一、天津水厂应用双层滤池情况双层滤池在天津水厂于1954年开始应用,但由于滤料流失,管理不善,用后不久就停止了使用。1961年再度应用,仍不理想。后来接着做了些工作,现主要分为两个阶段来介绍。(一)1964年天津市自来水公司与有关单位合作,在芥园水厂进行试验,至1966年底结束,并组织了鉴定,认为有推广价值。1.模型试验结果(1)在滤前水浊度10毫克/升,滤后水浊度小于3毫克/升情况下,得出砂滤料最
First, the application of double-layer filter tank in Tianjin Water Plant The double-layer filter tank began to be used in Tianjin Water Plant in 1954, but due to the loss of filter material and poor management, it was stopped shortly after use. Reapplying in 1961 is still not ideal. Later, I went on to do some work. Now I mainly introduce it in two stages. (a) In 1964, the Tianjin Water Supply Company cooperated with the relevant units and conducted tests at the Mustard Water Plant until the end of 1966. It organized the identification and believed that it had promotion value. 1. Model test results (1) In the case of water turbidity before filtration of 10 mg/l, and filtered water turbidity of less than 3 mg/l, the most common sand filter is obtained.
