摘要
再生水厂的消毒工艺通常都是几种消毒方式的联合使用,为了充分发挥各个消毒单元的优势,使得在出水水质达标的情况下,消毒的负面影响最小、成本最低,针对某再生水厂的实际情况,开展了消毒工艺优化生产性试验研究,最终确定了各消毒剂的最优投加量。优化后,消毒剂的投加量降低了,而出水的总大肠菌群数和粪大肠菌群数并没有增加,并且每年可节省消毒成本为87.6万元,具有良好的经济效益和环境效益。
Several disinfection methods are usually used together in a reclaimed water disinfection process. In order to make full use of the advantage of each disinfection unit, the disinfection process of a reclaimed water treatment plant was optimized to ensure the effluent quality to meet the discharge standard with the minimal negative impact of disinfection and the lowest cost. The optimal dosages of various disin- fectants were determined. After the optimization, the disinfectant dosage was reduced while the total coliform count and the fecal coliform count in the effluent did not increase. The annual saving of disinfection cost was 0.876 million yuan, showing good economic and environmental benefits.
