Condition Optimization and Operation Analysis of Pure MBBR Process for a Large Scale Water Purification Plant
摘要
Abstract
The original horizontal sedimentation tank end of large water purification plant in Guangdong Province has transformed into pure MBBR progress to improve the removal efficiency of ammonia nitrogen for micro-polluted raw river water treatment.After reconstruction,in stable operation period,the average effluent concentrations of CODMn,BOD5,ammonia nitrogen,TP and SS are 19,2.7,0.47,0.10 mg/L and 8 mg/L,respectively,with the average removal efficiency of 24.11%,35.03%,85.17%,56.30%and 57.15%,respectively,meeting the class Ⅲ water quality standard of Environmental Quality Standards for Surface Water(GB 3838-2002).A pilot study investigates the effects of operating conditions such as water temperature,air-water ratio,hydraulic retention time and filler filling ratio on the nitrification performance of pure MBBR process.Results show that the water temperature is 25℃,air-water ratio is 1.50 ∶ 1,hydraulic retention time is 54 min and filling ratio of suspended filler is 40%,under the best operation condition,the average removal efficiency of ammonia nitrogen reaches 97.79%.The paper also summarizes the test and operation experience of pure MBBR progress applied in large WTP,so as to provide experiment for the similar engineering projects in the future.关键词
