摘要
以粉末活性炭(PAC)吸附去除微污染水库水中有机物为研究目标,考察投加量、吸附时间和pH值等因素对吸附效果的影响。结果表明:PAC投量30mg/L、吸附时间30分钟时,CODMn、UV254的去除率分别为39.8%和40.9%。调节原水pH值至弱酸性(pH=5.5),可以进一步提高粉末活性炭对CODMn、UV254的去除效果。根据生产实际情况,在水源本底pH值、粉末活性炭投量30mg/L和吸附时间30分钟条件下可以保证良好的出水水质。
This study investigated the organic matters in micro-polluted reservoir water removal influencing factors by activated carbon（PAC） dosage、adsorption time、pH value.The results indicated that：when the dosage of PAC was 30mg/L、adsorption time,the removal rate of CODMn、UV254 were 39.8%、40.9%,adjusted the pH value to 5.5 can promoted the removal rate.According to the treatment condition,it can ensure the water quality when PAC dosage was 30mg/L、adsorption time was 30 min and natural pH value by PAC adsorption process.
