聚内烯酰胺作为高分子混凝剂对水中悬浮物的行为服从朗格茂等温吸附式,并以架桥方式使水中悬浮物结成聚集体以拥挤沉降形式下沉,本文从上述两个基本观点出发,推导出聚丙烯酰胺处理高浑浊水时,混凝剂剂量与浑液面沉降速度的关系式:从而求得最佳剂量与水中含沙量的关系式: C_0~(0.5)=K~(0.5)Γ_mS 或 C_0=KΓ_m~2S~2和最优剂量与含沙童的关系式: C_ρ~(0.5)=0.61K~(0.5)Γ~mS 或 C_ρ~(0.5)=0.37KΓ_m~2S~2 C_ρ~(0.5)=0.51K~(0.5)Γ~mS 或 C_ρ~(0.5)=0.26KΓ_m~2S~2并通过试验数据予以验证,将试验求得最优剂量来指导生产。
The behavior of polyalkenamide as a polymer coagulant in suspended solids in water obeys Langmuir adsorption isotherm, and bridges the suspension of suspended solids in water to sink in a congested subsidence form. From the viewpoint, the relation formula between the dose of coagulant and the surface sedimentation velocity of the mash was deduced when polyacrylamide was used to treat high turbid water: thus, the relationship between the optimal dose and sediment concentration in water was obtained: C_0~(0.5)=K ~(0.5)Γ_mS or C_0=KΓ_m~2S~2 and the relationship between optimal dose and sandy boy: C_ρ~(0.5)=0.61K~(0.5)Γ~mS or C_ρ~(0.5)=0.37KΓ_m~ 2S~2 C_ρ~(0.5)=0.51K~(0.5)Γ~mS or C_ρ~(0.5)=0.26KΓ_m~2S~2 and verified by test data. The optimal dose was obtained from the test to guide production.
