一净水构筑物概况我公司第一水厂原水力循环澄清池于1997年5月改造建成网格反应斜管沉淀池。改造后的池子,净水能力由平均10000m~3/d,提高到20000m~3/d。沉淀池出水浊度保持在8度以下。该池的排污全靠人工的经验进行周期性排放,由于进水量和原水浊度的不断变化,导致排污出现超前或滞后。超前排污浪费原水;滞后排污影响沉淀池出水水质。由于每天需几次开关排污闸阀,每年至少更换一次排污阀,既增大了工人的劳动强度,又增加了维修费用。 Overview of a water purification structure The first water works of our company, the original hydraulic recycling clarifier pool, was rebuilt in May 1997 to build a grid reaction settling tank. After the transformation of the pool, water purification capacity by an average of 10000m ~ 3 / d, increased to 20000m ~ 3 / d. Sedimentation tank effluent turbidity remained below 8 degrees. The discharge of the pool is entirely based on manual experience of periodic discharge, due to changes in the amount of water and raw water turbidity, leading to discharge before or behind. Waste water ahead of the waste of raw water; lag drainage affect the sedimentation tank effluent quality. Due to several times a day to switch the sewage gate valve, drain valve at least once a year, both increasing the labor intensity of workers, but also increased maintenance costs.
