Embodiment 1

[0028] Embodiment 1 Polyaluminum Chloride is to the removal effect of Pyrodinium catenella

[0029] Add different concentrations of polyaluminum chloride to a concentration of 10 6 In the algal solution of Gymnodinium catenella, the concentrations were 10, 20, 30, 50, 70, and 90 mg / l; the removal effect of algae cells was calculated at 3 h and 24 h, respectively. From figure 1 It can be seen that at the 3rd hour, the removal effects of polyaluminium chloride at various concentrations on Pyrodinium catenella were all above 80%. At 24h, the algae cells in each group rebounded to varying degrees, and the removal rate decreased. Among them, 10, 20, 30, 50mg / l, the rebound effect is obvious.

[0030] The preparation of embodiment 1 Bacillus subtilis fermented liquid

[0031] Inoculate a single colony of Bacillus subtilis in LB liquid medium and culture it in a constant temperature shaking incubator with a temperature of 30°C and a shaker speed of 180r / min for 1 day, and then tr...

Abstract

The invention provides a method for inhibiting algae growth by coupling a coagulant and algal inhibition bacteria. The coagulant is polyaluminium chloride. The algal inhibition bacteria are bacillus subtilis, and the algal inhibition bacteria are called as Bs bacterial strains for short. Experimental data show that the combined use of the polyaluminium chloride and the algal inhibition bacterium fermentation liquor has an obvious inhibition effect on algae cells, the continuous algal inhibition time is long, and a re-dissolution phenomenon hardly occurs. The method using polyaluminium chlorideis a method for more thoroughly inhibiting the red tide by combining a coagulant and algal inhibition bacterium fermentation liquor which are common in a conventional wastewater treatment process, the algicidal effect is remarkable, and the phenomenon of re-dissolution of algal cells can be effectively avoided.

Description

technical field [0001] The invention belongs to the field of marine environment protection, and in particular relates to a method for inhibiting the growth of algae through the coupled use of a coagulant and an algastatic bacteria fermentation liquid. Background technique [0002] Red tide is one of the serious global marine natural disasters, which has attracted great attention from all over the world. In recent years, the pollution of my country's coastal waters has intensified, the problem of eutrophication in some sea areas has become prominent, and red tide outbreaks have become increasingly frequent, which has brought serious ecological, resource and environmental problems to coastal waters, and caused huge economic losses. A major threat to sustainable economic development. Therefore, it is one of the major problems to be solved urgently in the field of red tide prevention and control to study new efficient and environmentally friendly red tide control methods. [00...
