Effects of extracelluar polymeric substances, Ca~(2+) and pH on bioflocculation;

Study on preparation of N-Alkyl triazon methyl starches and their flocculation;

Initial Experiment about the Flocculation of Pectin in Mixed Juice;

A review on flocculation of fine suspended sediments and its controlling factors in the Yangtze River estuary;

Phenomenon of bio-flocculation in activated sludge of surfactant wastewater;

Study on treatment of wool washing effluent by bio-flocculation process

The mechanisms of bio-flocculation,bio-sorption and zinc-removing by the metabolic product(H_2S)of sulfate reducting bacteria(SRB)are presented in detail.

At the same time, by measuring the oxygen uptake rate, it proved that there was obvious bacteria activity in chemical and biological flocculation system.

Results obtained show that (1) Effective EM rejuvenation is successful through the use of honey, molasses as well as high concentrated organic wastewater respectively; (2)EM addition to activated sludge system can improve the treatment efficiency of the system; (3)Rejuvenated EM solution exhibits biological flocculation characteristic.

The chemical-biological flocculation(CBF) process was used to treat municipal wastewater in Shanghai,and the effect of its return sludge on pollutant removal was studied through stopping chemical addition,simulating different return sludge ratio,and analyzing extracellular polymeric substances(EPS).
