二沉池设计补正

AMENDMENT TO DESIGN OF SECONDARY SETTLING TANK

静沉试验法是常用的二沉池设计方法 ,但是仍存在一些问题。在分析大量有关资料的基础上 ,对该法作了较深入的研究。结果表明 ,静沉试验法能够体现二沉池的实际沉降行为 ,但对浓缩时间的解法需要加以纠正。该设计方法可以更好地应用于优化设计之中。

Though Talmadge\|Fitch method is usually used for design of secondary settling tank,there are still some problems in it.A deeper study of this method is carried out on the basis of analyzing lots of relevant data.The results show that Talmadge\|Fitch method can represent the actual settling process in secondary settling tank and the solution of concentration time needs to be corrected.Talmadge\|Fitch method can be well applied to the optimal design of secondary settling tank.
