摘要:
模拟实际原水输水管道,构建了长距离管道生物化学反应器,研究了粉末活性炭对管道中污染物的强化去除作用.结果表明:有机污染物的去除效率随粉末活性炭投加量的增加而提高;当反应时间为8 h,粉末活性炭投加量为17 mg/L时,CODMn, TOC, DOC和UV254的去除率分别达到51.2%, 45.9%, 56.5%和70.6%,分别比未加粉末活性炭时提高了34.5%, 34.8%, 42.1%和57.0%;而粉末活性炭对藻类和氨氮的去除效果不明显.同时,微囊藻毒素-LR、六氯苯和邻苯二甲酸酯类物质的去除率分别达到61.1%, 42.1%和49.0%,提高了49.3%, 31.4%和31.2%.粉末活性炭能够有效抑制消毒副产物的生成.因此,针对污染较严重的水源水或遇到突发污染事故时,向管道内投加粉末活性炭能有效促进污染物的去除.
Abstract:
A long-distance pipeline biochemical reactor was constructed to simulate raw water delivery pipelines. Effects of powder activated carbon(PAC)on the purification efficiency of the reactor were studied. The results show that the removal efficiency of organic pollutants is significantly strengthened with the increase of the dosage of PAC. When the reaction time is 8 h and the PAC dosage is 17 mg/L, the removal rates of chemical oxygen demand(CODMn), total organic carbon(TOC), dissolved organic carbon(DOC)and UV254(ultraviolet absorbance at 254 nm)are 51.2%, 45.9%, 56.5% and 70.6%, which are increased by 34.5%, 34.8%, 42.1% and 57.0%, respectively, compared with no addition of PAC. However, the concentrations of algae and NH+4-N are not clearly reduced. The removal rates of microcystin-LR(MC-LR), hexachlorobenzen(HCB)and phthalate esters(PAEs)are 61.1%, 42.1% and 49.0%, which are increased by 49.3%, 31.4% and 31.2%. In addition, PAC can effectively reduce the generation of disinfection by-products. Thus, PAC can improve the removal of organic pollutants in long-distance water delivery pipelines when water pollution is serious or in emergency.
