Problems solved by technology

The growth of microorganisms is greatly affected by the environment, such as PH value, temperature, air pressure, dissolved oxygen in water, etc., when the existing measures are used to treat eutrophic seawater, the activity of complex bacteria cannot be guaranteed, resulting in eutrophication. The treatment efficiency of nutrient seawater is low, so we designed a method for treating eutrophic seawater with complex bacteria to solve the above problems

Abstract

The invention discloses a method for treating eutrophic seawater by using compound bacteria. The method comprises the following steps: preparing the following raw materials: bacillus subtilis, rhodopseudomonas palustris, acinetobacter calcoaceticus, saccharomyces cerevisiae, alcaligenes faecalis, bacillus megatherium, molasses and the balance of aqueous solution, dissolving molasses in water, adjusting the pH value to strong acidity to prepare a culture medium of a composite strain, carrying out sterilization and disinfection treatment on the culture medium, sequentially inoculating various strains into the prepared compound bacterium culture medium for fermentation culture, adjusting the pH value to be slightly reduced, carrying out anaerobic fermentation treatment on the compound bacteria, periodically detecting the quality of the compound bacteria, putting qualified bacterial colonies into seawater, and blowing dissolved oxygen into the seawater through an air pump in the putting process. According to the invention, rich organic matters and some mineral elements in the water body can be rapidly decomposed and degraded, eutrophic seawater is prevented from being formed, and waterbody pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of seawater treatment, in particular to a method for treating eutrophic seawater with complex bacteria. Background technique [0002] Seawater eutrophication refers to the phenomenon of water quality pollution caused by excessive nutrient salts such as N and P in marine water. The essence is that due to the loss of balance between the input and output of nutrients, the distribution of species in the aquatic ecosystem is unbalanced, and species grow wildly, which affects the flow of material and energy in the system and destroys the entire marine water ecosystem. The prevention and control of eutrophication is the most complicated and difficult problem in water pollution treatment. This is because: ① the complexity of pollution sources, the nitrogen and phosphorus nutrients that lead to eutrophication of water quality have both natural and man-made sources; both exogenous and endogenous. This brings difficu...
