Complex flocculant PASS has the abilities of neutralizing electric charge and flocculating. The experimental results show: it is feasible that the emulsion wastewater can be treated into qualified discharging water. The dosage of flocculants and pH value have been optimized by coagulation experiments. In addition the mechanism for emulsion wastewater has been studied by using Perron timed complex colorimetric method and neutralization method. Aiming at characteristics of high concentration and high CODCr emulsion wastewater the technology that emphasized on coagulation-precipitation twice has been proposed in this paper.

In this paper, we give explicit constructions and formulations for harmonic maps from R1,1 into classical real semisimple Lie groups by using Darboux transformation. We also discuss pluriharmonic maps from complex manifoldsinto symmetric spaces and Willmore surfaces in Sn. By converting geometric conditions satisfied by these maps into integrable systems, and using the the-ory of integrable systems, we give explicit constructions for pluriharmonic maps from complex manifolds into symmetric spaces and the Willmore surfaces in Sn respectively. Finally, we classify hypersurfaces in Sn+1 with three distinct prin-ciple curvatures and zero Mobius form using the theory of Mobius geometry. The paper consists of four chapters.
