When pH is 10, adsorption time is 30 min, dosage of bone char is 0.6 g/L, the original concentration of As in drinking water is 0.5 mg/L, As removal can reach 95.2%. The adsorption behavior is fitted both with Langmuir and Freundlich isotherm. The adsorption mechanism is supposed to be Ca—OH functional groups combined with anion. And there may occur the co-precipitation between calcium hydrogen arsenate and hydroxylapatite in the aqueous solution, and ions also exchange. The saturation adsorption capacity of As reaches 4.688 mg/g. Indexes of effluent are in good agreement with the WHO stringent drinking water standards (0.01 mg/L).

Based on the Saint-venant equations describing the channel flow movement, the nonlinear algebraic equations derived by the use of Preissmann weighted implicit four-point scheme are solved with the Netwon-Raphson method. A combined Gauss main-element elimination method with compress-storage technique is proposed. The relaxation iterative method for solving branch river networks is extended, which can turn the problem of any complex river networks into the problem of a series of single rivers. The coupling of hydraulic model with water quality model is built up. The combined model was applied to a large complicated river networks with numerical hydraulic structure which influenced by strong tide, storm and heave rain. Visualization of computational results is realized by means of MapInfo, which displays the computational results in fast, convenient and accurate way.
