Ferric-polysilicate coagulant is a new type of inorganic polymer flocculants; its made up by adding ferric to polysilicate-sulfate, and it has not only the property of electricity neutralization of iron, but also the property of adsorption and framing of polysilicate-sulfate. It is more efficient than traditional flocculants in depurating wastewater.

The results show that BS 460MPa grade reinforced bar can be produced all from Q235 or 20MnSi billet by the remained heat treatment process but the production cost of the former is lower. When the water pressure minishes, the intensities of reinforced bar reduce; the higher the temperature at the entrance of cooling bed is, the lower the intensities are. Therefore, the commendatory process parameters are that five stages coolers should be opened, water pressure should be all 1.8～2.0MPa and the temperature at the entrance of cooling bed of Q235 reinforced bar should lower than 650℃. The typical microstructure(Q235): the surface layer is tempered sorbite; the transition layer is pearlite and ferrite, and the partial ferrite is acicular; the core is pearlite and ferrite and the grain fineness is 8～10 grade. The yield strength is reduced by 10～20MPa after natural ageing and it can be simulated by artificial ageing(100℃×2h or 200℃×1h).

结果表明，Q235和20MnSi钢都可以利用余热处理工艺生产出性能合格的钢筋，但前者的生产成本较低；水压减小，钢筋强度降低，上冷床温度越高，强度越低，推荐5段水冷器全开，水压均为1.8～2.0MPa，Q235钢筋的上冷床温度应控制在650℃以下；钢筋典型的金相组织（Q235）表层为回火索氏体，过渡层为珠光体+铁素体且部分铁素体呈针状，心部为珠光体+铁素体，晶粒度8～10级；自然时效后屈服强度下降10～20MPa，用人工时效可以模拟自然时效，工艺是100℃×2h或200℃×1h。

In this paper, a total of 56 relatively nonpoint source pollution sediment samples were collected from the tidal flats of the Jiuduansha shoal and the Chongming island of the Yangtze river estuary. The main properties i. e., grain size distribution, contents of DCB (dithionite citrate bicarbonate extracted iron Fe(subscript d, AAO extracted iron Fe(subscript o, total Fe, DCB extracted Mn Mn(subscript d, total Mn, organic matter, magnetic susceptibility of the samples, as well as the concentrations of Cu, Zn, Pb, Cr, Cd and Ni in the samples, were determined. Basing on the data, the relation of the sediment properties to heavy metal concentrations was evaluated with pearson's rank and partial rank correlation analysis.
