Abstract
An algal biofilm harvesting method capable of reducing release of planktonic microalgae includes the following steps: S: constructing an algal biofilm treatment system; S: calculating a cutting area; S: harvesting microalgae biomass; and S: cyclic harvesting. By constructing an algal biofilm treatment system, a surface of an algal biofilm can be regularly cut to harvest microalgae biomass, thereby keeping activity of the biofilm in a best state all the time. In addition, the harvested microalgae biomass can be used as a high-quality substrate for subsequent fermentation, which can achieve resource saving. Quality attainment of effluent from a sewage tank with planktonic microalgae as a suspended solid indicator can be achieved, the treated effluent can be prevented from deteriorating due to an increase of the planktonic microalgae, and a risk that the planktonic microalgae in the effluent of the algal biofilm affects a subsequent treatment process is reduced.
