在自来水处理过程中,水质好坏在于澄清与消毒,而澄清的关键又在于连续不断地投加适量的混凝剂。目前,很多水厂用聚合氯化铝或硫酸铝溶液作为混凝剂,在生产过程中经常发生输送矾液的管道被沉渣堵塞,造成矾液中断或减少,而值班人员不易及时发现,致使影响水质。针对这个问题,我们试制了一种简单的断矾报警器,当投加的矾液中断或矾液减少到预定量以下时,报警器会发出警报,提醒值班人员及时处理。我们在南昌市自来水公司朝阳水厂(日产20万吨)装置试用,效果很好,每套装置材料费约25元。
In the tap water treatment process, the water quality is good or bad, which is clarification and disinfection. The key to clarification is to continuously add appropriate amount of coagulant. At present, many water plants use polyaluminum chloride or aluminum sulfate solution as a coagulant. In the production process, the pipeline for transporting helium liquid is often blocked by sediments, causing turbulence to be interrupted or reduced, and the on-duty personnel are not easy to find in time, resulting in an impact. Water quality. In response to this problem, we have trial-produced a simple break alarm. When the added liquid is interrupted or the liquid is reduced below a predetermined amount, the alarm will sound an alarm to alert the on-duty personnel to deal with it in time. We tried the installation of the Chaoyang Water Plant (200,000 tons per day) at the Nanchang Water Supply Company, and the results were very good. The cost for each set of equipment was about 25 yuan.
