The settling law of the new sedimentation facility——a sedimentation tank with seclined plates—— is observed and searched in this test.The settling principle of the new sedimentation facility is different from that of traditional sedimentation facility. The pricipitation of suspended floces is accelerated by means of the circle—flow—action formecl by delined plates.Having done experiments,we found that the concentration of the suspended matter flowing out of the declined plates decays in a exponent form as the...

The settling law of the new sedimentation facility——a sedimentation tank with seclined plates—— is observed and searched in this test.The settling principle of the new sedimentation facility is different from that of traditional sedimentation facility. The pricipitation of suspended floces is accelerated by means of the circle—flow—action formecl by delined plates.Having done experiments,we found that the concentration of the suspended matter flowing out of the declined plates decays in a exponent form as the nambers of the declined plates increased. We also found that the removable limitation of the suspended matter concerns flocculative characteristics of the floces.

本实验研究是考查新型沉淀装置—翼片斜板沉淀装置的沉淀规律.这种装置的沉淀机理不同于传统的沉淀池,悬浮絮凝体在斜板翼片造成的环流作用下,加速沉淀.通过实验发现,由翼片槽内流出的悬浮物质浓度随翼片格数增加呈指数衰减,同时发现去除悬浮物质的极限程度与悬浮絮体的絮凝持征有关.

The electrical resistivity of two kinds of rocks: sandstone and limestone, is measured under different saturation (oil or water), and the changing curves with regad to the saturation are presented. The measured results show that: The resistivity decreases in exponent form for the sandstone of saturated water; The resistivity decreases in logarithm form for the sandstone and limestone of saturated oil. The theoretical analyses and discussion is proposed to explain the experimental result, put forwarded the relevant...

The electrical resistivity of two kinds of rocks: sandstone and limestone, is measured under different saturation (oil or water), and the changing curves with regad to the saturation are presented. The measured results show that: The resistivity decreases in exponent form for the sandstone of saturated water; The resistivity decreases in logarithm form for the sandstone and limestone of saturated oil. The theoretical analyses and discussion is proposed to explain the experimental result, put forwarded the relevant influence factors and mechanism, and the theoretical curves give a good fit of the experimental result.

在不同的油水饱和度下测试了砂岩和灰岩样品的电阻率值.测得了它们随饱和度变化的不同规律.饱水砂岩电阻率随饱和度均呈指数下降;而饱油砂岩、石灰岩电阻率则随饱和度呈对数下降.并对实验结果进行了理论分析和讨论.提出了相应的影响因素和机理,且给出了较好的拟合曲线.

The removal ability to TN, TP from polluted water in Lake Caohai by eight species submerged macrophytes including Potamogeton crispus, Vallisneria spiralis, Myriophyllum spicatum, Ceratophyllum demersum, Potamogeton pectinatus, Potamogeton maackianus, Chara sp., Edodea canadinsis were studied in this paper. Results shows that each species has great ability to remove TN, TP. During the 12 day experiment period, the removal percentage on TN, TP is 87.7%, 81.4% respectively.The regression relation...

The removal ability to TN, TP from polluted water in Lake Caohai by eight species submerged macrophytes including Potamogeton crispus, Vallisneria spiralis, Myriophyllum spicatum, Ceratophyllum demersum, Potamogeton pectinatus, Potamogeton maackianus, Chara sp., Edodea canadinsis were studied in this paper. Results shows that each species has great ability to remove TN, TP. During the 12 day experiment period, the removal percentage on TN, TP is 87.7%, 81.4% respectively.The regression relation of TP concentration and time is put emphasis on in this paper. The formulation of the regression equations is y=a e -bx (a>0, b>0) , which suggests that TP concentration in water declined in negative exponent form with the time continuing.The relation of TP concentration and removal rate to TP is studied too. The v TP equation of each species is given and their formulation is y=a e bx (a>0, b>0), which shows that within the given TP concentration range (0.14 ̄0.37 mg/L), the removal rate of each species increases with increasing TP concentration. Furthermore, the use of TP t and v TP curves for restoration of aquatic macrophytes is discussed.
