-scale study was conducted adopting a hybrid process by combination of coagulating sedimentation, biological aerated filter packed with zeolites (ZBAF) and filter packed with granular activated carbon (GAC) . The results showed that when ZBAF was operated for 20 days at the conditions of temperature as 25℃ -29℃, the gas to liquid ratio as 1:2 and filtering velocity as 2. 5 m/h, the biofilm was formed, with which at filtering velocity of 5 m/h the removal rate of turbidity, NH3-N, UV254 and CODMn of the hybrid process were 99%, 85%, 70%and 75%. respectively. It obtained a good quality of effluent with turbidity, NH3-N and CODMn being stably lower than 0. 5 NTU, 0. 1 mg/L and 1.5 mg/L respectively.关键词
