摘　　要：本文提出平流式沉淀池的理论最大产水量是沉淀试验中的u_0^(max)值.作者通过分析认为目前我国平流沉淀池具有挖潜增产的能力.并认为平流沉淀池与斜管沉淀池的截留沉速不相同,斜管池的表面负荷率与截留沉速之间的计算式为Q/A=u_0(1+lcosθsinθ/d),我国斜管沉淀池的截留沉速是0.13～0.23mm/s.This paper shows that the value of Ur,'18' in sedimentation experiment can be taken as the theoretical maximum output of a horizontal sedimentation tank (HST). By the author's investigation the potential capacity of most HSTs in this country can be developed and the catchment velocity of HST is distinct from that of sedimentation tank with laminar module. For the latter the surface loading rate can be calculated by formulaQ/ A = u0 (1 +l/d cosθsinθ) from catchment velocity, which ranges from 0. 13 to 0. 23 mm/s designed in this country.
